Premye imen yo te dekouvri ke chabon te kapab itilize pou penti. Depi lontan anvan envansyon ekriti, moun te itilize chabon pou pentire. Toner ou chabon murales ka toujou wè nan twou wòch Ewopeyen yo.
Nan Mwayennaj yo, moun yo te kòmanse dekouvri ke lacho ak dlo te kapab itilize pou fè blòk -objè ki gen fòm, ki te kapab anrejistre sou sifas nwa oswa difisil lè l sèvi avèk metòd ki sanble ak plim chabon.

Therefore, in Europe and the United States, the original teaching method began to be widely used. Small, non-stationary black bulletin boards have been enlarged for teaching purposes to facilitate remote students to copy the teacher's dictation.
