Physics by Inquiry is a set of laboratory-based modules that provide a step-by-step introduction to physics and the physical sciences. Through in-depth study of simple physical systems and their interactions, students gain direct experience with the process of science. Starting from their own observations, students develop basic physical concepts, use and interpret different forms of scientific representations, and construct explanatory models with predictive capability. All the modules have been explicitly designed to develop scientific reasoning skills and to provide practice in relating scientific concepts, representations, and models to real world phenomena.
Physics by Inquiry is not meant to be passively read. The modules do not provide all the information and reasoning included in a conventional text. There are gaps that must be bridged by the student. The process of science cannot be learned by reading, listening, memorizing, or problem-solving. Effective learning requires active mental engagement.
Physics by Inquiry contains narrative, experiments and exercises, and supplementary problems. As the course progresses, student notebooks become an important resource.
Narrative: The narrative is double-spaced. It includes statements of fact, definitions, and examples of the kind of reasoning that is expected of students.
Experiments and exercises: Experiments and exercises are inset from the narrative. They should be done as they are encountered.
Supplementary problems: A collection of problems at the end of each module provides additional practice in applying physical concepts and scientific reasoning skills.
Student notebooks: Students maintain notebooks in which they record observations, do exercises and problems, and reflect on how their understanding is evolving. In this way, they create an indispensable reference that complements the text and serves as an individualized study guide.
Note to the instructor
Physics by Inquiry consists of two volumes. The first two are subtitled: An introduction to physics and the physical sciences. Volume I develops fundamental concepts and basic reasoning skills essential for the physical sciences. The material included in Volume II provides a foundation for the study of introductory physics. With the exception of Electromagnets and Astronomy by Sight, Volumes I and II can be used independently.
Physics by Inquiry has been designed for courses in which the primary emphasis is on discovering rather than on memorizing and in which teaching is by questioning rather than by telling. Such a course allows time for open-ended investigations, dialogues between the instructor and individual students, and small group discussions. A major goal is to help students think of physics not as an established body of knowledge, but rather as an active process of inquiry in which they can participate.
Physics by Inquiry is particularly appropriate for preparing preservice and inservice K–12 teachers to teach science as a process of inquiry. The modules can also be used to help underprepared students succeed in the mainstream science courses that are the gateway to majors in science, mathematics, engineering, and technology. For these student populations, as well as for those in the liberal arts, the curriculum helps establish a sound foundation for the building of scientific literacy.
Physics by Inquiry has an accompanying Instructor’s Guide for college and university faculty. It has several purposes: to suggest how the materials can be most effectively used with different student populations, to help the instructor anticipate student difficulties, to provide information about the equipment, to describe the demonstrations referred to in the text, and to convey the purpose of unusual exercises and experiments.
Development of Physics by Inquiry
Physics by Inquiry is the product of an intensive, collaborative effort by the Physics Education Group in the Physics Department at the University of Washington. Directed by Lillian C. McDermott, the group includes faculty, research associates, and graduate students. Members of the group conduct in-depth investigations of student understanding through which they identify and analyze specific difficulties that students encounter in studying physics. This research has provided the foundation for the design of the instructional strategies that are incorporated in Physics by Inquiry.
Physics by Inquiry has been developed through an iterative, interactive process of research, curriculum development, and instruction. The participation of the Physics Education Group in the instructional program of the Physics Department has made it possible to design, test, and modify the curriculum in a continuous cycle on the basis of regular feedback from the classroom. In addition to monitoring the effectiveness with students at the University of Washington, the Physics Education Group has been able to draw on the experience of instructors at other institutions who have pilot-tested earlier editions of the modules. The extensive testing and subsequent revision that have been an integral part of the development process have helped ensure that Physics by Inquiry is well-matched to the students for whom it is intended.
Physics by Inquiry has evolved into its present form over a long period of time, during which the co-authors have shared intellectual leadership and editorial responsibility. In the early versions of the curriculum, Mark L. Rosenquist helped establish the instructional approach that underlies all of the modules. In all the later versions and in the additional modules that appear in this first published edition of Physics by Inquiry, Peter S. Shaffer has played a pivotal role.

The development of Physics by Inquiry has drawn on several published instructional materials. One important source has been The Various Language by Arnold Arons. Some of the precollege curricula developed with NSF support, such as ESS, SCIS, IPS, PSSC Physics, and Project Physics, have also been excellent resources.
Support by the National Science Foundation and the Physics Department has enabled the Physics Education Group to conduct the coordinated program of research, curriculum development, and instruction that has produced Physics by Inquiry. The encouragement of Clifford W. Mills at John Wiley & Sons, Inc., has also been deeply appreciated.
