Junior high school information technology faces students with a brand-new look and new teaching guiding ideology. As an information technology course, teachers should cultivate and educate students with new teaching concepts and new teaching methods. Therefore, it is worthy of our serious study how teachers teach information courses well and how students learn information courses well.
In the seventh grade of junior high school, information technology course was taken as an elective course, and information technology teaching materials were compiled. In the new textbook, there are some internationally popular softwares: Windows98 operating system, Word for word processing, Excel for data processing, PowerPoint for slide production, PhotoShop for image processing, Internet for network roaming, FrontPage Express, and other information technology softwares. This book is quite rich in content. According to the teaching plan of the municipal teaching and research section, it is necessary to arrange information technology courses that conform to the teaching practice of our school. How to teach information technology in junior high school in the new semester? That's what I did.
First, thoroughly understand the teaching materials and fully grasp the characteristics of teaching and learning of each software. From teaching students "learning" to teaching students "learning", guide students to master the ability of autonomous learning.
Information technology courses focus on cultivating students' autonomous learning ability. Autonomous learning ability refers to the ability to choose and design goals, discover learning content, determine learning methods and ways, and manage learning process independently in learning knowledge and learning practice. This requires information technology teachers to change the previous teaching mode and grasp the teaching purpose of the new textbook. First of all, we thoroughly understand the new textbook. In the process of preparing lessons, more than ten softwares such as Word and Excel in the textbook are operated one by one, and the problems found in the course of use are recorded and the problems that students will encounter are predicted one by one, so as to guide students to ask questions in time in the course of listening to lectures and using computers. At the same time, give full play to students' abilities. According to the requirements of the textbook, only some main functions of each software are introduced, and the rest are left for students to use boldly. The homework arrangement is flexible, and some students do better than books or teachers require, which develops students' potential. From teaching students to learn to use all kinds of software to teaching students to learn, we will explore all kinds of functions contained in all kinds of software. Guide students' interest in learning and master the ability of autonomous learning. In this way, students' enthusiasm and interest in learning knowledge will be higher. Cultivating this learning method is of great benefit to students' self-study and quick mastery of newly developed software in the future.
Second, according to the configuration of computers in the school computer room, give a good information class. Make full use of existing equipment to improve students' overall level.
I think improving students' quality is not just something advanced computers can give. In other words, it is impossible to cultivate high-quality students without paying attention to the efforts of information teachers themselves and relying on advanced computer equipment. Therefore, in the course of information technology, we should try our best to teach all kinds of software according to our own reality, but it can't be perfect, so as to avoid one-sided emphasis on hardware factors and limit the teaching level of information technology courses in our school. According to the configuration of computers in the school computer room, give a good information class. Software that can speak and practice well. Point out the main points of software that students can't use on their computers and demonstrate them on teachers' computers. Through the joint efforts of teachers and students, we can overcome the problem of insufficient computer configuration in the computer room and greatly improve the level of all students.
Third, in view of the differences and specific problems of students in each class, strengthen teaching research in all aspects.
The goal of information technology education is to cultivate students' information literacy, basic information technology knowledge and information ability. In the teaching process, the differences in information knowledge and operational skills of all students are objective and inevitable. Then, as an information technology teacher, how can we do this course well and improve students' comprehensive quality?
We think this needs to strengthen the research in all aspects of teaching. From electronic lesson preparation, classroom explanation, computer training, individual counseling, homework, etc. For example, in preparing lessons according to the actual situation, we should not only let students learn the content well, grasp the key points and eliminate the difficulties, but also flexibly deal with the problems that often appear in computer classes, such as machine failure, software setting problems and improper operation of students. If it is not handled well, it may not be possible to complete the teaching requirements, let alone let some poor students achieve the teaching objectives.
In order to narrow the gap between top students and poor students in computer, students can be divided into three categories: good, medium and poor, and different requirements can be given to the three types of students in counseling. Especially in the process of students' computer operation, without high-end equipment such as computer LCD projector and classroom network software, it is impossible for information teachers to take care of all students alone. At this time, it is necessary to give full play to the advantages of those computer majors, assist teachers to complete the work of removing obstacles for students, and guide other students in specific operations. Make use of their advantages and let them drive the poor students, cooperate with each other and make progress together. Through the 45-minute class, let all students master information knowledge as much as possible. Only when you have a solid knowledge in class can you learn independently after class.
Fourth, sum up experience in teaching practice and gradually accumulate it, so as to continuously improve the teaching level of information technology courses.
With the advent of the information age, modern technology with computer and network technology as the core is developing continuously, which is changing our way of life, study and work more and more profoundly. At present, teachers of information technology courses in junior middle schools generally undertake many tasks in schools, such as teaching information technology courses in grade seven, cultivating students majoring in computer science, managing computer rooms and printing school materials. The task is heavy, and you will encounter many new problems and come into contact with many new ideas in teaching practice. At the beginning of the new semester, we should form a good habit of gradually accumulating problem-solving methods, new teaching ideas and exploring experience. If we can't cope with the past, we are finished. We can take notes or write papers and so on. By constantly summing up teaching experience and teaching practice throughout the school year, we can master comprehensive and rich teaching routines. We can constantly improve the teaching level of information technology courses and cultivate students' lasting interest in learning and their desire and ability for lifelong learning.
Information technology is the most active field of innovation, especially suitable for cultivating students' innovative consciousness and innovative thinking in a subtle way. Through the introductory teaching of information technology courses, students' ability to learn information technology courses is cultivated. Do a good job in classroom teaching, computer training and other teaching activities to improve students' information quality in an all-round way.
B. How to improve the efficiency of junior high school information technology classroom teaching
With the advent of the information society, the continuous development of modern technology with computer and network technology as the core is changing our production mode, lifestyle, working mode and learning mode more and more profoundly. The ability to acquire, analyze, process and apply information will be regarded as the most basic ability and quality of modern people. Cultivating students to master and apply modern information technology from an early age is the basic requirement for talents in the information society and also the requirement put forward by information technology courses. Computer education in middle schools is also developing vigorously. Accelerating the pace of educational reform, exploring effective teaching methods and using modern teaching methods to improve students' computer knowledge and practical ability, so as to improve the scientific and cultural quality, ability and scientific and technological awareness of future builders, are the fundamental tasks of information technology education in middle schools. How to tap students' learning motivation in the classroom teaching of this course and improve the efficiency of classroom teaching is a subject that our teachers should constantly explore. Through several years of teaching practice, I have gained some experience to share with you.
First of all, carefully arrange the lead-in to stimulate interest in learning.
Confucius, a great educator in ancient China, said, "Knowing is not as good as being kind, and being kind is not as good as being happy." Comenius also said: "Interest is one of the main ways to create a happy and bright teaching environment." Interest is the best teacher, the basis and premise of learning, and an important factor to induce students' learning motivation and concentration. Through careful introduction in the teaching process, students' interest in learning can be stimulated, thus achieving the purpose of improving efficiency. In my teaching practice, I mainly use the following import methods to import classroom teaching.
1, problem type
Learning with questions can make students' learning goals clear and targeted. Problem-based import can be divided into two forms. First of all, ask students questions directly, so that students can learn the content of the new lesson with questions, solve problems in the teacher's explanation and students' discussion, and achieve the goal of mastering knowledge from all sides. For example, when learning the section "Knowing Computers", first ask students questions in the lead-in: ① What skills does a computer have? What are the characteristics of computers? ③ How does the computer work? ④ Why do you want to learn computer? By asking these questions, let the students solve the problems one by one under the guidance of the teacher and through the contents introduced in the book, so as to master the content of this lesson well. The second form of question-based lead-in is to directly ask students what they need to learn in this class before the new content is given, which is straightforward and focused. For example, in the teaching of Document Operation, as soon as the class begins, we will come straight to the point and put forward what we need to master in this class. ① Copy or move files by dragging and dropping. ② Delete files by dragging and dropping. In this way, students can have clear goals, clear thinking and a clear aim. In short, the introduction of problem-based can make students have clear goals, grasp key points and stimulate interest. The effect is also better.
2. Demonstration style
Demonstration import is to import classroom content through the demonstration of courseware, which plays a role in stimulating students' interest. For example, in the process of teaching WORD greeting card making, I first demonstrated several beautiful computer greeting cards through the computer. When the students were admiring and admiring, I took the opportunity to say, "Students, are these greeting cards nice?" It's all made of words. Actually, it's easy. You can design a beautiful greeting card through today's study. "Students' enthusiasm and interest in learning have improved at once. In the teaching of FRONTPAGE web page making, I selected some excellent personal web pages made by previous students to show to students. When students see beautiful or vivid web pages, they are very envious and eager to make similar web pages themselves. Students' strong desire to learn can be realized in the process of generation, which fully embodies the learning attitude of "I want to learn", thus paving the way for later learning.
Step 3 compare
Compare the knowledge learned before with the knowledge to be learned, highlight the advantages of Protestant content and stimulate students' interest in learning. For example, in the teaching of "Creating and Editing EXCEL Charts", I put three forms of information together for students to compare. First of all, I show the information in the form of words, point out the shortcomings, and then convert it into the form of tables. Finally, I show the information in the form of a table. Through the comparison of three forms, students strongly feel the advantages of the chart form: vivid, clear and clear at a glance. This leads to the purpose and benefits of learning charts, and clarifies the purpose of learning. Therefore, good lead-in is half the success of classroom teaching.
Second, teachers boldly let go and cultivate students' innovative thinking.
Some teachers like to talk about everything in detail in their teaching. I don't think this is appropriate. There are four disadvantages: 1 It can not reflect the subjectivity of students' learning, and it is easy to form passive learning. 2. It limits the development of students' creative thinking, and their thinking is easily blocked. 3. The classroom atmosphere is not active, so it is difficult to stimulate students' interest in learning. It is difficult to teach students to learn independently.
In my opinion, students should have room for imagination in teaching, teachers should boldly let go, stimulate students' creative thinking, give full play to students' subjectivity, and achieve twice the result with half the effort. For example, in computer painting teaching, after analyzing the teaching materials, it is found that the methods of drawing circles, rectangles and rounded rectangles are the same. So I only explained the drawing method of circle in detail. Rectangle and rounded rectangle are only mentioned in classroom teaching, and the method is the same as drawing circle. Judging from the teaching effect, most students can master the drawing methods of the other two kinds of figures by drawing circles, so as to achieve the effect of analogy. For example, in the teaching of "surfing the Internet", it is difficult for students to master all the contents at once because of the large content of this class. Among them, it is difficult to search online through search engines. So, when I started teaching, I didn't put the content of online search into it. I filled in the website first, explained the browsing of the webpage, and then asked the students to practice. Ask the students to find out the problem in the exercise, that is, they want to find some information or visit a website, but they don't know which website and what the address is. After asking questions, let the students use their brains to solve them. It better be solved. If it can't be solved, let's discuss it together and finally summarize it by the teacher. Judging from the teaching effect, students have not only consolidated their knowledge, but also broken through the difficulties, which is really a multiplier. For another example, when explaining the content of web page decoration, you can first show a decorated web page, so that students can compare it with the web page made in the last lesson, and then put forward task 1: add background to the web page and modify the font, font size and color. Students can get operation information through "Help" and online learning websites. Because the students have learned word word processing software, task one can be easily completed, so they show a web page for comparison and put forward task two: add pictures, animations, music, horizontal lines and other contents to the web page. Teachers guide students to use the methods they have learned in word in the process of completing tasks, and realize the transfer of knowledge. Finally, the teacher summarized it. In the process of completing the whole task, all the students are full of curiosity and questions, actively participate in practice, give full play to their imagination and creativity, and dress up their own web pages with colorful and full personality. In the summary, the students spoke one after another, competing to tell their own conclusions and experiences, and the classroom atmosphere was very active. Facts have proved that students study and explore in this positive and relaxed atmosphere, and their brains are always in a state of excitement, and their knowledge and skills are very solid. At the same time, their subjective consciousness is brought into full play and their practical ability is constantly improved. Therefore, letting go boldly is conducive to giving full play to students' subjectivity, cultivating students' creative thinking and effectively improving classroom teaching efficiency.
Third, use scientific teaching methods to stimulate students' enthusiasm for learning.
In the process of information technology teaching, in order to keep students' learning motivation, we must use scientific teaching methods to stimulate students' learning enthusiasm. The teaching methods are generally "attracting teaching", "example operation" and "task-driven", and the principle of "focusing on use and cultivating ability" is adhered to, so that students can not only master the basic knowledge and skills of computers, but also experience the process of analyzing and solving problems and feel the joy of exploration, discovery, creation and success in the process of using computers to complete tasks independently. This is of great significance to cultivate students with strong practical ability and innovative ability. Among them, task-driven teaching method is particularly worth mentioning. The so-called task-driven teaching mode means that teachers design the teaching content to be completed into one or more specific tasks, so that students can master the teaching content by completing each specific task and achieve the teaching goal.
Task-driven teaching mode is adopted in teaching. Teachers' teaching and students' learning all revolve around how to complete a specific task. Teachers' teaching ideas are clear, students' learning objectives are clear, and students can master the learning content more easily. For example, there is a section in Word that introduces the use of picture boxes, text boxes, pictures and optional graphics. According to the task-driven teaching mode, instead of introducing the concepts, functions and operation methods of each part in isolation, all the contents are designed as the specific task of making a sub-picture, and the teacher explains how to make this picture, so that students can master the teaching content. The key points and difficulties in teaching are outstanding, and the teaching order is the process of making pictures, which conforms to the students' cognitive law. This makes the whole teaching process clear, distinct, logical and relaxed. Task-driven teaching mode also has advantages: improving students' awareness of active participation. In teaching, if the teacher always asks the students to listen, the students will easily get tired, and it is easy to develop the dependence psychology of waiting for the teacher to teach in class. If students are given a specific task in each class, they will have a sense of urgency to complete the task. In the process of operating, trying and creating, students will feel the success of their own exploration, thus fully stimulating their interest in learning and mobilizing their enthusiasm and active participation in learning. However, it should be noted that the task-driven teaching mode also has its own defects. The difference of students' learning ability will lead to polarization, which requires teachers to strengthen the communication between students and between teachers and students in the teaching process, so that students can improve together in cooperation. In addition, when designing teaching tasks, we should also pay attention to designing some interesting, practical and feasible tasks according to the characteristics of students, so that students are willing to learn, love learning and enjoy learning.
Fourth, cultivate information awareness and ability, and improve students' learning motivation.
Cultivating students' information ability and awareness is an important content to improve students' learning motivation. Information technology education should pay attention to the cultivation of students' information literacy, that is, the cultivation of information ability and information consciousness. The ability to acquire, analyze, process and apply information is the symbol of the most basic ability and quality of members of the information society. In the traditional teaching system, education is to a great extent-to let students remember all kinds of knowledge (information). This inefficient education has been difficult to adapt to the explosive growth of knowledge in the information society, and the demand for talent training is rapidly updated. We can say that in the information age, information itself is no longer important. What is important is how to establish a new basic skill system. In addition to absorbing the essence of traditional skills, we should also emphasize the cultivation of students' information ability such as information acquisition, information analysis and information processing, and cultivate creative talents with high innovation ability. Using computers as tools and using various teaching methods, we can develop students' intelligence and cultivate their practical and analytical abilities. Therefore, in the teaching process, the author tries to provide students with a "database" so that students can obtain useful information from the "database". Some students use all kinds of pictures and forms in the "database" to complete an illustrated and exquisite electronic greeting card for the teacher, and some students make curriculum, duty table, address book and so on to manage the class. Perhaps some students are not as good at learning with paper and pencil as other students, but their ability to analyze, process and apply information is higher than other students, which is exactly the demand for talents in the information society. In this way, students are educated in information literacy in the process of operation, students have their own ability and consciousness in the process of learning, and their motivation to learn computers is improved. I believe that as long as students have the motivation to learn, they will definitely improve their interest in learning this course. On the other hand, teachers can successfully achieve the teaching objectives in classroom teaching, thus improving the efficiency of classroom teaching.
Fifth, adopt various means to consolidate classroom knowledge in time.
1, talk less and practice more. Information technology course is an operation-oriented course. In teaching, the author found that the more the content, the more confused the students are. It is better to operate 10 minutes after a class. So I think in many courses that need to be operated, we should pay attention to talking less and practicing more. Through careful introduction, students can make clear the learning content of this course, and then teach new learning content and methods. Finally, consolidate the practice. Among them, the introductory and new teaching time should be reduced to about 15 minutes, and the remaining 18 minutes to 20 minutes for students to fully practice on the computer. Achieve the goal of consolidation, proficiency and improvement. 2. Teaching by stages. In teaching, we can also adopt the method of teaching and practicing in stages. The teacher teaches a piece of knowledge first, then lets the students practice, then teaches the next piece of knowledge after finishing, and then lets the students practice. In this way, students can absorb and digest the teaching content in time. Teachers can also grasp the students' learning dynamics in the first time and perform teaching tasks better. For example, in the basic operation of EXCEL worksheet, I first demonstrated several methods of inserting and copying data, and then put forward tasks, requiring students to complete several operation exercises according to what they have just learned. Let the students absorb and digest this knowledge at once. Then continue the following teaching tasks such as moving and deleting data. Through this method, students can accept new knowledge very smoothly, digest knowledge more easily, and the teaching effect of teachers can be ideal. 3. Use multimedia courseware to consolidate knowledge. This method is mainly aimed at some knowledge courses. The content of such courses is mainly the basic theoretical knowledge of some microcomputers, such as "understanding computers" and "understanding WIN98". A powerful theory. If the general method is adopted, the knowledge consolidation of these courses is monotonous. But it can be made into courseware, such as drawing and other forms of exercises, to achieve the purpose of consolidating knowledge. For example, in the teaching of "Understanding WIN98", I made a matching question of the names and functions of the desktop and various icons, which enabled students to match by moving objects, which was lively, consolidated their knowledge and cultivated their interest in learning.
Nowadays, science and technology in the world are advancing by leaps and bounds, and the speed of knowledge updating is gradually accelerating, especially the information technology represented by computer and network technology is changing with each passing day. In order to keep pace with the times, we must change the traditional learning mode of "teachers speak and students listen" and strive to train students to acquire knowledge and information actively through various ways and channels. Only in this way can we gradually master the ever-changing information technology and adapt to the needs of the rapid development of the information society, otherwise it will be eliminated by society. Classroom teaching is the main channel to learn each course well and the key to improve teaching quality. Students participate in teaching, constantly explore and study, choose different teaching modes and methods according to different teaching contents, apply them to each class appropriately, constantly sum up good modes and carefully design the teaching process. In short, only by constantly stimulating students' interest in learning, giving full play to students' subjectivity, cultivating students' creative thinking and creating a good learning atmosphere can classroom efficiency be effectively improved.
