Did you ever wonder why your teachers told you to study early and often for a test? Well it turns out that there may be something to it. You’re actually better off distributing your practise on anything rather than trying to learn something by cramming.
The problem is that it is easier to teach things in a group and not in a distributed pattern.It’s also more convenient although not better to learn that way. That’s why leadership and other improvement courses are all put in a day or a closely packed series of days, rather than over a longer period.
But studies by such researchers as Ebbinghaus and Dempster have been showing over the last century that distributed practise leads to more durable learning. I guess it comes back to the Seven Times Principle. You need to hear or try something seven times before it sticks.
If you’re trying to train someone on anything it will also work. You’ll have to get them to try it seven times before it will stick.
