teaching method
This lesson adopts teaching methods such as situational introduction, task-driven, demonstration, explanation and inspiration. Because most of the knowledge points of this course are based on specific operations, if teachers still adopt traditional classroom teaching methods, students will often feel monotonous and it is difficult to stimulate their enthusiasm for learning. Therefore, in view of the differences in age characteristics and understanding ability between junior and middle school students, teachers try to use situational teaching method to create virtual situations, explore fairy tale mouse castles, and put the key and difficult points of teaching into intense and interesting games to stimulate students' interest in learning. In the teaching process, according to the differences of students' different levels of mastery and ability, teachers use the characteristics of students' good performance to stimulate students to learn and communicate with each other, so that students can promote the development of innovative ability in an atmosphere of unity, cooperation and independent inquiry.
learning method
Group cooperative learning. According to the seating arrangement and students' computer application ability, two or three people in the vicinity are used as a study group, and the students with higher level are determined as the group leader. Under the guidance of teachers, students make clear their learning objectives and learning requirements, then make clear their respective division of labor through group discussion, conduct independent learning and exploration according to their own specialties, and make up for their own shortcomings through summary, thus improving their individual learning ability and knowledge application ability.
Instructional design intention
According to the teaching philosophy of Shanghai Information Technology Curriculum Standard for Primary and Secondary Schools (Trial Draft), the design of this lesson mainly considers the following aspects: First, consider individual differences and design tasks at different levels to meet the needs of students at different levels. On the one hand, it can improve students' interest in learning and let them experience the happiness of learning, on the other hand, it can publicize students' personality and cultivate their personal specialties. Second, in order to stimulate students' interest in learning, actively praise and encourage students at different levels.
teaching process
First, situational import, revealing the topic
1. Children, in this class, Dr. Q will introduce us to a new friend who is also a member of the computer family. We met him in several classes! Let's see who it is. (Courseware demonstration: Elf Mouse introduces itself 1)
Oh, it turns out that the new friend brought by Dr. Q is a mouse. Now the child can touch the mouse on your computer desk and make out with the child.
It seems that everyone likes this new friend very much and is eager to get to know him. What do you want to know? You can ask the elven mouse now. Who will ask this question? Guide the students to ask questions: How many parts does the mouse consist of? What is the operating posture of the mouse? What does the mouse do? Wait)
Children, in today's class, we will make friends with the mouse, know it, understand it and use it together. Let's look at the topic. (Exhibition theme: Use of mouse)
2. Task-driven autonomous learning
(A) learn to master the posture of the mouse
1. Now listen to the mouse's self-introduction. (Courseware shows the elf mouse introducing itself 2)
2. Do you have anything to add after listening to the introduction of Elf Mouse? (named answer: I found a wheel between the left and right buttons of the mouse)
You have observed it carefully. The teacher told us that this wheel is very useful when reading web pages and various documents.
In fact, the teacher has long known that many children in our class have computers at home, and some children may have made friends with the elven mouse at home. Who wants to be a little teacher and teach you how to master the mouse posture? (Name the students to be demonstrated on the stage)
You speak very well. Can the children understand you? Please pick up your mouse. If you can't, you can ask your classmates, or read carefully the paragraph holding the mouse on page 13 in the book, and open the book and turn to page 13. (Students teach themselves to hold the mouse)
6. Children, pick up the mouse together and let the teacher appreciate your posture. (The teacher corrects his posture while watching. )
Learn how to operate the mouse.
1. Transition: Son, your posture is correct. The teacher is so happy! Now please look up at the screen. Do you know, little friend? The mouse looks like a small arrow on the computer desktop, called the mouse pointer. Move the mouse and the small arrow will move with it. The mouse is the tool to control this small arrow. There are many ways to operate the mouse. The teacher asks the study group to discuss: What methods do you know to operate the mouse? Children can think about how to operate the mouse at home at ordinary times, or read the mouse operation method introduced on page 13- 15 in the book. (study group discussion)
2. Name the simple mouse operation methods: move, click, right click, double click and drag.
Children, the study and discussion just now only gave us a preliminary understanding of mice. Do you want to know more about mice? Now the elvish mouse has decided to invite us to play a treasure hunt in the elvish mouse castle. There is a lot of mouse knowledge in these games. Now let's go and have a look. Let's see if there is a file called "Mouse Task" on the desktop.
4. Who knows which mouse operation method to use to "open the file"? (roll call answer: "double-click" to open the file, that is, press the mouse twice in a row) (show blackboard writing: double-click)
5. You speak very well! Let's "double click" to open the "Mouse Search" file on the desktop. Children, have you seen the entrance to the castle? Let's go in. Let's read "Elf Mouse Tips" together. Courseware demonstration: children, you will meet a group of elven mouse guards at the gate of the castle. Only by defeating the Elf Mouse Guardian can we successfully enter the skill hall and learn the skills of mouse operation. Our first task is to "beat the mouse". (Write on the blackboard: Task 1: Click the mouse)
6. Please press the "Game Method" button. (The courseware shows the game method: 1. Move the mouse over the mouse head. 2.

Correct fingering is an important basic skill in computer operation. Good fingering can greatly improve the speed of computer operation and lay a good foundation for students' future study. However, it is not easy for primary school students to practice correct and fast keyboard fingering for the following reasons: 1. It is difficult to adapt to the alphabetical order of the keyboard. At present, the arrangement of letters on the computer keyboard we use is not a familiar order for primary school students. Many primary school students complain that the alphabetical order of the keyboard is too messy to remember, and some students even put forward the idea of inventing a new keyboard: all the letters are arranged in the order of "ABCD……".
2. Fingers are not flexible enough. Because most of the courses we usually learn don't use flexible finger movements, many primary school students' finger movements are clumsy: the little finger and ring finger can't move alone, the little finger moves, the ring finger moves, and the little finger moves involuntarily; Some students can't move their middle finger flexibly alone.
3. Fingering practice is boring. Compared with the active characteristics of primary school students, fingering practice is not very interesting. Many middle and lower grade students practice fingering for less than 5 minutes, which brings great obstacles to the completion of fingering practice tasks.
How to help students practice fingering happily and efficiently in primary school information technology class? In practice, I have adopted the following three effective methods:
Puzzle game, familiar with keyboard alphabetical arrangement
Learning activities involving multiple senses can effectively improve learning efficiency. Based on this, we designed a jigsaw puzzle that primary school students like to play to help them remember the arrangement of keyboard letters. We copy the keyboard diagram on hard paper, and then cut off the letter keys and numeric keys respectively. After confusion, ask the students to puzzle the keyboard as it is:
The first step is to hang the schematic diagram of the keyboard on the blackboard or put it where students can see it, and ask students to spell out the benchmark keys among the numeric keys and alphabetic keys. After proficiency, students are gradually required to spell out the upper and lower rows of letter keys and some commonly used punctuation keys.
Step 2, remove the keyboard from the blackboard and let the students spell out the number keys and letter keys step by step by memory. The whole keyboard puzzle can be broken down into several small tasks, such as spelling out the upper row keys, spelling out the lower row keys, spelling out the symbol keys and specifying a key. At the same time, some competitions can be held, and the winning students can be rewarded with small red flowers and five-pointed stars.
Students are eager to strengthen their perception of the keyboard in the game. The whole arrangement of keyboard letters leaves an impression on students' minds again and again, and with the later fingering practice, the arrangement mode of keyboard letters gradually enters students' subconscious.
Color classification, strengthen the sense of finger division of labor
At present, the letter keys and numeric keys of most keyboards are often uniform white, which brings a lot of inconvenience to beginners of keyboard fingering. When many students practice fingering, it is not easy to distinguish the division of labor of each finger, especially the keys such as R, V, C, I, M, ",". We use "keyboard color separation cover film" to help students clearly distinguish the division of labor between fingers. The "keyboard color separation covering film" is made of soft transparent plastic film, which is pressed into a fixed shape according to the concave and convex of the key cap, which can cover the keyboard keys more accurately and is not easy to deform. Different colors are printed on the positions of each group of keys struck by each finger to clearly distinguish the key positions. Such as "1", q, a, z and other key caps. The places hit by the little finger are all designed to be light cyan, and there are "2", W, S, X and other keycaps. The finger hit by the ring is designed to be light yellow, etc. And the color of the keycap of each finger is different. In this way, students will not be easily confused when practicing fingering, which greatly improves the efficiency of practice.
In addition, in order to help students practice their fingers more flexibly, we also designed some finger games for children, combining catchy children's songs to practice their finger flexibility. For example, in the game of "Big Brother bows to you, Second Brother nods to you, Third Brother bows to you, and Four Brothers and Five Brothers come to hit the cow", students are required to raise their fingers one by one and do the action of bending their fingers to hit the cow. Through these games, the flexibility of students' fingers has been greatly improved.
A variety of software, enrich the practice form.
Familiar with the arrangement of keyboard letters, knowing the division of labor of each finger, the flexibility of fingers has also been greatly improved, which has laid a solid foundation for practicing fingering. However, if you really use the correct fingering skillfully and reach the level of blind typing, it will take some time to practice. Because primary school students keep their attention on the same thing for a short time, if they use a single practice method, they will only feel bored. In practice, we integrate a variety of fingering practice software, and use children and games to train students' fingering from multiple angles. For example, the software "flying saucer" requires students to hit the flying saucer with the right button; The integration of spelling software and English subjects requires students to spell English words correctly according to the prompts; Jinshan Typewriter has more games to choose from-"Frog Jumping into the River", "Police Catch Thief" and so on. These softwares are generally from shallow to deep, step by step, to help students consolidate fingering step by step.
Learning any skill, just practicing without using it, can not only reflect the value of the skill, but also can not be further improved. When the students' fingering practice has reached a relatively skilled level, we began to let students learn to use the Microsoft Pinyin input method to practice inputting Chinese characters. At first, let the students only input the same sentence in a class, and practice the input of this sentence very skillfully to the extent of blind typing. After three or four hours of practice, I began to use online discussion software to start some online discussions, such as: cities you are familiar with, stories you like, and so on. Students have an online discussion with their partners with great interest. During the discussion, they not only increased their knowledge, but also greatly improved their fingering skills. In this process, according to the different levels of students, they can be awarded honorary titles such as "Little Typewriter", "Typewriter" and "Finger flick".
Through the above steps, the keyboard letter arrangement scheme gradually enters the students' subconscious, and the students' keystroke action gradually changes from visual control to kinesthetic control, and the typing speed is greatly improved. All these have laid a solid foundation for them to master information tools and fight the information ocean freely in the future.

Teaching background "How to set an appropriate email user name" is a knowledge point in the third volume of Anhui primary school information technology, lesson 1 1. The course "Apply for E-mail to gain something" should not only make students understand e-mail and apply for free e-mail, but also let them learn how to receive e-mail and send ordinary e-mail, knowing that the application of the Internet can bring great convenience to our lives, thus making students love information technology and network life more. Therefore, successfully applying for email plays a connecting role in this lesson, and how to set the appropriate email user name is a very key knowledge point, which is easy to confuse students, so this micro-lesson plays a very important role in the teaching materials.
Teaching objectives
1, master the setting method of common email user names.
2. Personalized email user name can be designed.
Emphasis and difficulty in teaching
1. Teaching focus
Master the setting method of common email user names.
2. Teaching difficulties
You can design a personalized email user name.
Teaching methods and learning methods
Create a combination of situational question introduction, dialogue and speech.
teaching process
First, create a scenario and introduce a question:
Student: He Laoshi, I have difficulty in applying for the email address of 126.
Teacher: What kind of difficulties did you encounter?
Student: I set the email user name according to the requirements of the website, but I can't succeed?
Teacher: Are there any tips on the website?
Student: I have reminded you many times that this email address has been registered. What should I do?
Teacher: This email address has been registered, which means that your registered user name has been used by others. Let's see how to solve this problem.
Second, answer questions, combined with the speech:
Teacher: Although the user name you set meets the requirements of the website, if it is repeated with others, the above prompt will appear on the page, which cannot be verified. How can we avoid repeating with others and successfully pass the website verification? User name combination is the key. Now I recommend several commonly used user name combination methods to you, try it.
Teacher: Li Ming, you must remember your birthday.
Health: Of course, my birthday is May 28th.
Teacher: Then spell your name and add your birthday number: liming0528.
Teacher's demonstration: give it a try, but it won't pass the test. Try to add the year combination, that is, liming20040528.
Teacher: This has been verified. This is the first combination I recommend to you, letters and numbers. User names using this combination are easier to verify and remember than those using only letters.
Teacher: short spelling of school name and short spelling of school name (courseware presented: dcdyxxlm Li Ming, Dangcheng No.1 Primary School). Of course, you can also use the short spelling of the class name and the short spelling of the name. (Courseware: yx4 1blm Class One Four (1) Li Ming) is a user name that is easy to remember by yourself and others.
Teacher: Li Ming, do you have a screen name?
Student: Of course, my screen name is Happy.
Teacher: If you don't like those combinations just now, you can use your screen name as your user name and the screen name "Happy Name" as your email user name. It can be the spelling of the happy name (courseware demonstration: kuaileming) or the happy name (courseware demonstration: happy_ming), which is not only easy to remember, but also full of personality.
Third, comb and summarize and encourage innovation:
Teacher: Li Ming, these methods combine personal information to form a memorable and distinctive user name, which can not only avoid duplication with others, but also pass the verification more smoothly and efficiently. Of course, there are many ways to set the email user name. I believe that when you apply for email again, you will definitely create more and more innovative user name combinations.
Student: He Laoshi, I know how to set my email user name now.
Teacher: Students in front of the computer, do you understand?
H: See you next time.
design principle
In the practical study of applying for e-mail, the improper combination of user names is one of the important reasons why students fail to apply for e-mail. By watching the video "How to set an appropriate email user name", students can master the common combination methods of email user names, and can combine personalized and innovative email user names that are easy for themselves and others to remember.
When designing the micro-lesson, considering that students watch the video independently by one-on-one, we first create a problem scene, where the protagonist in the video raises confusion, and then start tutoring through the dialogue between teachers and students, and integrate the familiar personal information into the email user name. Knowledge learning is gradual and easy to understand, which stimulates learners' * * * and is easy to accept. At the same time, it also increases the interest of micro-courses, and students can master new knowledge quickly and efficiently.
In the production of micro-courses, the combination of camera shooting and screen recording is adopted. The camera shoots situational dialogues, and the screen recording software records PPT explanations and operation demonstrations. Switch according to the plot and content in time, so that the audience can easily complete the learning task like watching TV programs.
The courseware adopts a mild green theme with simple and intuitive illustrations, which is lively and can also echo the theme of this lesson well.
