The use of multimedia teaching in modern teaching is a requirement of the times. But how to do the right application and play its role is an important topic that our frontline teachers are trying. Teachers must first go beyond the misunderstanding of multimedia in classroom teaching applications, simply think of "teaching materials moving", or turn the original "blackboard + chalk" into "screen + computer", regardless of whether the situation involved is in line with teaching Whether the content needs highlight the teaching focus and break through the teaching difficulties. Secondly, it is necessary to clarify that the application of teaching media is not a form, but a new teaching aid that helps us to start from the teaching needs, to improve students' ability, to realize the new curriculum concept, and to make new achievements.
First, the use of teaching multimedia, can be abstracted to specific, reducing the cognitive difficulty of students
Any abstract mathematical concept is formed in the process of formation, but is often based on a large number of specific objects, or based on some relatively specific abstract concepts. The use of advanced teaching equipment such as slides, projectors, and teaching media in teaching can accelerate the modernization of teaching methods, and is also an important way to implement the teaching principles of combining abstraction and intuitiveness.
At the right time, using the rich expressive power of multimedia courseware, not only can we vividly express the colorful world of audiovisual, but also simulate microscopic things, vividly and intuitively express abstract things, simplify and reproduce complex processes. . According to different teaching contents, making full use of sound, animation, video and other multimedia means, static can be turned into dynamic, abstracted into an image, fully expressing the teaching content, and breaking through the teaching difficulties.
Second, the use of teaching multimedia can speed up the teaching rhythm and improve teaching efficiency
The new textbook proposes the task of learning a fairly comprehensive basic knowledge with less class hours, and also pays attention to reducing the student's academic burden. I believe that teachers are not competent to update teaching concepts, methods and techniques. As an advanced teaching aid, multimedia technology has an unparalleled advantage compared with the traditional “blackboard + chalk†teaching mode. It can present a large amount of information arbitrarily and quickly, and stimulate information by stimulating students' senses. The transmission channel improves the speed of information transmission and increases the density of information transmission. With its unique functions of text, sound, image, animation, etc., the classroom teaching is more vivid and vivid, and it is easier to highlight the key points, resolve the difficulties, and obtain the previous tradition. The effect that teaching aids can't achieve.
Third, the use of teaching multimedia, can highlight key points, break through the difficulties
Teaching courseware can be divided into demonstration courseware, simulation courseware, practice courseware, and game-type courseware. In the classroom, there are often phenomena and processes that prevent teachers from being clear in the classroom, and these are often the most difficult points in mathematics teaching. At this time, using the intuitiveness of the teaching media, we can break through the limitations of students' vision, observe and analyze from multiple angles, highlight key points, and break through the difficulties. The use of the dynamic nature of the teaching media is conducive to reflecting the concepts and processes, and the images and sounds are similar, mobilizing the students' emotions, attention and interest. Use the repeatability of the teaching media to overcome forgetting and highlight key points. Using the experimental nature of the teaching media, the expansion of ordinary experiments can be realized, and the students' exploration and creativity can be cultivated through the reproduction and simulation of real situations.
Fourth, the use of interactive multimedia interactive functions, can be adjusted in a timely manner
We all know that the most effective computer is the powerful interactive function. Teachers should design an appropriate software platform, so that students can use the software platform to engage in activities such as exploration or practice, which can realize personalized teaching and monitor the learning effect of students at any time. The teaching is more targeted, and it can also change the way of learning. In today's Internet, teachers try to learn under the network is the direction we need to explore. Our school has realized the school communication. In the teaching, in many cases, I can arrange the exercises in time, check the preparations of some students as soon as possible, and further adjust and control based on these feedbacks.
Teachers should try their best to create conditions for students to explore, operate, and communicate with each other. To this end, efforts should be made to enhance the interactivity, adaptability, and operability of teaching courseware, and to guide students through the application of courseware to make the learning process a "rediscovery" and " The process of re-creating. In this way, students not only experience the process of exploring knowledge, but also master the knowledge. More importantly, they realize how to solve new problems with the knowledge they have already mastered, and their mathematical thinking ability has been improved.
In short, with the deepening of the new curriculum reform, the focus of mathematics education has also evolved from a simple study of the "teaching" method to a broader study of the "study" method. How do teachers integrate the information technology and the blackboard in mathematics teaching, organize each class, activate each class, activate students' curiosity and curiosity in mathematics, and enable students to generate motivation for learning and research.
