Teaching display device for improving understanding ability of old people

Abstract

The invention discloses a teaching display device for improving the understanding ability of old people. The teaching display device comprises a reverse erasing, collecting, dust-raising preventing and recycling interesting interaction device, a writing and displaying combined device, a multimedia learning interaction screen overturning and storing device, a writing and displaying combined screen rotating device, an automatic height adjusting device and a convenient and intimate auxiliary device. The invention belongs to the technical field of teaching appliances and particularly relates to the teaching display device for improving the understanding ability of the old people, aiming at the technical problems that an existing teaching display device erases chalk dust from the outside and dust flies around after erasing, a reverse thinking method that a blackboard eraser does not move and a blackboard moves is adopted, and according to the asymmetry principle, an automatic opening and closing magnetic dust-raising preventing assembly is creatively arranged, the technical prejudice in tradition that blackboard erasing can be achieved only by moving the blackboard eraser is overcome, and the technical effects that the blackboard is erased internally and chalk dust is conveyed and collected in a raising-preventing mode can be achieved only by moving the blackboard.

Description

technical field [0001] The invention belongs to the technical field of teaching aids, and specifically refers to a teaching display device for improving the comprehension ability of the elderly. Background technique [0002] Teaching equipment is a general term for all kinds of equipment used to enable students to intuitively and visually understand the teaching content and the equipment used by teachers in teaching. Teaching aids can improve students' interest in learning, enrich perceptual knowledge, help form clear concepts, and develop students' observation and thinking abilities. Most of the existing teaching display devices adopt a fixed structure, which cannot be moved or rotated, and the structure is simple, the function is single, unsystematized, and humanized adjustment cannot be performed. Ergonomic principles are less considered, and the adaptability is poor, which has certain limitations. In addition, when teaching chalk writing on the blackboard, it is easy to...

Problems solved by technology

Most of the existing teaching display devices adopt a fixed structure, which cannot be moved or rotated, and the structure is simple, the function is single, unsystematized, and humanized adjustment cannot be performed. Ergonomic principles are less considered, and the adaptability is poor, which has certain limitations. In addition, when teaching chalk writing on the blackboard, it is easy to generate a lot of dust, pollute the environment, and endanger the health of teaching and listening personnel.
