Analysis of the implementation of multimedia classrooms

I. Background of Multimedia Construction With the progress of the times and the development of science and technology, high school schools face new challenges in the management of modern information technology. In order to improve the school's own modern management standards, enrich teaching methods and means, improve the efficiency of the work of the organs, timely grasp all kinds of relevant information, improve the ability to handle various business and emergencies, strengthen management, have modern information technology means, use computer networks With communication technology, comprehensive, rapid and accurate information has become an urgent need for the internal management and teaching business of high school. The main hardware devices of the multimedia classroom are: multimedia LCD projector, electric screen, video booth, video recorder, DVD player, power amplifier, speaker, microphone, central control system, micro monitor, projector hanger, multimedia computer . The main function of the multimedia classroom: the central control system controls all devices through a wired console. Controllable equipment mainly includes: switch of projector, switching of film and computer signal; control of lighting; lifting of electric screen; switch of electric curtain; and switching of audio and video equipment; switch of switch machine, access box and Play and other operations. The multimedia classroom can be used by 100-200 people. The projector can put computer signals and video signals on the big screen, and can display it in kind through the film display stand. At the same time, powerful audio equipment can provide karaoke effects. Multimedia classroom master control system design: Second, the project situation analysis The multimedia classroom implementation site is 200 professional classrooms. According to the environmental requirements, the screen size required for the large screen projection required in the project is 150′′, and the brightness of the projector at 2200 ANSI lumens can ensure that the people in each seat can see clearly under sufficient illumination in the classroom. In terms of degree, it is necessary to consider both the financial factor and the microcomputer-based lectures. Therefore, it is recommended to use a model with a wide range of resolutions of 800x600 resolution. Therefore, in terms of resolution, it is necessary to consider the combination with the computer, and in terms of brightness. It is to make the human eye see more clearly without fatigue. From the engineering experience, EPSON 5600 model, brightness 2200ANSI lumens, resolution of 800x600, Chinese menu, partial amplification, multiple logos, etc., performance price is relatively high The warranty period is up to two years. The audio system in the multimedia classroom is based on voice reinforcement, supplemented by music sound reinforcement, and is mainly used as a teacher's lecture voice amplification output. The system uses high-performance audio equipment to quality and Durable as the principle, choose the mainstream models with higher performance and price. Central control system: Multimedia classrooms gather a lot of audio and video Equipment and demonstration equipment, in the conference or classroom, the operator not only has to complete the control of the equipment, but also complete the signal switching between the equipment. Therefore, it is required to select a complete set of functions, stable quality, convenient installation, simple operation, easy upgrade, good The performance and price ratio of the control system. Third, the system function introduction 1. The system can be clearly and timely to the students through the large screen projector: a.. computer signal, CAI teaching software and produced courseware; b. physical display Physical, text, graphics, pictures, slides and photographic negatives; c. Video recorders, educational programs on the shadow machine, and other video signals such as cable TV. 2. Fast and intelligent central control system for full image monitoring, easy The single-layer control interface allows you to flexibly control the following devices: projection equipment, audio equipment, computer, ambient lighting, screens, curtains, etc., with pre-monitoring, playback, control and other functions to help you save more time, manpower And material resources, effectively improve work efficiency. 3. Hold various multimedia conferences 4. Play movies and other entertainment on weekends Programs, and can hold small and medium-sized cultural concerts, make full use of resources, enrich the school's extracurricular cultural life. 5. Teachers use high-fidelity wireless microphones to teach lesson, especially in the group class, can be more prominent Teaching in any part of the classroom, so that teachers and students can be integrated into one, which can do more with the improvement of students who cultivate high-quality students and improve the quality of teaching. 6. Monitor the venue through the scene camera function of the film showcase [1] There are 40 students in the class, including 29 boys. All but one of the students from the city are from Northern Jiangsu. These students have not achieved satisfactory academic results, but their thoughts are simple and enterprising. The basic goal of this class is to establish An enterprising team with strong ability and ability, all students can establish a clear learning purpose, form a good learning atmosphere; cultivate students' good behavioral norms, promote integrity, and gradually form a discipline that is disciplined, enterprising and diligent wind. Second, specific measures: 1, do a good job of class one day routine, put an end to the phenomenon of late absenteeism, do a good job of self-study discipline, improve efficiency. 2. Improve the quality of newspapers and posters, create a good learning atmosphere, and build a good class culture. 3. Use class publications to educate students, give play to students' subjective initiative, and motivate students. 4. Organize class activities to cultivate students' collective ideas and enhance class cohesion. 5. Conduct regular learning activities to develop students' good learning attitudes and methods. 6. Conduct beneficial cultural and sports activities to promote the healthy development of students' physical and mental health. 7. Organize students to actively participate in various activities of the school and strive to achieve good results in various activities. 8. Regularly communicate with students to understand the students' ideological dynamics and promptly solve problems for students. Third, the event arrangement: the first week: the second week: celebrate Teacher's Day. Week 3: Students register, arrange student accommodation and living issues, and attend the school opening ceremony. The fourth week: select team cadres, formulate class and group activity plans, and strengthen routine management regulations. Theme class meeting: self-introduction and entrance feelings. Week 5: Theme Class Meeting: Welcome National Day Cultural and Entertainment Festival. Week 6: Form a class sports team to meet the school sports meeting. Week 7: Class debate. The eighth week: the mid-term examination mobilization, examination and discipline education. Week 9: Review the exam. Week 10: Midterm exam. The eleventh week: the mid-term exam is lost. Week 12: Social Practice. Week 13: Theme class meeting: special show. The fourteenth week: the celebration of the 1st and 9th. Week 15: Conducting the study of party constitutions.
