Each Wednesday I meet with our Technologies/STEM student leaders to discuss initiatives they can lead at school. One of the biggest successes so far has been Genius Bar at lunch time. The way that we've established this is a pre-meeting the week before a Genius Bar to prepare the Student Leaders for the session, where we explore the software/hardware they're going to use (Often using the STEM kit from DoE & iPad apps) and brainstorm ideas for ways they could engage students in using them. With such a big school, we have promoted separate Genius Bars for Early Childhood, Middle, and Upper Primary. Generally these activities promote inquiry, explorative play and lots of fun!
