Researchers and practitioners alike express concerns about the conceptual difficulties associated with the concepts of momentum and kinetic energy currently taught in school physics. This article presents an in-depth analysis of the treatment given to them in 44 published textbooks written for UK secondary school certificate courses. This is set…

As an alternative guide to science teaching, a generalized theory of scientific observation defined in terms of human intentions and purposes is offered. The generalized theory, while based on assumptions different from those of the science education theory, can still account for the plausibility of many aspects of that theory. (JN)

The meanings of eight science terms (volume, organism, motion, energy, molecule, cell, enzyme, fossil) were studied by 9-, 13-, and 17-year-olds. Results indicate that the schools were ineffective in increasing numbers of students who mastered these terms between seventh and eleventh grade. Reasons for this finding are discussed. (Author/JN)

Visits to six school districts which were identified by the National Science Teachers Association's Search for Excellence program were made during 1983 by teams of 17 researchers. Their reports were analyzed in search for common characteristics that can explain the requirements necessary for excellent science programs. These characteristics are…

Results from studies dealing with students' views toward science teachers/classes, usefulness of science study, and what it is like to be a scientist are reviewed and analyzed. Studies include National Assessment of Educational Progress data and data from an Iowa follow-up study and a study of a large school district. (JN)

Investigated visuo-spatial ability of a control group and an experimental group (receiving 30 minutes of interaction each week) in undergraduate college biology. Results for the subjects (N=84) indicate that visuo-spatial aptitude can be enhanced through teaching. (Descriptions of interaction sessions and explanations of tasks are included.) (DH)

Investigated gender patterns with respect to entry rate, project topic, and project type in a state-level science competition. Reports that for the past 20 years the participation rate has been greater for girls than for boys. Boys are more likely than girls to prepare physical, earth, math/computer, and experimental research-based projects. (45…

Reports on the results of a study designed to examine what middle and high school science teachers believe should be the goals for science education for the remainder of the 1980s. Respondents compared modern science education goals with those of the 1960s. (TW)

Reports on a study designed to focus on staff development delivery variables in the context of science teacher workshops. Data suggest that 8 to 16 hours is a minimum amount of time for staff development if teachers are to implement new strategies into their science classrooms. (TW)

Describes Diagnosis for Instruction in Problem Solving (DIPS), a new line of research for science educators interested in interdisciplinary efforts and ways in which computer technology might be used to better understand how to improve science teaching. Outlines the basic architecture of DIPS in terms of instruction and research implications.…

Reports on a study conducted in the Richardson Independent School District (Texas) which was designed to assess the attitudes toward science of students and teachers who have been involved with the Science Curriculum Improvement Study (SCIS) compared to non-SCIS students and teachers. (TW)

Identifies two stages in research on scientific literacy; a composite saturation stage in which definitions covered all objects of science education, and a stage when researchers focused on small manageable portions of scientific literacy. Describes formal, nonformal, and informal science teaching. (TW)

Discusses instruments for measuring interest in biology: "Interest in Science Topics"; "Learning Mode Preference"; "Interest in Scientific Activities"; "Activities Motives Inventory"; "Interest in Social Aspects of Science"; "Career Orientation Inventory"; and "Attitude toward Biology Study." Concludes that interest in biology may be…

This was an experiment to test the extended discretion laboratory approach versus a guided-inquiry approach for teaching biology in a university setting. Among three criterion variables (examination, reports, and quizzes), only the laboratory report scores showed differences between groups and group-by-instructor interaction. (Author/YP)

Calls for differentiating between three kinds of studies of students' conceptions in science, namely descriptive studies, explanatory studies, and studies attempting to foster conceptual change. Cites the literature about student perceptions and science instruction. (TW)
