about the necessity to understand scaffolding

Two of my children are possibly ill or possibly demotivated to go to school or both.

I have not been reading about underachievement for nothing.

Many teachers don't know that underachievement can be caused by too easy learning materials and lessons. They don't know about the mechanism nor do they know how much it affects children and their families. At the primary school I could see which teachers understand it just by looking at the grades of my children. You might argue that the grades only reflect the ability to teach and not how the teacher handles underachievement. True. In my opinion both are true. The successful teacher handles the underachievement better and gives better answers to difficult questions in the learning material. It is about scaffolding again.

"The first task during mediation is to discourage surface or superficial learning. Children are likely to engage in surface strategies as a matter of pragmatics; as a means of self preservation."
Now back to my reality. I hope it is the flue... but I'm pretty sure it is not. This is why we are thinking of moving to a region with better scaffolding, after five years of trying to manage.
