1设计说明1.1学情分析(1)笔者所在学校的生源在本地区处于中等水平,第一轮复习时学生已经基本掌握平行四边形、投影与相似三角形、锐角三角函数等知识,但是由于缺乏较系统指导,学生对于利用相似三角形测量物体的高度问题的解题策略、解题技巧、解题规范以及解题的信心均有待进一步提升。(2)基于学生的学习水平以及中考专题复习的特点,确立本专题复习的教学目标、重点、难点。
1 Design Description 1.1 Analysis of Academic Situation (1) The students in our school are at medium level in the region. During the first round of reviewing, students have acquired basic knowledge of parallelogram, projection and similar trigonometry, trigonometric trigonometry, etc. However, due to the lack of systematic Guidance, students to use similar triangles to measure the height of the problem-solving strategies, problem-solving skills, problem-solving norms and problem-solving confidence to be further enhanced. (2) Based on the students’ learning level and the characteristics of the special subject reviewing, the teaching objectives, key points and difficulties for the review of this topic are established.
