高三数学复习是一项繁杂的系统工程,首先应弄清“为什么复习?”“复习什么?”以及“怎样复习?”这三个基本问题。复习的整体框架、常规的课堂教学以及测试反馈和讲评等一系列教学程序无不打上对上述基本问题认识的烙印。如果我们淡化或模糊了对基本问题的认识,那么,高三数学复习很可能被引入盲目而疲惫的题海之中。复习离不开解题,我们先从一道简单的试题说起。例1 sin15°+sin75°的值是。
Senior high school mathematics review is a complicated system engineering, we must first understand the “why review? ” “Review what? ” And “how to review? ” These three basic questions. Review of the overall framework of conventional classroom teaching and testing feedback and comments and a series of teaching programs are all marked on the basic problem of awareness of the mark. If we dilute or obscure our understanding of basic problems, then the third year math review is likely to be introduced into the blind and weary sea of questions. Review is inseparable from the solution problem, let’s start with a simple question. Example 1 The value of sin15 ° + sin75 ° is.
