The world of an individual, and the life-experience that unfolds within it, are marked by a certain pattern and a degree of consistency, features which enable us to understand the individual's experience. This chapter describes Sarah's experiential world. It follows the chronology of Sarah's work during the period of the study. The account will centre on the several changes that she made in her work, because these changes reveal important aspects of her work situation, her ideas and goals in teaching, and the way she experienced the teaching setting in which she found herself. The Learning Course had begun in the informal discussions of three teachers who had frequent contact with one another concerning school matters: Liz, an English teacher, had originated the notion of a Thinking Course based on the conviction that reading is a function of thinking. Liz, Dave, and Sarah had discussed the idea extensively.
