First of all, establish a correct learning attitude:
Who doesn't want to be a good student, but if you want to be a really good student, the first thing is to study hard, that is, to dare to endure hardships, cherish time and study tirelessly. Establish confidence, firmly believe that you can learn any course well, firmly believe in the "law of conservation of energy transformation", and firmly believe that you should get several times if you pay a few times.
There are eight links in learning: planning → preview before class → concentrate in class → review in time → independent homework → problem solving → systematic summary → extracurricular learning. The most important thing here is: concentrate in class → review in time → work independently → solve problems → summarize systematically.
Third, some specific learning methods of junior high school physics.
(1) pay attention to the three basics. Basic concepts should be clear, basic laws should be familiar, and basic methods should be skilled. Give an example about the basic concept. For example, speed indicates the distance traveled by an object in unit time: v = s/t, and for the basic law, for example, the calculation formula of average speed is also v = s/t, so let's talk about the basic method. When learning junior high school physics problems, sometimes we should pay attention to choosing "objects". For example, when solving problems with ohm's law, it is necessary to make clear whether ohm's law applies to the whole circuit, that is, the whole circuit, or to a certain resistor, that is, a single resistor.
(2) Do the problem independently. Do some problems independently with good quality and quantity (meaning not relying on others). There must be a certain number of topics, not too few, but also a certain quality, that is to say, there must be some difficulty. Anyone who studies mathematics and physics can't learn this level well. Solving problems independently may sometimes be slow, sometimes you have to take detours, and sometimes you can't even solve them, but these are normal and the only way for any beginner to succeed.
(3) Physical process. To clarify the physical process, there must be hidden dangers in solving problems if the physical process is not clear. No matter how difficult the topic is, try to draw as much as possible, some can draw sketches, and some need to draw accurate pictures, using compasses, triangles, protractors and so on. To represent geometric relationships. Drawing can turn abstract thinking into image thinking and master physical process more accurately. With this diagram, we can make state analysis and dynamic analysis. State analysis is fixed, dead and discontinuous, while dynamic analysis is alive and continuous, especially when solving circuit problems. Without drawing a circuit diagram, it is difficult to know whether the resistors are connected in series or in parallel.
(4) attending classes. Listen carefully in class and don't think or think as little as possible. Don't be self-righteous, learn from the teacher modestly. Don't give up listening just because the teacher speaks simply. If this happens, it can be regarded as review and consolidation. Try to be consistent and synchronized with the teacher, and you can't do it yourself, otherwise it will be self-study. After getting started, with a certain foundation, you are allowed to have your own activity space, that is, you are allowed to have something of your own. The more you learn, the more things you have.
(5) notebook. Class is mainly based on listening, and there are notebooks, and some things should be written down. Knowledge structure, good problem-solving methods, good examples, places you don't understand, etc. Should be recorded. After class, you should organize your notes. On the one hand, you should "digest" and on the other hand, you should supplement your notes. Notebook is not only to remember what the teacher said in class, but also to make some reading notes. Good problems found in homework and good solutions should also be recorded in a notebook, which is what students often call a "good problem book". Hard-won notebooks should be numbered, studied later and kept for life.
(6) learn from others. We should learn from others, from our classmates, from people around us and see how others learn. We should often have "academic" exchanges with them, teach each other, learn from each other and improve together. We must never be self-righteous. Cann't be conservative Tell others if you have a good method, so that others will tell you that you have a good method. You should have some good friends in your study.
(7) knowledge structure. We should attach importance to the knowledge structure, master it systematically, and systematize scattered knowledge. From the whole knowledge structure of physics to the knowledge structure of mechanics, even to chapters.
(8) mathematics. The calculation of physics depends on mathematics, which is too important for learning physics. Physics is difficult to do without mathematics as a calculation tool. In the physics department of the university, mathematics and physics are equally important. To learn mathematics well, we must make good use of this powerful tool.
The above has briefly talked about some learning methods. More specific and effective learning methods need to be explored and summarized by themselves in the learning process, and others' methods need to be tested by themselves before they can become their own things.
I believe that after some efforts, you will certainly reap fruitful results. Victory always belongs to those who can persist to the end!
