Describes the content, structure, development, and educational use of an advanced interactive videodisc for teaching ecology. Discusses how the disc enables students to visit a real place and move around in time and space to investigate, sample, analyze, and test possible ideas within the environment. (CW)

Reports on the results of an investigation into the understanding of the concepts of basic electricity by French students from grade six up through the fourth year of college. Discusses the misconceptions formed and the challenges these present to physics educators. (TW)

Discusses combustion by suggesting several experiments and demonstrations using matches. Integrates quotes from famous scientists about the various phenomenon regarding combustion. (TW)

Proposes the use of a relative atomic mass (RAM) scale in which hydrogen is assigned a value from one as a teaching aid for better understanding the concept of RAM. Helps to clarify the ideas and concepts about this topic. (CW)

Describes the Interactive Microcomputer Peripheral (including major features, source, and current cost) and physics experiments using the instrument. The instrument can also be used for such purposes as counting, timing, and frequency measurement as well as for experiments in biology and experimental psychology. (JN)

Explores the relationship between teaching and socialization through a case study report of the classrooms of three junior-high science teachers. Provides a brief characterization of socialization and the substance of science teaching and discusses the factors which appear to be relevant to these characterizations. (ML)

Explores the issue of the consistency of use of students' conceptions across different tasks which probed understandings of aspects of pressure, heat, and biological evolution. Findings indicate that children have alternative frameworks for all investigated areas. (ML)

Presents a model for planning the measurement of physical quantities. Provides two examples of optimizing the conditions of indirect measurement for laboratory experiments which involve measurements of acceleration due to gravity and of viscosity by means of Stokes' formula. (ML)

This study examined 12th-grade biology students' opinions and beliefs on the desirability of the use and/or development of various biotechnologies. Describes the development of and presents results from the three questionnaires employed in the study. Includes a listing of the 15 biotechnology topics investigated in the study. (ML)

Reports on Nigerian students' attitudes towards science. Findings suggest that students in general have a favorable attitude towards science and that exogenous factors such as family background and religion do not affect attitudes, whereas school and type of school attended (single-sex) affected attitude. Males were more positive than females…

Discusses a study that examined which reasoning patterns are necessary for success in high school chemistry. Based on student (N=170) scores from the "Classroom Test of Formal Reasoning," it was revealed that students who use formal reasoning patterns are capable of greater achievement in chemistry. (ML)

Describes a technique which gives an automatic and accurate assessment of photosynthetic oxygen liberation with graphical results available immediately. This program takes readings from an oxygen electrode and a photocell simultaneously. The types of results and unique features of the technique are discussed. (ML)

Offers perspectives on the need for secondary science curriculum reform. Discusses curriculum issues in terms of four stages which include: the nature of science; principles of curriculum design; pupils needs and entitlements; and practical proposals for exploring curriculum models. (ML)

Upholds the importance and need for including visuo-spatial skill exercises in science lessons. Provides suggestions for improving students' visualization skills and reviews the approaches that have been successful with students who were poor in visual skills. (ML)

Defies the assumption that laboratory teaching skills are gained by preservice secondary science education majors through their undergraduate science programs, and presents expertise areas which every teacher should possess. Outlines activities for each skill which can become part of a methods course under the direction of science educators. (DH)
