On the afternoon of June 18, 2023, the mathematics subject of Shanghai senior high school entrance examination was successfully concluded. The test paper is stable in structure, type and quantity. The overall difficulty of the test paper is above average, highlighting the examination of basic knowledge, basic skills and basic mathematical thinking methods, and paying attention to the examination of problem analysis and problem solving ability. Some of the test questions are innovative, reflecting the inquiry, openness and comprehensiveness.
The examination paper pays attention to the connection between mathematical knowledge and real life. Through the ingenious situation setting, this paper examines the analysis and solving ability of candidates in real life situations, and guides candidates to observe the world with mathematical eyes and think about the real world with mathematical thinking.
Methods of learning junior high school mathematics well
1, activity preview
Preview is a general understanding of the relevant knowledge of the course to be studied, which is convenient for you to easily keep up with the teacher's teaching chapters in class.
Doing so not only makes passive lectures become active lectures, but also strengthens the effect of lectures and improves learning efficiency. Have a general understanding of the knowledge learned in the next lesson, such as texts, laws, formulas and so on.
2. Active thinking
Most students just listen mechanically in the process of listening to the class and can't think on their own initiative. In this way, when facing the questions in the exam, they will have no way to start and don't know how to apply what they have learned to answer them.
The main reason is that I don't think in class. In addition to following the teacher's thinking, we should also think more about why we should define it like this, and what are the benefits of this thinking. Taking the initiative to think like this can not only make us more serious in class, but also stimulate our interest in mathematics knowledge.
3. Broaden the thinking of solving problems
When solving mathematical problems, we should try our best to draw inferences from others and be diligent in thinking. After solving a problem, we should think about whether there are other simpler methods, so that we can broaden our thinking and have more choices in the process of doing problems in the future. Of course, it is necessary to be targeted, not all problems have multiple methods, and it is enough to solve them quickly with what you have learned so far.
There must be a book wrong.
Wrong questions can record your own knowledge shortcomings at any time, which is helpful to strengthen the knowledge system and improve learning efficiency. Many schoolmasters got high marks because they used the wrong textbooks on their own initiative.
5. Finish your homework independently
Nowadays, many students use some applications to help them finish their homework. They can find the answer by looking for photos, or copy other students' homework. This can be divided into two situations. One is for quick photos and speed. If you do this often, you will form a bad habit of reviewing questions, which is easy to be clear at a glance and careless.
Another is for convenience, which will lead to students' fear of trouble. Once the topic is a little difficult, they will start to get upset and confused. So everyone must form the good habit of finishing homework independently.
