First, the advantages of combining multimedia with tutorial system in teaching
1, use multimedia to create teaching situations, stimulate interest in learning, and inject vitality into the application of counseling programs.
Using visual multimedia technology can create vivid and interesting teaching situations, touch students' heartstrings with its unique shape, sound and scenery, turn static into sound and static into action, so that students can enter a lively learning atmosphere, thus arousing students' great interest in learning, and at the same time helping students to understand, making abstract knowledge and content more visual and easy for students to accept and digest. What impressed me the most was that when I was teaching rational number addition and subtraction in grade one, I took math class 4 first, but I felt that it was not ideal after I took it. In another class, I made a courseware temporarily, using a rabbit to walk on the number axis, integrating the addition and subtraction operations into the rabbit's movement, showing the operations intuitively and vividly, and making it easy for students to learn. After-class feedback is very effective, and students master arithmetic and rules well. This is because the pictures and scenes used at that time strongly stimulated the excited cortex of students' brains, especially in the addition and subtraction of mathematical numbers, which made students feel relaxed and novel, stimulated their strong interest in learning and exploration, and thus aroused their curiosity about knowledge.
2. The application of multimedia teaching can increase the teaching capacity, thus reducing the teaching plan and improving the teaching efficiency.
Multimedia teaching can quickly present curriculum resources to students, which can not only save a lot of time for teachers and students to lecture and write on the blackboard, but also enable teachers and students to impart more knowledge, increase the capacity of the classroom to a certain extent, save the space for tutorials, and achieve better teaching results. Later, when Mr. Xu Baoliang talked about my class, he was worried that the class would not be finished. Today, in the judgment process of AAS congruent triangles, I projected the pre-designed courseware onto the screen in time (teachers must know when to guide students to look at the big screen), so that students can gain more comprehensive and intuitive knowledge directly from the screen, which increases the classroom teaching capacity, improves the teaching efficiency, and can also prevent students from roaming in the classroom, which is convenient for teaching. Especially for the standardization of problem-solving process in junior high school mathematics teaching, it is also a complete and standardized teaching for students. Let the problem-solving process follow the pre-designed animation, especially when dealing with the teaching of Example 6 in this section. I present the problem-solving process in two steps on the big screen, and directly analyze the examples in class, which not only saves time, but also intuitively facilitates students to master the problem-solving ideas and teaching methods. Inspired by the headmaster, this paper presents the problem-solving process of examples on the big screen, which is convenient for the teaching of example-solving process, allowing students to clarify the problem-solving ideas and standardize the problem-solving process. More importantly, the problem-solving steps in the courseware just reflect the analysis of problem-solving ideas.
3. The application of multimedia teaching can make the teaching highlight the key points, dilute the difficulties and improve the implementation effect of the counseling plan.
Whether a class is good or bad, whether it is successful or not, is a very important aspect to see whether it highlights the teaching focus and breaks through the teaching difficulties, while traditional teaching methods in many disciplines are difficult to achieve their goals. For example, in the section of AAS Triangle congruence, the textbook requires not only to consolidate the understanding of the three judgment theorems I have learned before, but also to complete the reasoning, demonstration and application of the new theorems. Especially in the understanding of the first three judgment theorems, if teachers and students just talk blindly, it is difficult for students to understand the corresponding relationship between angles and sides. It is very simple to make the three judgment theorems into translation animation, and each judgment condition is better presented on the screen. With the movement of graphics, students can easily understand and remember the corresponding congruence conditions. Only in this way can we simplify the complex, turn the difficult into the easy, turn the abstract into the image, and make it easier to highlight the key points and difficulties.
4. Combine multimedia with tutoring plan to improve students' imagination and cultivate students' thinking ability.
Multimedia courseware can not only help students to understand and remember knowledge, but also help students to establish image thinking, develop spatial thinking and improve their ability to solve problems. Effective combination can teach students to cultivate their thinking ability through analysis, synthesis, generalization, judgment and reasoning. What impressed me the most was that when students were studying the teaching of lateral area's solution of a cylinder, I designed an animated picture of the cylinder's side unfolding, so that students could find that the cylinder's side unfolding became a rectangle during the animation.
The timely application of multimedia in teaching plan can help students form a correct and comprehensive view. For example, by using multimedia animation simulation and process demonstration, the static diagram can be changed into a dynamic diagram, from which the whole changing process can be observed, and students can observe, think and discuss at the same time, thus cultivating students' observation ability, imagination ability, comprehensive analysis ability and problem-solving ability, forming a correct conceptual view and promoting the development of thinking in depth. For example, in junior high school mathematics, the contents about symmetry, rotation and translation of objects are all designed with tutorial plans. Although it is proposed to give full play to students' imagination and let them think about how to exercise in their minds, most students will be limited by understanding and cannot meet the teaching requirements. Using animation to design courseware in teaching can intuitively complete the teaching task, so that the knowledge presented in the tutorial is no longer empty.
5. The combination of multimedia and tutorial system can improve students' self-exploration level and sense of success in learning, and can also guide students to surf the Internet correctly.
