ABCs of How We Learn… O is for Observation – Building STEM Identities in the Classroom

In The ABCs of How We Learn, Schwartz, Tsang and Blair dedicate the O chapter to Observation. Specifically, they are addressing Bandura’s Social Learning Theory. Social learning theory considers how both environmental and cognitive factors interact to influence human learning and behavior and at its core is the idea that humans will model after those who are similar, high-status, knowledgeable, rewarded, or nurturing figures in our lives.

The classic experiement that is referenced is the Bobo doll experiement, where children who observed an adult beating up the Bobo doll were more likely to mimic the same agressive behaviors

Learning through observation is certainly something we see with learning that involves kinesthetics. It is also the foundation of the Montessori Method. In our physics classrooms, however, it is not necessarily immediately relevant. The mere observing of the teacher engaging with a complex derivation is not going to translate to meaningful learning. Additionally, the original theory carries with it some challenges, specifically that there is a lack of clarity on the cognitive processes, a likely overemphasis on observation and a difficulty in predicting behaviors. Just because a child observes something doesn’t necessarily mean they will reproduce the behavior, or reproduce the intended behavior. Nevertheless, we do know that when modeled behaviors are also paired with verbal reasoning “I’m going to do this because…. so that… ” and so on the intended learning is more likely to translate.

So I am going to choose to diverge this post a bit from the original text.

The key idea behind social learning theory is that humans will model after those who are similar, high-status, knowledgeable, rewarded, or nurturing figures in our lives. For a student this translates to friends, popular peers, respected teachers and caring adults. Much could be said here regarding the norms chapter and the choices we make as educators to build those norms in our classroom. What I’d like to focus in on, however, is the idea of modeling after those who are similar and knowledgeable. Specifically, I’d like to take about the importance of representation in the physics classroom and the formation of STEM identity.

We discussed this a bit in the Belonging post, when we consider a person’s identity we know its composed of many different positionalities.

When we add the layer of a STEM identity, a huge piece of that web is, indeed belonging. Belonging can be threatened by imposter syndrome and sterotype threat, and it can be enhanced by being “seen” as a STEM person by one’s peers, faculty members and family. In short, a person’s STEM identity is highly dependant on the same people who they might choose to imitate under the theory of social learning.

One of the simplist and most powerful activities I have used in my classroom is the STEPUP Careers in Physics lesson. You can access it online. In the activity you begin by having students brainstorm careers a person might have with a bacholer’s in physics. Then, students engage in a short career match survey. After submitting, they are “matched” with people who are like themselves, but who happen to have a degree in physics in a variety of fields. Although the lesson is explicitly teaching, “you can do anything with a physics degree” due to the intentional selection of diverse representation in the available bios, the lesson is also implicitly showing “you can be anyone and have a physics degree”

In Gholdy Muhammed’s book Cultivating Genius, she outlines her Historically Responsive Literacy framework. In the framework one of the core ideas is that equity is not a one-off lesson or PD session, but rather something that is engrained at the center of our work. The framework identifies four areas: skill, what do we want students to be able to do, but also identity (who am I, who do I want to be) intellect (gaining new and authentic knowledge about the world) and criticality, which she defines as capacity and ability to read, write, think, and speak in ways to understand power and equity.

When I first learned about this framework I started incorporating what I dubbed Identity Encounters in my classroom where we took time to learn about different, current people in physics, who came from a variety of backgrounds. While we ultimately learned about their work in the field, we inevitably also got to hear about their challenges as well.

The underrepresentation curriculum project takes things a step further to explicitly talk about injustice and inequities in STEM. Research has shown that when we make these explicit in discussion with students we are able to mitigate the effects of imposter syndrome and stereotype threat. I’ve run these lessons as periodic lessons between physics content as well as a longer unit during which we also watched Hidden Figures while examining the themes we discussed in class.

Physics educators such as Elissa Levy have gone so far as to redesign their curriculum in such a way so as to include a more full history of the physics we are teaching, rather than just the classic, Western-European cannon.

We know that teaching physics is an uphill battle where some students decide they aren’t fit for the course from day one because they already have a deeply embedded identity of not being a math person. I firmly believe that when we can demonstrate that science is done in community over isolation, that failure is much more common than strokes of genius, and that there exist many different paths and identities to studying physics, our students can begin to learn and identify that they, too, can become a physics person.

ABCs of How We Learn… N is for Norms

Today was the last day of school for seniors. I have my students fill out an exit survey in which I ask them what they were most proud of, what surprised them and what was the most important thing they learned this year. I was really excited to read some of my student responses. More on that in a moment.

Norms are the rules of the game. They are what dictate conduct in social settings. In society they are often the unwritten rules, very often defined by cultural norms. I remember when I went to France for my honeymoon. A lot of Americans go to France assuming the French are rude. The reality, as my Aunt and Uncle explained to us, is that Americans go to France assuming they can act like Americans, rather than learning the cultural norms, and this becomes off-putting. In the US we expect our waiter to check in when we sit down and when we are done with our food. In France, the restaurant expects you to enjoy the experience for as long as you need or would like. You call the waiter over when you are ready to order and when you’re ready for the check. No one is going to rush you out of the restaurant with a check, you can sit and talk as long as you like!

I bring up this example for two reasons. One, it is an example where the norms dictate the expectations and behaviors, but secondly, the conflict in expectations due to cultural differences is what can lead to one or both parties either being upset or in active conflict.

Conflict very often arises when the unwritten norms of one person/group do not match the other. This is why it is especially important in the classroom setting to make these norms very much written and visible.

One set of particularly important norms are the ones we use regarding our content. The previous post mentioned the scientific practices from NGSS. These are excellent norms to have as part of learning, discovering and justifying. We must ask ourselves, what is the norm for engaging in learning activities? Is the norm that the teacher is the keeper of knowledge and the students are passive receptacles? Or are the students active participants? Are they expected to continue asking themselves “how do I know this”? Are they expected to give answers based on intuition or based on evidence? The norms we set for how we engage with science in our classroom are the norms we are teaching our students are part of the scientific community.

This is part of what I really enjoy about Building Thinking Classrooms. Many of the strategies turn what students know as the norms of school on its head. Specifically defronting the classroom, the consolidation process and note-making.

Since Listening and Sharing is also a critical feature of education, norms for discourse are particularly important in the classroom.

STEP UP has a great poster of norms for the classroom:

EQUITY Share air time equitably. Know yourself, balance your listening and talking. DIFFERENCES Value differences. Remember that your perspective is not the only one, and that we all face different challenges. EVIDENCE Argue using evidence. Back what you have to say with data. SAFETY Make sure everyone feels safe. Safe is not the same as comfortable. Ensure that there are ways to report problematic behavior. DISCOMFORT Discomfort is okay. Identify your learning edge and push it. OWNERSHIP Own your impact. Your intentions may not be the same as your impact. COMMUNITY Create a sense of community. Acknowledge others and do not isolate anyone.

This school year I found that students were very uncomfortable having conversations or working in groups with students who were not their besties coming in. Sometimes holding the norm looked like actively telling students we weren’t going to comment on “good” or “bad” groups. Other times this meant actively coaching students on engaging in discourse with one another. It felt like an uphill battle all year.

But then the end of year comments came in:

Particularly as an AP teacher, it can be easy to get caught up in the exam, the scores, the grades. After all, its one of our primary measures of success. But honestly, for myself, success also looks like these student reflections. It looks like students telling me that tests are feedback, and that they learned it’s ok to fail sometimes. Because those lessons? Those are the ones that last a lifetime.

ABCs of How We Learn… M is for Making

Different types of oscillators featured as scientist peg people (and one physics teacher) for FermiLab’s Family Open House, Feb 2018

Remember when we were all stuck in our houses in the spring in 2020? With few places to go and a lot of time at home all of a sudden everyone was making their own bread and even taking a crack at artisan soughdough.

When we have a chance to truly create something, we find joy and satisfaction in seeing the fruit of our labor. We can then invite others into our joy by sharing what we’ve created, and in the process we find new challenges to tackle and overcome.

We tend to most often connect making in an education setting to informal educational settings: camps, museum programs, clubs etc. More recently we’ve seen the explosion of maker space centers not only at institutions of learning, but also in libraries and museums.

The roll-out of NGSS included Science and Engineering Practices, all of which clearly have their place in “making”

Why is Making Important for the Classroom?

Practical Knowledge – Making, especially when tied to a relevant, real problem, gives students the chance to see the application of their content to their real life. It also has a great side effect of teaching students some knowledge and skills that they might find useful later. The electric house project gets students stripping wires and wiring them together. I personally will never forget the “hosehold wiring” unit in my own AP class where our final project was to build a lamp. Years later when the plug on my vaccuum broke, I felt fully confident in myself in buying what I needed to replace the plug.

Interest & Identity – We know from the research that if a student can see themselves as a science person, they are more likely to persevere in science and choose a STEM major. Having the opportunity to create something that works and is grounded in scientific principals which is shared with the community provides ample oportunity to find strengths in a variety of scientific competencies and receive that recognition from others which is a critical compoenent to identity formation

Dispositions Towards Failure – We know that failure is at the foundation of growth and success, but too often in school many of our brightest students find themselves fleeing failure at all costs. This can result in a fear to take risks and speak up, which ultimately stunts their own growth. In order to solve a problem and design a solution students will inevitably go through a process in which failure is inevitable. When students can see that this is part of the process, even in a science classroom, their concept on what failure means can shift in that academic setting.

What Can Making Look Like?

In much of our classroom settings making often looks like projects, and these projects (as well as our labs) allow students to engage in skill-building beyond just the content.

There are some amazing teachers out there who are incredible at problem-based learning and projects, my personal toolbox is somewhat limited. I love my AP Physics “Physics Of” projects for the end of the year as well as the AP Physics C Mastery projects to provide APPC students who previously took APP1 the chance to demonstrate their competence from the previous year. There’s also the classic egg drop activity, mousetrap cars and most recently, I’ve assigned students electric houses. Beyond the Egg Drop is a book that was recommended to me a few years ago, available from NSTA. The projects in the book have been designed in such a way to align with the engineering practices.

I believe that we start with some of the core ideas: providing student agency, opportunities for creativity, and a backdrop grounded in supporting student planning, execution, evaluation and presentation. The key is to find opportunities to let this happen.

The ABCs of How We Learn: L is for Listening and Sharing, Strategies to Enhance Group Work

I have a saying for students, “The 100% is in the room”.

What I mean by that is that, collectively, the 100% exists. Not necessarily within one student, but when students engage in true collaboration, very often, the 100% exists.

L is for Listening and Sharing and is based on the idea that we learn more together than we do alone.

This would then suggest the power of working in small groups. However there are a few flaws that teachers fall into very often:

  1. Putting students in small groups alone is not going to lead to learning. Students need to know how to speak and listen to one another.
  2. Group selection can be powerful, but students will make assumptions about why they are in a certain group, which will influence their behavior in the group

Setting Norms for Group Behaviors/Interactions

We have all seen this in our classrooms and even in PD sessions or workshops. Some groups function together excellently, while others flounder fantastically. Setting the norms, expectations and even scaffholding the conversation is a critical component of our work.

Protocols

When we implement highly structured protocols we provide students with a predictable framework for engagement. The book Protocols for All is a great place to start and has some ideas that you’ve probably encountered. Many of these protocols are what you might classify under “ice breakers” or “team building activities.” Research has shown that taking the time to get students to work collaboratively outside of the specific content area supports their ability to work collaboratively when its time to get content-specific. What I like about a lot of these protocols is the emphasis on listening because often our best talkers are our worst listeners. In a profession that frequently values and rewards extraversion, it’s really important that we take the time to hone the seemingly less charismatic skills.

I just so happened to run across this graphic from Zaretta Hammond, author of Culturally Responsive Teaching and The Brain, that outlines a progression of protocols to support student discourse and equity.

She is leading an online summer PD on this topic that you can currently register for and has a previous article with additional ideas described here

Group-Worthy Tasks

Along the same lines, the kind of task we select is critical. This has been named “group-worthy tasks”. A group-worthy task has a few key features. First, it cannot be completed in the time allotted alone, the group members must depend on each other. This requires the task to have a certain level of complexity. Second, the task must have multiple entry points for success. This means that there is a way for the students who are at a lower performance level to positively contribute, but there are higher order thinking tasks available for the upper-performance level students to address.

Marta Stoeckel and Kelly O’Shea wrote a fantastic article about Group-Worthy Tasks for The Physics Teacher in 2024. A few additional features I’d like to bring your attention to is assigning group roles of Skeptic, Facilitator, Summarizer and Navigator and providing students with a role-card during the task. The second feature is discussions around what makes someone good in science (asking good questions, making astute observations etc).

Mitigating Student-Assigned Roles of “Smartness”

In addition to frequent discussions around competencies in science and shared norms, utilizing visibly random grouping can help alleviate any self-assigned roles students create. Regardless of whether or not the groupings were random, students will often assume they’ve been placed in a group by the teacher to either carry the team, or because they are the kid who needs help. When groups are chosen randomly, and visibly (drawing cards, using a random group generator online) students are unable to make these assumptions as a choice you the teacher made. Visibly random grouping is one of the tenets in Peter Liljidahl’s Building Thinking Classrooms. I’d like to address another key aspect of his work that is critical for the effectiveness of groups, listening and sharing. When work is complete on the boards, it is now time for the teacher to implement Just in Time Telling while continuing to engage student thinking. It looks like this:

  1. The teacher re-groups the students away from their boards, perhaps in the center of the room or on the side. The teacher may share some key noticings about the work at this point.
  2. The teacher informs students we are going to “Take a walk”. The teacher moves students to a particular board she has selected in order to discuss one step of the problem that has been completed correctly.
  3. The teacher directs students to this particular piece and poses the question “turn to someone next to you and discuss what this group was thinking when they wrote this part down”
  4. The teacher then asks “someone not in this group, share with us what this person was thinking”

What do to With That Really Smart Student Who Can’t Listen

A few years back I had a group of AP students where the dynamics couldn’t have been more disparate. I had a few hyper-competitive, confident, brilliant students who would do all of the talking and solving, and then I had a few students who were quiet and thoughtful but also lacked confidence. In more than one instance the confident students convinced the quiet ones that their incorrect answer was the answer. So I tried something new. As students worked in groups to solve a problem I assigned the following roles:

The quiet students were required to do all of the writing on the whiteboard. (By the way, having a shared visual also enhances the team-experience!) They were welcome to contribute in any way they desired, but the marker was in their hands so they were responsible for the documentation.

The average students were allowed to discuss the problem, but they were not allowed to write.

The confident students were only allowed to ask questions. The way I framed it was that they were in my role as the teacher. They needed to create and frame questions in such a way so as to get their peers to get on the same wavelength that they were on… without actually giving them the answer.

The result of this was pretty cool. At least one of the kids who normally ran the show was super frustrated at first, but its because I was pushing a different skill set. Rather than just solving the problem and talking it through out loud, he now was required to carefully listen to the conversation so that he could ask the right questions to move his classmates along. The quiet students were all required to be active participants, even if they weren’t doing the talking. Since they had to do the recording, however, this required them to be engaged and ask for clarification as needed.

In November 2025, this article was published in The Physics Teacher. In the article the group lays out their summary of suggestions for effective group work based on the current litterature. Their findings are summarized in this guide:

ABCs of How We Learn: Knowledge … To Whom Does it Belong?

One of the most cringe comments I hear from students working in class is “she said that…” When I hear this instead of “what we need to do next is…” or “I know that the answer is … because… ” I personally feel that I have not yet done my job for students. Why? Because students are not yet taking ownership of their knowledge, the answer still rests in my hands, not theirs.

We could argue that the goal of education is to impart knowledge to students, but knowing that our students are not going to remember all things, what knowledge do we truly want them exiting our classrooms with, and to whom does that knowledge belong?

Knowledge is the bedrock for all learning. The more a student knows, they more connections they can make, the deeper they can go with that material. We’ve already discussed that when students can tie new knowledge to previous knowledge, whether its through analogy, elaboration, generation or a hands on experience, the pathway for memory becomes stronger. In the brain, the physical neural pathway is what has literally grown and strengthened.

If we are going to implement strategies in our classrooms to enhance learning, and we are going to do that from a lens of evidence-based practices, then we need to understand the foundational underpinnings of the brain and how knowledge, skills and creativity are built and work together.

Knowledge and the Science of Learning Conversation

The science of learning has its set of cognitive principals upon which learning instruction can be built. Deans for Impact has a nice document that outlines most of them. Below are a few of them:

  1. New ideas are connected to old ones, but students working memory is limited. Therefore so too must be our presentation so as not to overload them.
  2. There exists a core set of facts in any area of study. Once these are memorized, a person can tackle more challenging problems as their working memory is now freed up. (this is the foundation for phonics in Science of Reading and memorization of math facts for fluency)
  3. Learning transfer is difficult as it requires knowledge of deep structure, which is often not apparent to the novice. (This is argument for contrasting cases)

I want to say first, that all of these core ideas are valid and have the research to support them.

Next, I need to say that unfortunately, due to either a lack of nuance or the inevitable polarization of our current society’s expression of social media, there exist some pretty strong feelings that pit science of learning against constructivist teaching as entirely incomparable.

Through Hattie’s research constructivist teaching has an mean effect size of 0.92 which puts it on par with the jigsaw method and strategies to integrate prior learning. Constructivist teaching is designed with the learner at the center, involves active teaching methods and allows students to explore ideas, solutions and explanations and then take action. This is not to be confused with pure inquiry or discovery based learning. Another set of strategies which has come under great scrutiny are the methods developed in Building Thinking Classrooms in Mathematics. The hard-lined science of learning folks argue that having students engage in activities without prior instruction or knowledge is problematic due to the conflict with the previous statements above. Simply put, students are novices, therefore they lack the background knowledge and skill set to engage in a doing or creating activity, and as novices students will not be able to engage in truly meaningful ways that will impact learning. Instead, they will flounder around with great cognitive overload, little success and too much room for mistakes and misconceptions.

I’d like to take a moment to address this in the context of the kind of learning we see in curricula such as modeling and the Investigative Science Learning Environment (ISLE). First, students are not blank slates. They come to us with a wealth of experiences which have shaped the background knowledge they bring to us. None of our students walk into our room with the same background, but there exists a background nonetheless. Both the experiences and the background knowledge need to be acknowledged in order for us to to our job properly, which is why constructivist teaching is student-centered. Second, I’d like to think that in an ideal educational setting our students are able to move from passive receivers of knowledge to active doers and producers of knowledge. In order for this to happen, we must create the environment where experience is central to developing knowledge.

I took on a collaborative project/conversation with another peer at the beginning of the year in which we took the principals from the Dean’s for Impact document and began aligning the principals with strategies and practices from a physics classroom that is centered on active-learning, constructivist pedagogies. If you’re interested you can take a look here.

Knowledge as a Cycle of Experience, Reflection and Testing

David Kolb, psychologist and educational theorist defined the learning process as the following cycle:

This cycle makes sense for any learning we encounter, not just school-learning. Consider perhaps the kid who “doesn’t like school” Very often that student’s dislike for school can be traced to a concrete experience, whether it was a teacher, and administrator or other students. That experience made them notice and feel things about themselves and/or their environment and made them determine that school was not the place for them. Perhaps this meant they withdrew socially or academically. Maybe it means they transfer schools all together. Either way, some action follows which creates a new concrete experience.

As humans we are learning all the time, and that learning is very often starting from an experience rather than a textbook. (Or perhaps the textbook motivates us to seek an experience!) Shouldn’t it only make sense then, that our students’ learning also begins in a place of experience?

In a previous post, Just in Time Telling, I discussed the fact that when a carefully selected and targeted experience is provided to students and then follow up with Just in Time Telling, the learning gains are strongest for the student than with lecture alone, or discovery-based learning alone. (Schwartz & Bransford, 1998) When we then follow up the Just in Time Telling with a testing experiment, we are providing students into the action, doing and ownership part of knowledge. During this phase of the learning cycle student can make a claim, “if ____ then ______ because______” This testing experiment then creates a new concrete experience from which the cycle can begin anew.

What is a testing experiment you ask? A testing experiment can be any of your traditional labs in which you’e asked students to calculate g, find the theoretical period for the flying pig, find the location where the two cars collide and so forth. Rather than making it a “challenge” task, we can reframe these activities as an opportunity to test our current understanding of forces, circular motion or kinematics.

A testing experiment might also look like one of your traditional labs. For example, we have a lab in which students determine if the friction of the wheels of their lab car are negligible. In this case the hypothesis might look like “if the friction is not negligible, then when we attach a mass to the car and allow it to drop, we expect the change in gravitational potential energy to be different from the change in kinetic energy of the car”.

A Paradigm of Ownership and Action is a Paradigm of Equity and Liberation

There is another critical component here regarding this particular concept of learning and discussing ownership. There is something that inherently sits very wrong with me around some of the language in the science of learning that sounds like language and expectations which are ultimately choosing compliance over creation and collaboration, and maintaining the power differential between teacher and student. When we can move students from passive receivers of knowledge to active producers of knowledge we are also transforming the seat of power. In a world in which we continue to have discussions around social justice, equity and power structures it is a natural conclusion that knowledge and the ability to act on that knowledge is also empowerment. Creating a learning environment where students become doers, producers and drivers of their own learning is creating a learning environment where students can become agents of equity and justice within their circles of influence and their communities.

Why is this conversation important?

When students are subject to strict direct instruction, in which students are assumed to be inadaquate at creative thinking until some benchmark base of knowledge has been established, what we are effectively doing is creating a bunch of minds with fantastic routine expertise (solve these exact problems this exact way). This kind of expertise might easily demonstrate strong effect with high grades and high standardized test scores, but what it doesn’t support is adaptive expertise where students can take a set of skills and move those skills to something novel. As is true in most of life, somewhere in the middle there exists the ideal balance. Routine expertise is important for some aspects, but so is adaptive expertise. We need both. I suppose another essay entirely could be written on why this is even more important in the age of AI.

Here are some questions for your consideration:

  • When you consider your classroom environment currently, does your teaching lean more towards the passive passing of knowledge, the active producing of knowledge, or have you struck the balance?
  • When you consider your students and their expectations for your classroom does they lean more towards the passive passing of knowledge, the active producing of knowledge, or have they struck the balance?
  • If there is discrepancy between your environment and your student expectations, how do you resolve this tension?

ABCs of How We Learn: J is for Just in Time Telling – Why Active Learning FIRST is BEST

Memories are stronger when we are able to connect a new experience to a prior one. The concept of “just in time telling” leverages this idea. Rather than dumping a bunch of new information on students, we recognize that students will be able to do more with the new information when we tell them the answer at just the right time.

Curricula in which students are engaged in activities to “discover for themselves” often gets a bad rap from the science of learning community. However, when experiences are paired with the just-in-time telling afterwards, the results are more robust than either method alone. In fact, if we are only lecturing our students are greatly limited by the amount of sense they can make due to their lack of background knowledge. This is often touted as the reason why constructivist learning is a problem, however when the activities are carefully selected and followed by just in time telling, we have provided students the background knowledge in an experience that permits us to then provide a lecture through which they can then make more meaning!

You’ve likely done this before in some context for students. Demos frequently take this experiential role. But what if we made experience before telling the cornerstone of our work? What if we viewed experiences not just as “fun demos” but as critical components to the learning cycle?

Here again is where I am going to sing the praises of the Investigative Science Learning Environment (ISLE) curriculum because it does exactly this! (In ISLE it’s called “Time for Telling”)

During the learning cycle for uniform circular motion students engage in a series of experiments. The first are observational experiments: get a bowling ball moving in a circle on the floor, swing a force sensor in a vertical circle and observe the force readings for the tension in the string, make a constant velocity buggy move in a circle. When I do this with students the next step is to ask them to represent and reason based on their observations. In this case, I ask them to sketch the force diagrams and look for patterns.

One of the key features in this sequence of activities is that the experiences chosen are very carefully constructed to be precise and matched to the intended learning outcomes. At the end of this series of experiments we do, indeed just tell students that in order to move in a circle we require an unbalanced force AND that force is directed towards the center of the circle. I provide my students with the following page for their notes (modeled after notes from Building Thinking Classrooms)

Students are indeed told the correct physics, but since it is after engaging in experiences, the memories should be more robust. This work is then also paired with the elaborative interrogation of the textbook that evening to prepare for the following day.

Today I challenge you to think of one topic where you have started the class by “just telling them”. What is an experiment that students could engage with prior to telling them?

A word of caution: As you take on this exercise I want to strongly discourage you from falling into the “trick your students” trap. A classic example of this is setting up the projectile demo where one ball drops straight to the floor while the other is launched horizontally. Many teachers set this demo up at the beginning of projectiles, ask students to make a prediction, they pretty much all guess wrong, we run the demo and say “aha!”. If we want to create a classroom of belonging, its important to take advantage of any opportunity to provide our students with recognition. In order to create an experience that will enrich our student minds, build their knowledge and support their self-perception, the experiences must be carefully chosen and scaffolded so that the answer we need is the answer we are going to obtain from our students. This typically requires students to engage in data collection in some way, even if that data collection is visual (such as dropping beanbags behind a rolling bowling ball, or observing the direction of an applied force).

ABCs of How We Learn: I is for Interleaving + An AP Practicum for Review

The skeleton for this blog series has been the book The ABCs of How We Learn by Daniel Schwartz, Jessica Tsang and Kristen Blair at Stanford. As I am doing my prep work for my blog series where I include and adapt the ideas within my physics classroom there are a few chapters that don’t quite have a 1:1 connection. In the original book, the authors write chapter I for Imaginative Play. The research is a bit on the weaker side (causation or correlation?) and is focused on the youngest students and their social dynamics. Although we could absoultely discuss the ideas of imagination and creativity in the physics classroom (consider the utilization of movies like Interstellar, or the discussions that launch units in OpenSci ed, for example) I’m going to make the decision to stick to the strategies that I feel most confident discussion. So here I diverge from the text and we will discuss Interleaving.

Interleaving simply means that students are engaging in activities that require them to problem-solve out of the order in which they were taught and/or by jumping around in terms of ideas/topics within a practice set. By requiring students to retrieve from a variety of topics/skills, students create even stronger neural networks in their brain which leads to stronger retention and comprehension.

For example, perhaps you have a homework set that looks like this: 4 balanced force questions, 4 unbalanced force questions where the object is speeding up and 4 unbalaned force questions where the object is slowing down. Interleaved practice would jumble these questions up.

Another example of interleaving is that perhaps students are currently learning about momentum but on a particular problem they are asked to calculate force from a force diagam, then determine the impulse and solve for the change in kinetic energy. In this case students are interleaving entire topics.

The value of interleaving is at its best when implementing similar problems (in terms of deep structure, which may look like different topics on the surface). This allows students to begin to focus on the problem solving structure, rather than the algorithm, and they can begin to notice subtle differences.

AP problems are often a great example of interleaving. Very often students need to pull from multiple units in order to complete the problem. Recently I provided students with this momentum practicum challenge as part of their AP review. The physical task was modeled after an old FRQ, but students were not initially aware of this fact. Students rolled a happy and sad ball down a hotwheel track where the ball collides with a block at the end of the track which falls to the floor.

Students are asked to do the following:

  1. Make a claim: Which ball will result in the wooden block traveling farthest (this should be physics-ly correct)
  2. Gather some evidence and quantify as much as possible. The more things you can quantify (momentum, energy, force, velocity etc) the more points you get! 
  3. Reasoning/Discussion: Does your evidence support your claim? Explain in detail why or why not. For every quantity you measured or calculated you should be able to explain how that piece of evidence supports or refutes your claim! It is possible that you evidence does not support your claim. If it doesn’t examine your videos carefully and look for anything that happened that we were not anticipating.

To “level up the spiciness” students are asked to find a different way to find the ratio of distances. I provide students a hint to drop the balls vertically. The goal here is to investigate with energy methods.

The last level includes the following prompt: The balls rolled down the track and you should have determined the velocity of the ball at the bottom. Assuming the balls are solid spheres (moment of inertia 2/5MR2) determine how much energy was lost on the track from the top of the track to the bottom. 

In this final challenge students are using energy and rotation.

For the “glass of milk” I have students work through the original FRQ and link it up with the practicum they just completed.

This example takes advantage of a number of previously mentioned strategies. In addition to the interleaving we have engaged students in a hands on exercise that ultimately leads to working through a problem with feedback.

ABCs of How We Learn: H is for Hands On – Activate Before Dictate

I don’t think I need to tell a bunch of science teachers the benefits of Hands on Learning, so let’s take this in a different direction: What makes for a hands-on experience that is positively impactful on student learning?

Not all hands on is equal! Hands on activities need to be carefully constructed in order to produce intended impacts. According to the authors Schawtz, Tsang and Blair, An exemplary hands-on procedure “allows students to find meaning and structure rather than copy a symbolic procedure” in other words, hands-on activities are sense-making activities.

In the Investigative Science Learning Environment (ISLE) framework every cycle begins with observational experiements and those observational experiments very often involve some sort of hands on experience.

Take the introduction to forces, for example. Students are asked to hold a light and a heavy object in each hand, palms up. Next, they are asked to sketch a diagram that shows the interactions on each object. Most students quickly indicate that both the hand and the earth are interacting with the objects and correctly reason that these forces must be equal due to the fact that the objects are not moving.

This seemingly simple activity is incredibly rich. Not only are students constructing the correct understanding of the fact that an object at rest experiences balanced forces, they are also beginning to understand the concept of a normal force (though we aren’t calling it that yet) and the begining of creating a force diagram. All by simply sketching what they feel through observation.

Another excellent example from the ISLE curriculum is the introduction to work and energy.

I provide students with an individually wrapped life-saver mint and ask them to think of ways in which we can crush the live-saver. The ideas of dropping it (or dropping something on it), throwing it (slingshotting it), and smashing something into it all come about and then I give students some materials to do it. However, I include one very critical instruction: there likely exists a way that you could drop it, throw it etc. in which the live saver doesn’t break. I want you to find the edge between breaking it and not breaking it.

Through executing these hands-on, very simple excercises, we are able to construct the idea that candy-crushing-ability (CCA…aka energy) can be increased as we increase the force and the displacement, but ONLY so long as those two attributes are parallel. In addition, in order to “save” the candy from say a falling brick, we need to exert a force in the OPPOSITE direction of the movement to reduce CCA.

In both cases we could have simply taught “here’s how you draw a force diagram” “this is the definition of normal force” “work is the dot product of force and displacement” but none of these definitions ground students in the physical real-world that we are describing in diagrams and mathematics. The hands on experience gives students additional neural pathways and memories to access as they learn new information and tie it to previous experiences.

There are a camp of explicit-instruction/science of learning enthusiasts who will enter into aguments against this kind of constructivist learning because students, as novices, lack the background knowledge to efficiently get to the learning/conclusions we want them to reach in the classroom. I’d argue that the examples provided here are exactly what is called for in direct-instruction. The examples are carefully crafted, the tasks for the students are simple, and after students have done the requested work we as the teachers will indeed tell students exactly what they need to know.

One of the biggest challenges/risks around hands on learning is that students may not notice what we need/intend them to notice. The most critical component here is that these tasks are carefully planned, and in many cases may even appear overly simplistic, like the examples above.

ABCs of How We Learn: G is for Generation

Generation is all about working that brain muscle. The more often we need to remember something, the more likely we are to remember it!

In the information processing model of cognition, this is the retrieval portion

Retrieval has a great deal of benefits when used correctly and there are a lot of misconceptions about retrieval.

First of all: you cannot retrieve what has not been encoded into long term memory. Why is this important? Because asking students to write down what they remember from today’s lesson as an exit ticket is not retrieval. That information is still in the maintenance rehearsal stage. What is rehearsal is asking them to write down two things they remember from yesterday’s lesson.

Retrieval isn’t just good for memories, it also raises student confidence and lowers testing anxiety! In my own classrooms as well as in the classrooms of colleagues, we’ve seen that when students engage in retrieval exercises often, student confidence in the classroom increases significantly. This is particularly true when you ask students to regularly engage in “brain dumps” where they write everything down they remember about a particular unit. As the unit progresses they should be able to write down more and more. It creates a visible piece of evidence of their learning with zero stakes attached to it.

Retrieval is probably something you already do, but to use it effectively we have to use it intentionally. I have two older blog posts about retrieval as a class activity and a study tool in my classroom with a few strategies. Personally, I always prefer to link up retrieval with some sort of additional strategy, whether its engaging students in discourse, having them compare and contrast or concept map.

Retrieval Might be the MOST important activity to support student assessments. Why? Because when students take an assessment they are asked to retrieve. However, if we are only ever pushing information during class, students rarely get the chance to practice that retrieval. Students should use retrieval to study, but they do not know or understand it typically, so we need to teach them (and their parents!) the benefits. If you’re saying “oh but I don’t lecture all hour, I have an active learning environment!” then I’m going to challenge you with this question: but do your students retrieve? Or are they only ever working in maintenance rehearsal? Relying on peers and notes to get to the answer?

My Favorite Use of Retrieval – Retrieve and Engage

Retrieval can be done as an act and of itself. However, while retrieval alone will enhance the memory pathways, it will not necessarily lead to a stronger application of that knowledge. In a science classroom we are constantly aiming for that higher order thinking: explain, create, evaluate. So we need to ensure that students are engaging in that thinking as often as possible.

The first way in which I enjoy using retrieval is by having students engage in a “brain dump”. Students write as much as they can about a given topic. To engage, students share their lists with classmates in small groups. We mix up the groups until eventually all students have the same information written on their papers. The 100% is in the room after all!

Another way in which I use retrieval is to ask students to complete a task identical to the previous day’s work, but then they pull out that work from their notes and evaluate themselves. The goal in this task, however, is for students to identify gaps. This task remains ungraded.

As I mentioned in a previous post, another way I like to use retrieval is to have students retrieve the content from the previous day, but then ask them to consider a similar, but slightly different case. In this instance students are first retrieving the example, and then are immediately asked to compare, contrast and then apply that knowledge to a new context. Below is an example activity that I used with AP Physics C students when going through simple harmonic motion derivations. We had already derived the simple and mass-spring pendula, so I asked students to retrieve those, then take a crack at the torsional and physical pendula.

Retrieval is not Endgame

While retrieval is an incredibly powerful tool that is easy to implement and we often forget to access, it is not endgame. It is simply one strategy amongst what should be an entire playbook. I see retrieval as a strong tool to motivate growth mindset and also as a strong tool to support teaching students how to properly study for the course and better identify their own gaps. However, especially in our science classrooms, it must continue to be paired with active learning cycles and opportunties for students to apply, create, do and evaluate.

ABCs of How We Learn: F is for Feedback

“Ever tried. Ever failed. No matter. Try again. Fail again. Fail better”

I’ve seen these words by Samuel Beckett on posters and in classrooms. The intention is to support the idea of the classroom as a safe space to try and fail. But failure without actional feedback is just failure. The classroom environment that has high expectations and high support is also an environment with ample opportunities for feedback.

Feedback can come in a lot of degrees, from a minimal “correct/incorrect” to highly detailed narrative regarding the student choices. For most of our students, the feedback they require should fall somewhere between specific discrepancy and elaborative.

Unfortunately many students are used to only getting feedback after a summative assessment, and without retakes any feedback is usually worthless. (Consider the student who crumples the test and throws it away immediately).

In order for feedback to be effective, it needs to be specific, timely, understandable, nonthreatening and revisable. (For the Hattie/Visible Learning enthusiasts, the weighted mean effect size is 0.92)

Teacher Led Peer Evaluations

A few years ago I started requiring homework submissions as scans to google classroom by the start of the school day. This allows me to do a quick skim through student work and make decisions for class prior to seeing students. Below is a sequence of student work I wanted to review and discuss with students.

Responses are left anonymous, but I use them as a way to provide feedback via whole group discussion. In this sequence you can see the work going from pretty disorganized to much more logical and detailed. I can lead this discussion, or I can ask for student observations about the work.

Student Self-Evaluations

I’ve written before about using self-evaluations for student problem solving process. I haven’t crafted these rubrics for every unit, but I’ve found that for some students this helps them focus on the problem solving routine, rather than just the answer.

Google Form Check Ups

The check up is a follow up I use when students are engaging in practice that is not scored, checked or graded by me the teacher. You can see the full blog post on this process here. During the last 10-15 minutes of class I have students engage in several activities in the google form. The first is a self-evaluation of the learning objectives. Sometimes I will ask them to rate their work from the problem set using a rubric I provide. Last, I will put 1-2 items from the day’s practice and ask students to explain the answer. An example from this past week is below:

After students submit their answer and click next, the following pops up. It provides them with the answer and an explanation behind it.

For what it’s worth, I was VERY impressed by the number of students who got a similar problem to this one correct on their exams this past week! Students are reporting that circuits has been the easiest unit yet, but the reality is that there is a great deal of conceptual heavy lifting!

One of the most important features of all of these feedback forms is that they are happening during the learning process. This means that students can very quickly adjust their course of action in order to move towards the desired results.
