“试误”教学在数学教学中的实践

摘要

This paper explores a teaching method of trial and error and its application to the teaching of mathematical idea, theorem and formula, assignment evaluation and exercise class, according to the basic mode of trial and error teaching as well as its operating procedure. Practice results indicate that this proposed teaching method can intensify the teachers’idea of teaching as a center as well as the students’consciousness of principal parts in teaching, train, cultivate the students’originality and their habit of self-access learning, develop the students’critical thinking and differentiating consciousness, and strengthen the students’cooperative and interactive learning consciousness.%　　根据“试误”教学的基本模式及其操作程序，探讨了“试误”教学在数学概念、定理公式、作业讲评和习题指导课等的教学应用。实践结果表明，该教学方法能强化教师的主体教学理念和学生的主体意识、培养学生的独创精神和自主学习习惯、开发学生的批判性思维和鉴别意识、增强学生的合作学习和相互交流意识。
