COMPARISON OF DIFFERENT COMPUTER APPLICATION MODES IN INSTRUCTION OF PRIMARY SCHOOL GEOMETRY
小学几何教学中计算机不同应用模式的比较

There are two instructional modes when computer is applied to education, Tool mode and Tutormode. This paper reviewed issues of theoretical and empirical researches on these two fields, andproposed a cooperative tool mode with Windows PBrush. A one-week instruction in geometric reasoningwas conducted and its effect on geometric knowledge and reasoning ability was investigated by pre-posttest experiment. Attitude and motivation of students and teachers were investigated with surveys andinterviews. it also analyzed learning process of students with work analysis method. The result showedthat:Cooperative tool mode instruction brought on significant outcomes in reasoning ability, geometricknowledge, and study motivation than cooperative CAI; proper instructional methods can promoteinstruction effects, feature and quantity of information representation can affect the learner's cognitiveconstruction.
