THIRD EDITION

In our years of teaching the fundamental concepts of chemistry to students with widely divergent backgrounds, levels of preparation, career goals, and motivation, the most frequently asked question by those students has been, Do you have something that I can study on my own? followed immediately by, I need some other review material or This is the first time I have encountered this stuff, so I need to start from scratch or It has been 3years since my high school chemistry course. I need something to refresh my memory.

This book has been written to meet such needs. It can stand alone as a first look at chemistry or may be used as a supplement to any of the many excellent textbooks or methods of instruction currently in use. The material presumes no previous exposure to chemistry and requires only simple algebra.

There are no secrets. Each chapter includes an introductory statement, a list of objectives, and the main teaching section, which consists of frames of tutorial material with constant practice exercises. Each chapter closes with a self-test. You can use this self-test to assess whether you have mastered the chapter well enough to continue and to identify weaknesses that require additional study. Finally, some chapters include an end-of-chapter or transitional story connecting the material to a relevant topic in chemistry.

The topics presented are usually covered early in a general introductory course. The third edition also contains a new chapter on organic chemistry consistent with the material found in general chemistry textbooks. We have minimized heavy theoretical discussions, while emphasizing descriptive and practical concepts. There is enough theoretical explanation to provide a basis for understanding the material but not so much that you will get bogged down trying to work through the book.

Chemistry: A Self Teaching Guide is unlike the ordinary textbook. It is designed to be completely self-instructional, requiring no chemistry background. The previous editions have been thoroughly tested as a successful means for self-instruction in chemistry for thousands of students. The book can also be used as a supplementary text for any general chemistry course. Each chapter is divided into objectives, an interactive tutorial study section, a self-test, and test answers.

• Objectives. By examining the chapter objectives, you can determine what information is contained in each chapter. If you already know the material, take the self-test at the end of the chapter. Review those questions you missed by checking the frame references given with the answer to each question.
• Tutorial study frames. The body of each chapter is divided into numbered frames. Each frame contains new information, a problem, or an example of a concept with one or more questions for you to answer. Answers for the questions in each frame are given immediately below the questions. Years of educational research have proven this method of immediate reinforcement with the correct answer to be the most effective and efficient means of learning for self-instruction. While having the answer just below each question assures immediate feedback to reinforce learning, it also requires discipline on your part to think about the answer before viewing. We suggest using a bookmark such as an index card as you go down each page, covering the answer below while you critically think about the answer or solve a problem. Each question and answer frame is crafted as a small step, like each step on a staircase, designed to lead to a fuller understanding of a concept in chemistry.
• Self-test. The self-test at the end of each chapter will help you to determine whether you have mastered the chapter material. After completing the chapter, take the test. Refer back to the chapter only if you need formulas or tables to answer specific questions. Compare your answers with those given immediately following the test. If your answers do not agree with the printed ones, review the appropriate frames cited after each answer.
