The interactive whiteboard is a comprehensive teaching medium that provides visual information such as images, text, graphics, symbols, etc., while transmitting auditory information such as speech, music, and other impressions. Modern educational technology teaching is flexible and diverse in form. It can be replayed, slow-released, fast-released, and still-pictured according to the needs of teaching. It can also carry out interactive learning activities between human and computer. Innovative teaching of mathematics requires mathematical experiments. In mathematics experiments, observation, analysis, comparison, induction, establishing relationships, processing data, and discovering rules, the application of interactive whiteboard technology provides a possibility for mathematical experiments. 1. The interactive whiteboard provides an ideal teaching environment for primary school mathematics. Through the sound and image of the interactive whiteboard, students can create a harmonious learning situation, so that students can enter the estrus, accept knowledge in a relaxed and pleasant atmosphere and beautiful feelings, and use external forms such as sound, light, color and image of the situation. To mobilize students' non-intellectual factors to participate in group activities and to arouse students' enthusiasm for learning. For example, when the second grade teaches students to ask questions based on real-life scenarios, I use interactive whiteboard technology to bring the ten-minute activity scenes between students to the classroom, and the students have a series of math problems. Returning to the classroom with questions, in this classroom environment, students are conscious, active, and natural. In the teaching, I have rationally designed and selected, and replaced the traditional chalk and blackboard with the means of interactive whiteboard technology. It has realized the teaching function of creating atmosphere, inspiring interest, various forms, efficient and fast. This is traditional. Teaching methods can't be compared. Second, the interactive whiteboard is conducive to organizing cooperative learning In a math class, cooperative learning is not applied to the entire teaching system alone, but is combined with the teacher's explanation, demonstration, refinement or generalization, and the independent study of the students. Cooperative learning is not an embellishment of classroom organization. existing. More can not be indiscriminate, "hands come", "competitive cooperation." In this way, it will only be in the form, and the students' learning efficiency and ability to solve problems independently will be greatly reduced. Therefore, group discussion and cooperative learning require us to organize and guide correctly. In teaching, teachers can combine the existing knowledge of students and use interactive electronic whiteboard technology teaching methods to guide students to think positively, discuss and draw conclusions. For example, in the teaching of "Peace and Jubilee", the advantages of interactive whiteboard technology are fully utilized. In the classroom, students are required to study in groups of three and propose cooperative learning requirements, that is, using the perpetual calendar in the computer to observe The number of days from February 1980 to February 2004 was recorded, and then the collected data was analyzed. Through the circle of activities, the regularity of the year and the leap year was discovered. At this time, the students interacted with the computer and cultivated the students' ability to be independent, cooperative, and inquiring, and let the students feel that "I am the master of the class." Of course, in interactive teaching, interactive whiteboard technology can also be used to propose cooperative learning requirements, so that students do not blindly cooperate or show the results of cooperative learning. When students draw conclusions through cooperative learning, groups of people express their own ideas, and often there is a phenomenon that others can't understand when the students express them. At that time, the teacher uses the physical projection or multimedia image to vividly put the students' ideas. Displayed, reducing the time for reporting after cooperative learning, is conducive to student learning. Third, the interactive electronic whiteboard has broadened the channels for primary school mathematics teaching When teaching some abstract mathematics knowledge, only letting students read the contents of the book, listening to the teacher's explanation and exerting their own imagination is far from meeting the teaching requirements. The emergence of interactive whiteboard technology provides students with emotional information. For example, when a teacher teaches "Integer Recognition", there are two questions (1) "How high is 100 million sheets of paper?" Provides some background pictures for students: Everest, the highest peak in the world, at an altitude of 8884.13 M, the central radio and television tower is 410.5 meters high. (2) “100 million students join hands in a row, how long will it be?†The students are provided with a map of China and some information: the distance from Beijing to Xinjiang is about 3,200 kilometers. The distance from Beijing to Hainan is about 2,400 kilometers. The distance from Beijing to Shanghai is about 1600 kilometers. Students draw conclusions from calculations and compare them with these background data to feel 100 million. Teachers use courseware to understand large numbers in real things, and give real numbers to large numbers. Students use this perceptual knowledge as a fulcrum, and they have more specific understanding and understanding of 100 million, and they rely on the understanding of entities. The combination of real pictures, real data, and students' existing life experiences is highly effective in cultivating students' sense of numbers. Fourth, the integration of interactive whiteboards and mathematics can improve teaching effectiveness and efficiency The function of the interactive whiteboard is used to present the teaching content in a multimedia form, vividly and vividly, with vivid images, animations, background music and sounds. And it can be controlled freely and can interact with teachers and students. For example, when I teach "Equivalent Substitution", because the equivalent substitution is a basic method in mathematics, it is to replace a quantity with the same amount, which is more abstract, difficult to understand, and not good. . Therefore, I use multimedia to visualize the process of “changing†in the form of animation. When the student learns the "same amount can be replaced" exercise by operating the tool: 1 pineapple = 5 apples, 1 apple = 2 oranges, 2 pineapples = oranges. After the students draw conclusions, how to derive them through multimedia presentations allows students to visually see the process of equal replacement, thus deepening the understanding of the equivalent substitution ideas. I didn't preach the whole teaching process, but used the intuitive animation, which is difficult to understand in language, with clear explanations, and effectively let students think and understand, which is conducive to students' understanding of concepts and improving teaching effects. In short, the application of modern educational technology changes the form of teaching, and also changes the teaching methods of teachers and the way students learn. We must learn to make full use of modern educational technology to effectively assist teaching, integrate all aspects of mathematics resources to meet the needs of students' learning and inquiry, and provide students with rich learning resources to further improve students' mathematics ability and promote students. development of. However, when using interactive whiteboard technology to assist teaching, it is necessary to use it in a timely, appropriate and appropriate manner. At the same time, it must also bring into play the respective advantages of interactive whiteboard technology and conventional teaching methods, promote each other, complement each other, and make interactive The electronic whiteboard technology serves the classroom teaching and effectively promotes the teaching to modern teaching methods.
