Abstract
This paper discussed the quantitative effect of the WBT (Web Based Teaching) system in a large class and improvement of a teaching method in the WBT environment. To evaluate the performance of the WBT, we investigate two relations between final examination and questionnaires in class, and between the former one and learning records. Some results of analysis showed that a motivation of student influences final examination. More effective operation under the WBT environment was proposed and its validity for the increase of education performance was proved.
