Pedagogically and research-based intelligent adaptive learning technology accesses and stays in the Zone of Proximal Development (ZPD) for each learner. That means it provides the right next lesson at the right level of difficulty at the right time.
When work is easy, learners can do the work on their own without any help. It’s in their "comfort zone." If all the work a learner is asked to do is always in the comfort zone, no real learning will take place and the learner will eventually lose interest. Conversely, when the work is too hard, the learner becomes frustrated and will likely give up.
The area between the comfort zone and the frustration zone is the one where true learning will take place – the optimal learning zone. It’s the area where a learner will need some help or will need to work hard to understand a concept or complete a task.
By keeping the challenge appropriate, the learner is guided to be a mathematical ‘doer’ — someone who thinks and strategizes in ways they can apply in school and in their real life experience. This is optimal teaching and optimal learning.
