"Several information teachers, the Municipal Ministry of Education issued a notice for us to organize at least five students to participate in the city computer competition, we Jiangcheng No. 1 Middle School opened courses relatively late, I think we go to make up the number, but we have to use this opportunity to study, this time select a few students to participate, I see which way, you will carry out some targeted training, so that talented students can give them extra time to take more classes. ”

"Teacher Yang, Teacher Wu, Teacher Li, Teacher Zhou, Teacher Qian, you are all part-time information classes, you are young teachers, although you have been exposed to computers in college, but they are not computer majors, this time you will see the main, look at our Teacher Cheng's guidance, you follow the study, Teacher Cheng Yan will not be in our school for too long, she wants to take the postgraduate master's degree, you have to seize the opportunity. ”

The principal recruited Cheng Yan into No. 1 Middle School not only to lead classes, but also to bring these non-professional amateur teachers, and other teachers also knew about them.

So they nodded their heads.

"By the way, Mr. Cheng, you took the initiative to report to the school in advance that a student wants to participate in the computer competition, what is the level of that student?"

"I don't know what the other classes are like, but in the five classes I teach, he is definitely the best at computers. ”

Cheng Yan said that she didn't tell what she knew about him, after all, she is now the most professional in computer science in school, and no one believes it!

"Teacher Cheng has a very high evaluation, it seems that the student's family conditions are good, he should have been in contact with the computer very early, this time I will focus on guiding him, which makes our Jiangcheng No. 1 Middle School have better grades when the time comes, so please ask Teacher Cheng." ”

The principal does not hold that the students can win the glory and win the award, and the award must be won by the students in their city, and they have a microcomputer class in the nineties, no way, the conditions of the big city are not comparable to Jiangcheng,

Cheng Yan really wanted to say that the student would definitely surprise the school, but she didn't know what Zhou Xian's real situation was, and she needed this kind of competition certificate to know.

So, she didn't say anything more, after all, her personality is still cautious.

I said in advance, if Zhou Xian's classmates messed up, the principal and uncle would not be happy in vain, so it would be better to have an unexpected surprise at that time!

After receiving the principal's assignment, the teachers began to discuss how to let the students make up the numbers.

After all, No. 1 Middle School only started to conduct microcomputer classes this year, so forget about the exam or something, what did you not learn, what can you test?

So how do you choose the person who makes up the number?

A teacher suggested: "Then it depends on who has the fastest code words on the computer, to recommend the number, oh no, it is to determine the number of students participating in the competition." ”

"I agree with the method proposed by Mr. Qian. ”

"I'll just say that Teacher Xiao Chengyan is from a professional background, and she has a better way to make up the numbers, oh no, the way of selection. ”

"At present, the computer level of a middle school student can only be selected from typing to select candidates for the competition, we can do this, first select some of the better performers in each class, and then concentrate on their study for a week, and then select ...... from among them."

......

A new week.

The microcomputer class that the students are looking forward to has started again, a theoretical class and a practical class.

Students are not interested in listening to theoretical classes at all, what binary so-called information encoding is to use a small number of basic symbols and a certain combination of principles to distinguish and represent information.

In a computer, the basic elements of information encoding are two numbers, 0 and 1, called binary code, and the computer uses a combination of binary code 0 and 1 to represent all the information, which is called binary encoding.

"The teacher feels that this is another feeling of the world, why not use the decimal system, why not design it to be the same as our decimal system. ”

"000101010, who can understand what this thing is, only 0 and 1 are used. ”

"This classmate, the expression of the computer is not like our human brain, after all, it is a machine, and binary is easy to use two opposing physical states to represent the easiest to achieve, this is the use of binary encoding inside the computer, and the reliability is high, in the digital transmission and processing do not agree to make mistakes, easy to logical operation......"

"Oh, teacher, I feel that I understand, but I don't understand it very well, and our use of the computer has nothing to do with these theories. ”

For these computer basic pure theories, most students are not interested, their interest lies in surfing the Internet, in opening the computer can browse a lot of things, even if typing can also practice pinyin, the binary theory they learn the feeling of not being used on the computer, what decimal to binary, hexadecimal to binary, a few people are listening to it with relish, feel interesting, most of them are completely insensitive.

"What you see on the computer is built by these basic theories of 0 and 1, showing what we all understand, learning computers, students who are interested in computer science, these are very fun, because you learn that this is your tool, you can write code, make a small game, you can design a program, what to do......" Cheng Yan said more and more eyebrows danced, bringing the class into a computer background as if they could do whatever they wanted.

For enlightenment, Teacher Cheng passed very well, because she took many times more classes than other classes and chose computer science......

Computer-based lessons.

"Students, we type in this class?"

"The teacher is typing again!"

"Typing in this class, who can complete 300 words typing in three minutes, is the opportunity to pre-select our school to participate in the city computer competition, students take advantage of the opportunity!"

The typing speed of four students in the sixth class of high school reached the standard.

Zhou Xian, Xu Xiulin, Lu Xueqi, Lin Yinqiang, a veteran driver who specializes in secretly surfing the Internet.

The other classes were almost two or three people, and finally 50 people from Jiangcheng No. 1 Middle School were pre-selected, all of whom were students in the first and second years of high school, and the third year of high school students would take the college entrance examination immediately, and the school would not let them participate.

Teacher Cheng Yan's additional training is after dinner in the afternoon, that is, in the evening self-study tutoring class time.

At night?

Zhou Xian was not happy.

He's busy.

"Teacher, my training is not necessary, I don't go to evening self-study. ”

Those microcomputer classes during the day are mentally retarded enough, and they still come at night.

"Don't you listen?" said Teacher Cheng Yan.

"You tell me about that piece, I'll see it myself. ”

"The content is to finish all of our theory classes this semester and one week next semester. ”

"Would it be useful to pour it all at once?"

He didn't ask it for himself, but for the sake of the group of classmates who passed the typing test.

Digesting so many theories in such a short period of time, unless you are a genius.

"Temporarily, it should be better than nothing to say, and when the time comes, it will be up to you to select five in the written test. ”

"I don't need to be a teacher, and I don't need a written test selection, I go directly to the competition, you know my level. ”
