For the first-year students to learn mathematics and get high scores, they need to be able to review questions with speed and accuracy
Many first-year students lose a lot of points when solving math problems due to unclear review. Getting good grades in math is critical to triage questions. As soon as some students get the test paper, they will answer in a hurry, for fear of losing points if they do not finish it. As a result, they often make mistakes in their busy schedule, and they are not accurate. not reach.
The correct examination
Correctly reviewing questions is the first step and the key to successful problem solving. Therefore, the examination of the questions must be meticulous and careful, so as to ensure that the "points" are not missed.
Examination requires no omission of questions, seeing the question accurately, clarifying the meaning of the question, understanding the conditions given by the question and the questions required to be answered. Different question types examine different abilities, have different problem-solving methods and strategies, and have different scoring methods.
For multiple-choice questions, it is necessary to find out whether to choose a correct statement or a wrong statement, and what special method to use to solve the problem. Fill-in-the-blank questions are objective questions. There is no intermediate problem-solving process, and there is no process points. A little error will result in the same result as not doing it at all, "serious consequences". When reviewing the questions, pay attention to the knowledge points, methods and error-prone points of the question examination. Only by understanding the conditions and implicit information provided by the question, associating the general method of related question types, and finding and determining the specific problem-solving methods and steps, the problem can be solved.
Second, pay attention to mathematical concepts
Mathematical concepts are the foundation of the mathematical discipline. Propositions in mathematics are formed around concepts, and reasoning and proof in mathematics are formed by propositions. Many students lose points due to vague concepts and insufficient understanding of concepts when reviewing questions.
The process of reviewing questions is actually the process of establishing a clearer mathematical situation by clarifying the problem-solving process. Therefore, it is not enough to focus only on the conditions of specific data and ignore the narrative language when reviewing questions. Some key words in the narrative language play a decisive role in the mathematical situation described by the item.
- Cultivate the ability of observation
For some technical topics, their characteristics are more distinct and prominent. If these characteristics are found, it is easy to find the skills and methods to solve the problem. In the process of reviewing questions, pay attention to the characteristics of the questions, which can kill two birds with one stone, which not only reduces the difficulty of the questions, but also facilitates the exploration of problem-solving skills. Faced with direct or implicit conditions in math test questions, figure out what works and what doesn't. Know what useless information to exclude and avoid distractions.
- Cultivate thinking ability
In mathematics learning, it is necessary to develop the habit of thinking well, not only to understand the problem-solving steps of a problem, but also to analyze the problem-solving ideas. The topics of mathematics questions are relatively short, but they contain a lot of effective information. Pay attention to the conditions given by the questions to determine what content can be determined.
In mathematics learning, the training of multiple solutions for one question, multiple thinking for one question, and multiple changes for one question plays an important role in cultivating thinking behaviors such as flexibility and depth of thinking. The practice of changing one question is inseparable from the rigorous and meticulous examination and analysis of the question. It can be said that without a rigorous examination, there will be no multiple solutions to one question, and it is impossible to effectively think more about one question and change one question. . Students need to understand the connection and difference between knowledge and mathematics through comparison.
Scientific examination methods are necessary for every student. Only by conducting effective examination and cultivating good examination habits can we greatly improve students' ability to solve mathematical problems and improve our academic performance.
