Describes an approach which emphasizes the physical aspects of periodic phenomena, and is explicit about whether the time or space domain is being treated. (Author/GS)

Illustrates a safe and easy way of igniting a hydrogen-oxygen mixture and lists the equipment used. (BR)

Describes how you can lead students to erroneous inferences and conclusions by using demonstrations which point out to students the importance of carefully distinguishing between observations and inferences. (BR)

Describes a chemistry curriculum for college freshmen that uses laboratory study of the chemical composition of meals eaten by students as the central activity from which theoretical and practical learning are derived. Presents a meal analysis flow diagram and a table of concepts included in the program. (GS)

Describes the inexpensive construction of an uptake volume potometer uptake and loss potometer, and experiments on plants that can be conducted with the equipment. (BR)

Describes a science program for the mentally retarded institutionalized adult. Raises questions concerning the practicality of science exposure in lieu of or in addition to vocational training. (BR)

The demonstration of a simple viscosity experiment for high school classes was conducted and assessed. The purpose of the demonstration was to elicit the interest of high school juniors and seniors in the field of chemical engineering. The demonstration consisted of a discussion on both engineering and the concept of viscosity as well as a…

This is the final report of a series of 19 experiments designed to study impasses in the learning of skills with a strong perceptual component. Several series of experiments were designed with the purpose of producing experimentally manipulable impasses or plateaus in the course of learning. Over 200 subjects (humans and animals) in learning…

A pair of experiments, appropriate for the lower division fourth semester calculus or differential equations course, are presented. The second order differential equation representing the equation of motion of a simple pendulum is derived. The period of oscillation for a particular pendulum can be predicted from the solution to this equation. As a…

This paper describes the way in which the University of Lowell Instructional Network is being used to provide local schools with access to the university's facilities and faculty. The STAR (Science Teachers Accessing Resources) program is described in detail from its inception, through the planning stages, culminating in two-way television…

Experimental studies conducted since 1980 were reviewed. Each of the 34 studies concerning problem solving is briefly summarized, followed by comments, criticisms, and/or concerns. A summary indicates that experimental research of the 1980s seems to focus on: (1) children's processes, understanding, functioning, difficulties, and representations;…

Two interventions were studied in this project: a drama program presented by three visiting drama consultants in five classes and a daily story-reading period presented by the teacher in three classes and by the co-investigator in another three classes. The interventions lasted for 12 weeks. Subjects were 325 first grade pupils from 21 classrooms…
