(183) Dunning-Kreuger Effect

Despite most of my class having had bikes for a few years now, they all found it difficult to make a reasonably accurate drawing of a bicycle. Everyone did manage to include two wheels, but placement of other components varied widely (or wildly!), if they were included at all. This was one of the more complete attempts from a pupil (10 years old) and I'm tempted to try the same exercise with my teaching colleagues to see if they could do better. 
This exercise was prompted by the reintroduction of Bikeability training at our school, and served as a lead-in to a discussion about the different types of bicycle and the main features of all bicycles. I then remembered that I had read an online article about someone who had taken similar 'from memory' sketches of bicycles and turned them into '3D' rendered images of what the designs would look like if actually built. Here's a link to the article. 
My blip title isn't really fair to my pupils as most of them actually underestimated their ability to draw a bicycle.
