This project brought together educational theorists and practitioners in Spain to create a model of teacher training based on research by trainees into their own practice and to create a curriculum of Spanish language adapted to the students of the location where it was developed. The project was undertaken in the context of educational policy reforms which called for cooperation among education professionals and for teachers to make their own curricula adapted to their own schools with the general curriculum as a guide. The project took four stages each of which required a dynamic process in which the four moments of planning, action, observation, and reflection occurred in a spiral pattern. Specific components included weekly meetings of all members and putting plans into practice. Data collection included tape recording of the sessions of seminars, records of seminars, working documents, participant observation of classrooms, video recording, and partial reports. The process made possible a joint reflection on the questions and hypotheses arising from the dynamics of the members' interaction. Among the conclusions were: (1) setting into practice the model of action research creates a new perspective on the approach itself; (2) theorists had the chance to acquire practical competence without disturbing class life; and (3) working on a specific project served as a model for generalization to other levels.
