confidently in writing without holding him back with the complexities of
spelling. If spelling becomes the only focal point of his teacher’s interest, clearly a bright child will be likely to "play safe". He will be prone to write only words within his spelling range, choosing to avoid adventurous language. That’s why teachers often encourage the early use of dictionaries and pay attention to content ra A. the difficulties in teaching spelling. B. the role of spelling in general language development.
