There is evidence that by introducing more #diversity in the #classes, there are improved #academic results #education

Different #classes have different #hedonic motivations when learning new concepts, but should those be pre-determined factors as #prior experiences (past history) it would simply imply that no #positive changes will happen in the future.

And then there is always the question about those #students who do not #attend #classes in some #countries while in other countries there are no #schools built. Should "students" be #forced to #learn if they do not #feel or think that way? #socialengagementlearning
