That night, Lin Yan finished practicing and began to think about what to teach Shi Zhi and the others.
Everything has to start from the most basic level. Mathematics is easy to teach. They have already mastered the basic algorithms. Just increase the difficulty a little and start learning systematically.
The difficult part is physics and chemistry. Starting from scratch, what should we teach?
"Pang Bao, do you have any basic teaching materials?"
Fat Bao: "What basic teaching materials do you need?"
Lin Yan rolled her eyes. It was possible to ask such a question. She could still make a choice. She said, "I want an enlightenment textbook for people with zero basic knowledge of physics and chemistry."
Fat Bao: "There are basic chemistry and basic physics, which need to be exchanged with your contribution points. Each book has 5 contribution points."
"Really? Do you have basic mathematics?" Lin Yan asked hurriedly. It only had five contribution points, so it was completely affordable.
Fat Bao: "Yes."
Lin Yan felt happy, "Where will the exchanged books be?"
Fat Bao: "The exchange is for a virtual book, which is stored in the core of the Science and Technology Museum. You can view it on the display screen at any time if you need it."
"Will it always be there?"
Fat Bao: "Always there, forever."
Lin Yan immediately and generously spent 15 contribution points to redeem basic textbooks on mathematics, physics and chemistry. Then, she saw that there was an additional icon in the display area of the black crystal ball, which were the three books she had exchanged. .
Her mind moved, and three books were displayed on the big screen very clearly.
"Pang Bao, open basic physics."
Fat Bao: "Okay, please take a look."
Lin Yan browsed through it, and it turned out to be the most basic. It only described some simple examples, and then went from the simple to the deeper.
It involves basic concepts such as the weight and volume of matter, then basic mechanical concepts, and finally the concept of electromagnetism.
Lin Yan was very satisfied. This was what she needed most. She feels that many things are already common sense, but she doesn’t know how to explain them.
Nowadays, if you are learning from scratch, you still need professional books as guidance to study systematically.
With the textbook available, Lin Yan fell asleep with satisfaction.
The next day, I followed my mother-in-law to see the situation in the fields and helped cut the grass and stack the haystacks.
At night, Lin Yan said to Hua Hong, "Mom, I want to use the room in the middle of my house to teach my friends."
"What are you studying?" Huahong was stunned. When they were still living in the cave, those children often asked their daughter to study. Why should they still study?
"It may take a longer time to learn some new things. They will come to our house often in the future. Auntie, do you agree?"
Learning is a long-term process. There are more children in the family. I don’t know what Hua Hong thinks, but we still need to communicate first.
"How long will it take to study?" Huahong asked. In fact, she felt more at ease having her children staying with Lin Yan. Although the home was safe, Lin Yan was still too young.
Lin Yan hesitated for a moment, "I'm not sure. It depends on how fast Yeya and the others learn. It may take a few years."
"Are you going to eat at our house?"
"No, let's go back to our homes during dinner."
"That's okay. You have to get along well with those children and don't get bullied."
Lin Yan smiled and nodded, "Aniang is so nice. They will be grateful to Aniang in the future."
Hua Hong didn't care about future gratitude. She only wanted to have her children with Lin Yan for now.
After dinner, Lin Yan went next door to Ye Ya and proposed that she would organize children's studies and asked Ye Ya if she would like to join.
Of course Ye Ya is willing, he is Lin Yan's follower, "Who are they?"
Lin Yan said: "For the time being, we have decided on Hong Ling, Shi Zhi, Shui Sheng, Hua Min, Lan Yue, Bai Chen, and you."
"Who are Hong Ling, Shi Zhi, and Hua Min?" Yeya looked confused. When did these unknown friends appear?
"Haha, it's just grass branches, small stones and flowers. They have new names."
Ye Ya immediately said: "I also want to choose a new name, well, I'll choose Ye Cong, I'm the smartest."
"Okay, okay, it's better to call her Ye Cong." Ye Zi just heard and agreed very much, "The same last name as mine. From now on, everyone in our family will be named Ye."
Mu Shi had no opinion on this. The tribe respected mothers, and it was normal for the children to have the same surname as their mothers.
Nowadays, every household is basically headed by a woman, and the children take their mother’s surname.
Ye Cong also smiled, "Auntie, please call me Ye Cong from now on. Don't call me wrong."
"Okay, my son's name is Ye Cong, and grandma will call you that from now on." Ye Zi looked at him and Lin Yan with a smile, "When there are more children in the future, you have to protect Lin Yan and don't let her be bullied."
Ye Cong puffed up his chest and promised, "I will protect Lin Yan. I will beat anyone who bullies her."
Seeing his serious look and small body, Lin Yan couldn't help but burst into laughter.
"Ye Cong, you are so cute."
Ye Cong frowned, "I'm serious. I'm older than you and can protect you."
"Yeah, I know you are serious, I won't laugh, okay?"
On September 1st, Lin Yan took a group of children and started a new study.
In the main room of Lin Yan's house, there is a large stone slab and homemade charcoal.
The children each came here with their own stools and slate charcoal pencils.
The children Lin Yan mentioned were all here, and there were some twists and turns in Shui Sheng Neng's journey. It was Mrs. Shui's firm support that made Shui Hua agree.
Other children's families are very supportive, and their parents want their children to become as smart as Lin Yan.
The simple classroom made Lin Yan extremely disgusted, but it was the best he could do.
She glanced at the children who were sitting obediently and declared seriously: "From today on, I will teach you three subjects, mathematics, physics and chemistry. Let me talk about the rules first. Once you come, you can't give up halfway. You need to persist every day. .”
"Each subject will have one class in the morning, and the same in the afternoon, and the rest will be adjusted according to the learning progress. If you encounter something you don't understand, you can ask questions at any time, and everyone will discuss it together."
The children were eager to try, their eyes wide open, wondering what they were going to learn today.
Shi Zhi was the first to ask: "Which course should I study first?"
"Mathematics." Lin Yan turned around and wrote the four symbols of addition, subtraction, multiplication and division on the slate, and then listed a few simple calculations.
"You have already learned the ten numbers from 0 to 9, and you also know addition and subtraction. Today, we are going to learn the four most commonly used symbols in mathematics..."
There were eight children in total, and they listened with great rapture. Entering the wonderful world of mathematics for the first time, they understood all the simple addition and subtraction algorithms and verbal and mental arithmetic before.
It's a completely different feeling when everything is clearly displayed with words and symbols.
The four basic symbols have been understood, and the basics of addition and subtraction have been established. The focus of Lin Yan's lesson is the algorithm of multiplication and division. She listed the multiplication table.
The eight children selected from more than 3,000 children learned really quickly and understood everything at once.
Lin Yan only spoke once and they were able to draw inferences.
