With less time to spend with individual students, teachers of large classes may need course materials that augment texts and lectures. The author discusses what criteria such materials must meet and gives examples from a course in statics. (Author/DS)

Discusses how all applications of mathematics have a unifying theme, namely, that of mathematical modeling. Three examples of models in science and technology are briefly described. These are suggested as suitable project work in the classroom, which involve collaborative work between science and mathematics. Advantages and benefits of modeling…

Describes simple methods of making both a reflection and a transmission hologram, as a teaching aid to stimulate students' interest in physics. Lists the various items of equipment necessary for making a hologram. (GA)

Describes a role-playing game that can be used by high school teachers to teach ecology. The procedures of the game are accompanied by pointers for teachers. (SA)

Discusses the educational establishment and relates its position to the need for introducing controversial issues into elementary and secondary classrooms. The need for reform, beginning with science courses in the university, is suggested. (SA)

Describes the phenomenological and microscopic aspects of solid-state diffusion in an electric field and presents a Monte Carlo method which is used to stimulate an atomistic model of diffusion in an electric field. The Nernst-Einstein relation is also discussed. (HM)

Describes an experiment in which acetaminophen is converted into phenacetin, that has been used at Shepherd College in an introductory chemistry course for nurses and in the organic chemistry laboratory. (BT)

A discussion is given of the ways in which thermal conductivity, velocity, and viscosity of sound propagation of gases can be measured by freshmen college students. (Author/SA)

The use of microcomputers in the undergraduate chemistry laboratory is presented. Examples are included which can be implemented in the PET 2001. (SA)

Consistent with the inquiry training goals of the Foundational Approaches in Sceince Teaching program, participants favored laboratory work and field work over individual projects, discussion, and reading assignments; they preferred critical questioning to: recall, principles and explanations, and practical applications. Preference differed for…

Contains articles describing: (1) a writing laboratory at Cedar Crest College (Pennsylvania); (2) 12 biology minicourses used at Elizabethtown Community College (Kentucky); (3) the "Self-Persuasion for Study Improvement Project" at East Tennessee State University; and (4) a vocabulary acquisition program used to help University of North Carolina…

Reports an investigation into the relationship between student attitudes and teacher characteristics. Instructional and student variables are reported as insignificant predictors of changes in attitudes. Significant relationships exist between attitude outcome change and one of the teacher, instruction-student or instruction-teacher variables.…

Describes physics project of the sixth-year of secondary schools in Scotland. The article also discusses: (1) aims of the Scottish certificate of sixth-year studies (CSYS); (2) teacher's role; and (3) method of teaching physics projects. (HM)

Described is a one-week summer chemistry workshop held at Lebanon Valley College, Annville, Pennsylvania, for secondary school students. Experiments and evaluation results of the workshops are provided. (HM)

Describes the details of constructing, and use of, a solar collector. Uses a black liquid to absorb the energy, the thermosyphon effect to drive the liquid through the collector, and a floodlamp as a surrogate sun. (GA)
