Teachers' educational technology competence training takes plural forms, one of which is web-based training. However, for many educational institutions in mainland of China, the online training effect is not satisfied for providing teachers with uniform resources and activities without considering the personal factors when the role of a teacher has changed into an adult learner. In this paper, a preliminary survey is used to figure out the influential factors of training effect, and a decision making model is proposed by KAFR tool, which is developed for observing both the relation between learning styles and learning activities, as well as the relation between learning styles and learning resources. The model could be used in the generation of user model by describing teacher's profile in any adaptive educational system.
