Connecting Math and CS with probability game simulations

One of my goals for this school year was to build out a few interesting and relevant projects into the 7th grade curriculum, which seemed a bit dry and skill-focused. One area that seemed to beg for an application project was the first unit on Data and Probability. Since one of my other goals was to incorporate more computer science into my classes, it was a no brainer. Developing a cross-over computer science project for this grade level proved to be a bit tricky because students are all over in terms of their experience with programming - we have students who have been coding for years as well as new students who have never coded anything before. I tried to develop a project that would differentiate appropriately and allow students to either explore the CS or the Math parts in greater depth, depending on their interest in and experience with programming.

Here is the project description. You'll notice that I created three distinct strands with different goals and let students select the one that was most appropriate and interesting for them. I was also lucky that the computer science teacher was able to come to my classes for some of the time that students worked on this project. Having many intermediate checkpoints for students to submit pieces of the project was very helpful here in ensuring that I could identify those who were behind or struggling and work with them during class.

Things that I would still like to build out:

• A more robust peer editing process -- I'd like students to be able to present their optimal winning strategy to peers and get critical feedback on how convincing their reasoning is that they would be able to incorporate into their final draft
• A revised rubric to make it more concise
• Move some pieces of this project out to computer science class - this definitely took up quite a bit of time, especially because I felt that most or all of the coding work should happen during class where students would have support
• A clearer division between group and individual aspects - this is always a challenge for me when designing group projects in terms of maximizing student learning and individual accountability. Students seemed to work well together during class, but this isn't an explicit part of the project currently. 
• Some sort of final presentation - for projects like this, I think that having the final product on display or presented to others creates a much more authentic need for clarity and functionality. I haven't figured out a good way to do that for this project. Should students do a gallery walk of projects within the class? Can this be presented or shared with students in other classes somehow? What about with parents?
• Other connections - is this something that can connect to students' work from previous years so that it feels less like a stand-alone project and more like a continuation of ongoing work and thinking? Are there other aspects of this project that can connect to other disciplines, like writing? Can we build on this in future years of either computer science or math curriculum?

Reflections

My school is committed to having students reflect on their learning, both in terms of math-specific development and student habits*. The research is pretty strong that reflecting on learning is a huge component of solidifying understanding. As John Dewey wrote, “We do not learn from experience... we learn from reflecting on experience.” Reflection as a skill is something that we intentionally cultivate and assess, but I am always working on making it a more integrated component of my classes and something that students value and appreciate.


Here are some ways that I've worked on doing this over the past few years:

Start of year reflections: establishing relational aspects of class and setting goals

We spend the first two weeks of each course working on open problems and having students read, watch, and discuss ideas that we think are important to setting the tone for the year, establishing classroom norms, and getting buy-in for learning through problem-solving

• Students respond to readings about mathematical practices and/or habits of mind:
• Reflection questions on first chapter of Make It Stick
• Reflection questions on "How to Learn Math" video from Youcubed and excerpt from Mathematical Mindsets
• Math autobiography
• Students reflect on their history as students and mathematicians and set goals for their work in this class

Reflections that emphasize content: after each lesson/assignment and after taking an assessment in order to correct course

We want students actively thinking about their progress in the course, returning to their goals, reflecting on their learning, and fine-tuning strategies in order to make progress.

• At the start of most classes, students summarize the main topics from the last class and homework assignment and reflect on their understanding through this Desmos Activity Builder.
• After most assessments, students reflect on their work in the class, both in terms of content learned and the development of their mathematical practices and student habits
• Typical post-assessment reflection; We realized that having students reflect on ALL mathematical practices was a bit much for a single reflection and tried to pull out a specific practice to reflect on  
• Correct and reflect on errors; plan what to do next

Reflections that emphasize practices and habits of learning: projects, homework, note-taking

• Students reflect on their learning and process on all projects and investigations 
• Menu of write-up reflection options (scroll to the bottom)
• Not strictly reflection, but we are starting to use peer feedback to have students develop specific mathematical practices
• Peer feedback on homework
• Reflection on note-taking
• Peer feedback on note-taking

Things I still need to work on/think about

The reflections were mostly created based on perceived need and don't necessarily spiral and build on each other as clearly as they could. I'd love to spend time going through the prompts and making them more specific - thinking about which mathematical practices should be cultivated at the start of the year, which ones later on, and which ones should be spiraled back to at later times. This would also help make the reflections shorter and more specific, encouraging deeper and more thorough responses. 

I'd love to hear about others' experiences with reflections so please comment or tweet at me with questions or feedback.

Getting students to dig deeper into rich problems

So I was going to participate in the #MTBoS Challenges, but then, life happened. I did write a blog post responding to the first challenge, and even though I'm not participating in the full scope of challenges, I'd like to post what I can. So here is what I wrote in response to the question "What is one of your favorite open-ended/rich problems?  How do you use it in your classroom?"

Even though we were directed to write about a favorite rich problem, I’m going to write about a problem that is the most recent one that I’ve done with a class because I’m having some issues with the way it’s worked out and would love some feedback on how to make it better.

The problem that I recently gave my 2-year Algebra students (these are 8^th graders in the second year of a 2-year course that covers a standard Algebra 1 curriculum) was the first one in the Integrated Math Program, Year 1 book, called Broken Eggs. This was students’ first problem of the week, in which they are to write up their problem-solving process and justify their thinking and solution, if they find one. In this problem, you are told that a number of eggs when put into groups of 2, 3, 4, 5, or 6 always had one egg left over, but fit perfectly into groups of 7. Students were asked to determine whether there was only one unique solution or whether there were many possible solutions, and if so, how they were connected to each other.

Full problem:

Broken Eggs POW by Anna

I gave students 20 minutes in class to start working on the problem (5 minutes alone, then 15 minutes with their group members) and a week and a half to complete their write-ups. I also met with students individually who were struggling.

I thought that the problem was a good one with which to start as it could be approached from a variety of angles and would encourage for the looking of patterns. However, the results were pretty disappointing. Most kids were only able to find the first solution and did so using brute force (writing out the multiples of seven and testing each one to see how it divided by 2, 3, 4, 5, and 6). Quite a few kids just looked at numbers that weren’t evenly divisible rather than looking for a specific remainder. Almost no one found any other solutions and not a single student found a pattern between the solutions. Almost no students even attempted to find one. So the problem just turned into one that required some organization to keep track of things, but almost no algebraic thinking. So basically, the result was a lot of annoying calculations with little payoff.

I am trying to think about what I could have done differently to encourage students to keep going and to notice patterns that would make their work easier. Having students share strategies maybe would have helped to disseminate some of the shortcuts that a few of the students discovered, but not ones that no one figured out. I think that part of the tension for me is that I want open problems to really be about students’ thinking and approaches, but also be a learning opportunity that stretches them past their current abilities and into something more advanced, and I don’t know how to do that without giving hints or telling kids to change their approach. Basically, I want them to learn and be stretched mathematically, but have it be organic and come as an extension of their own thinking rather than a top-down approach where I direct them.

Part of the issue also is that kids are mostly to work on problems of the week outside of class so I’m not getting much of a chance to see their thinking before they turn them in to me. So another change that I’m thinking of doing is having students turn in a “rough draft” that I can give them feedback on or that we can confer about in person before they complete their write-up. There is a thin line between pushing a student’s thinking and directing it onto a predetermined path that takes away from the problem’s openness and richness, and I am still navigating how to do this in an optimal way. Suggestions welcome!

Writing and reflection

One of the goals that I set for myself this year was to make writing a more regular part of my class, rather than the add-on journal entries I've had students write the past few years. Kids had been resistant to these (a few refused to do them at all) and I felt like I wasn't seeing much improvement as the year went on. Those who were reflective and took the assignments seriously got something out of it, but lots of kids did a crappy job, took a 1/3 or 2/3 score and moved on with their lives.

So this year, I started the first real unit (after reviewing last year's Algebra 1A material) with worksheets that kids started on in class and that had more problems and a reflection piece at the end for them to complete at home. Here's one (adapted very closely from CME Project Algebra):

Ch. 7 Day 1 12-13

I used the same writing prompt each day:

How well did you understand today’s lesson? Use one or more of the following prompts to help you answer this question (write at least a few sentences, include at least one example).

a. One thing that I understand really well from this lesson is…

b. One thing that I didn’t understand at first from this lesson, but now do understand is...

c. One thing that is still confusing to me from this lesson is...

d. Something that I’m wondering about that is related to this lesson is…

Some positives: 

• Every kid is responding to these. Maybe because it's the last question on the assignment and they've already put in all the rest of the work, or because it is an almost daily component of their work and thus normalized, but I'm having much less resistance to writing this year.
• I feel like I'm getting a better understanding of kids' misconceptions and questions. Yes, there are some who always say "I understand everything. Here's a trivial example." But lots of kids are taking the time to write about a problem type they don't understand or a question they have about the topic that wasn't addressed in class. 

Things that still need to be worked out:

• Getting kids to use the example as evidence for what they are saying in words. I want the response to be a coherent piece of writing with the math embedded in the words, not as an add-on because it's a requirement to include an example. 
• Having kids go deeper in their explanations, rather than just stating a procedure they used (or not explaining what they did at all). I want them to explain why their approach worked (if they're using prompts a and b) or where they got stuck (for prompt c). I would also like them to write more. I think that if I require at least a paragraph minimum, fewer kids (ahem, boys) would be tempted to just pick the easiest example from the notes and try to regurgitate it back to me in the fewest number of words possible.

Here's one of the better ones from last week because this student actually explained their example in detail. Again, I'd like them to go a bit deeper into the "why," but at this point in the year, I'll take it.

So, a few things that I know I need to do to promote better writing:

• Give specific feedback. I've been saying things like, "needs to be longer" or "explain your example," but I should really talk to kids and tell them more specifically what I want them to change.
• Show examples of strong math writing and have kids point out what the person has done well, in addition to things that they can still improve on. 
• Tell kids why it is that I'm having them do math writing. Perhaps it would be helpful to (in general terms) talk about the research on metacognition and learning. 
• Change up the writing prompts and have more writing responses to actual math problems. I just had kids do an investigation in class with the homework assignment being a writeup of the problem, their process, and solution, if any. Once I grade these, I will have a better sense of where they are at with their writing about math and where to go from here.

Any other suggestions??
