I’m doing some research on what is the most effective kind of feedback on what we as teachers can give to our students. I’ve been somewhat familiar with Carol Dweck, who has done great research on how to help students develop a “growth mindset” instead of a “fixed” one. Very simply put, we should praise effort instead of intelligence.
I also found a good online recorded interview with Ms. Dweck that Will Richardson did with her and posted on his blog.
Both are worth checking-out.
