Presents a two part study of the effect of classroom observation on teacher effectiveness. (SL)

Reviews the subject of the electronic structures of metals which produce magnetism. (SL)

Describes an apparatus for quickly demonstrating the quantum effect of freezing the rotational energy of molecular hydrogen. (SL)

A factorial design which intersected process skill instruction with field experience was utilized. Significantly higher physics achievement scores and process skill competency were observed for the field-experience, process-supplemented physics course. (CP)

Reports the findings of a study involving teacher assessment of practical work in secondary level physics courses taught in Northern Ireland. Assessment is made by a single standardized examination. (SL)

Describes a procedure for integrating computer graded homework into physics courses. (SL)

This paper describes a Personalized System of Instruction (PSI) general physics course taught within the constraints of a small community college. The PSI format is described and student opinions of it are presented. (Author/CP)

An experiment is described in which students in an introductory laboratory can determine all of the relevant energy flows of an ordinary household refrigerator. (Author/CP)

Describes apparatus utilized to demonstrate physics principle. Equipment described includes a low pressure chamber, a 360 degree loop ramp, a tilted table demonstrating motion principles, and a method for casting a three dimensional display of magnetic lines of force. (SL)

HELP (P), the Higher Education Learning Project (Physics) is a collaborative venture among teachers of physics in several British universities involving skill development, stimulation of individualized study, and teaching techniques. (LBH)

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)
