Connected Learning Paths for Core Topics At the heart of this revision is the connection between the book and its media. The media resources were developed alongside the text in order to create a connected learning path from the book throughout the media package. Through extensive reviewing we identified the genetics topics and skills that students find most difficult. We then designed our media to include the types of resources that instructors felt would best help students understand these topics, study, and practice problem solving—a key skill that is crucial to understanding genetics. To give you an idea of how our media resources connect with the book, here are a few examples of the learning paths we visualized for two of the topics that are consistently noted by instructors as difficult for their students.

New Problem-Solving Videos offer students valuable help by reviewing basic problem-solving strategies. The problem-solving videos demonstrate an instructor working through problems that students find difficult in a step-by-step manner.

New Online Branched Tutorials identify where students have difficulty and route them through the steps of the problem according to the answers they enter. Hints allow students to receive feedback along the way, as if they were working the problem with an instructor.

New Online Worked Problems allow students to step through a worked problem online in the same format that they’ve seen in the book. Hints provide feedback as they work through the problem.

Updated and New Animations/Simulations help students understand key processes in genetics by outlining them in a step-by-step manner. The animations and simulations now include assessment questions at the end to help students evaluate whether they understood the concept or technique they viewed.

Comprehensively Revised Assessment All media resources have undergone extensive rewriting, reviewing, and accuracy checking.

Nature Genetics Articles with Assessment engage students with primary research and encourage critical thinking. Specifically selected for both alignment with text coverage and exploration of identified difficult topics, the Nature Genetics articles include assessment questions that can be automatically graded. Some of the open-ended (non-multiple-choice) questions are also suitable for use in flipped classrooms and active learning discussions either in class or online.

Newly Updated Clicker Questions allow instructors to integrate active learning into the classroom and to assess students’ understanding of key concepts during lectures. Available in Microsoft Word and PowerPoint, numerous questions are based on the Concept Check questions featured in the textbook.

New Lecture PPTs have been developed to minimize preparation time for new users of the book. These files offer suggested lectures, including key illustrations and summaries that instructors can adapt to their teaching styles.

Textbook Images and Tables are offered as high-resolution JPEG files. Each image has been fully optimized to increase type sizes and adjust color saturation. These images have been tested in a large lecture hall to ensure maximum clarity and visibility.

The Solutions and Problem-Solving Manual (written by Jung H. Choi, Georgia Institute of Technology, and Mark E. McCallum, Pfeiffer University) contains complete answers and worked-out solutions to all questions and problems in the textbook. The manual has been reviewed for accuracy and has been found to be an indispensable tool for success by students. The Solutions Manual is also available in print (ISBN: 1-4641-5092-3).

Reformatted Worked Problems walk students through difficult quantitative concepts in an easy to follow manner, presenting a Solution Strategy and Solution Steps for each worked problem. Hint balloons remind students of key points to keep in mind or refer them back to a specific part of the text to review.

NEW Figure-Based End-of-Chapter Problems bring a visual aspect to problem solving, engaging students closely with figures in each chapter and helping them assess their understanding of key concepts and processes.

NEW Introductory Stories Each chapter begins with a brief introductory story that illustrates the relevance of a genetic concept that students will learn in the chapter. These stories—a favorite feature of past editions—give students a glimpse of what’s going on in the field of genetics today and help to draw them into the chapter. Among the new introductory story topics are “The Odd Genetics of Left-Handed Snails” and “Building a Better Banana.” End-of-chapter problems specifically address concepts discussed in most introductory stories, both old and new.
