Liu Chen said unhurriedly: "I'm sorry, Jianghai University is written in the education column, it's not that I have graduated, but I'm about to enroll, in fact, I just graduated from high school, this is my admission letter." Pen & Fun & Pavilion www.biquge.info"

Xue Gang carefully checked the admission notice, and suddenly became interested: "You can be admitted to Jianghai University, it is said that it is a very good student, it is not easy, this holiday is the time to relax, how did you think of coming to us to teach summer classes?"

"The family is poor, find a part-time job to earn some money, and Jianghai University also has to pay tuition. Liu Chen said lightly, in fact, he is the champion of the province, where do you need to pay tuition, and give him a bonus of tens of thousands of yuan.

Xue Gang looked at his resume and frowned. I carefully read my resume and said: "You have a lot of things in your high school graduation meeting, I think many college students are not as good as you, it is no problem for you to teach the course of the first year of high school, but every teacher here is an experienced college graduate, even if you have the ability, parents can not rest assured that you can teach." ”

Liu Chen shook his head, pretending to be disappointed: "No, how did I hear that there are other students in the school teaching here, I thought you were eclectic and talented, but I didn't expect to value what forms of things." ”

Xue Gang stared at him, laughed and said: "Young man, it seems that you know a lot, you are talking about Zhuo Ling, right? She is not famous in our Suzhou City, and people do not get paid for classes, nor do they charge students for class fees, mainly to take everyone to appreciate some English movies, so as to improve their English scores, I don't know how many parents of students rush to sign up." ”

"Principal Xue, what if I don't want to be paid? ”

"I remember that you just said that your family is poor, and you come out to work part-time to earn tuition, but I'm not old and confused, why don't you want to be paid?"

"This ...... I want to be famous first, if you don't hire me, I won't make any money, and I can't make a name for free. The vision of life cannot be too limited. "A fool's errand.

Xue Gang looked at Liu Chen with blazing eyes, as if he wanted to see through something, and said, "I'm sorry......"

At this moment, a chubby young man rushed in in a hurry, holding a model-like thing in his hand. didn't knock on the door, and shouted directly in a loud voice: "Principal Xue, this thing doesn't work." ”

put the model directly on Xue Gang's desk, and then noticed Liu Chen on the side, slightly surprised.

"It took a lot of effort to make it. But the movement was too short to be captured with the best cameras. The visitor complained.

Xue Gang picked up the model.

Liu Chen also looked at what it was, a wooden cart with a pole on it, a small ball tied to it, and a separate cart, is this to simulate the motion process in physics? He was simply stunned, this method is too stupid.

Xue Gang is a physics teacher himself, and he knows that the last problem in high school is usually a complex involving sports, and most students are dizzy when they see it. I don't analyze the process at all, and if I can build several intuitive models visually, then the teaching effect must be much better.

Teacher Xiao Yue, who has been instructing the training center, to make a model, can you simulate several typical sports processes and shoot them, show them to the students, form an intuitive impression, and then analyze it to get twice the result with half the effort.

Xue Gang frowned and said, "Since the camera can't capture the movement process, can you start with the model and modify it?" For example, this spring is a little softer and longer. If the whole process is a little slower, there are more ways than difficulties. ”

Xiao Yue said with a bitter face: "Principal Xue, I really can't do it, I don't know how many brain cells have died all day long to do this thing, and people are almost stunned." You...... Another person, don't let me toss it alone. ”

"Teacher Xiao, for the sake of your classmates, make more efforts, this is a great merit, and then think of a way. I'll give you a big bonus when the time comes. "Xue Gang really wants to make such a set of visual sports models.

"Principal Xue, don't force me anymore, this ...... I'm really going to do my best, and if you do this again, I'll have to stop doing it. Xiao Yue is also iron-hearted, this bit of stuff drained his heart.

Xue Gang's face was disappointed and pity.

"Why don't I try it!"

Xue Gang, who originally looked at Liu Chen calmly and wanted to give him an interview opportunity, couldn't help but be stunned for a moment when he heard his words, "Teacher Xiao has been doing this thing for a long time, but it has not been successful, can you do it?"

The corners of Liu Chen's mouth raised, and he said: "Principal Xue, the most difficult motion problems in high school physics are basically spring, sphere, and trolley motion, as long as the thinking is accurate, it is easy to solve by using the principle of conservation of momentum, but many students are difficult to understand the specific process, you want to do a few typical motion model teaching, this method is very good." ”

Xue Gang pouted, this is not nonsense, I still want you to talk about it.

"As long as you understand the process of motion, the problem of physics is very simple. Liu Chen said.

"You have a solid foundation, the high school questions actually don't seem difficult, but the children's thinking ability is limited and it is difficult to figure out the process, and it is much more difficult to do the questions, but unfortunately, the teachers analyze the movement process too obscurely, and the students with poor thinking ability sound too difficult. Xue Gang sighed.

Xiao Yue stared at the mung bean and didn't speak, thinking to herself who this guy is!

Liu Chen said with a smile: "In fact, these motion processes do not have to make real models to simulate the motion process shooting, to be exact, this method is not advisable, after all, the motion process in physics problems is based on the ideal state, and it is difficult to achieve the effect in reality considering friction and other obstacles, let alone shoot the short process." ”

Xiao Yue patted her thigh and agreed: "That is to say, how can this be done." ”

Xue Gang glared, stared at Liu Chen and said, "I also know that it takes a lot of effort to do this, but do you have a better way?"

"It's very simple, simulating several typical motion processes, the students can see it at a glance, but the effect is much better than the teacher's effort. ”

"Simulation?" Xue Gang chewed on Liu Chen's words.

Xiao Yue, a rectum, was confused when he heard it, but as long as he could stop playing the role of a carpenter, he raised his hands in favor and said, "This method is good, this method is good." ”

Xue Gang glared, "Teacher Xiao understands simulation?"

He smiled awkwardly, "I ...... I don't understand, but it sounds reliable, that, boy, how do you simulate?"

Xue Gang pondered for a moment and said: "Liu Chen, how to simulate this dynamic process, it's not that we haven't considered other implementation methods, but they are all unsuccessful, what can you do?"

He couldn't help but show an expectant expression on his face, after all, looking at Liu Chen's resume just now was quite terrifying, and a lot of it was densely written, and he didn't understand many of the abbreviations. (To be continued.) )
