AP Biology is structured around four Big Ideas (Evolution, Energy Processes, Information, and Interactions) described in the Curriculum Framework, which encompass the core scientific principles, theories, and processes governing living organisms and biological systems. At least one of the Big Ideas will be incorporated in every lesson throughout the course. [CR2] Because evolution is the foundation upon which the entire course is based, it will be referenced throughout the entire course, and science as a process will be threaded throughout both the investigations and the class activities outside of the investigations.

Students begin each lesson with a list of learning objectives and essential questions to guide them throughout the main points of each lesson and to frame students’ class notes. Students are encouraged to add to these notes, listing all questions that arise. Lessons may be based on multimedia resources from various sources (textbook, CDs, Internet, etc.) to help the students make critical connections between what they are learning and their everyday lives. Quizzes are interspersed throughout the module. These assessments provide information on how teachers may need to adjust instruction to improve student learning.

Students will have regular discussions with their instructor to apply biological, scientific knowledge and critical-thinking skills to major issues of social concern. During these discussions, students must explain the science and science processes being applied. In addition, students will need to be prepared to demonstrate their content mastery through a variety of assessment formats, some of which will be informed by readings from recent scientific journals. Students will also be given the opportunity to see that biology is in their everyday lives and is not just a chapter in a textbook.
