The purpose of this study was to develop the observation checklist to physical education class through analyzing the structure of observer's evaluation viewpoints. The questionnaire consisting of 31 items was prepared and applied to teachers who attended to and observed "the physical education classes (65) opened to the public'' at 13 elementary schools. With the Factor Analysis, 5 factors were extracted. These could be named as follows; 1) teacher's interaction, 2) learning environment, 3) momentum of instruction, 4) effective learning, 5) motivated learning. These factors were well consistent with the requisites for effective teaching suggested by findings of the researches on teaching physical education. From analyzing the correlations between a comprehensive evaluation item to physical education class and 5 factors, the significant relationships were recognized with all of factors. In comparing its relationships with attendance frequency (observation experiences) of teachers to "physical education class opened to the public'', the experienced teachers (attending 8 more times) tended to observe and evaluate with more various viewpoints than others. In order to develop a convenient checklist to physical education class,15 items were selected from 5 factors. As the result of the factor analysis, the stable structure consisting of same 5 factors was extracted. Thus, it is supposed that this checklist is available as a instrumentation for the observer to evaluate physical education class.
