Socializing in school is only really allowed in the ~20% of time not made up of lectures / homework. E.g. Recess/Lunch/In-between classes. The other 80% is largely made up of lectures and homework. Ideally those percentages should be flipped. 80% learning via social learning(socialization) / 20% lecture.

Call me crazy, but I think humans learn best socially(conversationally) not by lecture via teacher. Talking and socializing should be integrated in how we learn and teach. The learning should largely be social between the students so that they actually learn material instead of just learning to temporarily remember the information for the next test.

The teacher should drift between the groups of students and clear up any misconceptions or disagreements that occur.
