Kaichi assigned the students at the front of each row to help put the rolls away, and he stacked them together and said to the students below:

"Okay, that's all for today, I'll go back and correct your papers, and then arrange the next lessons. ”

The day's lessons were fooled like this, and Jiayi felt relieved, and the next lecture paper could fool another lesson, just past the initial adaptation period.

It's a bit disrespectful to the teacher, and Jiayi doesn't think that the teacher's in-class test is a lazy behavior, which is very useful for students to find out, and students themselves can know what they are lacking in.

But the reason why Jia Yi took the test this time was really to touch the fish, because the arrangement was too urgent, Orlando just said to Jia Yi yesterday that he would come to class today, and he didn't know what course to arrange for the first time, so it was better to test it and touch the bottom.

When he returned home, Jia began to correct the test papers, and more than 100 test papers, Jia Yi corrected them until late at night. Jiayi felt that he had miscalculated, he originally thought that he would not have to go to class for the exam, and it would be easier, but he didn't expect that grading homework would be more tiring, and he knew that he should pull March and them together, and it would be much faster for several people to change together.

And there are two other classes to take tomorrow, which is a headache to think about, and Jia Yi feels that he may not be able to be a good teacher, it takes too much energy and time.

He decided to put together a standard answer when the time came, and let March and them help change it when the time came, or find two good grades to help change it.

After correcting the test papers, Jia started to count all the test papers to see which part had the most wrong questions.

In Jiayi's opinion, the pre-class math course is not difficult, mainly some simple plane geometry, and there are things like equations.

After the statistics, Jia Yi thought that the system of equations for pure calculation would be more correct, which seemed simpler in Jia Yi, but I didn't expect everyone to have a better grasp of plane geometry.

Maybe it's because the figures drawn by everyone when they depict the magic circle are geometric figures, so everyone has a better grasp of plane geometry, and Jiayi didn't grasp it well when he came out of the question, and some places were inevitably a little overclass, but there were also many students who solved it.

However, for the system of equations, although they were learned earlier and more basic, there are not a few people who make mistakes.

In the next two days, Jia Yi struggled to change the test papers, lecture on the topic, and also had a basic understanding of the foundation of the students below, in terms of geometry, everyone has no shortcomings, but in algebra, there are still a lot of defects.

According to everyone's progress, Jiayi formulated a brief teaching plan, hoping to target the majority of people, as for the small number of backward and advanced, they can only rely on themselves.

[This feels a little irresponsible.] Jia Yi patted his teaching plan, and felt more and more that he was not a good teacher, but fortunately, the teacher he met when he was in school was quite reliable.

After explaining the test papers to everyone, Jiayi's course is finally on the right track, and after the class every day, Jiayi goes back to revise his lathe, hoping to be more perfect, but because of the pre-class math class, his time is occupied a lot.

But it wasn't without its benefits, as he taught his students, his own understanding of mathematics deepened, reviewing some of the basics. Mathematics, if you don't use it much, you won't be able to remember many things, but the mages have a good memory, and this aspect will be better.

......

Jia Yi walked into his classroom with his books and a large stack of parchment, and he had been teaching his students for 8 or 9 days, and everyone was a little more familiar.

Everyone is also a little familiar with Jiayi's style, except for the general class, which is to do questions.

Jia Yi handed down the parchment paper in his hand and said, "You are not doing your homework very seriously, and the mistakes are still relatively high, if you make a mistake or omission when calculating the spell model, what do you think will happen?"

He looked around the circle, and only a few students dared to look at him: "Mathematical things must not be false at all, right is right, wrong is wrong, mathematics is not philosophy, one plus one is two, not sophistry what can be equal to three equals zero, only mathematics is the truth, and the development of magic is inseparable from the development of mathematics." ”

In fact, the course in the preparatory class is called arithmetic, more simple calculations, not so deep, but Jiayi hopes that the students in his class can exercise a kind of mathematical thinking.

But how should this mathematical thinking be exercised? Jia Yi himself does not know.

After today's lesson, Jia Yi took a look at the time, and it just so happened that every teacher in the college had a grandfather clock, and after this, the teachers had a much more accurate grasp of the time. Jiayi also took the course for a period of time before he was able to guarantee that he would finish the course at the specified time.

"Okay, that's all for today's lesson, I'll give you a few more questions, and you can hand them in next time. ”

After that, he began to copy the title on the white "blackboard" again.

"Ah~~" sighed at the bottom.

Someone whispered, "Do the questions again, is this useful?"

When Jia Yi heard this, he paused slightly, he himself couldn't know whether it was useful or not, the mathematics of ordinary people in China is better than that of ordinary people in developed countries in Europe and the United States, but in terms of high-end academics, there are relatively few people who have made achievements, and it can even be said that they are backward, but relatively speaking, China's original foundation is weaker.

Therefore, Jiayi can't say for sure that a large number of questions must be useful or useless.

After all, he didn't do education in his previous life, so he really didn't have much research on this.

Therefore, although he has left questions, there are not too many, at most only two or three questions, but they are quite difficult, and there are certain requirements for carefulness and knowledge.

In fact, it should be, and it is not a sea tactic.

However, Jia Yi did not produce many questions, more likely because there was no good paper here, and the printing was too expensive, so the questions could only be copied by Jiayi, which greatly limited his motivation to write the questions.

In fact, for papermaking, Jia Yi has some understanding, he was born next to the hometown of rice paper in his last life, and he also visited the rice paper museum, so he has some understanding of the manufacturing process of rice paper.

Although it is impossible for him to make paper comparable to rice paper with this half-understanding, it should be no problem to make ordinary paper with a discount... Right?

It's a pity that he lacked this motivation before, and felt that the parchment was enough, so he never really put this matter on the agenda, and now that he is half a teacher, he feels that this thing seems to be able to really be done.

Whether it is color, writing fluency, portability, cutability, and taste, good white paper is much better than parchment. The only thing that is weaker than parchment is probably that the magic of the current paper is not good enough to be used as paper for scrolls.

But in fact, ordinary parchment paper cannot be used as paper for scrolls, and only "parchment" made of monster leather can be used.
