Abstract
Metzler describes the theoretical bases and a general model for integrating teacher effectiveness research with sys tematic observation to evaluate physical education teaching. The ability to de lineate desirable teaching skills and to monitor preservice teachers' acquisition of those skills represents a new potential for improving theteaching of motor play and fitness. The author argues against holding physical educators accountable for student achievement until some per vasive instructional constraints are eased. The suggestion is made, how ever, that physical educators should be able to "account for" their pedagogical practices.
