高中数学无疑是学生学习起来较困难的学科,这门学科不但有计算更注重的是数学思维的运用。在函数知识学习部分,它是建立在初中函数的基础上进一步来研究其他的初等函数的。而初中的一次函数,二次函数和反比例函数又是初中生克服数学学习的一个难点,所以很多学生进入高中数学学习时有一种不适应感,尤其是高一的学生,一下子不会学习数学了。而我们有的教师为了让学生更会做题目,在教学的时候就把一些研究后的数学结论直接交代给学生们记,比如苏教版的必修4《三角函数的诱导公式》,在学习这一部分内容时,出现了大量的公式,于是教师们在学生还没有完全弄懂这些诱导公式的真正含义时,交给学生一句顺口溜:“奇变偶不变,符号看象限”。这句口诀,教师乐此不疲的用,学生是迷迷糊糊的听,经过调查,有许多同学并不理解这句顺口溜的含义是什么。像这样的案例有许多,所以,我要说数学,玩的不是技巧。要想真正的学会,学懂数学,就要真正的弄懂数学的概念,数学的本源。
High school mathematics is undoubtedly difficult for students to learn subjects, this discipline is not only calculated more emphasis on the use of mathematical thinking. In the function knowledge learning part, it is based on the junior high school function to further study other elementary functions. However, the primary, secondary and inverse functions of junior high school are another difficulty for junior high school students to overcome maths learning. Therefore, many students have an uncomfortable feeling when they enter senior high school maths learning. In particular, the freshman students will not learn math It’s Some of our teachers, in order to allow students to do more subjects, put some post-study math conclusions directly to students when teaching. For example, the required 4 “induction formula of trigonometric functions” As part of the content, there are a large number of formulas, so when the students have not fully understand the true meaning of these induced formulas, give the students a jester: “odd change no change, symbols look quadrant ”. This formula, the teacher never tired of use, students are stumbled listen, after investigation, many students do not understand what is the meaning of this phrase of jingle. There are many cases like this, so I’m going to talk about math and I’m not playing tricks. To really learn, learn mathematics, we must really understand the concept of mathematics, the origin of mathematics.
