When the letter of Guangdong physical booth manufacturers big promotion

In the classroom, in order to better achieve teaching objectives, the need to provide to the students as much as possible the specific image of picture data, such as illustrations, photographs, maps and so on. But the general picture is small, it is possible to zoom through physical booth clearly. 1, illustrations, photographs projected presentations, enrich students' perception. For example, in teaching "Hometown of monuments," a lesson by demonstrating Beijing's Badaling Great Wall, the Forbidden City, Xi'an mausoleum, terracotta, West Lake in Hangzhou, Anhui Huangshan pictures, rich perceptions of students, to stimulate students to love the motherland, thoughts and feelings of love for his hometown. 2, map projection demonstration, students of Reading Ability. For example, in teaching the "Hong Kong and Macao," a lesson, can projection demo Administrative Region of China and Hong Kong map diagram, according to the actual needs of the map can be enlarged, so that students in image and in small groups to talk about the geography and climate of Hong Kong. Such kind booth for the media, in order to map the main line, to guide students in the group to carry out cooperation in image analysis to explore other activities, take the initiative to obtain information about Hong Kong's natural geographic knowledge, which students demonstrate achievement of Reading Ability job to the students' work Physical booth to show results through feedback commenting on the screen, which is convenient and flexible, and it helps to improve the effectiveness of commenting. When the students complete the job, you can select the correct job and problematic exhibition for students to discuss the evaluation. Thus mobilize the enthusiasm of the students, to deepen the understanding of knowledge, they actively participate in the classroom, to consolidate and improve knowledge. Live and video in practical applications, we can kind of close-up lens to take down the booth, as an ordinary camera can zoom in while class cultural activities, will be transmitted to each student's performance on the screen for live broadcast, if In the video output terminal on the VCR connected to the stand will be able to program content recorded, the students see their own image presented to increase the endless fun on the screen to make the activity more vivid active. This feature is in teaching children better. Note the use of the process in question (a) teaching problem some teachers of the information, the use of arbitrary material, pay attention to the teaching of information processing and handling, although the use of physical booth this audio-visual equipment, but they ignore the teaching quality and purpose. Secondly, some teachers in the traditional blackboard writing can play freely, and in front of the booth was helpless kind, even I do not know how the blackboard. In fact, from a conventional projector development to physical booth, the biggest advantage is that we can direct writing on the blackboard, and reproduced on the projection screen in real time, which is kind of stand blackboard function; and, in teaching practice, some educational software although the picture vivid, expressive, but the lack of appropriate teaching sex; some thanks to ready-made picture or document, but the lack of theme; some teachers in the design of software, improper aspect ratio, it is difficult to show the whole; and Software uneven surface, flat screen, the projector is not ideal. So this requires multimedia class teacher before class fully prepared to collect educational information, materials, material processing depth and detailed, targeted, so that teaching can have a multiplier effect. (B) operation on Real booth is through the camera remake of methods to achieve pictures, documents, physical display. However, in practice, some teachers in the presentation, always like to put the whole page document all show up, so it is easy to create because the font is small and not clear, correct methods of operation should be focused on local presentations or zoom. Again, the larger your presentation page of a document or picture, can not all be displayed on the screen, so it should rotate the camera, adjust the focus, and then the rest of the show, but do not move the document or picture, unless it shows only a part. As another example, in the demonstration in kind, should be avoided whenever possible movement of objects, because objects in motion, the camera will be insufficient due to the fill light flickering phenomenon; In addition, due to the weak light, the required large aperture, the screen is easy mold burnt unclear. In general, when the shooting object is too bright or too dark, it will produce the screen brightness or color cast mold burnt phenomenon; not adjust the focal length, also makes the screen flickering, or too much contrast, or color distortion, etc. These the video shows the results for their own shortcomings caused. Multimedia classroom multimedia classroom by the basic composition of the multimedia computer, LCD projector, DVD, digital document camera, a central control system, projection screens, audio equipment, and other modern teaching equipment. (1) multimedia LCD projector is a multimedia presentation in the classroom throughout the most important and most expensive equipment, which is connected to a computer system, all of the video output system and digital document camera, the video, the digital signal output appears on the big screen. (2) Digital document camera can be objects, photographs, books and materials projection, is a very useful device. (3) The multimedia computer is the core of the demonstration system, educational software must be run by it, but also largely determine the quality of your presentation. (4) the projection screen. For supporting the use of the projector. Teaching function classroom presentations multimedia classroom teaching teachers in the classroom use of multimedia systems in the teaching content directly projected on a big screen, and teaching content to explain. Using this method to transmit information more intuitive, clear, can stimulate the senses from the audiovisual aspect of students, improve students' interest in learning, to enhance the students to observe the problem, understand the problem and the ability to analyze problems, to improve the teaching quality and efficiency. Simulation teaching multimedia technology can be sound, images, animation and other combine, simulate real-world scenarios and the macroscopic world of the microscopic world movement of things, to help students learn and understand some abstract principles and concepts. With the development of computer technology, there has been \ "; virtual reality \"; technology, which is to create a computer simulation of the environment, in this environment, students can serve as a practical operator through a variety of learning and operation, computer You can react and judgment. Simulation teaching system mainly computer equipment, servers and network devices. Multimedia classrooms Step 1, open the main power. 2. Power on the system. System power in the center console upper left corner, click to open. 3. Turn on the projector. The system uses the linkage mode, click the "Projector On" button to turn on the projector, and down the screen. 4. Turn on the computer. When the system monitor control signal by the control unit with VGA console control button to select "PC", the display connected to a computer signal, select the "booth" is displayed on the display booth signal. 5, open network classroom various other devices (such as monitors, projectors, and other in-kind. Detailed instructions for each device, with our other multimedia school classroom). 6. "Signal" button to let the projector search signal is not displayed on the screen if they want to show the contents, then click the "signal" button to let the projector and then search for the next signal. 7. After completed, the power of the computer, monitor, physical booth various devices turned off. Close attention is not immediately cut off the power supply after the projector to wait for the projector to cool fan running again after a period of time to stop off the main power. 8, power off the bench, post classroom staff acceptance.
