Multimedia technology is not a simple combination of various information media. It is an information technology that combines information in the form of words, graphics, images, animations and sounds, and is comprehensively processed and controlled by a computer, which can support a series of interactive operations. The development of multimedia technology has changed the application field of computers, which has changed computers from special products in offices and laboratories to ordinary tools in the information society, and has been widely used in industrial production management, school education, public information consultation, commercial advertisements, military command and training, and even family life and entertainment.
In recent years, modern technology has been widely used in teaching. With the development of microcomputers and the sharp drop in prices, crisis has gradually become the main means of modern technical education with its unique functions and characteristics. Multimedia teaching software is also emerging one after another, but there are still some shortcomings if we rely entirely on general courseware. For example, Kelihua's teaching software has no courseware for political courses. Moreover, due to the differences of students in different schools, although the software design has universal adaptability, it is not targeted enough. Therefore, at present, teachers are actively learning to make courseware and apply multimedia to assist teaching.
The disadvantages of the traditional "teacher-language-student" teaching model are increasingly obvious. Multimedia-assisted teaching can make up for the lack of teachers' ability and is a rare good helper. Moreover, in various course evaluations (such as last semester's open competition), whether to use multimedia has become an important measure. I thought there was no need to play tricks in politics class. After reading the multimedia-aided lesson plan of Hong Chau, a teacher in Wuhan No.2 Middle School, I suddenly realized that politics can still be taught in this way. This led to some thoughts on multimedia teaching, which are summarized as follows:
First of all, the use of multimedia can easily create realistic situations, thus activating the brain and making students have a strong interest in participation. Educational psychology believes that the most realistic and active component of learning motivation is cognitive interest, or curiosity. Middle school students like new forms and new teaching methods, which make students feel fresh and interesting. When talking about "improving the economic benefits of enterprises", students are very familiar with the issue of economic benefits. It seems that the bankruptcy of laid-off enterprises is a manifestation of poor economic benefits of enterprises, and students easily give up "knowing what it is" because they don't have a good grasp of teaching methods in actual teaching. Therefore, when making courseware, we can start with interest, cite several colorful and interesting examples of enterprises and the infiltration of subject knowledge, create a situation for students, attract students' attention, let students choose a work unit, be an investor and be a big entrepreneur, and feel the importance of improving economic benefits from different angles.
Secondly, the use of multimedia is conducive to expanding the educational space, providing students with a lot of information and meeting various needs. Facts speak plainer than words. In today's society, counterfeiting is becoming more and more complicated. Students don't believe hearsay, but believe that seeing is believing. The local economic phenomena that students come into contact with may not correctly reflect the essence of things. This requires a lot of examples to help explain. When "improving the economic benefits of enterprises", the conventional method is to use tabular data, and there are many examples, which need nearly 3 class hours, while using multimedia only needs 1 class hour, which is easy to break through the difficulties. Teachers can show China's achievements since the reform and opening up: the return of Hongkong and Macao, and the celebration of the 50th anniversary of the founding of the People's Republic of China. At a glance, video and data are condensed into one picture. If the song "The Story of Spring" can be used to set off a thriving scene, it will be more obvious that all this comes from the improvement of economic benefits. By this means, students will be deeply impressed, and the persuasiveness of facts will not be reduced because of the teacher's limited language expression ability.
In addition, when teaching political knowledge, we can also use the knowledge of other disciplines to explain, so as to attract students with special skills in various courses to concentrate on thinking, that is, to win the recognition of students in expanding the scope of praise and make them willing to express themselves in political classes. After all, we are still facing a group of older children, and the recognition of teachers and classmates can give them great encouragement. For example, in the course of "improving economic benefits", we can use the stress diagram of analyzing things in physics to explain Haier's "slope sphere theory" in management experience, and use simple animation in Powerpoint to attract students. At the same time, we can also use the simple calculation of the maximum and minimum in mathematics to digitize the seemingly boring theory, and guide students to find the intersection between disciplines, so as not to relax their study of a certain discipline easily.
Use various ways, methods, equipment, theories, etc.
Educating the next generation with modern teaching equipment, modern ideas and methods is more inclined to think and think.
It is different from the traditional educational model.
