Organized around a linguistically sound, programmed approach to teaching spelling, Dr. Fergus's text is well known for its clear writing and lucid discussion of the relationships of sound, word origin, and rules of spelling. With separate chapter coverage for each of 16 problem areas and with a built-in testing program, SPELLING IMPROVEMENT, Fifth Edition, helps students at many different levels not only spell the words in the text, but also become independent spellers once they have completed the course and are on their own.
