The parents I know from my home country are telling me that their kids are often struggling and are overwhelmed by the homework assignments. While this is already recognised also by the board that created the curriculum the changes are slow and half-hearted.

In my opinion, however, that is not even the problem, nor is it the problem that they are trying to solve. We usually forget that teaching is not "transfer" of knowledge. Each person actually recreates the knowledge in their own head and tries to fit it in with the rest of the world they know.

I believe that the best solution to education is to be able to personalize the new content in a way that naturally extends the student's knowledge. As already stated this may mean backtracking a little to be able to put the new knowledge onto a good foundation.

Normally, teachers cannot do that for each student individually so getting a program that could do that customization would be a great win.

Science homework should be able to be done in little more than it takes to copy it from an A student. It should not take hours, which it often does. I am looking through the lens of disadvantaged students.
