Problems solved by technology
[0003] Although Internet teaching has the advantages of high efficiency, speed, and convenient dissemination, it can only display the information in the downloaded courseware and cannot be effectively modified. Therefore, it still needs to be combined with traditional teaching methods, but the existing Internet teaching devices cannot easily realize Combining with traditional teaching, and in the process of using the projector to teach, the projector cannot be adjusted for contraction and angle, which makes the projector easy to occupy indoor space and cannot be effectively calibrated

The invention provides an Internet teaching device based on sliding resistance changes, and relates to the technical field of Internet teaching. The Internet teaching device based on sliding resistance changes includes a wall, a blackboard is fixedly installed at the right end of the wall, chutes are fixedly installed on the upper and lower sides of the blackboard at the right end of the wall, and rollers are scrolled inside the chute. An electronic whiteboard is fixedly installed on the right end of the roller, an electric contact clamp is fixedly installed on the top of the electronic whiteboard, and a connecting rod is fixedly installed on the bottom end of the wall. The Internet teaching device based on sliding resistance changes realizes the combination of traditional teaching and Internet teaching, improves the quality of teaching, realizes the self-adjustment of the projector, and is more convenient and quick for the cross use of both sides of the blackboard, making the projector It can be retracted and placed upwards, which saves space, avoids touching the projector, and facilitates calibration of the projection direction of the projector.
Description
technical field [0001] The invention relates to the technical field of Internet teaching, in particular to an Internet teaching device based on sliding resistance changes. Background technique [0002] Internet teaching is a new form of education that combines Internet technology and education with the continuous development of today's science and technology. Information technology has penetrated into all aspects of society. In the field of education, an information-based disruptive change It is happening quietly. In the modern information society, the Internet has the characteristics of high efficiency, fast and convenient communication, and plays an irreplaceable important role in the study and life of primary and middle school students. [0003] Although Internet teaching has the advantages of high efficiency, speed, and convenient dissemination, it can only display the information in the downloaded courseware and cannot be effectively modified. Therefore, it still needs ...
