since nursery till college ,,chalkboards are there,evev on offices ,or seminars,,this is used,it is very useful and helpful to those schools without computers and enough books for everyone ,coz the teacher just write those important words or lessons in the chalkboard.
now the technology is producing projectors,,many have tried to used this instead of chalkboards..like in our edtech class..but it doesnt mean that we will reject the chalkboards,,of course we still will used that,this projectors are easy to used and faster than wring those things in board..but how about those schools who can not afford to buy the projector,,,,? of cousre...hello chalkboard....hehhehee
