The purpose of this study is to examine the effects of teacher behavior, especially the interaction behavior in Physical education class on the student learning behavior (ALT-PE) and the learning effectiveness. Sixty-four physical education classes taught by 22 elementary school terchers (contained 3 Student teacher) were studied for this purpose. In order to analyze the teacher and student behavior during physical education class, the instruments of CAFISA and ALT-PE Observation System were used. An instrument of the student evaluation to physical education class (questionare) was applied to measure the student learning effectiveness. Main findings are as follows; 1) "Praise or encouragement" showed significant positive correlations with ALT, motor ALT, and so on. But "Criticism" had a significant negative correlation with ALT. These results were consistent with the preceding studies. Thus, it was confirmed in this study that teacher's positive interaction would make student learn actively in the class. 2) "Praise or encouragement" had significant positive correlations With 7 items of the student evaluation instrument. Conversely, "Criticism" showed significant negative correlations with 6 items of it. "Lecturing and information giving" and "Direction" also showed negative correlations with the student evaluation. 3) These facts suggest the effect of the teacher behavior in which the frequent positive interactions lead to better learning results and the frequent negative interactions bring worse results.
