Improving Spelling in the Classroom
Incorrect spelling may often give the reader the impression that the writer is careless and lacks education.
One should try and remember that spelling is often very difficult for students studying English because of the lack of correlation between the sound of a word and how it is actually spelled.
When you find students working with different phonemes, you should attempt to draw their attention to the various different spellings and pronunciations of those phonemes.
When students discover new words you can also go on further to ask them any other words that they might know with a similar spelling or sound.
Remember to teach your students the most important spelling rule of all: When in doubt, ask or look it up! But ask first – its quicker!.
Another issue is the fact that there are differences between the spelling and pronunciation of British English and American English.
Extensive reading is another very important way for students to improve their spelling.
