The SSDL model suggests that problems may arise when the S3 approach of critical pedagogy conflicts with the need S1 students have for being taught. But not all adults will become self-directed when told. On the other hand, I cannot leave the students by themselves. The opposite of these two possibilities is being radically democratic. That means accepting the directive nature of education.
Every stage requires balancing the teacher's power with the student's emerging self-direction.
Most people seem to think that there is one way to teach well. Good teaching does two things. Good teaching is situational, yet it promotes the long-term development of the student. Conflicts among teachers with different styles. In typical polarizing fashion, each group compares its virtues to the other's faults.
