A study found first-year physics students at the University of Namibia (UNAM), considered to be a select group of students, to be as prepared for laboratory work as Australian tenth-graders. Comparison with students of Potchefstroom University (South Africa) found UNAM students deficient in both cognitive and affective aspects of laboratory work.…

Presents several types of functions which fit a given set of data and create opportunities for classroom discussion comparing different kinds of functions and identifying some of the potential hazards associated with extrapolation from best-fit functions. (DDR)

Presented is a unified science and technology instructional model that emphasizes multidisciplinary learning through discovery and hands-on activities. Two courses, developed from this model, are described in terms of curriculum, teaching methods, scheduling, credit, limitations, enrollment, and promotion. (KR)

This study reports a new analysis of data on children's ideas about direct current (DC) electrical circuits. The analysis is theoretically informed by Piagetian stage theory of genetic epistemology. The limits of the genetic epistemology are discussed. (KR)

Within 40 departments, 10 each of physics, sociology, electrical engineering, and education, faculty commitment to the institution was assessed for each career stage and level of research productivity, examining the relative power of rewards and support variables. A meaningful but differential role for rewards is found among the disciplines.…

Described are the apparatus and procedures needed for a demonstration of the measurement of the electrical resistance of metals as a function of temperature using a microcomputer interface. Discussed are materials, apparatus construction, and experimental results. (CW)

Described are the apparatus and procedures needed for a demonstration of a determination of the polarity of charges carried by individual ground flashes of lightning. Discussed are materials, apparatus construction, and experimental results. (CW)

Described are the apparatus and procedures needed for this correction technique using a microcomputer interface. Discussed are materials, apparatus construction, and experimental results. (CW)

Interactive science and technology centers are described that emphasize "hands-on" science. Examined are the outreach programs offered by many centers which include traveling exhibitions and published resource materials. Examples of follow-up activities to a center visit are included. (KR)

Examined is the contribution that hands-on, interactive centers can make to science education. The characteristics of informal and formal learning are compared and discussed. (KR)

Advocated is the use of interactive centers to supplement existing classroom laboratory experiences. Activities found in the center and modified classroom versions are described. The problems that arise when primary students meet sophisticated exhibits is discussed. (KR)

Discusses chaotic behavior (movement) in a nonlinear system using LOGO programs. Presents several examples with program listings. (MVL)

Described is a program for two-week, tuition-free courses offered twice a year dealing radiation and radioactivity. Laboratory exercises, tours, schedules, enrollment and accreditation, and staffing are discussed. (CW)

Notes the computer has progressed from being a fast calculating machine to becoming an important tool for the whole academic spectrum. Discusses the development of new courses being offered to develop skills and knowledge in computational physics. (Author/MVL)

Considers the development of a computer program for interactive, screen-oriented problem solving. Provides theoretical background and program development to determine internal energy, heat capacity, and entropy. Lists the program written in BASIC for Apple II computers. (MVL)
