Spelling Mastery Robert Dixon, Siegfried Engelmann, Mary Meier, Donald Steely and Tina Wells This highly successful Direct Instruction programme turns the mystery of spelling into mastery. Spelling Mastery provides pupils with reliable spelling strategies that enable them to spell accurately and with confidence. Spelling Mastery emphasises learning to spell by generalisation rather than by the weekly memorisation of word lists, integrating three fundamental approaches to spelling: Phonemic: Helps pupils to spell words that are highly regular in terms of sound-symbol correspondence. Morphemic: Teaches older children to spell a variety of prefixes, suffixes, and word bases, and provides them with a manageable set of rules for combining these elements. Whole Word: Helps pupils to tackle high-frequency words that must be learned by memory.
