Description

Diversified Japanese teaching is with writing board

Technical Field

The invention belongs to the field of Japanese teaching, and particularly relates to a writing board for diversified Japanese teaching.

Background

Along with the acceleration of globalization process, japanese is more and more valued by people as an important foreign language communication tool, and in the japanese teaching process, a writing board is a very common and very important teaching tool.

Traditional clipboard produces a large amount of chalk dusts when using the chalk to write the teaching, pollutes the teaching environment, causes serious influence to teacher and student's health, and because of clipboard surface is smooth, easily appears reflecting light or light dim scheduling problem, leads to the student to be difficult to discern the content on the clipboard, reduces the quality of teaching, is unfavorable for the teaching of pluralism Japanese.

To this end, we propose a diversified japanese teaching writing board to solve the above problems.

Disclosure of Invention

The invention aims to provide a diversified writing board for Japanese teaching, which can prevent chalk dust from flying and has high identification degree, aiming at the problems that the chalk dust pollutes the teaching environment and students are difficult to identify the writing contents.
