When I was in elementary school, my math teacher was required to memorize concepts and definitions from textbooks. What I still remember is a classroom inspection, first ordered the squad leader to get up and memorize, and the squad leader recited it fluently without emotion. The second one is to point me to get up and memorize, I said while thinking about it, and added a word or two to "memorize" it.
At this time, the teacher asked the students who I memorized well with the class leader, and the students all said that the class leader was because there was a difference between what I memorized and the textbook.
The math teacher said: She thinks I said it better, because I didn't memorize it at all, I completely according to my own understanding, repeated the definition, and the class leader obviously memorized it seriously.
Indeed, I admit that I did not memorize the definition of mathematics as I did in Chinese, and obviously, the class leader was not convinced. This is probably the only time I have been praised for not completing my homework as required by my teacher.
Now, if you asked me to say this, I don't think it's right.
Let's say it's not right first, after all, the squad leader memorized it seriously, and he can't be judged that he didn't understand because he memorized it word for word. This may also be the reason why the squad leader was not convinced at that time.
Besides, the math teacher may want to emphasize to the students through this incident that the concepts and properties of mathematics must be memorized comprehensibly, rather than rote memorization.
Therefore, mathematical concepts are not something that many parents do not need to memorize, but they are more demanding than liberal arts, and they need to be memorized word for word after understanding.
I have been teaching mathematics for many years, and I believe that the definitions, concepts, and theorems of junior high school mathematics need to be memorized, but not by rote, but by memorization on the basis of understanding. Mathematics is a logically rigorous discipline, and its definitions, concepts, and theorems are all derived through rigorous derivation and proof, and have an intrinsic logical connection. Therefore, students should gradually master these basic knowledge through repeated practice and application on the basis of understanding.
Memorizing mathematical definitions, concepts, theorems can help students better understand the nature and intrinsic connections of mathematical knowledge, so that they can better apply this knowledge to solve problems. At the same time, these basic knowledge are also the basis for subsequent learning, which plays an important role in improving students' mathematical performance and mathematical thinking ability.
However, rote memorization is not an effective method of learning. In the process of memorization, students should focus on comprehension, and through repeated practice and application, they should internalize this knowledge into their own abilities. At the same time, students should also pay attention to induction and summarization, systematize what they have learned, and form their own knowledge system.
In addition, teachers should also focus on guiding and inspiring students, and help students better understand and master these basic knowledge through lively and interesting teaching methods. At the same time, teachers should also pay attention to cultivating students' mathematical thinking ability and problem-solving ability, so that students can get all-round development in the process of mathematics learning.
To sum up, junior high school mathematics definitions, concepts, and theorems need to be memorized, but they should be memorized on the basis of understanding, and at the same time, they should pay attention to induction and summarization to form their own knowledge system. Students and teachers should work together to help students better understand and master these fundamentals through engaging and engaging teaching methods.
