What choices do language teachers have in making materials and procedures more effective in the classroom? What role does mental imagery play in these choices? In this original book, Earl Stevick shows how an understanding of imagery can aid teachers in identifying and evaluating man), of the alternatives available for their day-to-day work in the classroom. Using samples from current language textbooks at all levels, he shows how combinations from thirty-three different options can generate both the needed techniques and their variants. This book can thus be seen as a convincing development of the theme in his earlier volume, Teaching and Learning Languages, that language teaching should be a matter of informed choice.
