The author discusses the criteria to be considered in evaluating textbooks for classes of English for Speakers of Other Languages (ESOL). They are: (1) the age and proficiency level of the students; (2) the amount of time allotted for ESOL classes; (3) the treatment of the four language skills and all subject areas; (4) gradation and presentation of grammar, vocabulary and reading, pronunciation, and visual aids; and (5) the amount of practice drills provided. He warns that "the textbook that deals with form, syntax, and function without treating meaning fails both the student and the teacher." He concludes that any textbook is only as good as the teacher using it. (DO)
