Li Ke has a complete set of textbooks in his hands, but not all subjects are suitable for this era, the steps are too big and easy to pull eggs, Li Ke naturally can't make such a mistake, he has lived in this world for eight years.

For example, in terms of language, Li Ke revised the least, and the Chinese textbooks were all in accordance with the teaching progress of the Tang Dynasty, including the textbooks are also the Four Books and Five Classics, etc., the only difference is that the Four Books and Five Classics that Li Ke took out were all annotated by Confucianism in this era, and then Li Ke added punctuation marks to break the sentence.

In addition, Li Ke added Chinese character pinyin.

The twenty-six letters are combined with the Chinese pinyin scheme for Mongolian education, which is much easier to remember than the ancient phonetic scheme, because these things have been tested for a long time in later generations, not to mention that the standard English alphabet of this era was not born, which was invented after Li Ke observed the "ancient Greek characters".

Compared with the ancient phonetic method, Pinyin has the advantage of fewer symbols, only the basic twenty-six letters, and phonemes, basically each letter or combination of letters has only one pronunciation, so it is not easy to be confused.

It is easier to spread and easier to teach, which means that even a child who has just learned all the pinyin can teach the pronunciation of the word to the adults in his own family.

Another advantage is that after learning pinyin, you can write simply, even if the text can't, you can use pinyin instead, I believe that many children have done similar things when they were children.

This has a huge advantage for the literacy work that Datang may carry out in the future, and there is also the fact that these pinyin later generations have adapted a variety of children's songs, which are also catchy to learn. In addition, after adding pinyin, it is also helpful for subsequent mathematics teaching.

In addition, Li Ke has not changed much in terms of language.

Mathematics is the biggest change, and there are many ancient mathematical classics in the Tang Dynasty, and even many mathematical theories are very advanced.

But there are no step-by-step learning textbooks, especially few mathematics textbooks suitable for starting from Mengxue, but Li Ke took out mathematics textbooks from elementary school to high school.

However, Li Ke temporarily got the textbooks of junior high school, algebra and geometry, and the mathematics books of junior high school are enough to solve almost all the math problems of Datang.

The follow-up is more advanced, and I am afraid that it is suitable for university to study in Datang.

Geography and biology also started from Mongolian studies, but unlike later generations, geography and biology here are really very shallow, such as geography, only the most basic introduction to mountains and rivers, southeast, northwest and so on. And the creatures are almost like this, that is, the plants, animals, etc. are preliminarily classified, that is, they have a concept.

The basic physics and chemistry are even more basic, mainly some simple physical and chemical phenomena in reality, as well as scientific experiments and so on.

The ideological and political aspects are simpler, mainly to strengthen patriotic and other aspects of education, which is impossible to come up with many advanced ideological and political contents in later generations.

"How do you feel?" Li Ke looked at them and asked.

"It's so tiring to go to school." Baling spoke directly.

"Hahaha." Li Ke couldn't help but laugh, tired? You guys are nothing, the things that later generations of high school students learn are too advanced in this era, and it is impossible to take them out, at most, they will learn the knowledge of junior high school, and the subsequent high school knowledge will be regarded as advanced content.

In the future, I will basically talk about it in college, and I may not even be able to teach a lot of knowledge in high school.

But if you're tired, how can children play every day? I didn't play like this when I was a kid, and I'm not happy with you guys playing like this.

"But I'm tired, but I always feel ...... It turns out that we still don't know so many things before, and after learning this, we suddenly find that there are many things in this world that we don't understand. Yu Zhang said with emotion.

"Well, that's good, you are all princes and princesses, and this knowledge naturally starts with you." Li Ke said seriously.

In fact, what Yuzhang didn't know was that there were many schools like this in Yuelai Commercial Bank, but they were not for training anything else, but for training teachers.

In addition, Li Ke's current craftsman department has begun to learn mathematics, physics and chemistry.

Because they're going to continue to develop, they're going to have to learn these things.

"Well, but third brother, you better pay attention, I'm afraid that Aya will beat you up." Yu Zhang suddenly lowered his voice and leaned into Li Ke's ear and said.

"Why?" Li Ke was a little confused.

"A few of them." Yu Zhangchong next to Li Zhi and them snorted. "These people like to run into the barracks now, and ...... They don't know who to learn from and often swear. ”

Li Ke: "......"

"I know, the third brother will give you a good thing another day." Li Ke said in a low voice.

"Hey, hey." Yu Zhang smiled secretly.

"Let's go, let's go to the house to see the queen mother and them, and let the third brother talk to them." Changle smiled, beckoned these sisters and led them to the Bauhinia Tower.

There was only a group of princes left at the scene.

Today, except for Li Chengqian and a few very young people, it can be said that he is the most complete.

"How? What do you guys think? Li Ke asked with a smile, to be honest, these are a little surprising to Li Ke today, and the biggest changes here are actually Li Su and Li You.

These two had a common problem before, that is, they didn't learn well, in history, they can be said to be the most unsuccessful among Li Shimin's many princes, but now the biggest change is actually the two of them.

Li Yu was also brought to the Western Regions by Li Ke for a year of rectification, and he felt it even more deeply, but Li You's change made Li Ke not expect it.

Just now, the two of them have been standing next to each other, very calm, and the posture of standing there is also quite a military momentum.

It can only be said that a hot-blooded young man like Li You, although he really didn't learn well before, he is easily influenced, his head is simple, his brain is full of righteousness, and throwing it into the barracks can indeed completely change.

"I want to go to the army in the future, like you, third brother, to expand the territory of Datang and make contributions." Li You said seriously.

Li Ke smiled and nodded, he could see that no one taught this, if Li You's biological mother or something was there, it would be absolutely impossible for him to say this.

Because in addition to the fact that the founding emperor may have the prince lead the army to fight, in the prosperity of a dynasty, it is rare for the prince to command the army, and the thing of military power is easy to cause a lot of ideas.

But Li You said it very simply, obviously this was his own inner thoughts.

After Li You said it, Li Tai next to him glanced at it.

"Yes, but the army is different from other places, the battlefield can make achievements, but it can also be shrouded in horse leather, and the swords and arrows on the battlefield will not detour just because you are the prince." Li Ke said with a serious face.

"I know, third brother." Li You nodded seriously.

"Okay, after you finish studying, you still want to go, and the third brother will send you there." Li Ke said seriously.
