@AlexOverwijk repeated his 2014 #tmc session this year which pleased participants such as @gfletchy who tweeted:
This 2014 blog post outlines the use of white-boarding, which I believe takes the technique to the next level. Often times, we see students within classrooms using small whiteboards only visible to those sitting near. Overwijk discusses the impact of the whiteboards being posted on the walls around the room. Students work in small groups on a really good task, which opens the opportunity for discussion and makes thoughts of those in the room visible to everyone. This is a part of the “big wheel”.
