Training teachers in coding, and thinking about e-waste/recycled robots

We recently had the second inset training day in programming related activities at Truro school. Following on from the previous session I didn’t want to introduce too much new stuff, so we concentrated on going back over Sonic Pi and Minecraft/Python programming in the morning, then discussed a lot more about our future workshops in the afternoon. These will include children from most of the primary schools in the Truro area and take place during the next term. I also wanted to use the day to work on some specific ideas the teachers wanted to get going. One of these involved running a Kinect camera with the Pi, which we managed to get more or less working – reading depth data in Python for potentially plugging into Minecraft at a later date.


The big idea I wanted to get feedback about was the use of robotics and electronics in conjunction with code (the photo above is my desk while preparing the day before). I didn’t have any lesson plans for this, but based on some comments from the first workshop and from playing a bit with this during CodeClub teaching I felt it might be good with this age group, who already know quite a bit about screen based activities. To keep costs down (as well as building in issues like e-waste) we’re planning to make use of recycled junk to extract motors from toys and hack them to do different things. It seems this doesn’t cause too many issues from safety POV (everything will be low-voltage and we can check everything beforehand), even the use of soldering irons seems to be acceptable as they have supervision.

The advantage of using code to move real things (as shown by a long history) is that it directly connects programming with the world outside of the screen (where it most certainly now has great importance in our lives), and at the same time results in teamwork – as it’s not easy for a single person to make a robot while programming it. When we tried this at Troon Primary they self organised into a group with one person programming while another was building stuff in lego and a third provided excited communication between them and more or less managed the task. Other programming activities tend to be more individualistic – with the possible exception of networked Minecraft, which is important but a very different form of collaboration.
