It is found that many middle school students like to take notes while attending classes in math class, so the effect of attending classes is particularly poor. It must be remembered that if you can think in science study, don't write. Many students especially like to draw the definition of the textbook in bold with that marker before they fully understand the content of the teacher's lecture. This is a typical deceptive class.

Listening has two concerns. One is listening difficulty, and the key point is the point that the teacher repeatedly emphasizes. The difficult thing is that the key content I haven't kept up with is generally the bold or bold words in the textbook. The method of recording is simple. Every time the teacher speaks, he will point to draw a star. The teacher will draw a few stars when he emphasizes it several times in this class. After returning home, he will sort out his notes and review the knowledge points in the order of priority from more stars to less stars, which will be clear at a glance.

If you encounter a knowledge point you don't understand, or if you are distracted, write down the key words in the book and ask your classmates after class, otherwise the teacher will make up this note in a minute or two, which will get twice the result with half the effort, or you won't even remember what the knowledge point is when you go home. Secondly, if you want to enlarge the effect of this method, you must learn to preview in advance.

Preview is divided into three steps: one look, two changes and three checks. At first glance, I read through the textbooks of the previous day, paying special attention to those bold fonts, new formulas and new definitions. This is the focus of the lecture the next day. The second word is that there are theorems and concepts that you can't understand when reading textbooks. Give them a question mark, probably listening and observing. If you encounter some old knowledge points you have learned before, but they are a little vague and can't be remembered, you must look up the textbook and review it again to clear the way for the next day's listening.

Many children don't open source when they study, but only work hard on the efficiency of listening, so when they learn knowledge, they are ambiguous, so they rely on it to brush the questions desperately, and the more they brush, the more confused they become. Therefore, it is particularly important to know how to preview and attend classes. Only with solid knowledge can we improve our homework efficiency and math scores.
