Synopses & Reviews
'Designed for first-year developmental math students who need support in beginning algebra, Elementary Algebra, 4/e, retains the hallmark features for which the Larson team is known: abundant, high-quality applications; the use of real data; the integration of visualization (figures and graphs) throughout; and extensive opportunities for self-assessment (mid-chapter quizzes, review exercises, tests, and cumulative tests). In developing supportive new features for the Fourth Edition, the authors\' goal is for students to come away from the class with a firm understanding of algebra and how it functions as a modern modeling language.'
About the Author
Ron Larson received his Ph.D. in mathematics from the University of Colorado and has been a professor of mathematics at The Pennsylvania State University since 1970. He has pioneered the use of multimedia to enhance the learning of mathematics, having authored over 30 software titles since 1990. Dr. Larson has also conducted numerous seminars and in-service workshops for math teachers around the country about using computer technology as a teaching tool and motivational aid. His INTERACTIVE CALCULUS (a complete text on CD-ROM) received the 1996 Texty Award for the most innovative mathematics instructional material at the college level, and was the first mainstream college textbook to be offered on the Internet.The Pennsylvania State University, The Behrend College Bio: Robert P.
