[liveblog] Walter Bender

Walter Bender of SugarLabs begins by saying “What I’m all about is tools.” “The character of tools shapes what you can do.” He’s an advocate of “software libre” that lets the user be the shaper. That brings responsibility, which Walter wants to celebrate.

NOTE: Live-blogging. Getting things wrong. Missing points. Omitting key information. Introducing artificial choppiness. Over-emphasizing small matters. Paraphrasing badly. Not running a spellpchecker. Mangling other people’s ideas and words. You are warned, people.

He’s going to talk about http://turtle.sugarlabs.com

He goes back to Papert and Cynthia Solomon who in the late 1960s invented Logo. Fifty years ago. Then Jobs and Gates gave us babysitting: sw was there to be used, not an environment for creating ideas. You have to be given the tools and the knowledge.

In 1971, Papert and Solomon wrote “Twenty things you can do with software.” Walter today is going to give us a sense of the breadth of things you can do with software:


  • Using Turtle Blocks to draw interesting shapes, or create a paint program or paint with noise or attach pen size to time. “Once it belongs to you, you’re responsible for it it. And then it has to be cool, because who wants to be responsible for something that’s not cool?”


  • Challenges and puzzles


  • Add sensors, cameras, etc., create aa burglar alarm that photos the burglar


  • measure gravitational acceleration


  • Continent game written by a third grader


  • Build a robot


  • Model math


  • Collaborate across the network in a multimedia chat program


You can even extend the language. You can export your program into another programming language. A child wrote an extension to the language to download maps.

Turtle Blocks tries to make the learning visible to the learner — statistics about what the learner is doing, etc.

It’s got to be easy enough that you’ll try it, but it has to be hard if you’re going to learn. Many tools have low floors to enable easy entry but they also have low ceilings.

“Debugging is the greatest oppportunity for learning in the 21st century.” (Walter ties this idea to Cynthia Solomon.)

What motivates people: autonomy, a sense of mastery, and having a sense of purpose.
