Biology teachers can provide lessons for students to help them plan the future wisely. Three natural laws are emphasized as imperative to understanding how to plan wisely for restoring a balance in nature. (SA)

Discusses problem-solving strategies and the successful strategy used to solve stoichiometric problems in general college chemistry courses. Reports that rereading problems, recalling a related concept, and reasoning deductively/inductively are the most heavily used strategies among 13 categories. (YP)

Presents an experiment to show the energy conservation principle using a bow. Describes how to measure the force and work of the bow and the initial velocity of an arrow. (YP)

Introduces three laboratory exercises which develop an understanding of principles of mechanics by using examples of bicycle operation: Newton's laws, statics and dynamics, and energy relationships. Describes related theory and laboratory procedures with diagrams and pictures in each exercise. (YP)

Presents an examination of the buoyancy principle which can serve as a simple but rigorous illustration of a falsification test that not only clears up a possible misconception but also points the way to a number of practical uses of buoyancy measurements that have not generally been recognized. (MVL)

The grading of high school physics students as a function of conceptual versus nonconceptual performance is investigated. The nonconceptual means a routine substitution in equations or direct recall. Students scoring highest on one type of question are far from distinguished on another type of question. (YP)

Reviewed are two computer software programs for Apple II computers on weather for upper elementary and middle school grades. "Weather" introduces the major factors (temperature, humidity, wind, and air pressure) affecting weather. "How Weather Works" uses simulation and auto-tutorial formats on sun, wind, fronts, clouds, and…

Discusses the mechanism and the change of pH during the reaction. Notes that a dramatic rise in pH occurs when the reaction nears completion. Evaluates theories by other authors. (MVL)

Examined the evolution of the knowledge and the notions of students in order to see how after one year of university study their concepts and ideas of scientific theory in chemistry had progressed. Reports that sometimes the students' conceptions are modified in the wrong way. (Author/YP)

Legal and educational aspects of the debate over religious expression entering the college classroom are examined, particularly as they relate to inclusion of creationism into science instruction. It is concluded that the central question is not whether creationism is religious, but whether it is true, and that truth benefits from open debate over…

Explores the views of Japanese students (N=2478) concerning the nature of science, technology, and society via a questionnaire. Discusses the results within the context of Japanese culture. (DDR)

Argues that epistemic and cultural values guide scientific progress and that the social structure of science is strengthened by a diversity of values. Claims that science exports values to the larger culture. Reasons that science teachers who understand the multifaceted relationship between science and values can more effectively guide students in…

Traces the history of legal rulings leading up to the Edwards vs. Aguillard decision by the Supreme Court that it is unconstitutional to mandate "balanced treatment" and "equal time" for teaching creationism along with evolution in school science classes. Contains 17 references. (WRM)

Argues that science students often perceive physical events, the nature of scientific knowledge, and the nature of learning processes in different ways from science teachers and scientists, and that science teachers need to account for these differences in planning their science teaching. Contains 40 references. (WRM)
