I put this question at the end of the school's seminar on mathematics teachers' literacy, and wanted to see how they answered this question as mathematics teachers.
The teachers' answers are as follows:
1) Watermelon 1: You won't know if it is ripe until you cut it.
Watermelon 2: You don't know how sweet it is until you open it.
2) crabs. (1) It takes patience to eat crabs and patience to learn math. (2) If you want to eat crab meat, you must use your head. Cooked meat is not complete, so is learning mathematics. (3) People who love and can eat crabs will understand its value. Even if there is a little trouble in the process of eating. In the same way, people who like mathematics and people who know mathematics will know the beauty of mathematics.
3) Rice (flour)-value. (1) I eat it every day. Just like rice (flour), I encounter it every day in mathematics. Numbers, symbols and so on are all related to mathematics. (2) Since childhood, rice (flour) has provided us with nutrition, and mathematics has also enriched our knowledge and helped us solve some problems.
4) Roast whole sheep. It tastes heavy and delicious! You can also bake it for fun! Can also be shared by many people! General holidays, holidays, parties will eat! Just relax。
5) Durian 1: Delicate and tasty.
Durian 2: I hate it. I like it. It's very nutritious. When you are hungry, you are comfortable and energetic.
Durian 3: the appearance and smell are daunting, and you can only find delicious food after accepting it.
6) Chocolate: You don't know what it tastes like until you taste it.
7) Olive fruit: astringent and sweet.
8) Steak: The cooking degree of steak is different, and people who dare to explore and challenge the unknown will have different tastes. Fried steak is also an exquisite lifestyle, just like mathematics requires bold attempts and careful analysis. It is not difficult to say difficult, and it is not difficult to say simple.
9) Green apples: Some are sweet, but very sour. Mathematics is both interesting and challenging.
10) white rice: although it is very common, it is indispensable in life.
1 1) coffee: there is bitterness in the fragrance and sweetness in the bitterness.
12) Walnut: The surface is hard and difficult to open. But it chews well after being broken.
13) Pomegranate: Simple in appearance and rich in content.
14) hickory: I enjoyed the peeling process very much, and finally I peeled it open to eat.
15) Stinky tofu: Smells stinky and tastes fragrant. As long as you don't give up, you can still feel the beauty of mathematics.
16) water: because water is everywhere, it may not be important, but once it is lost, it will lose a lifetime, just like mathematics is everywhere, unimportant but essential.
17) Salt: Mathematics is indispensable in life, just as people cannot do without salt.
18) Pork sausage rice noodles, red soup: straight, slippery and delicious. I can't get in the door, I can only feel spicy, and my tears are hot.
Ladies and gentlemen, which answer do you like best?
The reasons should be different, there is no standard answer, but they are all strongly personal.
The same watermelon is interpreted from different angles, one is from the difficulty of mathematics learning, the other is from the taste, two completely different people. But they must be "opened" before they can be appreciated, that is, "introduced" before they can know.
Analytical mathematics is the teacher of "crab". He must be proficient in mathematics. At the same time, he must be a patient person with strong logical thinking and good at analyzing problems. Blue personality. Of course, his description focuses on "eating crabs", that is, "how to learn mathematics", which turns a static problem into a dynamic one. Similarly, there are "walnuts" and "pecans".
It is more described from the role of mathematics: essential and valuable. Such as rice, water and salt.
There is also a description from the feeling that mathematics gives people the feeling of "bitter", "difficult", "astringent" and "heavy taste", which shows that learning mathematics is "difficult"
There are also mathematical descriptions, such as pomegranate. It looks dull, but it is all-encompassing.
Throughout these descriptions, it still embodies the following characteristics of mathematics:
1. Highly abstract: The abstraction of mathematics is different from that of other disciplines in object and degree. Mathematics is established and developed in an abstract way. Because of abstraction, it will become a bit difficult to understand, especially the entry is difficult and full of challenges.
2. Strict logic: Mathematics has strict logic, and any mathematical conclusion must be strictly proved by logical reasoning before it can be recognized. Strict logic is not unique to mathematics. Because of strict logic, you will find the truth, goodness and beauty of mathematics after getting started.
3. Wide applicability: As a tool or means, mathematics is applied to almost any science and technology and all social fields. This is everyone's knowledge.
As a math teacher, we have a lot of feelings. When facing students, we can make students close to math in a targeted way.
