I have been reading Mindset by Carol Dweck. One of the key differences between the Growth Mindset and Fixed Mindset is the attitude when faced with a problem that is above one's level of understanding. The Growth Minded people see it as a challenge, while the Fixed Minded people see it as a potential for failure. Learning opportunities present themselves everyday, and taking advantage of and acknowledging them would be a key to life-long learning.
With that in mind, I thought I would challenge my class with Einsteins Theory of Special Relativity. We approached this concept in much the same way that Einstein did as a clerk in a patent office; thought experiments (which by the way, are a powerful tool for children in all aspects of education). I walked them through his early thought experiments asked some probing questions, and we built up to a more complete view of the final theory. I didn't plan any activities, but we did several along the way to help us understand what we were thinking. It required me to be on my toes and aware of how they were interpreting the ideas I was presenting.
