You can’t force creativity, but you can remove the roadblocks.
At the risk of sounding like an old fart (because, after all, I am one): I believe I have noticed a decrease in the ability of incoming students to think outside the pigeon hole. I don’t think students are any less intelligent, but I do think it is one of the unintended side effects of “No Child Left Untested” foisted on the American public in a well-intentioned but misguided attempt to improve public education.
I don’t want to trot down that side path right now. Regardless of the cause, I am sure I see students struggling to think creatively. You might struggle as well.
