Assessment of proper control and suitable learning environment can proceed through collection of data related to teacher planning, student attitudes, and interactive behavior of teachers and pupils. The use of such data for improvement of instruction can provide valid and feasible assessment procedures. Directed skill training, competency contracts, and inquiry projects are all appropriate means of assessment and improvement at this stage in the development of techniques for the evaluation of teacher effectiveness. Inquiry projects can involve comparisons of behavior with a model, comparisons of behavior with stated behavioral objectives, and comparisons of behavior over time. Peer cooperation in collection of interactive data is apt to contribute to development of skills in coding behavior and therefore to lead to greater behavior change. (Author)
