Problems solved by technology

The commonly used method is usually to project the electronic courseware onto the blackboard of the podium through a projector. At this time, writing on the blackboard is easy to overlap with the projection, which affects viewing and learning. Since the projection occupies the area of ​​the blackboard, teachers need to write on the blackboard where there is no projection. Due to the reduced area, it is necessary to repeatedly wipe off the written content to carry out teaching smoothly. For some students who write slowly, it may affect their timely recording of note information, affect the teaching effect, and cannot fully meet the teaching needs of teaching. In addition, The structure and function of this kind of teaching device is too single, and the operation table is not easy to move. When it is necessary to take students to the outdoors for teaching, it is inconvenient to use and is not conducive to the progress of teaching.
