> Perhaps Harkness could be modified to be less expensive to implement. I think it could to some extent. For some students doing self-paced, online learning for lectures and then following that up with individualized/small-group problem-solving and discussion with peers/tutors/teachers certainly does work. But kids in early high-school and younger? Someone really needs to be there for them all the time. BTW, I also had a math instructor that got miraculous outcomes by finely grouping students within each classroom according to skill. She would individualize attention to each group, and then move individual students up or down to different groups depending on their ongoing performance/mastery. She literally had what I would recognize today as a kan-ban chart on a blackboard in the classroom and we, the students, were the projects/products. Thinking back about it now, it must have been a herculean effort. It was also the 70's in a Catholic school and she had total autonomy. I seriously doubt a talented teacher could get away with something like that today.
