在二次函数方面的知识的教学过程中,一线的初中教师常常会发现,无论是从教材的编排还是考试的分值和难度来看,二次函数都属于初中阶段数学学习的重点和难点知识,由于它的图形线条多,考查的题目又时常和几何知识联系在一起,解题难度大,造成许多学生在学习该模块知识时失分较多,继而出现丧失自信的情况。因此,为了让一线的数学老师们提升初中数学二次函数的教学效率,并帮助孩子们提高该模块学习的成绩,在接下来的文章中,我将把自己多年从事初三阶段的二次函数教学中得到的一些思考分享给大家,希望能够对大家有所帮助。
In the process of teaching quadratic function knowledge, front-line junior middle school teachers often find that the quadratic functions belong to the emphasis and difficulty knowledge of mathematics learning in junior middle schools, both from the arrangement of teaching materials and the score and difficulty of examinations , Because of its graphic lines and more exam questions are often linked with the geometric knowledge, difficult to solve the problem, resulting in many students lose more points in the learning of the module, followed by loss of confidence. Therefore, in order to let the first-line math teachers improve the teaching efficiency of the second-order math function of the junior high school and help the children to improve the learning of the module, in the following article, I will take the second-order function Some ideas gained in teaching can be shared with everyone, hoping to be helpful to everyone.
