Improvement: Many students like the joy of overcoming problems, so they show the spirit of not dying until the Yellow River, sometimes spending a class time to overcome a problem, and have a sense of achievement.
The problem is that the efficiency of tackling one problem in one class is really too low. A master learner would never do that.
Remember: never spend a single lesson solving a difficult problem, which is a major cause of inefficiency. If you use one class to solve a problem, what should you do with other topics, do you have enough time, and more importantly, do you really gain a lot from this topic?
Expert's strategy: If a question still can't be solved after 10 minutes, then just look at the answer or wait for the teacher to explain. Because, being able to do this question, and being able to draw inferences from one another, and being able to make a full summary is the most important purpose.
After reading the answer, or listening to the explanation, you must spend more time to summarize: why did I not answer this question, the breakthrough is in**, why didn't I find it, which key words trigger the solution idea, how should I establish conditioning, so that I can see these vocabulary information again in the future and quickly find the relevant breakthrough. Remember, that's the most important job.
The inductive summary of mathematics is too important. Top students, they spend 5 minutes doing a problem, and then they will spend 10-15 minutes to make an inductive summary and write a solution note.
Inductive summary is actually the problem solving association, that is, writing the solution notes, and summarizing the "conditioned reflex". In order to improve the sensitivity to key words, we can quickly establish conditioned reflexes and find a breakthrough in solving problems through key words, which is the so-called problem-solving association. This is a compulsory course for math masters.
Summarizing and summarizing is all conditioned reflexes, that is, what I see, I have to associate with something, and then break through this problem in one fell swoop. For example, when I see the word "integer", I think of mathematical induction. 0
