1, Mathematics: Junior high school mathematics knowledge is different from primary school mathematics knowledge, and it has begun to develop into abstraction, paying more attention to the application of logical thinking. In particular, it should be noted that mathematics, as a highly related subject, requires students to understand all the knowledge points in place, otherwise it will become more and more difficult for them to learn later.
2, physics: junior high school physics begins to learn from the second grade, from shallow to deep. However, the knowledge system of physics is huge, so it is not difficult for junior high school students even if they only need to master the basics of each major knowledge section. Junior high school physics needs rote memorization and calculation, as well as knowledge of physical drawing and numerous symbolic formulas. Junior high school subjects have a large amount of knowledge and are the most difficult to learn.
3. chemistry: chemistry is a subject that will be learned in the third grade. Part of the reason is that it is difficult to understand chemical knowledge, which requires students to have a high academic foundation and cognitive level. Chemistry knowledge is both novel and unfamiliar to junior high school students. Because there are many symbols of chemical elements, various equations and experimental processes also need students to understand and remember, so chemistry is difficult to learn well.
4. Language: Many students think that language is simple, but it is not accurate. Junior high school Chinese is a watershed. At this time, we should pay special attention to classical Chinese reading and modern Chinese reading to lay a good foundation for high school study. Learning Chinese well will get twice the result with half the effort in other subjects.
5. Biology: The knowledge that junior high school students need to master in biology is relatively simple, and the main purpose is to help students understand biology initially and stimulate their interest in learning. The biological knowledge at this stage rarely involves calculation, so it is easier to learn.
6. English: I don't know much about English in junior high school. I mainly study basic English words and grammar, interspersed with some expanding knowledge. Many students have been exposed to English learning since primary school, and it is easy to get started. Even some primary school students who have no English courses will not find it too hard to face junior high school English.
7. Geography: Junior high school geography is a subject that many students are interested in. The geography subject at this stage is mainly to let students know about the world we live in and some geographical common sense, which is interesting but not boring. Learning is based on understanding, supplemented by memory.
8. Politics: Junior high school politics is connected with primary school ideological and moral, morality and rule of law courses, aiming to help students understand political and legal common sense and universal social moral norms, and initially help students establish correct political, moral and values. The knowledge points involved are daily and easy to understand.
9. History: History is a relatively simple subject in junior high school. The main purpose of teaching is to let students understand simple Chinese and foreign history, help students establish a correct view of history, learn from history and apply it to life. The knowledge points are easy to understand and not difficult to remember.
Matters needing attention in junior high school classroom
1. Try to stay focused and listen carefully in class. Actively participating in class discussions and asking questions will help to better understand knowledge. Recording key contents and key knowledge in time is helpful to review and review the learning content. Actively participate in group discussions, experiments, speeches and other activities to improve learning ability and expression ability. Organize class notes, finish homework in time, and consolidate what you have learned in class.
2, respect the teacher's teaching, don't interrupt others, and actively get along with classmates. Abide by school discipline and classroom rules, and maintain classroom order. When encountering difficulties and problems, seek help from teachers, classmates or parents in time so as to better understand and solve the problems.
3. Arrange the study time reasonably, allocate energy and attention reasonably, and avoid procrastination. Participate in extracurricular activities organized by the school, cultivate hobbies and improve overall quality. Keep a good habit of work and rest, eat reasonably and exercise moderately to ensure physical and mental health.
