What We Are About: A Message from the Development Committee

The AP Physics Development Committee recognizes that curriculum, course content, and assessment of scholastic achievement play complementary roles in shaping education at all levels. The committee believes that assessment should support and encourage the following broad instructional goals:

1. Physics knowledge — Basic knowledge of the discipline of physics, including phenomenology, theories and techniques, concepts and general principles

2. Problem solving — Ability to ask physical questions and to obtain solutions to physical questions by use of qualitative and quantitative reasoning and by experimental investigation

3. Student attributes — Fostering of important student attributes, including appreciation of the physical world and the discipline of physics, curiosity, creativity, and reasoned skepticism

4. Connections — Understanding connections of physics to other disciplines and to societal issues

The first three of these goals are appropriate for the AP and introductory-level college physics courses that should, in addition, provide a background for the attainment of the fourth goal.

The AP Physics Exams have always emphasized achievement of the first two goals. Over the years, the definitions of basic knowledge of the discipline and problem solving have evolved. The AP Physics courses have reflected changes in college courses, consistent with our primary charge. We have increased our emphasis on physical intuition, experimental investigation, and creativity. We include more openended questions in order to assess students’ ability to explain their understanding of physical concepts. We structure questions that stress the use of mathematics to illuminate the physical situation rather than to show manipulative abilities.

The committee is dedicated to developing exams that can be graded fairly and consistently and that are free of ethnic, gender, economic, or other bias. We operate under practical constraints of testing methods, allotted time and large numbers of students at widely spread geographical locations. In spite of these constraints, the committee strives to design exams that promote excellent and appropriate instruction in physics.
