Half an infinity ago I took a short stint trying to be a teacher. I failed. I had ideas they did not like, treated the childrenas equals, which they did not liek and a number of other things.
Plus: I had the misfortune to meet the biggest heap of Waste-DNA in one person I have so far encountered. But I digress.
In the following video displays beautifully, how you could teach children higher physics, mathematics, biology and handycraft all in one go. And because it would be so beautiful and effective, an approach like that will not be used in a German public school in the forseeable future. School is not supposed to be fun now, is it?
