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 change, and relates to the technical field of Internet teaching. The Internet teaching device based on sliding resistancechange comprises a wall body, a blackboard is fixedly mounted at the right end of the wall body, sliding grooves are fixedly formed in the upper side and the lower side of the blackboard at the rightend of the wall body, rolling wheels are connected into the sliding grooves in a rolling mode, an electronic whiteboard is fixedly mounted at the right ends of the rolling wheels, electric shock pliers are fixedly mounted at the top end of the electronic whiteboard, and a connecting rod is fixedly mounted at the bottom end of the wall body. According to the Internet teaching device based on sliding resistance change, the combination of traditional teaching and Internet teaching is realized, the teaching quality is improved, the self-adjustment of a projector is realized, the cross use of twosides of the blackboard is more convenient and faster, the projector can be contracted and placed upwards, the space is saved, the touch of the projector is avoided, and the calibration of the projection direction of the projector is also facilitated.
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 ...
