在教学过程中,老师们每天几乎都要用到黑板,我记得我那个时代的黑板用黑色或者墨绿色涂料涂抹在木板,水泥等坚硬物体表面使用。如今时代在不断前,黑板也从木质“板”到水泥“板”到如今的多媒体交互式纳米智能黑板。从以前小小的课桌到现在的多媒体教学,这是过去我们做梦也不敢想的,如今都已经实现。

During the teaching process, the teachers used the blackboard almost every day. I remember that the blackboard of my time was applied with black or dark green paint on the surface of the boards, cement and other hard objects.Today, The Times are constantly moving forward, and the blackboard is also moving from wooden "board" to cement "board" to today's multimedia interactive nano-intelligent blackboard.From the former small desk to the current multimedia teaching, this is what we could not dream of in the past, and now it has been realized.

白板笔书写板

80年代,教室墙上的水泥黑板很普及的,相对木质黑板来说不易损坏,平面抹得也更光滑了,老师写字的时候相对容易,但是学生看板书,又出现了新问题,那就是黑板容易反光——坐在教室两侧的学生,根本看不清黑板上的字,所以要睁大眼睛,扭着身子和脑袋,找最佳的角度。如果黑板表面的黑漆掉光,坐在后排的学生,又大多看不清楚了。水泥黑板挺好用,写起字来很清楚但学生们在黑板飘散的粉笔灰中上课,老师的衣服和书包有时候会沾上白茫茫的一层。

In the 80s, the cement blackboard on the classroom wall is very popular, relatively wood blackboard is not easy to damage, plane is more smooth, the teacher to write relatively easy, but the students reading board, a new problem, that is the blackboard easy reflective —— students sitting on both sides of the classroom, can't see the words on the blackboard, so to open your eyes, twist the body and head, find the best Angle.If the black paint on the surface of the blackboard disappears, most of the students sitting in the back row can not see clearly.The cement blackboard is very easy to use, write very clear, but the students in the floating chalk ash in the blackboard class, the teacher's clothes and bags are sometimes covered with a vast white layer.

九十年代很多学校都用上了毛玻璃的黑板,这种黑板比较细腻,比木制黑板、水泥黑板好多了,书写顺畅一些学生也看得清楚些,但是擦黑板的时候,粉笔灰尘到处弥漫,直往人鼻孔里钻,当时不少老师都因此得了咽喉炎。

In the 990s, a lot of schools use the wool glass blackboard, the blackboard is delicate, much better than the wooden blackboard, cement blackboard, smooth writing, the students also see clearly, but wipe the blackboard, chalk dust will be everywhere, straight into the nostrils, many teachers got the throat.
