I was listening to an interesting podcast recently, where the guest and host were discussing human learning. Specifically the two speakers were discussing the optimum error rate to facilitate better learning. Research has found that optimum learning occurs when the subject is correct 85% of the time and makes errors 15% of the time. I really found this fascinating.
Imagine learning a new language or training in a new career field.
Initial learning will be slow and frustrating. In language, basic pronunciation and grammar rules must be spoon fed. And, in an occupational setting, names of co-workers, computer login information, and where to report to need to be written down and gone over frequently. But, in time, when learning a language proficiency and confidence develop allowing the student to explore real world conversations. And at work the new employee will be set on their own to manage their own tasks. At this stage the learner really begins to take off, probably due to them being in that 15% error/ 85% success state. Knowing enough to be dangerous but hungry to improve.
