Challenge Creator & the Desmos Classroom

Briefly

  • At Desmos, we’re now asking ourselves one question about everything we make: “Will this help teachers develop social and creative classrooms?” We’ve chosen those adjectives because they’re simultaneously qualities of effective learning and also interesting technology.
  • We’ve upgraded three activities (and many more to come) with our new Challenge Creator feature: Parabola Slalom, Laser Challenge, and Point Collector: Lines. Previously, students would only complete challenges we created. Now they’ll create challenges for each other.
  • The results from numerous classroom tests have been – I am not kidding you here – breathtaking. Near unanimous engagement. Interactions between students around mathematical ideas we haven’t seen in our activities before.

One question in edtech bothers us more than nearly any other:
Why are students so engaged by their tablets, phones, and laptops outside of class and so bored by them inside of class?
It’s the same device. But in one context, students are generally enthusiastic and focused. In the other, they’re often apathetic and distracted.

At Desmos, we notice that, outside of class, students use their devices in ways that are social and creative. They create all kinds of media – text messages, videos, photos, etc. – and they share that media with their peers via social networks.

You might think that comparison is unfair – that school could never stack up next to Instagram or Snapchat – but before we write it off, let’s ask ourselves, “How social and creative is math edtech?” What do students create and whom do they share those creations with?

In typical math edtech, students create number responses and multiple choice answers. And they typically share those creations with an algorithm, a few lines of code. In rarer cases, their teacher will see those creations, but more often the teacher will only see the grade the algorithm gave them.

For those reasons, we think that math edtech is generally anti-social and uncreative, which explains some of the apathy and distraction we see when students use technology inside of class.

Rather than write off the comparison to Instagram and Snapchat as unreasonable, it has motivated us to ask two more questions:
  1. How can we help students create mathematically in more diverse ways?
So we invite students to create parking lots, scale giants, mathematical arguments, tilings, sketches of relationships, laser configurations, drawings of polygons, tables, stacks of cards, Marbleslides, informal descriptions of mathematical abstractions, sequences of transformations, graphs of the world around them, and many more.
  1. How can we help teachers and students interact socially around those creations?
So we collect all of those creations on a teacher dashboard and we give teachers a toolkit and strategies to help them create conversations around those creations. It’s easier to ask your students, “How are these two sketches the same? How are they different?” when both sketches are right in front of you and you’re able to pause your class to direct their focus to that conversation.

Today, we’re releasing a new tool to help teachers develop social and creative math classrooms.

Challenge Creator

Previously in our activities, students would only complete challenges we created and answer questions we asked. With Challenge Creator, they create challenges for each other and ask each other questions.

We tried this in one of our first activities, Waterline, where, first, we asked students to create a graph based on three vases we gave them.

And then we asked them to create a vase themselves. If they could successfully graph the vase, it went into a gallery where other students would try to graph it also.

We began to see reports online of students’ impressive creativity and perseverance on that particular challenge. We started to suspect the following: that students care somewhat when they share their creations with an algorithm, and care somewhat more when they share their creations with their teacher.

But they care enormously when they share their creations with each other.

So we’ve added “Challenge Creators” to three more activities, and we now have the ability to add them to any activity in a matter of hours where it first took us a month.
In Parabola Slalom, we ask students to find equations of parabolas that slip in between the gates on a slalom course. And now we invite them to create slalom courses for each other. Those challenges can be as difficult as the authors want, but unless they can solve it, no one else will see it. In Laser Challenge, we ask students to solve reflection challenges that we created. And now we invite them to create reflection challenges for each other. In Point Collector, we ask students to use linear inequalities to capture blue points in the middle of a field of points. And now we invite them to create a field of points for each other.

We’ve tested each of these extensively with students. In those tests we saw:
  • Students calling out their successes to each other from across the room. “Javi, I got a perfect score on yours!”
  • Students calling out their frustrations to each other from across the room. “Cassie, how do you even do that?”
  • Students introducing themselves to each other through their challenges. “Who is Oscar?”
  • Students differentiating their work. “Let’s find an easy one. Oo – Jared’s.”
  • Students looking at solutions to challenges they’d already completed, and learning new mathematical techniques. “You can do that?!”
  • Students marveling at each others’ ingenuity. “Damn, Oscar. You hella smart.”
  • Proud creation. One student said, “We’re going to make our challenge as hard as possible,” to which his partner responded, “But we have to be able to solve it!”
  • Screams and high fives so enthusiastic you’d think we were paying them.
At the end of one test of Point Collector, we asked students, “What was your favorite part of the activity?” 25 out of 27 students said some version of “Solving other people’s challenges.”
I’m not saying what we saw was on the same level of enthusiasm and focus as Instagram or Snapchat.

But it wasn’t that far off, either.

Questions We Can Answer

How much does it cost?

As with everything else we make that’s free for you to use now, we will never charge you for it.

Will we be able to create our own Challenge Creators?

Eventually, yes. Currently, the Triple C (Challenge Creator Creator, obv.) has too many rough edges to release widely. Once those edges are sanded down, we’ll release it. We don’t have a timeline for that work, but just as we think student work is at its best when it’s social and creative, we think teacher work is at its best under those exact same conditions. We want to give teachers the best toolkit possible and enable them to share their creations with each other.

Questions We Can’t Answer

What effect does asking a student to create a challenge have on her learning and her interest in learning?

What sorts of challenges are most effective? Is this approach just as effective for arithmetic expressions as laser challenges?

Does posing your own problem help you understand the limits of a concept better than if you only complete someone else’s problems?

Researchers, grad students, or any other parties interested in those same questions: please get in touch.

Friday Fave for October 27

The snow has begun to fly in the land of the Friday Fave. A bit early perhaps, but it was due sooner or later. Plus, there’s an upside. Frozen water means less friction, which puts the Friday Fave in the mood for a good slalom.

If your precipitation isn’t frozen, or your skis are inaccessible, or the absolute values of the slopes in your nearby terrain are all too close to zero, then you’ll need to keep your slaloms electronic. Fortunately, the Friday Fave is here to help with that!

The Fave presents Parabola Slalom. Send a parabola through a series of gates. Any parabola that works counts, and creativity is encouraged.

As usual, things begin informally. Transform the parabola by moving some points around.

Soon, things become more formal. You have to define your parabola symbolically.

Eventually, we’re asking you to design your own slaloms. Can you design one that cannot be solved?

Simple entry to meaningful and challenging tasks. That’s what makes Parabola Slalom this week’s Friday Fave.

While you’re thinking about parabolas, maybe check out the following additional parabola-related activities.

Friday Fave for October 13

There are times when we all just need to set our troubles aside and have a little fun.

At Desmos, that usually means math-based play, and if you’re the kind of person who’s into this kind of thing, the Friday Fave invites you to join the club.

While you will be playing golf in this week’s Fave, you will not need clubs. No, you’ll need to sink those putts with rotations, reflections, and translations in Transformation Golf: Rigid Motions.

You’ll find some of our challenges simple, and some of them quite difficult. Keep in mind that this all about fun. No one’s keeping score. Take all the mulligans you need.

Sure, the Fave could tell you about the Common Core standards that introduce congruence by way of rigid motions. Or about the importance of developing spatial visualization skills, or even about how breaking things down into discrete steps can support learner’s development of algorithmic thinking. And that’s all true! But sometimes you just want to play.

In that spirit, here’s a class code: TV67R.

Then when you’ve finished on the course for the day, check out these other activities on the Desmos math playground.
