在总路线的光輝照耀下,我們目前教学工作出現了新的跃进局面。为了更进一步提高教学貭量,做好期終复习工作是非常重要的。通过复习,可以帮助学生把新学知識系统化、补充知識上的缺陷和进一步培养学生解題的技能和技巧。我們充分发动了羣众,深入了解了学生的問題和要求,根据下述精神制订了高二三角复习提網: (一)加深基本概念的讲解,揭露教材內在联系,把知識系統化。我们把本学期教材(課本一至四章)分为三角函数定义和基本性质;三角函数式的恆等变換两部分。前者以三角函数线为中心貫穿全部内容,就可以由三角函数定义,进一步研究三角函数符号、定义域、容許值范围、周期、图象,使学生能完整清晰地掌握教材系統。 (二)学生最感困难的是解題,看到问题不知如何下手。因此,我们在复习中应充分揭露公式间的內在联系,帮助学生在理解的基础上記忆;同时,着重于解题能力的培养。我們把同角三角函数相互关系、誘导公式、加法定理等合为一部分。做些問題类型的分析。指出应如何根据题目的类型找出解題的途径,并多做些綜合性題目的练习。 (三)着重复习学生过去学得不牢固的地方,如周期、图象等。下面是具体复习提綱。
With the brilliant light of the general route, we have seen a new leap forward in our current teaching work. In order to further improve the teaching quality, it is very important to do a review of the end of the year. By reviewing, students can help students to systematically integrate new knowledge, supplement defects in knowledge, and further develop students’ skills and skills to solve problems. We fully mobilized the masses, thoroughly understood the students’ problems and requirements, and formulated the Gao 2 Triangle Review Raiders according to the following principles: (1) Deepening the interpretation of basic concepts, exposing internal links in the teaching materials, and systematicizing knowledge. We divide the semester textbooks (Chapter 1 to Chapter 4) into trigonometric function definitions and basic properties; trigonometric functional transformations in two parts. The former uses the trigonometric function line as the center to pass through the entire content, and can be defined by the trigonometric function, and further study the trigonometric function symbol, definition domain, allowable value range, period, and image so that the student can grasp the teaching material system completely and clearly. (B) The students find it most difficult to solve problems, and they do not know how to start with problems. Therefore, during the review, we should fully expose the internal relations between the formulas, help students to memorize on the basis of understanding, and at the same time, focus on the cultivation of problem-solving abilities. We combine the mutual relations of triangle functions, induction formulas, and addition theorems. Do some kind of analysis. Point out how to find the solution to the problem based on the type of the topic, and do more comprehensive exercises. (3) Places where repetition of students’ past studies is not strong, such as cycles, images, etc. The following is a specific review outline.
