The four year Teacher Development Program in Ohio features inservice programs which are based on adult learning styles; the learning is self-directed, experiential, job-related, problem centered, and individualized. Staff development activities encourage participants to be actively involved, allow flexibility and freedom of choice, use a variety of instructional formats appropriate to the learning objectives, and reflect actual conditions of educators. The programs are ongoing, have both long- and short-range goals, and are supported and encouraged through board of education policy and administrative leadership. Common to all is a climate for growth in the school that encourages personal and professional development. The 374 Teacher Development projects throughout the state are diverse, but several feature such common elements as: planning committees, needs assessment, experimental programs, staff development teams, teacher-led staff development, clinical supervision, video tapes, resource centers, inservice credits, small-group staff development, individual plans, building-level programs, and newsletters. Program coordinators' reports and statistical profiles of staff development activities are included in this report. (JD)
