เนื้อหาย่อ : Overview Purpose INTERMEDIATE ALGEBRA: AN APPLIED APPROACH is a newly developed text which covers all the topics considered essential in a second-year algebra course, empha- sizing applicatio's of algebra throughout. The text has been specifically developed to meet not only the needs of the traditional college student, but also the needs of the mature student whose mathematical proficiency may have declined during years away from formal schooling. Contents INTERMEDIATE ALGEBRA: AN APPLIED APPROACH is the third in a series of three texts by the authors: BASIC COLLEGE MATHEMATICS: AN APPLIED APPROACH INTRODUCTORY ALGEBRA: AN APPLIED APPROACH INTER MEDIATE ALGEBRA: AN APPLIED APPROACH The frst book, BASIC COLLEGE MATHEMATICS: AN APPLIED APPROACH, provides a comprehensive coverage of computational skills and their applications. IN- TRODUCTORY ALGEBRA: AN APPLIED APPROACH contains a complete devel- opment of the basic skills and applications typically found in a first-year algebra course. INTERMEDIATE ALGEBRA: AN APPLIED APPROACH covers the essentials of second-year algebra as well as certain more advanced pre-calculus topics. Since the three texts share several important pedagogical and organizational features, they may be used sequentially to reap the benefits of a smoothly-integrated series of learning materials. However, because the three texts have been written so that the content of each is inde- pendent of the other two, any one book in the series may be used independently of the other two. rganization INTERMEDIATE ALGEBRA: AN APPLIED APPROACH is organized into 12 units. Each unit is divided into a varying number of sections, and each section contains several related objectives. Any one objective contains the exposition of a single skill or applica- tion. The exercise sets found at the end of each section are grouped by objective to establish a simple matching between exposition and related practice problems. The two Review/Tests found at the end of each unit are also organized by objective, in order to define a clear correspondence between exposition and related testing. Features INTERMEDIATE ALGEBRA: AN APPLIED APPROACH is built around the three proven and effective teaching strategies which are characteristic of the entire series. First, an applied approach generates an awareness of the value of algebra as a practical tool. Second, an interactive approach encourages the student to practice each skill while it is being presented, thus avoiding needless confusion later when working practice assign- ments. Third, an objective-specific approach helps the student or the Instructor manage instruction, improving both the efficiency and the effectiveness of the instruction. These three strategies are described pictorially on the next three pages.
