How To Get From Blocks to Text With Robotics Coding

So many rich block-based programming environments have become available during the last several years. The release of Scratch into the world by MIT Media Lab's Lifelong Kindergarten Group catalyzed the invention of similar block-based environments for all sorts of purposes and a revolution in novice learners' ability to use the building blocks of computer science to imagine and make things. Block-based environments provide the important affordance of building programs without making

Games and Controllers With Scratch, MaKey MaKey, and 3D Printing

I first wrote this post a year ago. This past year I revised a couple things as I did the project again, and the revisions will be noted.
We got a Makerbot Replicator 2 last December (now a year-and-a-half ago) and one of the projects I came up with turned out really well, and I think is worth sharing. My 7th graders designed key press controlled games in Scratch, then designed hand-held controllers with embedded switches, and we connected MaKey MaKeys to the leads on the switches for a great game experience. The highlights

LED Handbell Gloves

This project was quite long in development, more than a year, in fact! I learned a lot about technology design so the process is worth recounting. Two then-juniors I taught in a robotics class, Susannah and Nicki, now graduated, asked me for help with an idea they had. They were members of a handbell group they had played with for 5 years and wanted to make handbell gloves that light up each time they play a bell, unveiling the gloves for one piece in their final concert. We batted around some ideas. They thought about using a Lilypad Arduino and an accelerometer but I thought we

Animate Poems With Scratch

Some of the most successful tech integration collaborations happen at unexpected times. Our 5th grade English teacher, Jenny Kirsch, asked me to help brainstorm ideas for her students to somehow animate excerpts of poems they had written. It was meant to be a quick end-of-year activity, a fun way for the students to extend and present their work. What resulted was a very nice opportunity for

3D Print Pagoda Project

Our 5th grade history teacher was doing a study of Vietnam with her class and wondered if her students could make and print pagodas. After looking at some examples and doing a couple test prints I settled on a general design that featured hexagonal or octagonal base with openings on some or all sides, which was repeated
