Instructional design idea and knowledge background of computer lesson plan 1
"Understanding the information world" is the first lesson in junior high school information technology class, including the concept, characteristics and functions of information. How to make students master the essential characteristics of information is the key to master concepts. Because I often hear the word "information", such as information society, information age, information explosion and so on. But what is information, students can't say clearly, and the concept of information is abstract, which is difficult for junior one students. How to make students master the essential characteristics of information is the key to master concepts. Students must understand it from a perceptual point of view, and then transition from information to information technology, so that students can understand the importance of information technology in modern society, thus enhancing their determination to learn information technology well.
Knowledge target
1. Understand the concept of information and what information is.
2. Understand several typical characteristics of information and its performance.
3. Know the role of information in human society and how to use information to serve mankind.
capability goal
Learn to use the information around you and master the main applications of information technology.
Emotional attitudes and values
1. Can realize the importance of information to human beings.
2. Be able to distinguish the authenticity of information and consciously resist bad information.
3. Stimulate the interest in information technology, and develop the attitude and habit of actively learning information technology.
Basic concepts of teaching key information.
The concept and characteristics of difficult information in teaching.
teaching process
First, the concept of derivative information
Question import:
Teacher: "Today is our first class. Do you know the name of our class? "
Health: information technology.
Teacher: Why did it used to be called a computer course, but now it is changed to an information technology course? What is information and what is information technology? (The teacher has questions)
Think about it. It is difficult to answer with the current knowledge level of students.
2. Play courseware: multimedia pictures and videos (transmission of ancient bonfire information, newspaper news excerpts, TV advertisements, trademarks of some commodities, etc. )
Teacher: What information can we get from pictures and videos?
A: Ancient war stories, Olympic reports, advertisements for Wahaha, Mengniu, Yili and other products.
To sum up the concept of "information": what we just feel from pictures, images and words is the information we get from these media. In fact, we are exposed to information all the time in real life. For human beings, everything that the five senses can directly feel, such as the books you read, the music you hear, the things you see, the smells you smell, the problems you think and the things you have done, are all information. Broadly speaking, all existence is information. In addition to what can be directly felt by human five senses, everything we perceive through various means and instruments is also information. Who can sum up what information in one sentence?
Health: Summary.
Teacher: (supplementary) information is an objective description of the state, characteristics and movement changes of things, as well as the interaction and connection between things.
Teacher: What information have you got in your life? Teachers can guide students to answer from TV, newspapers, radio, internet, family, school and society. )
Student A: Learn daily necessities, cars, transportation, comics, TV drama previews and so on.
Second, guide students to understand the characteristics of information
Teacher: We will find that information has some common features. Now let's take a look. What are the characteristics of information? What is information?
Play courseware: Feature 1: When we transmit information, some are transmitted through paper, some are engraved on CD, and some rely on the brain to remember and store information. When we need information, we get information from these carriers that store information. No matter how we transmit information, information is always attached to some medium. What does this show about the characteristics of information?
Teaching objectives of computer lesson plan 2;
1, understand computer viruses.
2, understand the characteristics and harm of computer viruses.
3, master the basic methods of preventing and controlling computer viruses.
Key points and difficulties:
Goals 2 and 3
Teaching aid preparation:
Related information, computers, projectors, slides, etc.
Teaching time:
2 class hours.
Teaching process:
First of all, computer viruses
Computer virus is a program, an executable code, which destroys the normal use of the computer, makes the computer unable to use normally, and even damages the entire operating system or computer hard disk. Just like biological viruses, computer viruses have unique replication capabilities. Computer viruses spread quickly and are usually difficult to eradicate. They can attach themselves to various types of files. When files are copied or transferred from one user to another, they will spread with the files. This program does not exist independently. It is hidden in other executable programs, which is destructive, contagious and latent. Light will affect the running speed of the machine, making it unable to run normally; What's more, the machine will be paralyzed, which will bring immeasurable losses to users. This destructive program is often called a computer virus.
Second, the performance and harm of computer viruses
After a computer is infected by a virus, it will show different symptoms. The following are some common phenomena for users' reference.
(1) The machine cannot be started normally.
After power-on, the machine can't be started at all, or it can be started, but it takes longer than the original starting time. Sometimes there will be a sudden black screen.
(2) the running speed is reduced
If it is found that when running the program, the time for reading data is longer than before, and the time for saving or adjusting files is increased, it may be caused by a virus.
(3) Disk space is rapidly decreasing.
Because the virus program needs memory resident and can be copied, the memory space becomes smaller or even "0", and any information of the user can't get in.
(4) The content and length of the document have changed.
After the file is stored on disk, its length and content will not change, but due to the interference of virus, the length of the file may change and the content of the file may appear garbled. Sometimes the contents of a file can't be displayed or disappear after it is displayed.
(5) Frequent "crash" phenomenon.
Normal operation will not cause a crash, even for beginners, command input will not crash. If the machine often crashes, it may be because the system is infected by a virus.
(6) Abnormal operation of external equipment
Because the external equipment is controlled by the system, if there is a virus in the machine, some abnormal situations may occur in the work of the external equipment, and some inexplicable phenomena may occur theoretically or empirically.
(7) Blue screen
There is often a blue screen, especially when you press the keyboard, it will crash as soon as you press it.
The above is just a list of some common virus manifestations, and other special phenomena will definitely be encountered, and users need to judge for themselves.
Third, check and remove computer viruses
The teacher demonstrated the computer antivirus software Rising Network to remove computer viruses.
Fourth, prevent computer viruses.
First of all, pay attention to it ideologically, strengthen management and prevent the invasion of viruses. Anyone who copies the information on foreign floppy disks to a machine must first check whether there is a virus on the floppy disk. If there is a virus, it must be removed, so as to ensure that the computer will not be infected by new viruses. In addition, because viruses are latent, there may be some old viruses hidden in the machine, which will attack once the time is ripe. Therefore, it is necessary to check the disk frequently and kill the virus in time when it is found. Ideological attention is the foundation, and effective drug testing and disinfection methods are the technical guarantee. At present, there are usually two ways to check and eliminate viruses. One is to add an antivirus card to the computer, and the other is to use antivirus software, which is basically the same. Generally, there are many users who use anti-virus software. Remember to note that preventing and eliminating viruses is a long-term task, not once and for all, and we must persevere.
Computer lesson 1 teaching plan 3
Teaching time: 9. 12
Teaching content: P5-7
Academic goal
1, students know the names and functions of computer parts.
2. Students know what computer software is and its functions.
3. Students understand the process of computer processing information.
4. Educate students in patriotism by introducing domestic software.
Teaching emphasis: 1. Students understand the functions of various parts of the computer.
2. Students understand the process of computer processing information.
Teaching difficulty: the concept of computer hardware and software.
Teaching preparation: computer and related software.
teaching process
First, question the import.
We know that a computer is also called an information processor because it has a strong ability to process information. So, students, do you know what parts such a high-performance machine is made of?
Everyone will be able to solve this problem through today's study.
Second, self-study and explore new knowledge.
1, please read the first half of P.5-P.6 by yourself and think while reading:
What are the two parts of the computer?
(2) What are the components of computer hardware?
③ What kinds of computer software are there? What are their uses?
Teachers patrol to check students' self-study.
2. Call the students to answer question ①, and the teacher will supplement the explanation and pay attention to the correction.
After the students answer, ask: Who will talk about the hardware and software of the computer in their own words?
Teacher's explanation: hardware refers to the visible and tangible parts, such as mouse, monitor, printer and so on. Software is a command language used to guide computer work. It is invisible and intangible, but without software, the computer can't work normally. If a computer only has hardware, it is like a person who has a body, but has no knowledge and thoughts, and can't do things for people. To make it "alive", we must master "knowledge" and form "thought"-this is software.
4. Say the students' names to answer the question. What's your score? How to divide it?
From the appearance, a computer is composed of a host, a monitor, a keyboard, a mouse and a speaker.
Functionally, computer hardware mainly includes CPU, memory, input devices, output devices and so on.
5. Say the students' names to answer question ③.
After the students answer, the teacher briefly introduces the characteristics of commonly used operating systems: DOS, Windows series, Linux and so on. Introduce some commonly used application software and its functions to students.
6. Scholars At present, most of our most commonly used software is developed by foreigners, such as operating system Windows, office software, graphic processing software PhotoShop and so on. They sell these softwares at a high price, but because China people have not developed the same excellent softwares, they have to buy them at a high price. However, ambitious China people are not far behind, and they have also developed some excellent domestic software, such as WPS, KV3000, Super Jieba and so on. However, the quantity is still small, and there are many excellent softwares waiting for students to learn knowledge and develop.
Third, students imitate hardware to introduce themselves.
Through the study just now, we already know that the hardware of a computer is composed of four parts: central processing unit, memory, input device and output device, which work in coordination with each other and show their magic power. What magical power do they have? Who do you think is the most important? Please read "1". Computer hardware again. Then, students, you are one of the four parts: CPU, memory, input device and output device. In this way, students are divided into four groups. You should explain your role and importance to other students so that they can't live without your computer. As for the role assignment, students can choose by themselves after reading it.
Students read the whole paragraph first, and then choose one paragraph to read carefully. Make full preparations for your speech to convince other students. You can also help you convince them with your partner.
Fourth, learn the process of computer information processing.
After reading the text, who will talk about the process of computer processing information in his own words?
Class summary
Students, what problems did we discuss together today? Tell your deskmate what you have gained.
Second lesson

Academic goal
Learn to switch.
Teaching difficulties:
1, to know the sequence of computer peripherals.
2. Learn to switch correctly.
Teaching preparation: computer, network
Teaching process:
First, the introduction of teaching
Second, the new curriculum teaching
Teacher's demonstration
Before waking up the computer, the teacher tested the children with the simplest questions. What do children do first when they wake up in the morning? The teacher repeats it again, which is the first thing.
Just now, the children said a lot, some said to get dressed, some said to wash your face, and some said to fold the quilt, but the teacher disagreed with the children. Think again, what should we do first thing when we wake up in the morning?
By the way, first, open your eyes. We children can only wear clothes, wash our faces, brush our teeth and so on. The same is true for computers. You have to open your eyes to study with your children. therefore
Step one, let the computer open its eyes. How come?
1, the teacher demonstrated the monitor to remind the power indicator to change color.
How can I open my eyes? Our goal is to let him play games with the children. We want him to move. What should I do in the second step? In fact, it is very simple, that is, turn on the power.
2. The teacher shows the "power" sign of the power switch, and at the same time checks the boot status of each computer.
After pressing, let the children say what you found.
The three lights on the left will flash at the same time, the first light will turn green and the other two lights will go out.
Now computers will study with children. Like painting.
3. The teacher shows some computer works first, and then demonstrates them to the students with "Golden Mountain Painting King Pen".
Just now, we asked the computer to draw some pictures for our children. It said he was tired. Let him rest. Let's learn how to turn off the phone first.
4. The teacher demonstrated step by step and taught the students to turn off the mobile phone and repeated it several times.
The first thing children do when they get up in the morning is to open their eyes. Then we will close them after going to bed. Then start to rest. The same is true of computers. Finally, let the computer close its eyes, or it will get angry if it doesn't rest well. Remind your child again that you must not let the computer sleep with your eyes open. Remember to turn off the computer monitor.
5. The teacher demonstrated turning off the monitor.
(b) Students practice turning computers on and off.
Under the teacher's organization, turn on and off the computer step by step.
Teachers' patrol guidance.
