It struck me as I looked at this list that it’s a lot like what I believe about children and computers: that student choice, plus time for unstructured access to lots of different computing experiences is crucial to developing literacy and fluency with computers. My vision includes a teacher or mentor modeling passion, collaboration, interest in the subject, and offering experiences that challenge students without coercion, tricks, or rankings. If I had to come up with a catchy acronym, I’d call it Sustained Tinkering Time (SST).
