The principle of my course/class design is the release of individuals diversity. Release is paired with constraint. The instruction includes the control/lead for releasing diversity.
The prime contrivances for the control are :
Preparing sound-subject-based learning materials.
Assignment of task and goal to students.
Evaluation of students' achievement in progress.
The extent of diversity to be released depends on goal, contents, phase and subjects of learning. For example, learning includes phase of 'obedient acceptance' : following discipline/model (imitating, copying) and excercising. It is not the case where the extent of diversity is set high. —
Setting up the standard for those is a subject of course design.
