2. Students understand the process of computer processing information.

Teaching difficulties: the concept of computer hardware and software.

Teaching preparation: computer and related software.

The teaching process

I, questioning the introduction

We know that the computer is also called an information processing machine, because it is very strong ability to process information. So, students you know such a high-performance machine it is actually composed of what parts?

With today's study, you will be able to solve this problem.

Second, independent study, explore new knowledge

1, first please read the book P.4-P.7 the first half of the book, while reading and thinking:

① computer is composed of which two parts?

②What parts of the computer hardware are made up of?

③What types of computer software are there? What is the purpose of each of them?

The teacher goes around to check the students' self-learning.

2. Naming students to answer question ①, the teacher adds explanations and pays attention to corrections.

After the students answered, the follow-up question: who will say in their own words what computer hardware and software?

Teachers explain: hardware refers to visible, touchable parts, like the mouse, monitor, printer, etc.; software is used to direct the computer to work with the command language, it is invisible, can not be seen, but left the software, the computer can not work properly. If the computer only hardware, it is like a person with a body, but no knowledge and ideas, but also can not do things for people, to make it "live" up, but also let it master "knowledge", the formation of "thought "- this is the software.

4, named students to answer the question ②, you have a few kinds of points? How to divide?

From the outside, the computer consists of a mainframe, a monitor, a keyboard, a mouse and speakers.

Functionally, the hardware of a computer mainly consists of a central processor, memory, input devices, output devices, etc.

5. Named students to answer question ③.

After the students answer, the teacher introduces the characteristics of the commonly used operating systems: DOS, Windows series, Linux, etc.; introduces to the students some commonly used application software and their roles.

6, 学们现在我们最常用的软件大多是外国人开发的，像操作系统Windows、办公软件Office、图形处理软件PhotoShop等等，他们把这些软件的价格卖得很高，但由于中国人还没有开发出同等优秀的软件，还是只能高价买进。 But the ambitious Chinese have not been willing to lag behind, but also developed some excellent domestic software, such as WPS, KV3000, Super Solver, etc., but the number is still very small, there are still a lot of excellent software waiting for students to learn to develop.

Three, students imitate the hardware as "self-introduction"

Through the study we have just known that the computer hardware is composed of the central processor, memory, input devices, output devices, and other four parts of the composition of the coordination of their work, each showing their skills. What exactly are their powers, and who do you think is the most important?

Please read again "a computer hardware" part of the content. Then students, you are the central processing unit, memory, input devices, output devices, one of the four parts, so that the students are divided into four groups, you have to explain to the other students their role and the importance of letting the other students feel that the computer without you really can not. As for the assignment of roles, wait for the students to read the book and choose their own.

Students first read the whole paragraph, and then choose one of them to read carefully, to fully prepare for your speech to convince the other students, you can also pull your fellow students to help you convince them.

Four, learn the process of computer information processing

Read the content of the text, who is going to say in their own words the process of computer information processing?

Summary of the whole lesson

Class, what have we explored together today? Tell your tablemates what you learned.

Teacher (explain): When the game begins, there is a stack of cards held in the dealing area. There are seven stacks of cards in the staging area, with one turned card on top of each stack. There are four target spaces in the window target area. The game consists of placing all the cards in the four target spaces in order from smallest to largest, starting with the ace, and differentiating by suit.

In order to do this, we need to move cards and turn them over. Cards can be moved to stack on top of each other in the staging area, or they can be moved directly to the target spaces. Moving to the stack in the staging area requires that the cards be placed underneath each other in order, red and black, from largest to smallest. Only stacks starting with a king can be moved directly to an empty space in the staging area.

When all the cards have been moved to the four target positions in accordance with the difference in suit and in order of size, you can see the successful performance of shifting cards.
