Physics, a helicopter and cameras

First watch this (and be amazed… well, if you’re anything like I am.)

So, when the students can get past the idea that there is some foul play involved, then it becomes a wonderful opportunities to discuss the idea of frequency.

Frequency is an odd discussion because it’s got a strange unit. The “per time” can be a little challenging for students to wrap their heads around.

And the opportunity that this video provides is that here, we don’t need to immediately concern ourselves with the quantitative value of the frequency (maybe 300 RPM for the helicopter rotor, for example, or 5 frames per second on the camera), but we can begin with the qualitative value of the frequency (that the frequencies, whatever they are, are the same.)

And then it opens the door for them discussing some quantitative issues. For example, the fact that the standard unit of frequency (the “per unit time”), obviously isn’t constant. So, the helicopter rotor is RPM and the camera shudder is typically in frames per second (at least, I think. Not a photographer…) So, you’ve got some nice dimensional analysis opportunities.

Where could you take this next?

One thing’s for sure, I’d hate to waste a video like this. Fully captivating, and it only costs your 30 seconds of class time.

Perplexity and how it appears…

Here’s a video (by Derek Alexander Muller) I think you should watch.

 

The critique of #flipclass aside, I’m intrigued by the way the narrator describes the value of “bringing up the misconception”. It’s almost like a thorn that creates some discomfort that only learning will relieve. This gets close to Dan Meyer’s use of the word “perplexity”.

From Dr. Meyer: “Perplexity comes along once in a while. What is it? It’s when a kid doesn’t know something, wants to know that thing, and believes that knowing that thing is within her power. That right there is some of the most powerful learning moments I’ve ever seen – so powerful that it’s really hard for me as a teacher to mess those up.”

There’s power in perplexity. I’ve seen this in my classroom on multiple occasions. It’s important to remember that there’s three distinct parts to creating what Dr. Meyer is describing. First, there needs to be something worth knowing. Second, you have to create the want. And finally, we need to empower the students so they feel enabled to know that thing. What Dr. Alexander suggests is that becoming aware of your misconception seems unsettling (leading to claims that videos were confusing), but also leads to more learning. The discomfort fed a drive to resolve the discomfort.

The tricky thing is that misconceptions are a tool you can use when they are available. Science provides a particularly fertile ground for misconceptions because so much of it is drawn from experiences many of us have regularly. Alexander uses the model of a ball flying through the air. This video uses the phases of the moon and the seasons.

The potential for misconceptions is necessarily lightened when there’s no misconceptions, so the quest for perplexity in math needs to take on a different look, proper planning and timing, and different strategies for when perplexity isn’t an available option. (Preconceived notions are just as good at times. After all, we ALL think we know something about squares!)

It’s like Dr. Meyer says, those wonderful perplexing moments only come along once in a while. We foster those moments when we have them, try to create as many as we can and we do our best every other time.

 

A year’s worth of questions

For the past two semesters, I’ve been in lots of mid-Michigan classrooms. As I observed teachers teach, I wrote down my questions. I wrote them down in a little black book that fit in my back pocket.

The questions serve for good reflection. They have more to do with my developing understanding than they do the teachers’ performances. That isn’t to say that sometimes I didn’t see stuff that needed to be fixed up. I did. But these questions were often meant to guide my own thinking.

Here are some of the questions I asked and the observations I made.

“How do we sell screeners?”

“What’s the role of balance?”

“Do you believe in growth mindset? It should follow then that something is true that doesn’t currently make sense to you. Probably more than one. Who do you trust to give you that growth?”

“How do you download the interactive whiteboard lesson?”

“Seems like students with speech disabilities might struggle with “stretch out the word.”

“What are the expectations with iPads?”

“Could students fill out an online form instead?”

“How could we up the engagement?”

“Don’t say this: ‘I need to pull up my rubric so I can grade you’. Say instead: ‘I want to document the different pieces of your presentation.’ ”

“Presentations are tough. That was largely wasted time. How to do better?”

“They aren’t sure what to do. And they are having a hard time staying in their seats.”

“It’s loud, but to be fair, the center activities are somewhat loud… and the parent volunteer isn’t managing the volume at all.”

“Teachers who are trying to recover their classroom management will become cold… tough… no-nonsense. Does that help?”

“What if you think-pair-share…? This is too rich an activity to only have a handful of confirmed engagements.”

“What about those four kids in the back?”

“Teacher seemed to feel her control slipping, so she went heavily to individual. Calling on kids as a control piece.”

“Big question: What is the learning target of this lesson?”

” ‘I’m going to let Mikayla have some think time here.’ What if they were all solving the problem while Mikayla was thinking?”

“What is the group’s cue that they should talk?”

“Blurting out is a problem because so many want to participate. Could they?”

“It included this beautiful moment when the teacher actually said, “Gimme fiv… oh.” and was surprised when the kids were all on task.”

“Teacher never raises her voice… on the contrary, when a kid needs more attention, she seems to get quieter.”

“Big issue here is that the students aren’t responding.”

Growth Mindset – It’s not that simple

I am often not on the intellectual cutting edge. Pretty much any idea that I’ve had, someone else has had before. Usually lots of people, actually.

This discussion of growth mindset is no different. The Atlantic (specifically Christine Gross-Loh) and the Harvard Business Review (written by Growth Mindset author Carol Dweck) beat me to this one. And that’s okay. They have folks whose job it is to write. I do this as a hobby. I’m just grateful for their shoulders to stand on.

Growth Mindset is becoming a fad. Of course, Dr. Carol Dweck (who is responsible for coining the term and the supporting research) understands this better than anyone. What will happen to the term “growth mindset” when it gets unleashed on the public and Twitter gets a hold of it?

Well, certainly the nuance is gone. The public arena (and it’s right arm: social media) tends to treat nuanced arguments like they belong on a dollar-store clearance rack. So, at the very least, you can count on growth mindset being over-simplified (probably quite significantly at that).

With over simplification comes the inevitable misunderstanding. If all you know about this idea a series of talking points laid out 140-characters at a time, the chances of you missing an essential component are quite good. Of course accidental misunderstanding is independent to one’s confidence to propagate their (mis)understandings on the topic.

And of course, researchers have a love-hate relationship with this phenomena. On one hand, they are getting often getting criticized for statements made by people who don’t really understand the actual point they are making. Not fair, but common. (Ask our Lord Jesus Christ, Charles Darwin, Martin Luther…).

On the other hand, your idea becoming a household-familiar is evidence of success. The constant (though flawed) propagation of your idea means you’ve created something that’s resonated with the masses. (Or, as Chamillionare said, “Weird Al isn’t going to do a parody of your song if you’re not doing it big.”)

And of course, this explains why growth mindset is talked about with such a wide range of implications. Sometimes, it takes more than Yoda and Darth Vader posters to explain complex topics… particularly topics wrapped around the way an individual sees the world around them.

Says Dweck (in The Atlantic article), “Many people understood growth mindset deeply and implemented it in a very sophisticated and effective way. However, there were many others who understood it in a way that wasn’t quite accurate, or distilled it down to something that wasn’t quite effective, or assimilated it into something they already knew.”

As with most things, in order to experience the full benefit, there needs to be fidelity with the implementation. Otherwise, what gets left out might be the thing that makes it effective.

From The Atlantic article:

But Dweck recently noticed a trend: a widespread embrace of what she refers to as “false growth mindset”—a misunderstanding of the idea’s core message. Growth mindset’s popularity was leading some educators to believe that it was simpler than it was, that it was only about putting forth effort or that a teacher could foster growth mindset merely by telling kids to try hard. A teacher might applaud a child for making an effort on a science test even if he’d failed it, for instance, believing that doing so would promote growth mindset in that student regardless of the outcome.

Or as Dweck says later in the piece:

another misunderstanding [of growth mindset] that might apply to lower-achieving children is the oversimplification of growth mindset into just [being about] effort. Teachers were just praising effort that was not effective, saying “Wow, you tried really hard!” But students know that if they didn’t make progress and you’re praising them, it’s a consolation prize. They also know you think they can’t do any better.

So, there’s a little more to fostering Growth Mindset than “praise the effort, not the outcome.” A lot more, it turns out. From Dweck’s article in Harvard Business Review:

“Even if we correct these misconceptions, it’s still not easy to attain a growth mindset. One reason why is we all have our own fixed-mindset triggers. When we face challenges, receive criticism, or fare poorly compared with others, we can easily fall into insecurity or defensiveness, a response that inhibits growth. Our work environments, too, can be full of fixed-mindset triggers.”

It involves really understanding our own inner balance of fixed and growth mindsets. Growth mindset isn’t the easiest way. It’s the most valuable way. Are you sure you really want a growth mindset? Remember, thinking you’ve maxed out your ability provides a neat little excuse to only “do your best” as opposed to what WMU football coach PJ Fleck regularly calls “changing your best.” And even if you are convinced in the value of growth mindset, you still have to convince your students.

Dweck beat me to that one, too. From the Atlantic article:

Finally we talked about why someone would want a growth mindset. We realized that some kids would be overjoyed to hear you can develop your intellectual abilities, but others might not think it was the most exciting thing. So we then had a whole section on why you might want to develop your mind. Teenagers are really excited about the idea that they can do something to make the world a better place. So we asked them what they want to make their contribution to in the future—family, community, or societal problems—and then talked about how having a strong mind could help them make their future contribution.

Nestled deep within growth mindset is “growth”. Growth toward what? Well, certainly away from what we currently are (because it’s not good enough yet) toward something else (presumably something better.) This mindset is fundamentally at odds with a philosophy that says, “Don’t worry. You’re perfect just the way you are.” If that were true, why would we need growth? Why are we trying like crazy to help our students “grow”? Why should we be trying like crazy to model that in ourselves?

Certainly because we’re not all “perfect just the way we are.” In fact, in a time of struggle, it might be more helpful to be told, “perfect or not, you’re not stuck the way you are. You can be more. I’ll help you. And if you try for it, your effort will be rewarded.” That’s what growth  mindset brings to the table.

So, how do you operationalize that? We’ll have to save that for another post. (Although, as usual, I’d love to hear your thoughts.)

 

Investigating the shadow

I relearned an important lesson about students today. And, as is often the case, the lesson was learned while visiting church. But, it wasn’t the priest who taught me the lesson. Not the deacon, not a Bible study leader… not even a human.

It was a candle that illumined me.

See, in our church, there’s candles. Candles do a variety of different things. The most obvious of these is they produce light. But this isn’t all they do. See?

img_20161129_190036795

Actually, maybe you don’t see. I mean, when you are used to looking at candles like this, then the light is probably the most obvious effect. I suspect if you are close enough to it, you will quick recognize the heat as well.

But those candles are doing more than that. (I’m not trying to get all spiritual on you here. I’m talking physically.)

Can you see it? Maybe you need another picture of the candles.

img_20161129_190051749

So, this is the same set of candles, but see? I took a picture of the shadow the candles cast on a nearby wall. See the distorted image vertically rising from the candles? There’s something happening to the light that passes through the space directly above the flames that messes with the light as it passes through.

But you can’t see it here. I mean, I guess maybe if you stare at it long enough… maybe…

img_20161129_190036795

Anyway…

By now, it would be reasonable to ask why I was so interested in candles. And the simplest answer is that I saw something that intrigued me.

Is this the way it is with our students? There are lot of things they are doing that are obvious. They are loud or quiet. They are successful or struggling. They are social or reclusive. These things are obvious. These are the flame of the candle. Any teacher paying any attention to their students would see these things.

But what we don’t see are the hidden effects.

We don’t see that the successful student is working like crazy because of the pressure her parents are putting on her. (It’s not work ethic… it’s fear. Be prepared for what that looks like when the struggles come.) We may not see that that student who is struggling is a skilled leader on her soccer team. (There’s a lot of usable strengths if you can just create classroom situations that use them.) We don’t see that the student who we don’t think is paying attention could design and implement not less than 3 effective fixes for that wobbly stool in your classroom. (How can you sell your content on that student?)

To successfully support these students, we need to see their shadow along with their light.

How do you look at your students differently? There’s a variety of different ways, but the first is that you need to be interested. You need to be willing to see something that intrigues you. Find ways to see them differently. In general, school mostly expects students to do the same sorts of things. But you don’t HAVE to do it that way. Challenge the successful student. Innovate with the struggling student. Chat with the quiet student.

Remember that their “shadow” would almost certainly reveal plenty of things going on. Important actions, skills, impacts that you aren’t aware of. How would the classroom experience improve, both for the student and for you, if you knew what those “shadow” effects were?
