Multimedia teaching method sharing 1. The integration of information technology and mathematics is helpful to create situations, stimulate interest and improve learning efficiency.
Einstein said:? Interest is the best teacher. ? Stimulating students' interest in learning can stimulate their spirit of exploration and curiosity. And multimedia teaching can use computer technology to integrate text, graphics, animation, audio, video, projection and other multimedia technologies, integrating light, shape and color, intuitive and vivid, which can directly act on students' various senses, stimulate students' interest in learning, and make the content more substantial and attractive. Completely changed? Teacher, a piece of chalk, fill your mouth? Types of teaching methods. Vivid screen images and animations can deal with the problems that teachers' language and teaching AIDS are difficult to solve, so that students can better understand the essence of things. 1. Create family ties and stimulate students' interest in learning. Modern educational technology can provide students with vivid and colorful teaching resources, create colorful, synchronous audio-visual and dynamic teaching feelings for students, and improve their interest in learning according to their curiosity, with twice the result with half the effort. 2. Visualize abstract mathematical knowledge and activate students' thirst for knowledge. Using CAI courseware to demonstrate can not only change the picture in the textbook from static to dynamic, but also simulate some abstract and difficult problems into real processes through images, sounds and animations, attracting students' attention and stimulating their curiosity.
Second, the integration of information technology and mathematics is conducive to optimizing students' cognitive process and improving teaching efficiency.
Modern educational technology can visualize abstract knowledge points through form, sound, emotion and meaning, so that students can directly perceive and understand the teaching content, which is conducive to highlighting key points, resolving difficulties, optimizing students' cognitive process and cultivating students' learning ability. 1. Highlight key points and deepen students' understanding of knowledge. In the process of application problem teaching, using modern educational technology can, on the one hand, pass? Color change, flicker, translation? Highlight key points, stimulate students' attention and find the relationship between conditions and problems; On the other hand, with the help of courseware, we can sort out and refine the corresponding conditions and questions, create activity scenes according to the meaning of questions, draw line segments, turn abstraction into concreteness, help students examine questions, understand the meaning of questions and inspire thinking. 2. Solve difficulties and develop students' thinking. In teaching, we often encounter some knowledge points that teachers want to explain unclear and students find difficult to understand. If we use the animation effect of multimedia, we can concretize the abstract truth, highlight the key points, turn the difficult into the easy and achieve the best effect. For example, in the course of angle classification, the focus of teaching is to understand and master the definition of five angles (right angle, acute angle, obtuse angle, right angle and rounded corner), and the difficulty is to understand the scope of the five angles and the formation process of the angles, especially the teaching of rounded corners and right angles. Because a right angle is an angle with two sides in a straight line, and a fillet is an angle with two sides overlapping, these two angles don't look like angles, and the range of angles is abstract to the naked eye. In order to break through the difficulties, in teaching, Mr. Wu of our school demonstrated the formation process of five corners (especially the flat angle and rounded corner) on the computer by using the animation effect of computer multimedia, so that students could intuitively see that the two sides of the flat angle were drawn into a straight line; The whole process of overlapping two sides of fillet. Through comparative practice, the visualized, concrete and perceptual hierarchical information is gradually deepened into abstraction, conceptualization and rationalization, and resources are transformed into strength, thus achieving the goal of breaking through difficulties.
Thirdly, the integration of information technology and mathematics can make use of the interaction of the network, give full play to students' main role and improve teaching efficiency.
The interaction of modern educational media technology is beneficial to the goal orientation and cognitive function of primary school mathematics teaching. Modern educational technology combines the audio-visual integration function of multimedia with the interactive function of computer, resulting in a brand-new and colorful man-machine interaction mode, which makes students have a strong desire to learn, thus forming learning motivation, generating incentives and realizing the teaching-oriented function. And multimedia network-aided teaching breaks the rhythm and solves the problems that traditional teaching can't solve? Multilateral interaction, teaching students in accordance with their aptitude? The problem is to combine the whole teaching with individual counseling organically, so as to teach students in accordance with their aptitude and give full play to their individuality freely. Neither the gifted students can have enough to eat because they have to take care of the poor students to slow down, nor the poor students can have enough to eat because they have to take care of the gifted students to speed up or increase the difficulty. In a word, the organic integration of information technology and mathematics teaching is helpful to stimulate students' enthusiasm and initiative in learning and to cultivate students' innovative ability and information literacy. In teaching, teachers can use modern information technology to assist teaching, create rich situations, mobilize students' multiple senses to participate in the teaching process, and encourage students to learn independently, which will certainly play the best teaching effect.
Share multimedia teaching methods. Middle school teachers, especially young teachers, should be good at learning and be willing to learn computer multimedia technology.
As an auxiliary means of teaching, computer multimedia technology has played an important role in our teaching work. Using multimedia technology, we can show students the problems that we can't express clearly in words, which is helpful to break through the key and difficult points in teaching. Showing students colorful videos, animations, pictures and other materials in the teaching process can stimulate students' interest in learning; By setting some questions, we can cultivate students' awareness of participation in the teaching process and deepen their understanding and understanding of the problems; Choosing the right teaching media can increase our classroom capacity and save time.
Without computer multimedia technology, the traditional teaching mode relying solely on teaching tools such as chalk and blackboard can't keep up with the requirements of modern teaching. It is imperative for young teachers to master certain computer multimedia technology and improve the level of courseware making. The school provides good conditions for young teachers to learn computer multimedia technology. First, the school actively creates an atmosphere for learning computer multimedia technology, vigorously advocates the use of multimedia technology, and provides special courseware production guidance; Second, the school is going to equip every office with computers, which provides a material basis for young teachers to learn multimedia technology. As a new force in school teaching, young teachers have abundant energy and positive innovative spirit. From this perspective, young teachers should also become pioneers in learning and using computer multimedia technology.
Second, how do I learn computer multimedia technology and courseware making?
1, cultivate interest, step by step
When I first joined the work, I knew almost nothing about multimedia technology and courseware making. However, when I see some teachers introducing multimedia technology into classroom teaching, I feel that courseware making, as a technology, plays a very important role in teaching, and I must master this technology. People often say that "interest is the best teacher". After cultivating my interest, I began to learn the use of computers and courseware making. Through learning, I know a lot of things that I haven't touched before, such as photoshop, frontpage, and various courseware making software, such as powerpoint, authorware, 3dmax, flash and so on. Now I have learned the "courseware platform" under the special guidance of the teacher. In the process of learning, I found that our commonly used courseware making software has many similarities. If we learn one of them well, others will gradually master it by doing it themselves and trying more.
2. Be good at research and ask more questions.
The process of learning is the process of constantly encountering problems and constantly solving them. When I was studying and using various softwares to make courseware, I encountered many problems. When I encounter a problem, I will think first. Every software has many functions, and we may only learn some of them. There are many functions that we need to try, study and ponder. Of course, there are many problems that I can't solve by myself, so I humbly ask other teachers. I believe that as long as we are willing to try, be good at thinking and asking questions, there is no problem that cannot be solved. Teachers who work in the front line of teaching may feel this way during the teaching process. We think some students still have to ask simple things. We think simple things may be difficult for students, so we encourage students to ask more questions. The same is true of courseware making. The problems that we beginners find difficult to solve may seem simple to others, so it is necessary to ask more questions in the process of learning courseware making.
3. Do it yourself and be willing to try.
Philosophically speaking, practice is the power and source of cognition, and it is also the only criterion to test whether cognition is correct or not. Applying this viewpoint to courseware making is to make your own courseware. Maybe we are very creative in a certain aspect, but we can't achieve it without doing it ourselves. We can start from simple, from simple to complex, and make several complete courseware according to our actual level. Only in this way can our level be continuously improved.
Third, several problems that should be paid attention to in the process of courseware making
1, select the appropriate media.
At present, there are many courseware making softwares developed, each of which has its own advantages, but it may also be insufficient in some aspects. Before making courseware, we should comprehensively consider the characteristics of the course to be taught and the content to be processed, and then choose what platform to use according to the advantages of different software. "Courseware Platform" and flash are both powerful softwares, and their animation effect, interactivity and handling of pictures and sounds are beyond the reach of powerpoint and "Monterey Glory" including authorware. But powerpoint is also a good tool for making courseware, and we can use it selectively.
2. Concise and practical is an important principle of courseware making.
When making courseware, many teachers often make their own courseware "beautiful", adding a lot of small animations, gorgeous pictures and exciting sounds to the courseware. I think this will not only fail to achieve the expected results, but may dilute the theme. These things that are not directly related to the classroom will attract students' attention too much. After all, computer multimedia technology is an auxiliary means, which is used to assist our teaching. The key to a good courseware lies in its practicality. It should be said that as long as it helps to break through the key and difficult points, arouse students' deep thinking and deepen their understanding of the problem, it is a good courseware.
In addition, I think it is unnecessary and unrealistic to try to deal with every class through computer multimedia technology. It often takes a long time to make a good courseware. The application of computer multimedia technology is not a denial of traditional teaching, but a beneficial supplement to traditional teaching. The key to improve students' learning efficiency lies in the classroom, which should be fully recognized when making courseware.
3. When making courseware, students' participation should be considered.
Quality education requires cultivating students' innovative consciousness, participation ability, practical ability and the habit of thinking from multiple angles. Some articles say that the past teaching mode was "human irrigation", and the application of computer multimedia teaching became "machine irrigation". This wrong practice is actually a misunderstanding of computer multimedia-assisted teaching. Before making courseware, students should be considered to participate in the teaching process, and some contents can be appropriately added for students to operate by themselves, so that they can really participate in the teaching process, so that students can understand that the problem is "so it is" rather than "so it is" and cultivate their ability to think and explore problems; In the setting of some questions, students should not be told the answers directly, but should be given enough thinking space to cultivate the habit of thinking from multiple angles. Only in this way can we improve students' practical ability, stimulate students' interest and deepen their understanding of the problem, and achieve good results.
Share multimedia teaching methods and make effective use of multimedia-assisted teaching.
It can create vivid teaching situations, truly transmit and feedback information, make the conversion and transition of various information types natural, stable and rapid, optimize classroom teaching, effectively solve the key points and difficulties in teaching, and make students' learning effect better; It can effectively cultivate thinking ability and enhance emotional experience. The author's thoughts and feelings are expressed through words, so we should be good at guiding students to explore words, get feelings from words and create songs. In the "new glass", let students focus on the main problems? What are the characteristics and functions of the new glass? Explore and ask students to say yes? What sentences have you read? . In traditional reading teaching, teachers often copy the paragraphs on the blackboard in advance according to the students' presupposition and bring them to class. This teaching method is a waste of time and difficult to attract students. Because of this, children seldom focus on the classroom. Without children's cooperation, the teaching effect is often half the effort.
Using multimedia teaching, teachers put paragraphs on the big screen according to students' experience and sentiment, display them with different colors or pictures as the background, and even insert music.
There is no need for the teacher to emphasize more. The child has focused on the big screen, and the teacher can set up multimedia according to the inquiry activities that learners participate in. In the process of inquiry activities, with the change of students' inquiry ideas, switching the required scenes increases the time for students to think and communicate, which can make students change from passive learning to active exploration of knowledge and truly become the main body in the teaching process. So as to greatly improve the effectiveness of classroom teaching, let students have fun in learning and taste the joy of success. This kind of operation can make students read and explore purposefully and let them express their feelings. At the same time, it also provides great convenience for students to learn independently and vividly.
The role of multimedia in teaching.
1. Multimedia is an auxiliary guide for students to enter the classroom. As the saying goes:? Interest is the best teacher. ? In a class, whether students can maintain a strong interest in learning after entering the course teaching is the basis of a good class. In class, teachers not only give full play to the advantages of new textbooks, but also use multimedia courseware as a tool to lead students into the knowledge hall. Show words, images and models on the screen through courseware, create situations and give lectures. These images are intuitive, expressive and controllable, colorful and charming, which can easily attract students' attention and stimulate their interest in learning. Therefore, students are guided to observe and think purposefully and orderly, and combined with the guidance and explanation of teachers, students' attention and interest are mobilized, so that students have a positive learning attitude and learn with eagerness and pleasure, which greatly improves the efficiency of learning.
2. Multimedia is an assistant for teachers to impart knowledge. Classroom is the main position for students to learn, the place for students to systematically learn scientific and cultural knowledge, the main place for teachers and students to interact and acquire knowledge, and the core of school education and teaching. How to make students acquire more scientific knowledge, scientific methods and skills in the shortest time, classroom teaching is still the main position of school education and teaching, so courseware is an important content of multimedia teaching and the guarantee of excellent classroom teaching. Courseware embodies a large amount of information, strong intuition, fast pace and high density. It stimulates students' reactions in all aspects through graphics, characters, animation and sound effects, which provides an important guarantee for improving teaching efficiency. It can visualize abstract concepts and processes, activate teaching content, stimulate students' interest, receive good teaching results, and become students' assistants in learning knowledge. The use of multimedia courseware can effectively make up for the shortcomings of traditional teaching, turn abstract into concrete, fully display the contents that are difficult to understand or things that are difficult to observe, mobilize students' visual intuitive function, and create a good atmosphere for breaking through difficulties. The various stimuli and colorful visual forms of sound and animation in multimedia arouse students' perceptual interest and stimulate their learning motivation. For example, in science class, some teaching contents are difficult because most students have never seen them with their own eyes. In the past, teachers often used wall charts to teach. Nowadays, multimedia teaching can be played through video demonstration. How about one? Live broadcast? Every student can clearly see the whole process of the demonstration experiment. Let every student have experimental experience, strongly stimulate students' visual senses, fully mobilize students' enthusiasm and participation, stimulate students' interest in learning science, greatly improve classroom teaching efficiency and improve teaching effect.
Application of multimedia teaching.
In the process of using multimedia teaching, the experience is summarized as follows:
First, multimedia teaching has changed the single and inflexible expression of chalk and blackboard in traditional teaching. Through the use of graphics, audio, video and animation, we can stimulate students' senses in many ways, mobilize students' senses such as vision, hearing and movement to actively participate in thinking, stimulate students' interest in learning, reduce the difficulty of thinking, improve their understanding of knowledge, and make the dissemination of knowledge easy to understand and intuitive.
Secondly, multimedia teaching visually displays some teaching contents or unobservable phenomena that are difficult to express in traditional teaching methods, so that students can quickly and intuitively receive a large number of related materials through slides in class, which not only avoids vague explanations before, but also deepens students' memory of what they have learned and understanding of problems through visual and auditory stimulation, and improves students' learning enthusiasm.
Thirdly, the dissemination of classroom knowledge in traditional teaching mainly comes from teachers' dictation and writing on the blackboard, which limits the amount of information in the classroom, while multimedia teaching can greatly increase the classroom capacity and improve the classroom effect in a limited time.
Fourthly, the use of multimedia courseware can concentrate the wisdom and teaching experience of all teachers and better display their talents and imagination. Teachers have good methods and good designs for preparing lessons, which are sometimes impossible in traditional teaching. Now, with the use of multimedia, this can be done easily.
Using the results of multimedia teaching.
Multimedia teaching can create learning situations more fully in the classroom, save teaching time, fully display the construction process of knowledge, and realize the mutual transformation of teaching knowledge in abstraction, static and dynamic, process and result, finite and infinite. Multimedia teaching can effectively break through the key and difficult points of teaching, better meet students' demand for knowledge, improve teaching quality and improve teaching effect. In order to make better use of multimedia in teaching, our school has trained teachers on the use of multimedia many times, so that teachers not only learned some basic skills of using multimedia teaching, but also liked multimedia teaching. In the process of helping each other, some teachers have learned to download and make courseware, so that teachers can enjoy the sweetness of using multimedia teaching through resource sharing and achievement sharing. Through the use of multimedia teaching and research activities, the atmosphere of using multimedia teaching in our school has been created, and the enthusiasm and enthusiasm of teachers in using multimedia teaching have been stimulated.
