The social, economic, and educational background of Jamaican students is presented to show the difficulties of trying to teach physics. (DS)

The objectives and methods of a free undergraduate laboratory are set forth. The main features are a close connection between the students and the research groups, a large amount of student freedom and responsibility, and no grading of the students. (Author/TS)

A game simulating an Einstein model of a crystal producing a Boltzmann distribution. Computer-made films present the results with large distributions showing heat flow and some applications to entropy. (TS)

Presents one school's philosophy and processes in the adaption of a unified science program. Describes the programs, philosophy, sequencing, organization, and advantages. (DS)

Reports a student-computer dialog for beginning or intermediate physics classes. This dialog enables the student to take some initiative in showing that energy conservation in one dimension is a consequence of the laws of motion. (DS)

Presents the theoretical explanation of the observation that when a pen that is stuck in a hard rubber ball and dropped, the pen may bounce to several times the dropped height. Includes the procedure and models created to explain the observations. (DS)

Presents information about the nucleus gained by studies of electron scattering. Discusses what can be implied about the shape of the charge distribution, the nucleus positions, the vibrational modes of the nucleus, the momentum of the nucleus, and the granularity and core structures of the nucleus.
