一、教学设计的背景设计本节课的主要原因是学生在解有关二次函数综合题时往往比较困难,而教师在讲解二次函数综合题时,因每道题的知识背景不同,从而在解决这类问题时,花时多且效率低下,学生学习的效果很差.所以在设计问题时,我采用了同一知识情境,学生不感到生疏,同时把二次函数中的难点、易错点在各小题中充分反映出来,通过分类,能起到事半功倍的效果.二、主要环节1.二次函数综合题在中考中的位置,介绍中考中二次函数常见的类型,以及在综合应用中常见的知识点.
First, the background design of teaching design The main reason for this lesson is that students are often more difficult to solve the comprehensive questions on the quadratic function, and teachers in explaining the quadratic function comprehensive questions, because of the knowledge background of each question is different, When it comes to solving such problems, it takes too much time and is inefficient, so the effect of students’ learning is very poor, so when designing the problem, I adopt the same knowledge situation and the students do not feel strange. At the same time, In the small problems fully reflected, through classification, can play a multiplier effect.Second, the main part of a 1. The quadratic function comprehensive questions in the test in the position, introduce the secondary test in the common type of test, and in the comprehensive application Common knowledge point.
