数学概念二次教学的实践与思考——以一道例题的教学为例

Practice and Thinking about Mathematics Concept Further-Teaching ——In a Case of a Teaching Example

数学概念二次教学是例题教学的一个环节,具有发现解题方法源泉和展现数学文化价值的作用.熟悉知识之间的内在联系是概念二次教学的起点,挖掘概念蕴含的数学思想方法是实施概念二次教学的途径,宽阔的教学视野是概念二次教学创新发展的基础,创造性的教学设计是概念二次教学的成败关键.

Mathematics concept further-teaching is a part of example teaching, which can make students find the source of the solutions to problems and display the cultural value of mathematics at the same time. Familiarity with the interrelation within knowledge is the origin of mathematics concept further-teaching;digging the methods of mathematical thoughts in the concept is the pathway of carrying out the mathematics concept further-teaching. A broaden teaching horizon is the base for the innovation and development of mathematics concept further-teaching and creative teaching design is the key to it.
