Three steps of self-study of physics and chemistry. The first step is to frame the whole, the second step is to learn in chapters, and the third step is to identify and flag problems. [Than heart] [Than heart]
During the winter vacation, parents want their children to prepare their textbooks in advance. The requirements are also very simple, as long as the content in the textbook is smoothed from beginning to end, there is a preliminary impression and understanding. A lot of my classmates do the same, right?
What I want to say today is that in fact, such a preview is invalid, why is it invalid? Whether it is reviewing or pre-studying in advance, it must have depth, if it is just a dragonfly bit of water to browse again, sloppy to see again, I personally think there is almost no effect.
Since you want to learn, you must have depth, if you can't learn a certain depth, then simply don't study down, you must think about it very thoroughly. The process of real exams, or selective exams, will definitely make a fuss about difficult problems, and if they all take general questions, then who goes to a prestigious school? Who will fall behind?
Therefore, independent preparation, if it does not achieve a medium difficulty or above, is actually meaningless.
When most children prepare, they read the book again for a model.
What is the purpose of self-directed preparation? Find problems and take them to lectures and solve problems, and through self-study, understand the new knowledge points that are about to be learned. Find out if you can't understand the problems that you can't understand, if you use the past knowledge reserves, you can understand and must know the new knowledge points, you can also consult the information to compare, you can also listen to how the teacher understands, see what is the difference?
The following takes junior high school chemistry as an example and shares with you the three steps of independent prep.
The first step is to find a real exam paper for chemistry in the middle school exam, why do you choose the real exam question? Because it's the result of a lot of hard work by top experts, I'm sure you won't do it, because you haven't learned it. Then read through the textbook to find out where the relevant knowledge points are? The purpose is not to let you do the exam questions, but to understand the overall framework of the discipline of chemistry, to complete this matter about half a day is enough, after completion you will basically understand, the original junior high school chemistry is to learn these contents.
The second step is to start the chapter study. The method of chapter learning is similar to the first step, which is also to first find a chapter test paper, open the book to find and understand the important knowledge points of the chapter, and then look back at the textbook, understand the concepts, understand the example questions, and do the right exercises. Next, I started the closed-book exam, and after the exam, I returned to the textbook and returned to the basic concepts.
The third step, find out what you can't understand, can't learn the problem, write it down to find relevant information, or stay until after the start of the school to listen to the teacher's explanation, with the problem to listen to the class, compared to you ignorant to listen to the class, the learning efficiency will be much higher, after the overall learning with the mind map, sort out the framework diagram of the junior high school chemistry discipline, this is the complete independent preparation process. It is the basic skill of learning, and if you can really do this, you are not far from learning to be a bully.
The first step is to frame the whole, the second step is to learn in chapters, and the third step is to identify and flag problems. Have you learned? Remember to like the collection! [Rose] [Rose]
