数学概念是数学研究对象的高度抽象和概括,反映了数学对象的本质属性,是最重要的数学知识之一。正确理解概念是学好数学的基础。由于概念本身具有的严密性、抽象性和明确规定性,在教学上教师往往是以“告诉”为主,尽量让数学概念“强占”学生头脑,学生处于被动地位。由于中专学生文化课底子薄,学习数学较吃力;感觉数学知识枯燥、单调,对将来的工作学习没有什么直接作用,所以就排斥数学学习,有的甚至放弃数学学习。
Mathematical concept is a highly abstract and generalized mathematical research object, reflecting the essential properties of mathematical objects, is one of the most important mathematical knowledge. Correct understanding of the concept is the basis for learning mathematics. Due to the tightness, abstractness and definiteness inherent in the concept itself, teachers tend to teach “telling ” mainly in teaching, try their best to make mathematical concepts “occupy” the students’ minds and students in a passive position. Due to the fact that secondary school students have a weak cultural background, learning mathematics is more difficult; feeling mathematic knowledge is dull and monotonous, and has no direct effect on future work and study. Therefore, it excludes math and some even abandons maths learning.
