Teaching styles can be considered from two approaches--the life style approach and the spectrum approach. The first is a relatively static approach borrowed from management research and organizational development. It identifies teaching styles based on Maslow's (1970) hierarchy of human needs. Teaching styles are seen as the interpersonal styles of behavior with others that grow out of people's needs and are the means of resolving personal concerns. By adapting Lafferty's (1975) management styles to teaching, one can describe seven teaching styles: achievement, self-actualized, humanistic-helpful, approval, oppositional power, and competence. The second approach, the spectrum design advanced by Mosston (1966, 1972), is based on the assumption that teaching style is a learned characteristic. It assumes that teachers can be trained to use alternative behaviors to fit various learning styles. According to this approach, seven teaching styles can be differentiated: command, practice, reciprocal, "slanty rope" or individual program style, guided discovery, problem solving, and creativity.
