John Hattie's "Visible Learning: A Synthesis of over 800 Meta-analyses relating to Achievement" points out very clearly that the most powerful single thing we can do to enhance achievement is provide learners with feedback. The most simple prescription for improving education must be "dollops of feedback"!

"The effect-sizes for reinforcement is 1.13, remediation and feedback .65, mastery learning (which is based on feedback) .50; more specifically, homework with feedback is much more effective than homework without feedback, and recent reviews point to the power of feedback as a discriminator between more and less effective uses of computers in classrooms. This does not mean using many tests and providing over-prescriptive directions, it means providing information how and why the child understands and misunderstands, and what directions the student must take to improve."

More than anything else, feedback helps us improve and develop.
So, please let me know what you think?
