摘要
平面几何解题活动是建立在掌握几何定义、基本命题和一定解题策略基础上的.学生平面几何解题能力的高低是学生数学能力的重要体现.在实际解题活动中,学生在习得基本定义、命题和解题策略后仍然会出现解题受阻的情况.为探究其原因,基于元认知策略,通过调查研究八年级学生在平面几何解题活动中更多地使用何种策略,以及何种策略对平面几何解题影响较大,从而给出适当的学习和教学建议.
The problem-solving activities of plane geometry are based on mastering geometric definitions,basic propositions and certain problem-solving strategies.The level of students’problem-solving ability in plane geometry is an important embodiment of students’mathematical ability.In the actual problem-solving activities,when students acquire the basic definitions,propositions and problem-solving strategies,they will still be blocked in problem-solving.In order to explore the reasons,based on metacognitive strategies,this paper investigates which strategies students use more in plane geometry problem-solving activities and which strategies have a great impact on plane geometry problem-solving,so as to give appropriate learning and teaching suggestions.
