Example of Just Letting Students Try to Figure it Out
I hope I do not start a war with this one and I have seen things like this several times before. The link is to a video of students trying to run their mousetrap cars while the teacher is most likely grading them. Only one car moves a reasonable distance, most do not move it all.
I saw a video of a model plane project in UK where not a single plane actually flew. Just have to question an assignment when almost everyone fails, shouldn't the students be given more coaching?
