In the third grade, students should learn a new course-chemistry. If students want to learn chemistry well in less than a year, they should not only attach importance to it, but also master scientific learning methods.

A, diligent in preview, good at listening to lectures and taking notes.

You must preview before class. When previewing, in addition to reading the new lesson carefully, we should also mark out what we don't understand and try to do some exercises in the textbook. In this way, with problems and difficulties, the efficiency of class will be greatly improved.

There are many contents in junior middle school chemistry, and the teacher focuses on the key contents when giving lectures. Therefore, everyone should listen carefully and take notes carefully, which is not only conducive to reviewing after class, grasping the key points, but also effectively preventing the class from being distracted. But you must pay attention to the method when taking notes. On the basis of listening to the teacher clearly, we should remember the key points, difficulties, doubts and contents that are not in the textbook.

Second, review frequently and remember more.

After class, you should review in time and do your homework carefully, which is an important link to learn chemistry well. Review can be done after class, after week, unit review, chapter review and comprehensive review. Review methods include retelling, dictation, contact, etc. Only by reviewing many times can we firmly grasp the knowledge.

There are 50 or 60 basic concepts and principles in the current junior middle school chemistry textbooks, which require more than 20 element symbols, as well as a lot of knowledge such as chemical formulas and chemical equations. These contents need to be memorized on the basis of understanding. Most of them are the basis of learning chemistry. If you can't remember them, it will be difficult for you to walk in the "chemical kingdom".

Third, read the textbook thoroughly and connect with reality.

Taking textbooks as the main line, carefully understanding textbooks is the basis of learning chemistry well. Therefore, students must be good at reading textbooks, preview before class, read carefully after class and read frequently. We should not only pay attention to the main content, but also ignore the fine print, some charts and selected content, because these contents will help deepen our understanding of the main content and broaden our knowledge. When reading carefully after class, you should remember while reading, so as to solve all unresolved problems in preview and lecture. Regular selective reading refers to selective reading of those important or difficult to fully understand. At the same time, through various forms of reading, it is also helpful to improve self-study ability.

The content of junior middle school chemistry is closely related to life and production. This requires us to get in touch with the reality of production and life as much as possible while studying chemistry, and discover and appreciate chemistry from the life around us, so that the more we learn, the more interested we are, the more we want to learn, and the more we learn, the more we love learning.

Fourth, attach importance to experiments and cultivate interest.

Chemistry is a subject based on experiments. Experiments can not only stimulate our interest in learning, but also be very important for us to form chemical concepts, understand and consolidate knowledge, train experimental skills, cultivate observation and practical ability, improve thinking and solve practical problems. This requires us to carefully observe the teacher's demonstration experiment, and make clear and memorize the instruments, drugs, devices, experimental principles, steps, phenomena and precautions used in the experiment. At the same time, do a good job in students' experiments, interesting experiments and small family experiments, and actively participate in extracurricular activities in chemistry, such as visits, lectures and chemistry games. Actively cultivate their interest in learning chemistry.
