As soon as Wu Bin woke up early in the morning, he suddenly received two freshly released task reminders.

Among them, winning the IPhO championship was originally his original goal, and he naturally had to complete it. However, for the college entrance examination, he really didn't want to go, but now that the task is out, Wu Bin must have to take the exam!

Let alone the rich 2000 experience, the main reason is that the extra rewards are too tempting. After all, those thinking bonuses make him feel like IQ +1, +1 every time.

Stretching, Wu Bin sat up and brought over the folder on the bedside. He has been reading this teaching material written by Su Yun since he returned to the dormitory yesterday. The content of it can be said to be similar to the previous teaching material very different.

In the last textbook, I mainly wrote about how to link games and teaching together, among which staged learning and appropriate rewards are the most important parts.

Now, the textbook in Wu Bin's hands is a real hard-core textbook, and its core purpose is to arouse students' interest in mathematics.

In fact, in elementary school textbooks, scenes in life are often used to attract children's interest and enthusiasm for learning, such as using matches to puzzle figures, exchanging whole money for small change, and other practical problems in life.

However, in high school mathematics is guided by logic and thinking, divorced from intuitive and concrete knowledge acquisition. This can easily make students defeated by boring, complex and abstract mathematics, or they can only learn without fun.

From this textbook, Su Yun used various methods to arouse students' interest.

One is to add a background story to the knowledge.

I believe that the Romance of the Three Kingdoms is boring to most people, but the Romance of the Three Kingdoms has made it the most topical era. After reading the Romance of the Three Kingdoms, there are many people who study the Romance of the Three Kingdoms. The reason is very Simple, that is the outstanding characters in Romance of the Three Kingdoms aroused their interest.

Mathematics can actually tell stories. For example, when learning functions, tell the history of the status of functions after the Bailey Klein movement, tell stories, talk about development, and then review the simple functions in junior high school step by step, and finally guide students to assimilate knowledge into it knowledge structure.

On this point, Wu Bin agrees very much. After reading Newton’s biography, he did have a very strong interest in the universe. Then a little bit of interest in learning about it is always a good start.

The second point is to let high school knowledge appear in life.

There is a saying, I believe most people have heard it, why are you so good at mathematics in high school, and you won’t need it for grocery shopping in the future.And this sentence has also been highly recognized.

Although some people later said that although high school knowledge cannot be used to buy groceries, it can decide where you buy groceries, but most people are still unconvinced, saying that it is the patent of the top students, and they can't learn the top. Yes, learning math is just a waste of time.

And Su Yun wanted to break this statement.

For example, when starting to teach exponential functions, you can ask a question first.

"Why can't I drink the water overnight?"

The answer is because of the growth of bacteria, and then the water that can pass through after a few hours is drinkable. How to measure it?Thus, the teaching of exponential function is introduced through the example of bacterial proliferation.

When talking about hyperboloids, you can also use the teaching aids hyperboloid gaps, so that students can intuitively see that hyperboloids are produced by hyperbolas around the axis of symmetry, and then give a few strengths, such as the famous Xiaomanyao in Guangzhou is also a hyperboloid, So are the cooling towers in the factory.

When talking about three-dimensional geometry, you can use computers to cultivate your interest. It is not necessary to have a lot of logical thinking, but it is not certain that some people may become interested in mathematics because of computers.

There is a passage that touched Wu Bin very much, that is, Su Yun wants to try the simplest algorithm to teach students to write a small game program or something they like. This may not be of great significance to mathematics education, but the significance of education is Let the children find something they are interested in and stick to it.

Mathematics and programming are naturally impossible to be irrelevant. If students can really make a small program by themselves, even if it is just to draw an ugly panda, or make a greedy snake move , which will undoubtedly be a huge learning motivation for them.

"She's really serious about it..." Wu Bin rubbed the folder, the more he read, the more he felt that the folder was heavy.

So at noon, Wu Bin excitedly went to see Su Yun and invited her to have lunch.

……

"I thought you weren't interested in anything but studies."

After the two of them sat down at the dining table, Su Yun smiled and teased Wu Bin, saying that she really didn't expect Wu Sanbin to give feedback on this textbook so quickly.

"Because the teacher's textbook is really interesting, so I can't wait to come and discuss it with you." Wu Bin said, taking a sip of soup, "I really look forward to seeing a class of students because of this There is a completely different understanding of mathematics because of textbooks, and its absolute value is promoted, no! It must be promoted!"

Hearing Wu Bin's exaggerated statement, Su Yun couldn't help showing a smile, "Actually, I didn't think too much about it, I just don't want when students ask me what's the use of learning this, but I can't answer the practicality, nor can I answer the questions." It’s not interesting enough, and this kind of teaching career makes me feel bad.”

"Hahaha, that's why I admire you very much. If you were any other teacher, you would definitely tell the students such things as why you ask so many questions. You know that learning this can give you more points in the exam."

"Okay, okay, don't say compliments first, I'm not showing you this to hear this, I just want to hear if you have any better suggestions."

"There are, there are suggestions, although they are not necessarily better, but you can use them as a reference, teacher."

"Oh? Then I'll be all ears." Su Yun propped her chin with her hands and looked at Wu Bin with a smile.
