Abstract:

Under the influence of epidemic, non face-to-face teaching environments relying on the Internet are increasing, which puts forward new requirements for the development of students' high-level thinking and the cultivation of problem-solving ability. Based on the online teaching environment, this study adopts the method of experimental research, takes the ninth grade students as the research object, designs the reasonable construction method of knowledge map, and carries on the experimental research on junior high school students' mathematical problem-solving ability with the help of knowledge map. The results show that knowledge map, as a thinking visualization tool and a learning analysis method, plays an effective role in promoting junior middle school students' ability of making strategies and implementing strategies.
