This project was conducted as quasi-experimental design. we assigned two classes of the third grade's students and the sixth grade's students into experimental group and control group, respectively. experimental group was taught materials of cube and cuboids for the third grade's students and materials of pillar and awl for the sixth grade's students by taking digital school network learning. the control group was taught by taking classroom learning. the learning effect and the distribution of van hiele level of geometric thought were compared between these two groups. moreover, we realized futher the geometry concept of the experimental group's students by a structured interview,and surveyed the learning attitude and opinion of the students using digital school network learning. keyword: Digital school network learning classroom learning,geometry curriculum,learning effect,van hiele level of geometric thought
