数学实验:让几何概念的理解更深刻

Mathematics Experiment and Geometrical Concept Interpretation

数学实验是几何概念教学的"脚手架",是学生自主建构概念意义的重要学习方式。利用数学实验进行几何概念教学,能使情境和经验再现,让操作和智慧相融,促理解和创造共生。教学中,教师要立足学生的数学现实,以学生的视角进行观察和思考,从实验时机的把握、序列的设计、材料的选取以及方式择定等方面进行探索,使学生对几何概念的理解更加深刻。

Mathematics experiment is the scaff old of geometrical concept teaching and also an important way of students’autonomous construction of conceptual meanings.This teaching method can relive the situation and experience,integrate operation with wisdom,and improve students’understanding and creation.Teachers should be based on the mathematic reality of students and make an observation and thinking from the angle of students.Furthermore,teachers should explore from such aspects as capturing the time of experiment,sequence designing,material selection and choice of approaches to improve students’understanding of concepts more deeply.
