     There is a common belief among parents that schools are no longer interested in spelling. No school I

have taught in has ever considered spelling unimportant as a basic skill. There are, however, quite

different ideas about how to teach it, or how much priority (优先) it must be given over general language

development and writing ability. The problem is how to encourage a child to express himself freely in

writing without holding him back with spelling.

     If spelling becomes the only point of his teacher's interest, clearly a bright child will be likely to "play

safe". He will write only words within his spelling range. That's why teachers often encourage the early

use of dictionaries and pay attention to content rather than technical ability.

     I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience: "This work is terrible! There are far too many spelling mistakes." It may have been a sharp criticism of

the pupils' technical abilities in writing, but it was also a sad thing for the teacher who had omitted (略过)

to read the composition, which contained some beautiful expressions of the child's deep feelings. The

teacher was not wrong to draw attention to the mistakes, but if his priority had centered on the child's

ideas, an expression of his disappointment with the presentation would have given the pupil more hope to

seek improvement.
