The purpose of this study is to describe types and structural properties of instructional activities used by physics and chemistry preservice teachers (N=4) during their teaching of pupils 14 to 16 years old. The study involved the observation and tape recording of 64 classes with all tapes transcribed verbatim. Analysis involved the decomposition…

Recent reforms in science education call for curricula designed to support students' construction of knowledge through inquiry. Teachers need to learn new methods and content to enact reform-based curriculum, and educative materials designed to address teacher as well as student learning are one vehicle for this type of reform. This paper…

This report follows up the employment status of 1997 physics and astronomy degree recipients. The report notes that: (1) only 2 percent of 1997 doctoral degree recipients were unemployed in the winter of 1998; this is down from a recent high of 6 percent for the class of 1993; (2) half of new physics Ph.D.s in the class of 1997 accepted permanent…

This report provides data on students earning physics and astronomy bachelor's degrees for the 1997-98 academic year. The report notes that: (1) after many years of steady decline, the number of undergraduates earning physics bachelor's degrees has stabilized, with 3,821 degrees awarded in l997-98; (2) declines in undergraduate degrees persist at…

The progressive agenda of science education reform, particularly the goal of promoting student inquiry, places substantial intellectual demands on teachers. If this reform is to succeed, the education community must do more to appreciate and address its demands. This paper presents three examples of high school physics teachers' conversations…

Describes student projects on applications of solar energy optics to home design. Project criterion (requiring sketches and detailed calculations of time rate of energy flow/production) is that half the heat for the heating season be taken from the solar resource; calculations must be based on meteorological data for a specific location. (JM)

Assessed Nussbaum's developmental model (SE 024 045) using a new sample given no special instructions in spherical earth/gravity concepts. Also identified distribution of notions among students (N=159 in grades three to eight), compared distribution of notions at each age level with those in other studies, and explored role of individual…

Describes a two-semester laboratory program designed to motivate students. The program consists of computer-oriented modules and discovery approach laboratory exercises. Students complete similar computer/laboratory material during the first semester but elect one of three tracks during the second semester (computer, every-day life, and…

Discusses development of a multi-media learning center at Illinois Institute of Technology, focusing on strategy used to obtain National Science Foundation funding and the center's operation. The latter includes hardware, location and physical layout, courseware, public relations, staffing, student use, and future endeavors. Also provides an…

Microcomputer-based instrumentation packages enable computers to collect continuous analog data, convert data to digital form for processing, and display results on monitor. Discusses classroom advantages of these packages, describes one package for teaching harmonic motion, and provides a list of currently available packages (including vendor and…

Describes the history of, and research activities and current problems at Tsukuba Science City, Japan's new municipal complex of research laboratories and educational facilities. About 30 percent of Japan's government research laboratories, as well as Tsukuba University, are located in the complex. (JN)

Discusses implications of the recent actions of Federal agencies, through export control regulations, to control the open exchange of scientific ideas. Reactions of the National Academy of Sciences and several professional physics organizations are described. Impact on foreign students and publication is also discussed. (CS)

Describes the format and lists course content of a university-based workshop for elementary school teachers who require additional training because they may lack experience in performing experiments, demonstrations, and observations related to physics in elementary science courses. (Author/SK)

Presents NASA astronomy publications by subject: Earth; Moon; Mercury and Venus; Mars; Jupiter and Saturn; Planets (general); Comets, Meteors, and Asteroids; Sun; Astronomy from Various NASA Missions; Miscellaneous Astrophysics; Telescopes and Instrumentation; and Extra-Terrestrial Life. Includes listing of NASA Technical Conference Proceedings…

David Ausubel's learning theory was used as a framework for the content organization of an experimental Personalized System of Instruction (PSI) course in physics. Evaluation suggests that the combination of PSI as a method of instruction and Ausubel's theory for organization might result in better learning outcomes. (Author/JMD)
