Written in the spirit of the reform movement that is reinvigorating the introductory majors course, Principles of Life cuts through the thicket of excessive detail and factual minutiae to focus on what matters most in the study of biology today. Students explore the most essential biological ideas and information in the context of the field’s defining experiments, and are actively engaged in analyzing research data. The result is a textbook that is hundreds of pages shorter (and significantly less expensive) than the current majors introductory books.

With its first edition, Principles of Life provided a textbook well aligned with the recommendations proposed in BIO 2010: Transforming Undergraduate Education for Future Research Biologists and Vision and Change in Undergraduate Biology Education. Now Principles of Life returns in a thoroughly updated new edition that exemplifies the reform that is remaking the modern biology classroom.

Biology: How Life Works was written in response to recent and exciting changes in biology, education, and technology with the goal of helping students to think like biologists. The text, visual program, and assessments were developed together to provide students with the best resources to gain an understanding of modern biology. Content is selected carefully, is integrated to illustrate the connections between concepts, and follows six themes that are crucial to biology: the scientific method, chemical and physical principles, cells, evolution, ecological systems, and human impact. The second edition continues this approach, but includes expanded coverage of ecology, new in-class activities to assist instructors in active teaching, new pedagogical support for visual synthesis maps, and expanded and improved assessment.

Students and instructors are living through a pandemic that has changed how and what they teach, and how and where they learn. The COVID-19 Update of Principles of Economics, Third Edition, provides the information that students need to make sense of the impacts COVID-19 has had on the economy. The Update Edition has been completely revised to include new examples, new data, new policies, and more. All of NortonÕs digital resources fully integrate with most learning management systems, providing the flexibility instructors need in this changed world.
