I believe true learning involves active thinking and interpretation. Thus, the best classrooms are those where both the teacher and the students learn from each ching should challenge both the teacher and the student. Teachers should be challenged to deliver the course materials successfully in different ways and from different perspectives. Students should be challenged by the teacher and the course materials. According to me, the best way of learning Medical Microbiology is to encourage the students to go through the course material in detail, ponder about it and question its validity and application. Science is all about questioning, and no progress was ever made without it.
