The author presents an analysis of alternative views about why students should learn science, shares some anecdotal impressions about the heuristic potential of the concept "curriculum emphases" in a practical setting, and examines some problems related to teaching science to early adolescents. (Author/PB)

Investigates the misconceptions in physics among South African students. The physics test which was administered to selected high school and college students is included. (HM)

This study, conducted in an Australian institution, investigates the intellectual requirements of the mechanics section of a first-year college physics text. Instructional and prerequisite concepts were classified in terms of the intellectual skills required to understand them. (HM)

This study compared effects of two approaches to hands-on science, supported inquiry science (SIS) and activity-based science, in six urban and two suburban fourth-grade general education classrooms involving 172 students, 33 of whom had learning disabilities (LD). The study found that students with and without LD demonstrated greater concept…

A study with nine physics students in a Quebec university found they saw themselves learning primarily outside the classroom as they solved assigned problems, saw few new concepts being introduced, and felt they had moved beyond memorization to application of concepts to problem solving. Students' perceptions were sometimes at odds with teachers'…

Describes a unit for the first grade that takes advantage of the fall seasonal changes to explore, be creative, and learn. Ties all the subject areas together through a look at leaves and trees. A list of resources is included. (JRH)

Describes the development of a 3-D virtual environment for secondary school and college physics and chemistry. Discusses individual learning styles; the effectiveness of visual stimuli in science education; implications of visual learning in designing instruction for differences in learning styles; and conceptual understanding. (LRW)

Presented is background material on Galileo and his views on astronomy, religion, and Copernicus. The history of theory development related to the science of astronomy and a review of Galileo's writings are included. (KR)

Points out a misconception that is reinforced in many elementary and advanced chemistry texts. Discusses the general limitations of the orbital concept. Notes misconceptions related to the transition elements and their first ionization energies. (MVL)

Reports on an attempt to bring about conceptual change in children's concept of speed by the teaching of the science of speed emphasizing an integrated hands-on experience. Reports that it may be possible to modify naive conceptions by teaching that targets particular concepts. (Author/YP)

The Learning in Science Project (Energy) was designed to investigate teaching and learning about the energy concepts of New Zealand elementary and secondary students. Discussed are aspects of an approach to teaching energy to low ability students in physics. (YP)

Presents the mechanistic ideas underlying reactions between nucleophiles and carbonyl compounds as well as some popular misconceptions. Relates reactions of carboxylic acid derivatives to those of aldehydes and ketones. Discusses leaving group ability and the ability of carbonyl oxygen to accept a negative charge. (Author/MVL)

Illustrates the basis for misleading statements about the relationship between pH and acid content in acid rain. Explains why pH cannot be used as a measure of acidity for rain or any other solution. Suggests that teachers present acidity and pH as two separate and distinct concepts. (RT)

Presents several fun activities and teacher demonstrations which simplify terms and condense science concepts for teaching about the lever, wedge, wheel and axle, screw, pulley, and the inclined plane. Includes objectives, materials, procedures, suggested follow-up assignments, and diagrams. (RT)

Presents a method to teach stoichiometry where a problem is broken down into four factors and two cycles. Offers grams of known, moles of known, moles of unknown, and grams of unknown as the factors. Uses factor labeling as the second cycle. (MVL)
