Process method
Teacher's explanation+student's practice+student's demonstration+teacher's evaluation.
Emotional attitude
Cultivate students from an early age to have the habit of saving files, and at the same time develop good information technology literacy, respect other people's labor achievements, and don't delete other people's files.
Second, the teaching points:
Teaching emphasis: 1, information storage form, memory and storage capacity. 2. File type.
Teaching difficulty: You can save the file in the specified location through learning.
Third, the teaching process:
(1) import
When students go to the library to borrow books, they see that books are stored in different shelves according to different categories, which are neatly arranged and easy to find. In a computer, information is stored in the form of files on disk or CD-ROM, and these files can also be stored in different folders.
(2) Newly awarded
(Writing on the blackboard: Lesson 8 Saving Files)
1. files and folders
Teacher: In general, files are kept in folders. In order to facilitate the management and use of files, each file has its own name, called file name.
(blackboard writing: file name)
Teacher: A file name can be expressed by letters, numbers, Chinese characters or symbols, and usually consists of a main name and an extension.
(blackboard writing: composed of the main name and extension of the file)
(demonstration)
(1) Open the folder containing the files "Clouds.bmp" and "frogs.wav".
(2) Teacher: files "Clouds.bmp" and "Frog". Wav "you see, where" cloud "and" frog "are file names. Bmp "and" Wav is a file extension, which stands for different file types, and bmp stands for picture file.
Teacher: In Windows98, different files or folders are represented by different icons.
[give it a try]
Can you tell what the file name is from "C: C C: C:WindowsMediaDing.wav"? What are the main file name and the extended file name? What is the file type?
Teacher: You can see that the file name is "Ding.wav", which belongs to the sound file.
2. Create a new folder
Teacher: Students see an icon like a file package in the computer, which means folder. Just like the bookshelves in the library, we can put files in folders.
(blackboard writing: creating a folder)
Teacher: Do our children want to have their own folders? Let's take you to set up your own folder.
(demonstration)
(1) Open my computer;
(2) open "d":
(3) choose Chinese input method;
(4) Click the "File (F)" menu and point to the "New (N)" and "Folder (F)" commands.
(5) In, enter "Xiao Ming's folder", click the blank space of the window or press enter.
(Blackboard: Open Drive D- Select Input Method-File (F) Menu-New (N)- Folder (F)- Enter Folder Name-Click)
[practice]
Use the following methods to create a folder with your own name.
(1) Open the browser.
(2) Create a new folder under disk D. ..
Step 3 remember
[question]
(1) We learned before, what is the name of the device used to save information in the computer?
Teacher: Memory.
(2) What kinds of memories are usually divided into?
Teacher: There are two kinds: internal memory and external memory.
(3) What are the commonly used external memories?
Teacher: There are floppy disks, hard disks and CDs in common use.
Teacher: No matter whether the storage capacity of floppy disk, hard disk or CD is large or small, we all use the number of bytes to express the capacity. Generally, when storing information, an English letter takes up one byte and a Chinese character takes up two bytes. Bytes are represented by Byte or b, and 1B represents a byte. In addition, kilobytes, megabytes and gigabytes are represented by KB, MB and GB respectively. The relationship between them is:1kb =1024b; 1MB = 1024KB； 1GB= 1024MB .
(blackboard writing: storage capacity: KBMBGB bytes)
Teacher: The capacity of our commonly used 3.5-inch floppy disk is 1.44MB, which can hold hundreds of thousands of Chinese characters. The capacity of computer memory is usually more than tens of megabytes; The capacity of computer hard disk is more than several hundred megabytes. At present, 10G~30G hard disk is used at home. The capacity of an ordinary CD is over 600 megabytes.
[discussion]
What are the commonly used external memories?
Teacher: floppy disks, hard disks, CDs, etc.
[reading]
Teacher: floppy drive is referred to as floppy drive; CD-ROM drive for short. When using the disk, the disk should be moisture-proof, anti-magnetizing, anti-bending and anti-high temperature; The hard disk should also be shockproof. Don't touch the floppy disk film and the read-write surface of the CD with your hands.

How to input text into the computer?
Today, in this class, we will learn "Lesson 7, Part II Input Text" (paste the theme).
What do you want to know about "typing words in the computer"?
Health: I want to know: how to input text?
What tool is used to input text?
What is the method of text input?
How many steps does it take to enter text?
Teacher: With these questions, let's continue our study.
(1) Intelligent ABC Input Method
You need a keyboard to enter text on the computer. The main keyboard area of the keyboard has 26 pinyin letters, which can be used to input text.
Some students may say, I have used them all, why can't I just input pinyin to write Chinese characters?
That's because, by default, the computer inputs English letters, and we need the help of a good friend, that is "Chinese input method". There are several Chinese input methods. In this lesson, let's learn the "intelligent ABC input method" (stick a note). Please read with the teacher: …
How to find the intelligent ABC input method?
We should first find the En or CH icon (paste the note) and then read it together: ...
Look for "En icon" in win98 operating system and "CH icon" in win2000 or winXP operating system.
Now please follow the teacher's instructions, find the En or CH icon in the lower right corner of the desktop and the taskbar, click, and then find the smart ABC input method from the pop-up input method, click. In this way, we chose the intelligent ABC input method, and the original En or CH icon became ABC.
After learning this, let's look at today's first lesson "I'm going to break through the customs" and take out your study materials: "Dear students, will you choose the following three stars? Come on! " Let's compare and see who can win these three stars.
Level 1: Open the WordPad, then start the "Intelligent ABC Input Method" and enter "I" and "clothes" in the WordPad.
If you want to get through the first level, you must teach yourself the first page of the textbook-P29-Step 1- Step 5. If you don't understand anything, you can ask your teacher or your classmates.
Who can stand up and say how you did it?
Is your method the same as his?
Have you encountered any difficulties? How did you solve this difficulty?
A) tablets just want to run.
B) Choose another input method.
C) Only capital letters can be entered.
D) I chose "doubles" in smart ABC.
The teacher corrected them one by one.
Level 2: Please enter the following Chinese characters in the WordPad.
I talk to the rain, please don't wave.
Did you encounter any difficulties? How did you solve it?
(2) Select Chinese character input
Then we enter the third level and use the "intelligent ABC input method" to input the word "weaving" in the tablet. To break through, we must first study the textbook P29.
Who stood up and told me how you did it?
There are two ways to turn pages to find Chinese characters:
1. Click the down arrow.
2. Press the+and-keys on the keyboard.
What method did you use?
There are two ways to choose Chinese characters:
1, press the number key before the corresponding word,
2. Click the word you want to choose directly with the mouse.
Enter the last level of today, the fourth level: the letter "V" on the keyboard means the pinyin letter "?" For example, to enter the word "green", just enter "Lu".
At the second, third and fourth levels, you can pick a star for each level. A * * *, how many stars did you get? Then turn to page 53 of the textbook and comment. How many stars did you choose and put a "tick" behind the corresponding stars?
(3) Simplify the code word input method
Please enter the word "year", and then count how many times you pressed the keyboard when you entered the word. "Six tricks", the teacher has a kind of magic. You can only press the keyboard three times to enter this word. Ask your classmates for guidance. 123. Did you enter the word "year"? God is not magical? Do you want to have this magic power to improve typing speed? In fact, this magic is not available in every word. Only 24 commonly used words are available, and other words are invalid.
Please read the textbook carefully and see if you can master this magic trick in a few minutes.
Let's go to the second section today, "Let your fingers dance".
When playing music, please follow the music and make your fingers jump on the keyboard according to the "beat" on the study materials.
(4) UFO is whispering
Finally, let's play a game. The teacher changed the game of "delivering packages". The teacher played a piece of music, which was equivalent to playing drums. The teacher has some word cards in his hand. I will show you one by one. After the music is over, whoever enters the most words will win. Let's compare and see who can win today's team champion and class champion. You get one point for every word you type.
Summarize what you have learned:
We asked some questions at the beginning of the class. Now, have you found the answers to these questions? Which question did you find the answer to?
Make a comment on the first question after class.
In the process of inputting characters, the teacher saw that many students did not pay attention to fingering. I hope everyone can play a better tomorrow with the correct fingering in the future.
Write down your learning experience of this lesson in the textbook after class.
