For the 11th edition of BIOLOGY: UNITY AND DIVERSITY OF LIFE, Cecie Starr and Ralph Taggart made it their goal to "solve" some of the toughest Introductory Biology course challenges. We introduce a new issues-oriented approach with engages students in current, motivating biological topics; a built-in cross-referencing system for key topics; and, most importantly, time-saving media resources for instructors. Show students how biology matters ? Opening each chapter with engaging essays on hot issues and related online voting, the text highlights the connections between biology and real-life. Online exercises promote critical thinking about issues students will face as consumers, parents and citizens. Link concepts from chapter to chapter - Students often have a difficult time with this, so the authors created a "linking" tool. A list at the start of each chapter reminds students of related topics that were explained earlier. Within chapters, a key icon identifies cross-references to relevant sections in earlier chapters. As students work through the text, they see how topics build upon one another. Monitoring students' progress with ease - BiologyNow? offers diagnostic quizzes with automatically graded results that flow directly into your instructor gradebook (iLrn, WebCT or BlackBoard). And, to assess students' progress instantly with in-class quizzes and polls, you can use JoinIn? on TurningPoint® content and software. Easier lecture prep - The new PowerLecture tool integrates all chapter assets - art, photos, animations, videos, links to InfoTrac articles, web links and everything else you need into each chapter's lecture slides. This "buffet" of media resources?arranged by chapter section is at your fingertips. Just cut and paste what you want into your lecture file.
