Researchers have long tried to relate personality types to teaching and learning styles. It is believed that the psychological theory behind the Myers-Briggs Type Indicator (MBTI) can help university teachers to accept variety in teaching and learning approaches. This paper makes some assertions about the personality traits of academics and students. These traits can create harmony or discord for individual students, depending on whether their approach to learning matches the teacher's approach to teaching. Although some teaching strategies can be useful for a whole class, differences among students make it necessary to diversify those strategies. (Contains 3 tables.)
