Although with the development of technology, electronic whiteboards have rapidly emerged, leading to the gradual replacement of blackboards by electronic whiteboards, writing with chalk and whiteboard pens still plays a vital role in teaching. Teaching is a human-specific talent training activity consisting of teachers' teaching and students' learning. Through this activity, teachers guide students to learn and master cultural and scientific knowledge and skills in a purposeful, planned and organized manner, promote the improvement of students' quality, and make them people needed by society. Blackboard does not specifically refer to a black board. In the traditional sense, it is a plane that can be written on repeatedly. The board surface is hard and is mostly used for education.
