Problems solved by technology
Existing multimedia display screens are usually installed separately on one side of the blackboard and used in conjunction with the blackboard. Since the display screen has no protective measures and is exposed to the outside, it will be damaged by accidental touch and occupy space, affecting the activities of teachers and students in the classroom. Moreover, the existing blackboard needs to erase the chalk dust on the surface after writing, which is time-consuming and laborious, and the erased chalk dust is not easy to collect, and it is scattered in the indoor air to affect the air quality, which is harmful to the respiratory system of teachers and students. , in view of this, we propose a teaching blackboard for Chinese language and literature teaching and its use method
