Most Efficient Learning

So in Anderson's Learning and Memory, there is a study about baseball coaches teaching batters. They try giving instant feedback after every single pitch and feedback after every seven pitches. Apparently knowing what you did wrong after every pitch is counter productive and less effective than learning what was wrong every seven pitches. This has consequences for teachers more than students. Students will learn how they learn, but teachers must be wary of correcting every single little thing. The student won't learn as quickly or effectively if told what they did wrong on every trial. You must let them make their mistakes many times before correcting it. The reason is because usually the student knows they are making the mistake, but it takes some time to fix it. Whereas a mistake that occurs over and over again is probably unnoticed and readily fixed by an outside observer.
