First, correct examination of questions
Correct examination of questions is the first step and the key to the success of solving problems. Therefore, the examination of the questions must be careful and careful, so that "points" are not missed.
Examining the questions requires not missing the questions, reading the questions, understanding the meaning of the questions, understanding the conditions given by the questions and the questions to be answered. Different types of questions, different abilities, different problem-solving methods and strategies, and different scoring methods. For different types of questions, the emphasis is different.
In the examination of multiple-choice questions, it is necessary to find out whether you have chosen the right sentence or the wrong sentence, and what special methods are used to solve it. Fill in the blanks is an objective test. Without an intermediate problem-solving process, there is no process point. A little mistake is just like not doing it at all, and the consequences are very serious. When reviewing questions, we should pay attention to the knowledge points, methods and error-prone points of such questions. Only by understanding the conditions and implied information provided by the topic, associating the general methods of related problems, and finding and determining the specific methods and steps to solve the problem can we solve the problem.
Second, attach importance to mathematical concepts.
The concept of mathematics is the foundation of mathematics. Propositions in mathematics are all formed around concepts, and reasoning and proof in mathematics are also formed by propositions. Many students lose points because of vague concepts and insufficient understanding of concepts when reviewing questions.
In fact, the process of examining questions is to establish a clearer mathematical situation by clarifying the process of solving problems. Therefore, it is impossible to only pay attention to the conditions of specific data and ignore narrative language when reviewing questions. Some key words in narrative language play a decisive role in the mathematical situation described by the topic.
Third, cultivate observation ability.
Some technical problems have distinct characteristics. If these characteristics are discovered, it is easy to find the skills and methods to solve the problems. In the process of examination, paying attention to the characteristics of the topic can kill two birds with one stone, which not only reduces the difficulty of the topic, but also helps to explore the problem-solving skills. Faced with the direct or implied conditions in mathematics test questions, we should find out which ones are useful and which ones are not. Know what useless information to exclude and avoid interference.
Fourth, cultivate thinking ability.
To cultivate thinking habits in mathematics learning, we should not only understand the steps of solving problems, but also analyze the thinking of solving problems. The title of the math problem is very short, but it contains a lot of effective information. Pay attention to what can be judged according to the conditions given in the topic.
In mathematics learning, the training of multi-solution, multi-thinking and changeable problems plays an important role in cultivating the flexibility and profundity of thinking. The training of multi-solution and multi-thinking is inseparable from the careful examination and analysis of the questions. It can be said that without strict examination, there will be no multiple solutions to one question, and it is impossible to carry out effective multi-thinking and changeable questions. Students need to make clear the connection and difference between knowledge and mathematics through comparison.
Scientific examination methods are necessary for every student. Only by conducting effective exams and cultivating good exam habits can we greatly improve students' ability to solve mathematical problems and improve our academic performance.
