In other words, transformation on the intrapersonal plane takes place when the novice teacher appropriates practices through active participation in the community of other educators. Learning the concept as part of teacher preparation classes is seldom sufficient. A major goal of teacher preparation is, therefore, the linking of useful primary tools with powerful secondary tools. In this sense, human beings use language and other signs to regulate their own learning activity as well as that of others. The collective group possesses the meaning, not the individual.
Teachers move and take other jobs or even leave the teaching profession.
Over a period of time, the original members of a school who objectified a particular meaning for an event or issue may no longer be at the school. Without ongoing public discussion about events, issues, and behaviors, schools would have no objectified meanings in their collective memory and would lose touch with their shared beliefs, values, and expectations. Finally , our view of teaching is that learning is the result of interactions among teacher, learner, and knowledge. From this view, the teacher is seen as co-active learner. Both teacher and learner try to transform information into knowledge which is meaningful, imaginative, and useful.
