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是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。如今时代在不断前进，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.
80年代时，教室墙上的水泥黑板是很普及的，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.
到了九十年代，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，粉笔灰尘亦会到处弥漫，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.
到现在的黑板用彩涂钢板，复合材料板....这见证了世界教育事业的一步步发展。佛山市万庆物资有限公司应用于黑板的彩涂钢板板面，采用涂以耐磨涂层的优质合金钢板,板面厚度多为0.3mm-0.4mm,耐磨,不脱落,不褪色,经久耐用.书写手感好,字迹清晰,易写,易擦试.粉尘少，而新型材料复合板是由进口高分子合金颗粒与环氧树脂经一次性压制成型表面不做任何处理，板面厚度为3mm，书写流畅，字迹清晰永久性不打滑，不反光，擦后无残留，可视效果极佳，经测试使用寿命达15年以上， 平面板板面平整光滑，弧面板板面为曲面,防止反光,能使坐在各角落的学生也能看清板书字迹,适用于较大的教室。
To the current blackboard with color coated steel plate, composite board.... this has witnessed the step by step development of the world education cause.Foshan Wanqing Materials Co., Ltd. is applied to the blackboard color coated steel plate surface, using high-quality alloy steel plate coated with wear-resistant coating, the plate surface thickness is mostly 0.3mm-0.4mm, wear-resistant, do not fall off, do not fade, and durable. Good writing feel, clear handwriting, easy to write, easy to try. Is less dust, and the new material composite plate by imported polymer alloy particles and epoxy resin by pressing surface without any treatment, surface thickness of 3mm, smooth writing, clear permanent not skid, not reflective, wipe no residue, excellent visual effect, tested service life of more than 15 years, flat panel flat surface, curved surface, prevent reflection, can make sitting in each corner of students can also see handwriting, suitable for a larger classroom.
现在，黑板已经不是传统意义的黑板了，交互式纳米智能黑板、液晶屏、iPad、AR实景…… 层出不穷的新科技伴随着全新的育人理念，让教与学更加便捷。
Now, the blackboard is no longer the traditional meaning of the blackboard, interactive nano intelligent blackboard, LCD screen, iPad, AR real scene... emerge an endless new technology with a new education concept, make teaching and learning more convenient.
