1变式教学对新概念教学的促进作用数学概念是整个数学知识体系的基础,对于数学概念的正确理解和掌握,直接关系到学生数学知识的掌握和数学能力的提高。但是数学概念往往叙述简练、高度抽象,学生感觉枯燥很难提起学习兴趣,由此造成学生对概念的理解和掌握往往存在诸多问题。通过变式训练,不仅可以使学生渡过概念学习关,而且还可以加深学生对概念的理解。
1 variant teaching to promote the new concept of teaching Mathematics concept is the basis of the entire mathematical knowledge system for the correct understanding of mathematical concepts and mastery, directly related to the mastery of students mathematical knowledge and mathematical ability to improve. However, the mathematical concepts are often narrated concise, highly abstract, students feel boring difficult to mention interest in learning, resulting in students understand the concept of understanding and often there are many problems. Through variant training, not only can students pass through the concept of learning off, but also can deepen students’ understanding of the concept.
