As soon as Wu Bin woke up early in the morning, he suddenly received two fresh mission reminders.

Among them, winning the IPhO championship was his original goal, and he had to achieve it naturally. However, he did not want to take the college entrance examination. But now that the task is out, Wu Bin must take the exam!

Not to mention the generous 2000 experience points, the main reason is that the additional rewards are too tempting. After all, those thinking bonuses make him feel as if his IQ is +1 or +1 every time.

Stretching, Wu Bin sat up and took the folder from the bedside. He had been reading the teaching material written by Su Yun since he returned to the dormitory yesterday. The content can be said to be the same as the last teaching material. Very different.

In the last textbook, I mainly wrote about how to connect games and teaching, of which staged learning and just the right rewards are the most important parts.

The textbook now in Wu Bin's hands is a truly hard-core textbook. Its core purpose is to arouse students' interest in mathematics.

In fact, primary school textbooks often use real-life scenes to attract children's interest and enthusiasm for learning, such as using matchsticks to make puzzles, exchanging whole coins for 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 want to study the Romance of the Three Kingdoms. There are many reasons for this. Simply, it was the outstanding characters in the Romance of the Three Kingdoms that aroused their interest.

In fact, mathematics can also tell stories. For example, when learning functions, we should tell the history of the status of functions after the Bailey-Klein movement, tell stories, talk about the 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 agreed very much. After reading Newton's biography, he indeed became very interested in the universe. Although for ordinary students, this is not enough to make him fall in love with mathematics at once, but as long as he has So a little bit of interest in getting to know it is always a good start.

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

There is a saying that I believe most people have heard: Why are you so good at math in high school? You won’t need it when shopping for groceries in the future. And this sentence has been highly recognized.

Although some people later responded by saying that although high school knowledge cannot be used to buy groceries, it can determine where you buy groceries, most people are still unconvinced, saying that it is the exclusive preserve of top academics, and they cannot learn from the top. Yes, learning math is just a waste of time.

And Su Yun wants to break this statement.

For example, when you start teaching exponential functions, you can first ask a question.

"Why can't you drink water overnight?"

The answer is because there are bacteria growing and then passing through. How many hours has passed before the water is drinkable? How should we measure this? Thus, the teaching of exponential functions is introduced through the example of bacterial proliferation.

When talking about hyperboloids, you can also use the teaching aid hyperbolus to let students intuitively see that hyperboloids are produced around the axis of symmetry. Then, let’s give some examples. For example, the famous Xiaomanyao in Guangzhou is also a hyperboloid. So are the factory cooling towers.

When teaching solid geometry, you can use computers to cultivate interest. It does not necessarily require a lot of logical thinking, but it is not certain that some people may become interested in mathematics because of computers.

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

Mathematics and programming are naturally not unrelated. If students can really make a small program by themselves, even if they just draw an ugly panda, or make a greedy snake move, , which will undoubtedly be a huge learning motivation for them.

"She is really serious about what she does..." Wu Bin rubbed the folder. The more contents he read, the heavier he felt the folder became.

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

…

"I thought you weren't interested in anything other than studying."

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

"Teacher, this textbook of yours is really interesting, so I can't wait to discuss it with you." Wu Bin said, taking a sip of soup, "I'm really looking forward to seeing a class of students who are interested in this textbook." The textbooks have given me a completely different understanding of mathematics. It is definitely worthy of being promoted, no! It must be promoted!"

Listening to Wu Bin's somewhat exaggerated statement, Su Yun couldn't help but smile, "Actually, I didn't think about it that much. I just don't want when students ask me what's the use of learning this, I can't answer the practicality or the practicality." I can’t say it’s interesting, and I would feel terrible about a teaching career like this.”

"Hahaha, so I admire you very much. If it were any other teacher, he would definitely tell the students something like "Why are you asking so many questions? You know that learning this can help you score more points in the exam."

"Okay, okay, let's stop saying compliments. I'm not showing this to you just to hear this. I just want to hear what better suggestions you have."

"Yes, yes, there are suggestions. Although they are not necessarily better, teacher, you can use them as a reference."

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