在党提出教学必須改革的号召下,三角期末复习工作,必須贯彻教学改革的精神,更进一步提高教学质量。出色的复习工作必須是:使学生对新旧知識作更深入而明确的联想,从而更完善地掌握知識的內在联系,提高学生解决实际問題的技能技巧;切实弥补知識上的缺陷。根据几年来的教学实践和期末复习体会,在深入教学改革的今天,我們认为三角期末复习应该注意以下几点。茲就教材程序介紹如下,議供同志們复习时参考。一、加法定理我们知道,加法定理及由它推导出的各种公式与同角三角函数基本关系式是三角恆等变換的基础。复习这段教材,必須加强公式之間的內在联系、解題技能技巧、解决学生存在解題困难的教学:并且注意和物理、技术等的联系。
Under the call of the Party to put forward the need for reform in teaching, the review of the end of the triangular period must implement the spirit of teaching reform and further improve the quality of teaching. The outstanding review work must be: Make the students more in-depth and clear association of the old and new knowledge, so as to better grasp the intrinsic link of knowledge, improve students’ skills and skills to solve practical problems; and effectively compensate for the defects in knowledge. According to the teaching practice and end-of-life review experience of the past few years, in the in-depth teaching reform today, we believe that the review of the end of the triangle should pay attention to the following points. The following is a brief introduction to the teaching material program, which is provided for reference by comrades when reviewing. 1. The Addition Theorem We know that the addition theorem and the various equations derived from it and the basic relational expression of the same-angle trigonometric function are the basis of the trigonometric identity transformation. To review this teaching material, we must strengthen the intrinsic relationship between formulas, solve problem-solving skills, and solve the problem that students have difficulties in solving the teaching problem: and pay attention to the connection with physics and technology.
