Su Han has more than 30 years' teaching experience, from being an ordinary teacher at first to becoming the head teacher of a math class with excellent teaching results. In Su Han's view, mathematics is a basic subject, but it is also a course that is relatively easy to get points as long as you understand the most important basic principles. In Su Han's view, the so-called "poor students" can also get full marks. If you want to lose less points in the exam, you must start from three aspects.
1, a key word in the legal definition
Su Han pointed out that when many people recite the definition of law, they usually ignore the small details that are often regarded as traps when they are published. For example, when solving a function and an answer, whether the answer is equal to 0 is a point that is often considered. So many people lose points not because the function domain is wrong, but because they have not removed the incorrect answer.
When studying, Su Han suggested that the key words in this law and definition can be marked, such as positive numbers, spacing and parallel lines. These are some small details that may lead to test sites, and these are the hardest hit areas that cause test scores to be lost. Therefore, when learning, marking this key can better assist understanding and reduce mistakes.
2. Learn from reciting.
Su Han believes that common sense, which is sometimes regarded as cleverness, actually revolves around a lot of reflective learning, such as repeated recitation and a lot of brush exercises. For students with poor foundation, Su Han never suggested one step at a time. No matter how talented people are, they need to complete and accumulate step by step. Therefore, reciting at the beginning is a very effective learning method.
Su Han thinks that memorizing the main points of knowledge, memorizing questions, memorizing answers and memorizing the steps of solving problems can be accumulated. When studying, you must learn by rote and try to figure it out. Only in this way can you lay a solid foundation for future improvement.
3. Summarize after each exam
Su Han thinks that one of the differences between math class and other subjects is that there are many kinds of exams and papers, but in order to give full play to this topic as much as possible, it is very important to summarize the exams after each exam.
Su Han suggested that we should do a good job in summing up the wrong questions, and at the same time, we should study repeatedly to figure out the wrong questions, so as to give full play to our wrong questions and make more achievements in the next exam.
