The introductory course in college physics has been criticized as fragmented and lacking in a theme or "story" to tie together the disparate chapters. As physicists, we see it as highly organized and hierarchical, developing from the great principles of Newton, Maxwell, etc. But to the student, it's just the chapter on lost hikers, the chapter on…

An activity called "Project Physics, a Classroom Without Walls" was started during the spring of 2003 at the amusement park in Mirabilandia (Italy). Many thousands of students from Italian middle and high schools are today participating in the initiative. Under the guidance of trained tutors, they perform physics experiments on some of the…

As often happens, a lot of physics can come out of a toy. What we found interesting is the observation of the magnetic field produced by different configurations built with GEOMAG[TM]. This toy provides small magnetic bars and steel spheres to play with. Amusing 3-D structures can be built; nevertheless, this possibility is not so obvious. Indeed,…

The overwhelming majority of important papers in physics are written by physicists. But the physician Julius Robert Mayer (1814-1878, see photo) did a valid theoretical calculation of the mechanical equivalent of heat just before Joule reported on his results from his well-known paddle-wheel experiments. Joule is well-known to physics people and…

One of the rewards of walking up the scores of steps winding around the inside of the shaft of a lighthouse is turning inward and examining the glass optical system. This arrangement of prisms, lenses, and reflectors is used to project the light from a relatively small source in a beam that can be seen far at sea.

Most physics instructors are motivated by a genuine interest in their subject area and in using physics to understand real-world phenomena. While many premedical students may share these interests, most are motivated by fulfilling their degree requirements and gaining admittance into medical school. To achieve this latter goal, they need excellent…

This paper describes the construction of a slide-rule computer that allows one to quickly determine magnitudes of several effects that result from the detonation of a nuclear device. Suggestions for exercises are also included that allow high school and college-level physics students to explore scenarios involving these effects. It is hoped that…

The American Association of Physics Teachers (AAPT) mission is to enhance the understanding and appreciation of physics through teaching. Embracing the notion that physics understanding is critical to the wellbeing of society, AAPT is committed to serving its members and the larger community by promoting effectiveness in physics teaching for…

Written by Jim and Jane Nelson, Teaching About Kinematics is the latest AAPT/PTRA resource book. Based on physics education research, the book provides teachers with the resources needed to introduce students to some of the fundamental building blocks of physics. It is a carefully thought-out, step-by-step laboratory-based introduction to the…

The Preparing Future Faculty (PFF) program is a multidisciplinary program involving 43 doctoral degree-granting institutions and more than 250 partner institutions. PFF programs work to transform the way aspiring faculty members are prepared for their careers by focusing on the full range of faculty roles and responsibilities. A PFF program…

Physics First represents an organizational alternative to the traditional high school science sequence. It calls for a re-sequencing of high school courses so that students study physics before chemistry and biology. The purpose of this pamphlet is to provide: (1) Basic information and rationale for the Physics First curriculum; (2) Strategies for…

The American Association of Physics Teachers (AAPT) mission is to enhance the understanding and appreciation of physics through teaching. Aspiring to advance the greater good through physics, AAPT strives to be the leading voice, primary resource, advocate of choice, and driving force in physics education, serving professionals who teach physics…

The Task Force on Graduate Education in Physics (TFGE), an ad hoc committee convened jointly by the American Association of Physics Teachers (AAPT) and the American Physical Society (APS), has studied the current status of graduate education in physics Ph.D. programs, and has made recommendations based on what was found. The findings indicate that…

In July of 2005, the American Association of Physics Teachers/Physics Teacher Resource Agents (AAPT/PTRA) Rural Project gathered 73 PTRAs at the University of Utah in Salt Lake City for the annual AAPT/PTRA Leadership Institute. The major goal for the summer institute is to provide the PTRAs with the knowledge and skills needed to effectively lead…

This report summarizes the activities and findings of Horizon Research, Inc. (HRI) in its external evaluation of the American Association of Physic Teachers (APPT's) Rural Physics Teacher Resource Agents (PTRA) project. The report details HRI's work and findings since June 2004. The report is divided into five main sections. The first provides an…
