I am teaching grade 3 Chinese students. I gave them a dictation this morning - only requiring them to write down the letters as I spell them, and not to know how to spell words - and find a number of common problems with all of them. For example, "m" and "n" - half of the students do not hear the difference. "g" and "j" are also difficult for them. "b" and "p" and "e" - all having the same sound.
Any suggestions for helping them? I think this problem is going to haunt them unless it is corrected.
