VOD video on demand electronic lesson preparation, courseware production 16 times optical zoom + 4 times electronic zoom
Picture and text scanning function
Whiteboard real-time writing function Network remote teaching function Video conferencing function
Digital hard disk recording function Network integrated teaching instrument with multiple functions:
Traditional multimedia classrooms have many equipments, complex operations, and difficult maintenance and security. The network integrated teaching instrument is simple and convenient to operate, stable and reliable. The installation of a network integrated teaching instrument can achieve the following points:
1. The network integrated teaching instrument creates a good classroom multimedia teaching effect for teachers. The network integrated teaching instrument is the only operation platform for teachers in the classroom, which enables teachers to get rid of the traditional teaching method of "chalk + blackboard". The simple operation uses multiple multimedia technologies, which is conducive to the optimal design of teaching and learning processes and resources.
2. The network integrated teaching instrument can build a good teaching interactive environment. Teachers can make full use of the rich resources of the teaching information resource library through the network integrated teaching instrument, design a reasonable teaching method, and put the courses that students need to preview or self-study on the Internet for students to choose and browse freely after class. Under the organization and guidance of teachers, students can use the learning resources and environment created by the network integrated teaching instrument to give full play to their initiative, enthusiasm and initiative in learning.
3. Network integrated teaching instrument can provide advanced technology platform for distance teaching practice. Its digital video conference function can realize distance education, and can also realize real-time "big classroom" teaching across classrooms, classes, colleges and regions, and realize the "global village school" of learners. Let students communicate "face-to-face" with teachers in an open environment.
The network integrated teaching instrument is different from the traditional multimedia equipment:
1. The difference from the booth: the network integrated teaching looks like a booth, but in fact its core is an embedded computer, which has multiple functions such as network teaching, video conferencing, on-demand, electronic whiteboard and teacher preparation, courseware presentation and so on. In the teaching process, teachers can perform video-on-demand, use various teaching software, and also make full use of the teaching information resource library to search, develop, organize, collect and produce teaching multimedia courseware on the Internet, and can realize remote teaching for the construction The teaching practice under the guidance of doctrine provides a virtual campus.
2. Difference from computer: The network integrated teaching instrument has the image acquisition and transmission function of the booth. For small objects, models, pictures, and charts, it can be converted into an image signal through the network integrated teaching instrument, and processed by zooming in and out, which is fast , Real-time, intuitive display. Using teaching information materials, film and television materials, three-dimensional animation and even mathematical modeling, you can turn some esoteric abstractions or knowledge points that are difficult to perceive in reality into vivid and vivid audio-visual pictures or models, so as to be "immersive" Way to teach students. It not only exerts the network characteristics of the computer, but also the individuality of the network integrated teaching instrument on the terminal, which meets the specific needs of classroom teaching.
The network integrated teaching instrument has the characteristics of integration and network:
1. Integration: There are many traditional multimedia classroom equipment. The network integrated teaching instrument realizes the high integration of multimedia teaching equipment. It integrates the functions of multimedia computers, video booths, power amplifiers and other equipment necessary for traditional multimedia classrooms.
Teachers can make full use of the teaching information resource database in the entire process of teaching design and teaching preparation to search, develop, organize, collect and produce teaching multimedia courseware on the Internet to optimize teaching design. Through it, teachers can perform video on demand, use various teaching software, multimedia courseware and any teaching materials on the campus network. The image acquisition and display transmission function of the booth saves the tedious production process of slides and slides, and for the slides and projection materials that need to be used continuously, the network integrated teaching instrument can also continue to be used. The highly integrated network integrated teaching instrument reduces construction investment, simple operation procedures, and reduces the maintenance of professional maintenance personnel. More than 110 multimedia classrooms in the Naval Aeronautical Engineering College need only be equipped with a professional maintenance technician.
2. Networking: The application of network integrated teaching instruments in teaching practice breaks through the limitations of traditional teaching time, space, micro and macro, effectively utilizes the network and teaching information resource library, and builds interactive for teaching and teacher-student communication surroundings. The digital video conferencing function of the network-integrated teaching instrument can enable learners from thousands of miles to easily and quickly access the real-time classroom learning in the school at any time through the computer, realize network remote classroom teaching, and also realize cross-classroom, cross-class, cross-school Real-time "big classroom" teaching in schools and across regions, realizing the "global village school" of learners, and the scenes of each teaching site will be smoothly interacted together in real time, so as to achieve a large-scale "large classroom" teaching. The network integrated teaching instrument connects the classroom teaching system with the teaching management system, the teaching information resource database system, the virtual teaching system, and the distance teaching, and constructs an e-structured teaching information environment to truly realize digital teaching and networked learning.
As long as the ordinary classroom is equipped with a network integrated teaching instrument, LCD projector, and a pair of speakers, it is easy to transform the traditional classroom into a multimedia classroom with integrated functions such as multimedia presentation, video display, and network services. In addition, the innovation of the network integrated teaching instrument is mainly reflected in: leading design ideas and reasonable overall structure. It can not only realize classroom teaching, lesson preparation, material collection, network remote teaching, but also has excellent technical compatibility and scalability. The use of advanced semiconductor cooling technology and a series of other measures ensure the reliability and stability of the network integrated teaching instrument on the basis of high integration.
Since September 2000, Beijing Yicheng Zhiyuan Technology Development Co., Ltd. has built 1,600 multimedia classrooms using network integrated teaching instruments. Teachers have changed their concepts from lesson preparation to teaching, from homework assignments to exams, and their enthusiasm for using modern teaching methods has never been higher. The students took the initiative to accept this teaching model, and they actively participated in online learning in and out of the classroom. In the course of more than three years of teaching practice, the teaching environment constructed by the network integrated teaching instrument has been widely praised by teachers and students.
