Here are some good recent online resources on motivation and rewards. I’ll be adding this post to My Best Posts On “Motivating” Students:
My Issue With Rewards by Chris Wejr.
Rewards: 2 Parent Perspectives by Chris Wejr.
Why progress matters: 6 questions for Harvard’s Teresa Amabile from Daniel Pink’s blog.
Is Money Enough To Motivate Employees? is a useful infographic.
On the Social Psychology of Agency Relationships: Lay Theories of Motivation Overemphasize Extrinsic Incentives is by Chip Heath.
Undermining quality teaching and learning: A self-determination theory perspective on high-stakes testing (I’m also adding this academic paper to The Best Posts On How To Prepare For Standardized Tests (And Why They’re Bad)).
I also write about teaching in a classroom with no rewards and my journey through it. I know a lot of people have found my posts helpful as well.
