Preface

To the Instructor I offer the following suggestions based on countless correspondences with instructors who teach our subject. I have learned that there are many viable approaches for achieving student success depending on course objectives and classroom facilities. Since I teach in a media classroom, I incorporate PowerPoint® and video presentations, Internet assignments, collaborative learning, chemical demonstrations, as well as traditional techniques. It is my experience that lecture materials have a relatively short lifespan and I must renew each presentation or students sense a lack of freshness. To accompany this Eighth Edition of Introductory Chemistry: Concepts and Critical Thinking there is a plethora of technology including an Instructor Resource Center with pre-built PowerPoint® presentations, animations, interactive activities, Instructor’s Manual lecture outlines, and a Test Bank in Word® format. In terms of a guiding principle, I obtain the best results when I organize an entire course so as to include one or more interesting asides in each lecture. This adds an extra dimension to every presentation; for example, I may provide a media supplement, an Internet assignment, or a chemical demonstration, depending on the topic. A second guiding principle is that the lecture topic should be supported by a corresponding laboratory experiment. For example, when discussing the Bohr atom, I demonstrate emission line spectra in lecture, while students perform the experiment Atomic Fingerprints found in the Pearson Laboratory Manual.

Testing For introductory chemistry classes, I have found that frequent testing improves test scores, achieves higher attendance, and more students successfully complete the course. The Test Bank for the Eighth Edition contains over 3000 questions, covering key terms, each learning objective, and general questions that are cumulative in nature. This unparalleled resource has been class-tested on thousands of students and each question and answer have undergone detailed item analysis. Print and Media Resources Introductory Chemistry: Concepts and Critical Thinking, 8e, has numerous ancillaries and the following are available to the instructor upon adoption of the textbook: • Instructor Resource Center • Instructor Manual and Test Bank • MasteringChemistry® Acknowledgments I would like to thank the many reviewers, colleagues, and adoptees who have used the textbook and ancillary materials in previous editions and offered valuable comments that provide accuracy and balanced coverage. I have acknowledged these individuals in the preface of the text, and I welcome your comments for this latest edition and invite you to contact me directly.
