Cat Chase

Play the game!

I've been filling up the blog with my class notes from Learning Creative Learning, but an assignment from there really turned into a fun project.

In Week 6 we were supposed to remix Scratch projects from other users. I - of course - looked for math games. First I found 15 Seconds by jOHEEN_c which was an integer game. I wanted more leveling, so found Maze Levels 1-5 by Cats_Are_Awesome. I didn't wind up using their code, but I did learn a lot about Scratch by working through their programs.

I wanted the levels because increasing challenge is key to engagement. I have about 10 screens of increase, after which it levels out. The movement is a little challenging for me as an old guy: the cat follows the mouse instead of being controlled directly. The game forces you to add and subtract positive and negative, but gives you choices on how to get the target. I did add a restart button for if you got stuck that lets you proceed without having to play all the levels over. Is it a problem that the game never really forces an end by becoming impossible?

The game is on the Scratch website, where you can play it or download the code. (Scratch is free to download, of course.) All Scratch submissions are cc 3.0, which is very nice. (Direct link to video, made with Screenr.com.)
(You can embed the Scratch program directly in a webpage, but it starts immediately, which can be aggravating.)  I would be very interested in your feedback on the game, and delighted if you or your students would be interested in remixing it.

Interest-based Learning & Constructionism

Creative Learning - Weeks 2 and 3
Huh? What? No - I didn't fall asleep in class. We took a family trip! (I.e. look for a vacation math post soon.)

One of the many things to catch up on is the Creative Learning Class. (See Week 1.) Phil Aldridge has been a better student - maybe you should copy his notes, instead.

Week 2 was a video session with Joi and Mimi Ito on interest based learning, main reading the Foreword to Papert's Mindstorms, and the Macarthur Foundation Connected Learning report. More resources linked from the course syllabus.

Video Notes: The Itos talk about informal education. Interestingly a lot of former physics majors who lost interest when teachers couldn't explain things intuitively and relied on formalism and symbolic manipulation. They want education to be motivated, and recognize that learning can be motivated by interest and relevance, but attention to diversity is important. Don't feel like they addressed well the questions about how do you deal with less productive interests and time scale (can't learn-on-demand the night before a recital). Important point: have to have a broad range of acceptable work and kinds of recognition. Broader mission, learning, social networking, traditional rewards. (Again the gamer types.) Joi:"The whole idea of higher ed... is that you need a standardized degree ... so it's all about individual standardized skills." Beware curricularization of all of student interests. Mimi cited Katie Salen's schools that have boss levels after the standards required units. Since academia is geared to formal, structured thinking, those are the learners that flourish. It just doesn't motivate a lot of kids.

Assignment: Read Seymour Papert’s essay on the “Gears of My Childhood” and write about an object from your childhood that interested and influenced you (and share with your group). Also try the Marshmallow Challenge. (Done that, never wrote it up. Dave has a nice piece on it, though.)

Haven't seen too much activity from my group yet.

It was a straight line kind of building and play.
 I was really fortunate to have so many building tools/toys. I'm old enough that video games weren't dominating, but a curiosity. Mattel handheld football was the star, unbelievably. Sometime later Intellivision, but that was more my younger brother's speed. Erector set, Lincoln logs, and, ultimately, LEGO.

Really any robot, really,
though Zeroids and Robot were my faves.
Thinking about it, though, my play was always story motivated: the things I was building were for Micronauts, early action figures and any kind of robot. To some extent it's the same now, where teaching becomes the story that lets me build the things that are fun to build and play with. (Games, GeoGebra, cool math ideas and relationships, etc.) Looking back at these things was suprisingly emotional and I still have strong connections to them.

Recommendation: read Papert.

Week 3 video chat with Leah Buechley, Dale Dougherty (Maker movement) on Constructionism (not -ivism but -ionism), read Papert Mindstorms chapter 1 and The Children's Machine chapter 7 (on instructionism vs constructionism). Also of note: Maker-Education Initiative.

Papert quote from Mindstorms, Chapter 1: "But 'teaching without curriculum' does not mean spontaneous free-form classrooms or simply 'leaving the child alone.' It means supporting children as they build their own intellectual structures with materials drawn from the local culture. In this model, educational intervention means changing the culture, planting new constructive elements and eliminating noxious ones." There was a quote in The Children's Machine I had to posterize.

Video: They discussed the value beyond just making, and that 'just making' misses the point. That is human culture. The difference between learning by doing and learning by making, or why making is not just an activity. "School is famous for being overly structured... do all 9 steps and everyone gets the same result. (Barbie, anyone?) Blend maker cultures to appeal to a wider variety of learners; computation, electronics and textiles or paper, for example. Maker movement won't be equitable and diverse until its part of school. Concern for efficiency is a problem, as is emphasis on content that will make money. The old game design saw came up again, too: too often making is designed to hit a content objective rather than the content being involved in the making the learners are doing.

Part of what they said reminded me of a Star Trek exhibit at the science museum that had a section for what toys the engineers on the Apollo program played with as children.  Lots of construction.

Assignment: For this week's activity, create an Scratch project about things you like to do, then share it. (See 180ish projects in a Scratch forum.

This assignment reminded me of the Discovery Channel theme song.  I love my family and spending time with them, playing games and also making some. I love mathematics and I love teaching, too. Good writing - in book or film or tube.  I love music and any form of art, time in my faith life, that should have a part. Not much here that I can leave out, I guess learning is what it's all about. Boom-de-yada...



Press the green flag to play. Fun to make, once I figured out to do the image changes as costume changes for a sprite. I think I'd like to have Terry Gilliam's old job, if anybody wants to pay me to do it.

Scratch and 8th Grade Geometry

http://welovetypography.com
From twitter I found out about the K12 Online Conference. In particular about a Scratch session by Chris Betcher (@betchaboy on Twitter).  The session has a nice 22 min video about using the Scratch programming language with Year 5 students.  Very worthwhile info in a sitcom sized bite.  Chris also has a Scratch wiki devoted to getting students going with Scratch, and all the resources you need to get going.  Scratch is perpetually one of those things I'm going to investigate when I have obtained some sparemomentium.

I got a chance to work with a local 8th grade teacher who's looking into Geogebra.  He sent me some of the state standards he was interested in exploring, and I made up a couple sketches to play around.

The first is just a demonstration of the area formula for a parallelogram.  It seems so unreasonable that all parallelograms with the same base and height have the same area.  That connects with one of Geogebra's strengths to me - providing essentially infinite examples so that students can notice.


The next is probably pointless.  I was considering how to make a dynamic area measuring sketch.  I thought the advantage would be being able to change the figure, and easily check your answer regardless of how you've changed the shape.  I used sliders to build the shapes so that the distances would be nice.

The third sketch is for similarity - I'll post that later this week with the world's easiest activity.

MCC Math and Tech Workshop

This week I'm at Maria Anderson's Math and Tech Workshop.  I'll try to update this post as we go through the week.  There's a large Explorers group and I'm in the Adventurer's group.

Monday Morning
Adventurers brainstormed the following for discussion.  So look for more on this this week.
  • Wolfram Alpha
  • Attention-Getters
  • Textbooks: cost, open source
  • Geogebra
  • Vyew
  • Student interaction
  • Twitter/texting
  • Math Ed Research on Tech
Resources:
Social Media:
  • Use Facebook pages for students.  They like the page and get those updates rather than your updates.
  • Go over privacy settings with your students.  They are often ignorant of the reality. Check your own.
  • Linked In: limited use, like a modern rolodex.
  • Twitter: internet equivalent of drinking from a firehose.
  • Twitter is more collegial.  Follow people who have worthwhile info to you, get nearly instantaneous feedback, hashtags to organize.
  • Twapper Keeper (love that) to archive tweets.
  • Twitter is a completely public space.
  • Math Blogs: a node on Maria's MindMap of Spicing Up Mathematics
Monday Afternoon
Finally got time to play with Scratch.  I'm wondering about it as an activity directly for students, for preservice teachers, or as an instructional design tool to make activities.  Here's my first - kind of like pidgin Logo.

The end of the afternoon is working on Mathematica. It has developed quite a bit in the 15 years since I've last used it!
