Many authorities classify most, if not all, methods of teaching reading into two broad groups on the basis of the psychological processes involved : ‘synthetic methods’’ and ‘analytic methods’. A third group is often included-namely, ‘analytic-synthetic methods’-which combines certain elements of the first two... This may be readily explained. Some interpreted the terms, ‘analytic’ and ‘synthetic’ according to particular philosophies. As defined by the authors of the report, however, the term, ‘synthetic’, referred to the mental process of combining the detailed elements of language (the sounds of letters and of syllables) into larger units (words, phrases and sentences), and the term, ‘analytic’, referred to the mental process of breaking down these larger units into their constituent elements. If restricted definitions are accepted and strictly adhered to, these two terms can be used to advantage.Gray promoted the "analytic" or "whole word" method of teaching reading supported by attention to context, configuration, structural and graphophonemic cues. He said that children began by memorizing a few words by sight, then developed the sight-word correspondence by using these known words as reference points. Whole-word methods were developed further into "whole language" by Frank Smith and Ken Goodman. Chall cited Gray as the leading expert on reading in the first half of the 20th century.
