在教學過程中，老師們每天幾乎都要用到黑板，我記得我那個時代的黑板是用黑色或者墨綠色涂料涂抹在木板，水泥等堅硬物體表面使用。如今時代在不斷前進，黑板也從木質“板”到水泥“板”到如今的多媒體交互式納米智能黑板。從以前小小的課桌到現在的多媒體教學，這是過去我們做夢也不敢想的，如今都已經實現。

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年代時，教室墻上的水泥黑板是很普及的，相對木質黑板來說不易損壞，平面抹得也更光滑了，老師寫字的時候相對容易，但是學生看板書，又出現了新問題，那就是黑板容易反光——坐在教室兩側的學生，根本看不清黑板上的字，所以要睜大眼睛，扭著身子和腦袋，找最佳的角度。如果黑板表面的黑漆掉光，坐在后排的學生，又大多看不清楚了。水泥黑板挺好用，寫起字來很清楚，但學生們在黑板飄散的粉筆灰中上課，老師的衣服和書包有時候會沾上白茫茫的一層。

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，很多學校都用上了毛玻璃的黑板，這種黑板比較細膩，比木制黑板、水泥黑板好多了，書寫順暢一些，學生也看得清楚些，但是擦黑板的時候，粉筆灰塵亦會到處彌漫，直往人鼻孔里鉆，當時不少老師都因此得了咽喉炎。

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.

到現在的黑板用彩涂鋼板，復合材料板....這見證了世界教育事業的一步步發展。佛山市萬慶物資有限公司應用于黑板的彩涂鋼板板面，采用涂以耐磨涂層的優質合金鋼板,板面厚度多為0.3mm-0.4mm,耐磨,不脫落,不褪色,經久耐用.書寫手感好,字跡清晰,易寫,易擦試.粉塵少，而新型材料復合板是由進口高分子合金顆粒與環氧樹脂經一次性壓制成型表面不做任何處理，板面厚度為3mm，書寫流暢，字跡清晰永久性不打滑，不反光，擦后無殘留，可視效果極佳，經測試使用壽命達15年以上， 平面板板面平整光滑，弧面板板面為曲面,防止反光,能使坐在各角落的學生也能看清板書字跡,適用于較大的教室。

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.

現在，黑板已經不是傳統意義的黑板了，交互式納米智能黑板、液晶屏、iPad、AR實景……　層出不窮的新科技伴隨著全新的育人理念，讓教與學更加便捷。

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.
