Third: pick up the pen cap on the ground, or you won't find it after class ... this is very important.
Fourth, we should take notes and record the knowledge points and examples in class clearly for future use! ! ! Take notes, take notes, take notes, and say the important things three times! ! !
Children who can successfully enter junior high school believe that the first three points must be done well, but the fourth point is particularly important in the study and life of junior high school, and sometimes it is even more important than doing problems!
1. Good memory is better than bad writing.
This truth was instilled in me by my teacher when I was just in junior high school, and a lot of facts have proved to be true. The research shows that students who take the test immediately after the lecture can generally remember half of the lecture content of 10 minutes, and if they take the test after 48 hours, they can only remember 20%. Moreover, junior high school mathematics has more knowledge points, concepts, definitions, properties, theorems and questions than primary school mathematics. The amount of tasks in each class is not small, and even a good memory can hardly resist the knowledge point of increasing the amount without increasing the price. And sometimes it is very clear and thorough to listen in class, but it is very distressing to review this knowledge point in a few days. So take notes, take notes, take notes!
2. Effectively prevent the number from slipping in class
In class, teachers should not only talk and analyze, but also write on the blackboard at any time. Then, at the moment when the teacher turned to face the blackboard, I believe that it is extremely easy for students to slip away. Even if they don't sneak and stare at what the teacher writes, isn't it a good use of class time? Then, if you can take notes with the teacher at this time, you can not only write the knowledge points in class to deepen your memory, but also prevent active thinking from slipping out of class, then classroom efficiency is hard to think about! So, take notes *3.
3. Your own study materials
There are so many auxiliary materials on the market, which are comprehensive and comprehensive. There are various questions and mid-term exams in minutes. The printed fonts are neat and beautiful, and can be directly used as notes. But is this really good? The knowledge points in teaching AIDS are too objective and too general, which is not conducive to personalized learning. If you don't let everyone be ignorant, you have had the experience that you understand what you write and you can't understand what others write.
You know, it's not just what the teacher writes on the blackboard that takes notes. The most important thing is to remember your weakest link. If you don't know what kind of questions it is, just focus on it in your notes, and then add a few more types of questions. Which knowledge point has its own new insights, as long as I focus on the analysis with the colored pen next to it, this knowledge point will be engraved in my mind unnoticed. When it comes to review, a note can be read faster than a few pages of teaching AIDS, and the knowledge points can be recalled thoroughly, and the review efficiency is higher.
"*" finished taking notes! Yes! Sex! Next, let's walk into the big house hand in hand, shoulder to shoulder and with good notes!
A. big notes:
Except physical education class (the size of A4 paper), please prepare a large notebook with a thickness of not less than 1CM for each course. The paper should not be too soft and thin, and the binding should be strong, so that it can stand reading, because they will follow you for three years! Methods When you took math notes in those years, there was only a book on the left and a book on the right. When reviewing in the third grade, I couldn't find my previous notes, which was particularly miserable. Only in high school did you learn your lesson. Use at least four colors of pens: black pen, blue pen, red pen and green pen to highlight the key points, difficulties and weaknesses, and the more prominent, the better. Color label, stick it on the blank space of the note paper, and write the key words to find the note page of each semester conveniently and quickly.
B. Blank area
Mathematics is also an art, so we should leave blank (the words in the art world are also commonly used in Chinese, that is, leave corresponding blank and leave room for imagination). How to check in? For wall cracks, it is suggested to take class notes on the left side of each page, and space should be reserved on the right side of 1/3 or 1/4. Don't fill the whole page with notes. The blank parts should be used to supplement the methods and summaries when doing exercises and reviewing the corresponding knowledge points, and to sort out the wrong questions. In addition, after each chapter's notes are recorded, one page of notes will be reserved for the final review ~ Do you think that the current notebook with a thickness of 1CM is not enough ~
C. Jane has a coup
If the speed is too slow to keep up with the rhythm of the teacher's lecture, the notes are also wrong. In order to listen and remember correctly, you must improve your writing speed! When taking notes, you don't have to write every word completely, but take clarity as the guiding principle. Make good use of symbols or abbreviations, such as "plane rectangular coordinate system" as "straight line", "isosceles right triangle" as "equilateral triangle" and "parallel" as ∨. This is not laziness, it is wit!
D. Graphics can talk
A good figure is better than a few lines of words and formulas, and the attached figure is a good example …
