This paper discusses the process involved in a change in curriculum at the Leafy Wood State School of Australia. The change involved most children who began attending the school in 1985 and 1986 (about 180 children aged 5, 6, and 7 years), their parents, 8 teachers, and the school administration team. The decision to change the style of curriculum was related to a concern that too many young children were kept at a disadvantage by curriculum practices in which all children were presented with the same learning experiences at the same time. This report looks at teachers' efforts to create and implement a curriculum which would cater to developmental differences among learners. This curriculum was based on mixed-age classes and hands on activity. Issues and events that influenced teacher actions are discussed. Topics of the report include: (1) preparation for change in the second semester of 1985; (2) the process of getting started; (3) consolidation; (4) facilitation of the learning process; and (5) tentative plans for future changes. Included in the text are photographs, policy and proposal statements, letters to parents and teachers, interviews, and journal entries. (RJC)
