This textbook for ESL contains ten lessons, plus a preface lesson to introduce the format. It is designed for use by Spanish-speaking high school students. All directions are given in both languages. Each lesson contains a statement of rationale and learning objectives, a pre-test, a list of sources of information to aid in learning the lesson (e.g., textbooks, teachers, students aides), numerous workbook and drill activities in grammar and the structure, a final evaluation test, and additional activities. The text is semi self-instructional and self-paced; teacher guidance and reinforcement are necessary. (DD)
