论教师信息技术应用观的嬗变

The Evolution of Teachers’ Information Technology Application Perceptions

教师的信息技术应用观，决定着信息技术作用于教学的效果，要提高教学中信息技术应用的广度、深度、频度和有效性，就应转变教师的信息技术应用观。信息技术应用观包括目标观、角色观和设计观。用混合学习的信息技术应用观去更新计算机辅助教学的信息技术应用观，是信息时代教育发展的要求。

Teachers＇ information technology application perceptions determine the result of information technology application in teaching. In order to promote the depth, breadth, frequency and effectiveness greatly, it is necessary to update teachers＇ information technology application perceptions. The information technology application perceptions comprise goal-perception, role- perception and design-perception. Teachers＇ information technology application perceptions based on blended learning should substitute for the application perceptions based on CAI.
