Panera Bread and Learning

In the last month I’ve become a Panera regular. We’ve been doing a lot of traveling and Panera was as close to fast food as we were willing to go. Until the last month however I’d only been there a few times in several years, without being particularly impressed.

Take a look at the menu above. This is what you encounter when you walk into Panera Bread for the first time. Seven sections of menu packed with different dining options. For the less food savvy among us, not only is the menu packed with stuff, but it’s packed with a lot of stuff that is unfamiliar. In my first couple of visits I stood there bewildered for a while, let my friend order, then picked something with turkey in it.

Because I was pretty sure I knew what turkey was.

Well, I was wrong. I mean, I think the thing had turkey in it. But everything else did not complement the turkey in a positive way.

The next time I went there with a few colleagues I ordered a caesar salad. Why? Because every time I’ve ever ordered a caesar salad in a restaurant I haven’t been surprised by what came out. The same was true for this visit.

Sweet. I found something on the menu without holding up the four people behind me.But after that I avoided Panera for a while. A long while. I could get a caesar salad from a lot of places. The notion of standing there in line trying to find something different felt as though it would only bring frustration.

Then my wife and I were looking for something quick and healthy to eat, so we decided, to my slight dismay, to give it another try.

This time however, on the way there my wife looked up the menu on her phone and read off several items, describing them from their website. When we walked in I knew several of the items on the menu, how it worked (that “pick 2” thing for example) and was basically ready to order when I walked up. We’ve been there a couple of times since and now it’s one of my favorite restaurants. Since I’m confident in my understanding of the menu, I try new items, ask questions about different types of food, etc.

How does this relate to learning?

Think about the first time you encountered an unfamiliar topic and tried to learn it. This was difficult at first but I can certainly think back to math lectures (here’s lookin’ at you, Linear Algebra) in which there was new notation, vocabulary, and concepts and it all felt unfamiliar.

However, once I got with my peers and we began working through the problems (encountering the “menu” multiple times) the concepts began to feel more familiar. I realized that I knew more about them than what I thought (romaine and kale! Hey, I know what those are…). The more I worked individually and with my peers the clearer the concepts became.

If I avoided doing the exercises or only did it individually, that feeling of everything being foreign never really went away. Usually parts of the notation would be confusing. Or the instructions around a problem wouldn’t make sense. Or I could start a problem, but get lost in trying to solve it, etc.

A couple points can be pulled from this. First, a student’s first exposure to a topic is incredibly important. If you drop seven new vocab words and a gaggle of new notation on students at 8:00am on Monday morning you’re bound have a large group of students not wanting to come back to the menu you just presented them.

Even if they should know most of the food on there.

So we have to think carefully about how students first engage with content. The second point is helping students understand that multiple engagements with a concept will (usually) alleviate this feeling. I think many students never go back to the restaurant because they don’t want to be embarrassed for not knowing what their peers may already know. We have to help students be comfortable with this phase of unfamiliarity (my study group in college was a place I felt comfortable being wrong), and develop tasks that help them engage with the concept in safe, productive ways (investigating the menu on the way).

Math, Play, and a bit of Desmos Love

I’m sure a lot has been written about how Desmos is an incredibly valuable tool for the math classroom. I’d like to echo those sentiments and give a few observations from my classroom related to Desmos and play in mathematics.

My thoughts for this post stem from this activity. It’s pretty math heavy but the basic idea is that students spend time making conjectures and either verifying or invalidating them. When their conjecture is invalidated, they spend time tweaking their functions in Desmos to match the actual answer. These kinds of activities are becoming commonplace in my classroom and I’ve noticed a few positive shifts in my classroom environment. First, engagement has increased. I had a couple more high fives during this activity (and a bunch more in a previous activity) and 100% engagement in class. To be fair, this is AP calculus so it is the “better” students, but I am hard pressed to find 100% engagement when I give p. 102 #1-15 from the textbook. Second, they learn better! This shouldn’t be a big surprise since we know that allowing students to explore/play with a concept before direct instruction often yields better results (See page 58 of this research and this learning model from Ramsey Musallam if you don’t believe me). My students came up with these definitions of the chain rule without me ever saying the term “chain rule”, giving any direct instruction on the chain rule, and with minimal guidance from me. Don’t get me wrong, we followed it with a formal lesson on the chain rule with several examples and they will have an assignment from the book tomorrow, but I think laying the groundwork with the activity will pay dividends later. There’s also another pay off here…

Students are more motivated to come to class. They enjoy activities in which they are allowed to, if you can believe this, play with math. I don’t think this is possible without Desmos. The power in it is that it breaks down barriers for students. It’s like giving a student a canvas, paint, and brushes and saying “here, work with this for a while, make some conjectures, tinker with it, and tell me what you come up with at the end. ” Maybe I’ve drank a bit too much of the Lockhart cool-aid, but to me this is the essence of mathematics. I don’t agree with all of Lockhart’s points, but I think the link between curiosity, play, and learning is powerful and we can leverage that linkage in ways that create powerful learning experiences.

And if I haven’t convinced you yet, check out this excerpt from one of my student’s blog posts below.

“Writing this statement in question #4 required that I fully understood what was being shown in the lab. It made me think deeper about how I came to that conclusion. I believe that looking at the graphs, analyzing relationships between them, and forming a conjecture in my own words helped me to truly learn and understand the concept rather than just being given the relationships and rules and being asked to memorize them.  By completing this lab, I have improved in my ability to  identify what the graph of a function’s derivative should look like. I feel that I have a much better understanding of the relationship between functions and their derivatives and I know that I can look back at the examples in Lab 6 if I ever need help.”

I’d love to hear your thoughts on this. What are your experiences with learning and play? How does it fit into your content area or your classroom?
