Mariëlle Hoefnagels' passion as a classroom instructor is evident in Biology: Concepts and Investigations, an introductory biology textbook written to explain the general concepts of biology at a level of detail that allows students to understand concepts ratherthan memorize details. New digital resources, upgraded PowerPoint presentations, tutorial animations based on textbook art, upgraded Connect question banks, and adaptive technologies like SmartBook with Learning Resources capitalize on the power of technology to enhance student understanding. Key goals of the book are to:

-help the student connect the concepts in thebook to their everyday lives

-show connections between ideas within thechapter and to material they have already studied

-teach introductory students how to be moreactive learners
