I’m not saying only teach interesting things, I’m saying teach things in an interesting and engaging way so that kids don’t feel the need to cheat their way through it to just get it done.
College is a different dynamic from a middle/high school classroom, but I don’t remember 95% of the material from my college engineering classes anyway, it’s the problem solving and information finding that I’ve retained and have helped me do the things I do. I remember the stuff from the classes that taught me the material in an engaging way though.
