Key points of blackboard selection:
A, indelible, easy to erase the blackboard should have a durable paint, do not fade, do not reflect light, and should have a dust box, to facilitate dust cleaning, to prevent the impact on the environment, to ensure the health of teachers and students.
Second, more choices of flat blackboards With people's demand for dust-free environment, flat blackboards began to be favored by schools. Matte beige board is helpful for many dust-free teaching. When using this blackboard, the water-based writing pen replaces chalk, which eliminates the influence of dust and can be recycled, which not only improves the environment, but also saves money. There are a variety of cleaning liquids and writing liquids to choose from.
Third, large classrooms choose curved blackboards. Curved blackboard has both the advantages of traditional blackboard and its own characteristics. For example, the curved shape can meet the needs of the classroom, and no matter how many students can't reflect light, the blackboard can't be seen because of the angle, which affects the learning effect.
