This issue presents a collection of articles which critique the educational reforms in science and mathematics initiated in 1983. The articles devote special attention to physics, biology, mathematics, geography, and the instructional problems Soviet teachers encountered in presenting the new curricula. (JDH)

Winners of a contest run by the EDUCOM Software Initiative, a project to promote development and dissemination of instructional software for higher education, are identified. Criteria included the appropriateness of the software for use in higher education, its reliability, appeal and ease of use, etc. (MLW)

Describes the new class of oxide superconductors, the importance of these materials, and the concepts that led to its discovery. Summarizes the discovery itself and its early confirmation. Discusses the observation of a superconductive glass state in percolative samples. (TW)

Introduces optical experiments and observations for an airplane passenger including scratches on a window, scattering of light, and reflection images. Provides several diagrams. (YP)

Introduces a 3-dimensional mechanical lattice with adjustable telescoping mechanisms. Discusses the crystalline state, the 14 Bravais lattices, operational principles of the mechanical lattice, construction methods, and demonstrations in classroom. Provides lattice diagrams, schemes of the lattice, and various pictures of the lattice. (YP)

Reviews the usage of Genecon, a hand-operated generator, in science laboratory experiments, such as the relationship between motor and generator effects, the system's efficiency, Joule heating, and conversion of mechanical energy into electrical potential energy. Provides the address for purchasing the Genecon and accessories. (YP)

Presents two views about lenses and optics in attempt to clarify a story written by Carolyn Hermann, "Through the Magnifying Glass." Cites two references for additional reading on students' optics difficulties. (RT)

Studies time intervals in a list of critical ideas in physics. Infers that the rate of growth of ideas has been proportional to the totality of known ideas multiplied by the totality of people in the world. Indicates that the rate of discovery in physics has been decreasing. (CW)

The University of Alabama Summer Physics Teachers Institute is a cooperative program of the university's College of Education and College of Arts and Sciences for noncertified physics teachers. The program features observation of master teachers, seminars with visiting scholars, follow-up evaluation by participants, state funding, and recognition…

Discusses the uses of thermistors in teaching electronics and semiconductors. Describes how to experimentally measure and graph the characteristics of a thermistor. Suggests one possible approach to understand the shapes of the characteristics. (CW)

Describes: (1) the structure of a data transmission source, carrier, and receiver; (2) a quantitative measure for the amount of data, followed by some quantitative examples of data transmission processes; (3) the concept of data current; (4) data containers; and (5) how this information can be used to structure physics courses. (JN)

Describes a simple three-dimensional model of Halley's Comet orbit (which is much more informative than a two-dimensional drawing) to illustrate spatial relationships and visualize how the comet moves relative to the earth. Instructions for model assembly are given along with a template which can be photocopied and glued to cardboard. (JN)

A number of alternative frameworks used by 84 students (ages 12-16) in interpreting phenomena concerned with fluid pressure were identified during interviews with these students. Methodology employed, tasks used to obtain data, an analysis of the results, and implications for physics teaching are included. (JN)

Compared performance in A-level science examinations of students who took an integrated science course (SCISP) with students who studied the separate subjects of physics, chemistry, and biology to 0-level standard. Results show no significant differences between the performance of the two groups. (JN)

Discusses the velocity of an orbiting satellite. Knowledge of the kinematics of falling objects is the only prerequisite for understanding the concepts considered. (DH)
