在初中数学教材中,有许多有利于培养学生思维能力的内容,其教学价值不仅局限于帮助学生获得书中的知识,而且有助于学生思维能力的培养和提高.基于关键点的教学设计对于思维的培养十分重要,是提高数学课堂效率与促进数学能力发展的重要途径.本文以华师大版《数学》九年级下册《二次函数的实践与探索》(第2课时)为例,进行关键点教学设计的实例分析,供参考.一、教材分析1.内容分析(1)知识层面:二次函数的知识是九年级
In junior high school mathematics textbooks, there are many conducive to cultivate students’ thinking ability, its teaching value is not limited to help students get the book knowledge, but also help students to train their thinking ability and improve the design of teaching based on key points The cultivation of thinking is very important and it is an important way to improve the efficiency of mathematics classroom and to promote the development of mathematics ability.Taking the practice and exploration of the Quadratic Function under the Ninth Grade of Huazhi Normal University as an example, Analysis of the key point of teaching design for reference.A teaching material analysis 1 content analysis (1) knowledge level: the knowledge of quadratic function is the ninth grade
