How to study chemistry and history in the third year of junior high school, and how to arrange the s

The knowledge in junior high school is actually relatively simple, so there is no big problem with self-study.

If you have a relatively good foundation, then as long as you follow the teacher, you can basically do it. Buy a few more books to review for the high school entrance examination outside of class, then you can easily and solidly take the high school entrance examination.

If your basic comparison is not good, and it is the kind of thing that needs to make up for a piece in the east and a piece in the west, it is recommended that you take advantage of the two months of summer vacation to read the books of the first and second years of junior high school seriously. At least one of the subjects relative to the liberal arts has an impression, and the subjects of the relative sciences do every question in the book solidly, and ask questions quickly if you don't understand.

Originally, reading is a process of accumulation, and there is no fast food. If you want to smile to the end, then you have to give. So it's not wrong to read it according to your actual situation.

The easiest way for chemistry and history in the third year of junior high school is to memorize, chemistry you have to memorize the element symbols, as well as the reaction formula, history is even more, but pay attention to the method, memorize it once three days later, you must memorize it, repeat it a few times and you will pull.

The foundation is very important, and it is necessary to focus on the weak subjects.

The first is to have a good attitude and study carefully. Learn to generalize and summarize.

The time spent on chemistry in the third year of junior high school does not require a lot of time, first of all, it is necessary to strictly complete the teacher's requirements, homework, and the memorization of equation answering skills can not cut corners, and in addition, you only need to take 5 minutes every day to read the content or formula that you have learned that day or before. As for the history of the third year of junior high school, the old man has deep feelings and reads textbooks! Textbooks are the source of all things, read aloud, the louder the sound, the better, and read the wrong questions, just repeat the two items.

Learn chemistry well in the third year of junior high school, and the plan is as follows:

1. Adjust your mood. Don't be afraid to learn badly, and don't listen to others - easy to learn is very careless;

2. Preview before class, it is best to make reading notes; When you're busy, it's better to watch it even once; Listen carefully and interestedly in class, and don't easily dislike or look down on the teacher, which will affect your chemistry learning ability; It is necessary to keep in mind the completeness of the notes, especially the completeness of the knowledge points and the accuracy of chemical terms;

3. Use a few minutes to review and consolidate in time after class, don't delay, the longer the time, the more you forget;

4. Don't leave homework and practice behind, you must keep up with it, so as to consolidate the knowledge you have just learned again;

5. The exercises or test papers that the teacher has talked about, and the questions that you don't understand well, should be sorted out in time, and the typical questions should be taken notes, so that they can be reviewed and strengthened in the future;

6. Chemistry knowledge is scattered and difficult to remember, so it should be consolidated and reviewed at any time.

I, the head of the school's chemistry department, can ask at any time!

Chapter 1: In view of the fact that the basic problem of mastering the knowledge points is not very big, then we should train on the basis, especially find a way to do the questions, because the discipline of chemistry is a particularly miscellaneous one in these subjects, so if you want to learn chemistry well, you must learn to use the knowledge points you have learned in various types of questions, so the focus in the future will be on this aspect. Only in this way can we learn chemistry well.

Of course, in the study, our first task is to grasp the knowledge points of compulsory 4, first build their confidence, study with an optimistic and positive attitude, and strive to achieve good results in the exam. Chemistry Teacher: Han Dong October 30, 20xx Chapter 2:

Chapter 1: Chemistry Teaching Plan for Junior High School Chemistry Teaching Plan for Junior High School I. Student Analysis: I teach only one class, 168 classes, and these students come from uneven foundations, some have a solid foundation and better grades.

Of course, there are some students who do not develop good study habits and behavioral habits. In this way, it is necessary to teach students according to their aptitude, so that they can continue to develop and progress on their original foundations. Overall Situation Analysis:

The polarization of students is very serious, the proportion of excellent students is small, and the proportion of learning and development students is too large, and most of them are not enthusiastic about learning and do not seek progress. Most of the top students are enthusiastic about learning, but they have serious deficiencies in problem analysis ability, calculation ability, and experimental operation ability, especially the knowledge expansion and comprehensive ability of knowledge, and the students' response ability is weak.
