Problems solved by technology

[0002] At present, classroom teaching generally relies on the blackboard to show students the course content intuitively, and write with chalk. When the blackboard is filled with chalk dust, you need to use a blackboard eraser to wipe off the chalk words. Writing with chalk will easily produce a certain amount of dust. Long-term inhalation of these dusts is an important factor affecting the health of teachers and students who stand in front of the blackboard for teaching work
