In a new study by Wilson, R.C., Shenhav, A., Straccia, M. et al. they have found a sweet spot, where the learning is neither too easy nor too difficult. This sweet spot is when the student fails about 15% at the time.
It also ties in to a book we’ve read recently at Cortexio, Hooked by Nir Eyal, where the Hooked model explains how modern software is built to increase user interaction. By giving the user (or student) a variable reward the chances of the user returning to the application is much greater. (This is also why gambling can be such an addiction).
As a teacher it can seem like a daunting job to create individual learning paths for all students where they all have a 85% success rate.
This is why adaptive learning systems like Cortexio are so powerful. Cortexio creates an unique learning path for each student based on their performance where we aim at a 85% success rate.
More about our adaptive learning algorithms will be described in coming posts.
