One Student - Many Influences

Warming Up - A Short Suggestion
Here's another post based on things I've observed at the gym.
All exercise classes start with a warm-up. This is true whether it is a "thrive" pilates class, meant for senior citizens (which I learned after being 25 years younger than the average), or a butt-kicking spin class with Stacey A. When it comes to our bodies, it is understood that we cannot go from the street to the red zone without some transition time. Doing something easy for five minutes allows the following forty to be more efficient. Without the "sacrifice" of those first few minutes, we wouldn't be able to push our bodies to do more in the rest of the workout.
Do we understand that when it comes to our minds? Because of our limited class time, we sometimes expect students to dive into the deep end as soon as the bell rings, thinking we can't afford to "sacrifice" any of our valuable time. Perhaps, our students would benefit from the same kind of warm-up time for their brains that we would give their bodies. Starting class with a couple of basic recall questions related to the deeper thinking we want them to do would be helpful in making their thinking more efficient. By bringing the basic facts to the surface of their working memory, we might actually be able to push their analysis, synthesis, or evaluation abilities to do more in the remaining minutes of the class.
It's worth a try.

Working Out and Working Memory
I joined the YMCA about a month ago. While I know how obnoxious it is to talk about your workouts at the gym all of the time, I keep seeing things that align with education and cognitive science and can't help but make these connections. So, I'll try to do it sparingly, but you should expect that there will be more posts making the connections between fitness classes and academic classes.
The first thing to jump out at me at indoor cycling classes was the power of social norms, but I'll write about that some other time. The one that has struck me over and over again is the connection to working memory. For those that don't know, working memory is what you can hold in your conscious mind simultaneously, and for most of us, it is about four items.
I've taken spin classes from five or six different instructors, and while they all have a slightly different approach, one thing they all talk about is form. You get a better workout if you have your body positioned correctly and use your muscles in the correct way. But problems can arise when these instructions are delivered in a rapid-fire way. "Hands light on the handlebars, elbows bent, shoulders relaxed, abs tight, not hunched over, feet horizontal, legs moving in a smooth circle" is a lot to process at once. By the time I get to the direction of my feet, I've forgotten that my elbows are supposed to be bent. One day, this will all be one chunk in my mind, labeled "riding posture," but it isn't yet. A better approach might be for those teachers to focus on the legs and feet at the beginning and then wait until after the warm-up or after the first song to address your upper body. This might sound weird, but a poster on the wall with a picture of a rider in proper form or some basic reminders like "elbows bent, feet flat" could be useful as well.
Academic teachers, we can learn from this. When you deliver instructions, do you say a lot of them quickly? If so, it is unlikely that students remember the first or second step by the time you get to the last step. Better to give only a couple at a time, letting them get those down before you deliver the next ones. Or perhaps you could project the instructions, so they have something to refer back to when they have forgotten what comes next. For those who teach young kids who have not yet learned to read or English language novices, a picture of what you want (seated student with a pencil, a sheet of paper, and a calculator) would be helpful to their working memories. The picture is also easier to remember and doesn't require your presence or repetition the way verbal instructions do.
I have one instructor who described a working memory scenario without realizing it. She said, "Can you stay at 90 RPMs? Not go above it or below it but stay at it? Can you stay at the point where it is just hard but not your maximum? When you are at maximum work, you are less likely to quit, but when you get down to where you are working hard but don't have the mental distraction of all-out effort, you are more likely to quit." What she described as "the mental distraction of all-out effort" really means full working memory. When you are working right at the limit of cognitive load, you don't have the mental space to think about what it would take to quit or pay attention to the clock. When you have backed down to 85% of your maximum, you have freed up the space to wonder about how much longer you have.
This is instructive to academic teachers as well. Some people use cognitive load theory to assert that we should make things easier for students or reduce the rigor of our classes. That is not, however, what the theory implies. Understanding cognitive load and working memory should help us to identify the perfect level of load. There is a sweet spot where we keep our students working RIGHT AT or just below their maximum capacity. If we are too far below it, they have the space for their minds to wander and consider quitting because it is uncomfortable. If we are above it, they are incapable of sustained work, and they give up. Learning, at its best, is difficult but not impossible.
I'll talk more about working memory and cognitive load in the future, but for now, let's remember the lessons from working out and find the best ways to deliver instruction at the right level for our students to learn.

Explicit Expectations
Several years ago, Challenge Based Learning was a buzzword in educational circles. The idea is a nice one. Allow students to use their knowledge to solve a problem. And if that is how we all used it, I would be an enthusiastic supporter. Sadly, many teachers implemented it with a different philosophy - students don't need knowledge because they can look it up. So we started presenting students with challenges they couldn't solve because they didn't have the prerequisite knowledge. Their cognitive load was reached quickly, and the results were disastrous.
I do believe, however, that teaching kids problem-solving skills is a good idea and that applying knowledge to a problem they are capable of analyzing is valuable. So, rather than throw out CBL altogether, I have tweaked and modified a project over the years to achieve those goals while still working within the way their brains work.
I've written about my Global Solutions project in previous posts (part 2), and the project gets tweaked every year to make it just a bit better. The gist is this. I assign groups of students an area of the world that has significant problems that can be addressed with a knowledge of physics and engineering (By the way, this is the last project of the year; so they should have a fair amount of knowledge acquired). They are then assigned to study the resources of the area and propose a solution that is feasible, sustainable within the context of the area, and doesn't require government intervention.
Back when I was using the "rules" of CBL, I was extremely vague. The whole idea was that I shouldn't know what they would do. It was their challenge to solve. The problem is that no one operates well that way. Imagine going into a meeting at work and being told "solve a problem" with no parameters, no understanding of the obstacles, and no understanding of what your boss expects. You would be understandably frustrated and complain about your boss or ask him a million questions in an attempt to figure out what you were meant to do.
Does that mean we should abandon the entire idea of challenged-based learning? No. It means we should not follow the weird parts of it - the parts that were developed with the idea that a teacher should only be a facilitator, having no expectations or input. We can still have kids solve a problem, but we can also teach them the prerequisite knowledge first, provide them with clear success criteria, and discuss the pros and cons of their proposals.
This year in physics, I have a class that really likes to riff on silly things. (I'm sure you have never had a class like this, but they exist.). These boys throw out something like "Well, there would be less food insecurity if we took the Thanos approach." I remind them that our head of school and principal usually attend this forum and ask them to picture presenting the idea of killing half the population to them. I call this time "getting the bad ideas out of the way first." It is all well and good for one brainstorming session; I even find it quite entertaining. For a while. Two weeks ago, I was listening as the kids were talking (and I couldn't respond because I had laryngitis), and they were still throwing around silly ideas when we are too far into the project for that to be a good idea. So this week, I said, "Okay guys, it's been funny, but I'm not giving up class time for this anymore. Now, it is time to buckle down and look for real answers; I think some of you need to take another look at the instructions. Here's what I want you to have accomplished by the end of the period. You are going to fill out an exit ticket at the end of class, so you should probably look at the questions now." It was amazing the difference that made. They worked for almost the entire period, and they came up with ideas that can be developed into great presentations. They decided who would have each responsibility in the group. They accomplished more in that 40 minutes than they had during the entire run of the project thus far.
Free exploration works when a kid is interested in an idea and going from link to link without a plan in mind because there isn't a standard he is trying to meet or a timeline on which to accomplish a task. He's just learning what he wants to. But that is not the reality of classes or jobs. When it comes to those, it is important that we provide some clear expectations and either provide or expect them to create a timeline for their work. We need to give guidance and expertise, or they will not arrive at the place we want them to be; they'll wander around in a field. We could call it Guided Challenge or something that communities that we need to put them on the right road with a map.

A Tribute to GRACE Leadership
It's a weird time in education these days. Coming out of the pandemic, everyone is recovering from the chronic stress of the past two years. Students are less engaged. Parents are feeling insecure. Teachers and administrators are simply exhausted. This has led to some interesting outcomes. People are more demanding and less patient. Burned-out teachers are choosing other professions.
And, if you follow enough teachers on social media, you will find a lack of trust between teachers and their administrators. This may be the saddest impact of all. These are the people who should have each other's backs, but it seems that right now, people are too exhausted for empathy. As a result, many administrators don't give teachers the benefit of the doubt, and many teachers assume the worst motivations from their leaders.
GRACE isn't immune, but because we already had a close relationship with our leaders and were in awe of them through the remote and hybrid times, we have been able to hold on to our loving relationships better than most. As the year began, I prayed that this would be a year we would not have an opportunity to be in awe of their leadership. This week showed that this prayer won't be answered for at least another year. A teacher who has only been with us for a few months informed us the night before we returned from spring break that he would not be returning.
With only nine weeks of school remaining, what is a school to do with this situation? Try to hire a new teacher? With the amount of time that would take, students would be left teacherless for most of the remaining days of the year. As I said earlier, parents are feeling insecure about education as we emerge from the pandemic, and math is where that insecurity is most concentrated. I don't know what would have happened in other schools, but here's what happened at GRACE. Our principal stepped up and stepped in. She was a math and science teacher prior to entering administration, so our kids will learn math well for the next nine weeks. And, we know they will be loved for the next nine weeks.
But, it's not like she was loaded with free time before this happened. GRACE administrators have jobs that are more than full-time already. So, what happens with her principal responsibilities? Other administrators have stepped in. Our deans are doing more end-of-year planning, and our head of school is taking on more observations. Our librarian, who was planning the DC field trip with our principal is now bringing it home alone. The dominos just keep falling.
I don't know if shouting things from the rooftops was ever a real thing, but tribute must be paid to these awesome leaders, and this blog is the most public platform I have. Thank you, Mandy, for stepping up at a moment's notice for our students. Thank you, Meagan (our math department chair) for dealing with the inherent awkwardness this situation makes. Thank you to Eric, Blake, Daniel, Cathy, and Willa Bea for taking as much off Mandy's plate as possible in the coming weeks. Thank you to Marcia for making sure our 8th grade still gets a great trip to DC.
And, thank you to everyone who prays for us. Please add Mandy and the rest of these awesome administrators to your list if they aren't on it already. And, if they are, give them a few more minutes.

Open to Change
Like most teachers, when Wikipedia first started, I hated it. Students would sit in the computer lab, writing nonsense on pages, and the nonsense would stay for weeks or months. I warned students against using it and took points off if they did. Now, I have links to Wikipedia in my textbook, send students to it for some of my lessons, and donate to it every year. So, what changed? Well, Wikipedia changed for one, but I did too. As it became more used, the people at Wikipedia recognized their need for a better error detection system. They tightened up on who could contribute to their pages and created a system for flagging errors that was more efficient than they had once had. I also watched a TED talk by founder Jimmy Wales in which he describes their structure. He says something along the lines of "If you don't think our people care about accuracy, just remember that they volunteer to edit an encyclopedia in their free time." I thought that was a very good point, and it changed the way I viewed Wikipedia as well. (Listen, I'm not saying I let students use it for everything. It still isn't the place to do formal research for academic essays - although, depending on the topic, it can be a good place to find sources. But if you want to learn more about something as personal enrichment, it is often the best place to start.)
As a science teacher, I frequently use the phrase "our current best understanding" because that is what science is. For hundreds of years, our best understanding of gravity was Newtonian. Then, Einstein proposed some new ideas, and we think of it differently. Our understanding of the atom has experienced five major changes between Dalton and the Quantum model, but each time it changed, it was based on new evidence or a new observation of behavior. Most things aren't discovered all at once, so we must be open to change when new evidence is available. When I was a child, we were taught that the brain didn't change after you reached the age of ten (which I found confusing because we were at school), but we now know the brain is plastic and can be changed by learning and experience. While science is a search for answers, it can also be a search for the next question. It is all our current best understanding.
I would like to submit that we apply this to our understanding of people and situations as well. One of the best things about teaching 8th grade is that I have more chances to watch students change than most people get. A student that started unmotivated and misbehaved can become a great student by the end of the year. A new kid who begins the year socially awkward sometimes ends the year a leader. Since I also teach juniors and seniors, I have the privilege of writing college recommendation letters. Often, the theme of a letter is how much that student has changed since I first met them.
When we think of growth mindset, let's not just apply it to learning math or studying for tests. Let's recognize that experiences cause change in humans, and humans are having new experiences all of the time. Just like science and Wikipedia, be open to changing your opinion about people when you observe new evidence.
