Reports results of a public opinion survey aimed at measuring the general public's understanding of scientific concepts, and acceptance of scientific paradigms. Assessment and analysis by science and society experts is provided. (JM)

The key to learning is student involvement! This American Association of Physics Teachers/Physics Teaching Resource Agents (AAPT/PTRA) manual presents examples of two techniques that are proven to increase student involvement in your classroom. Based on the "5E" model of learning, exploratories are designed to get your students excited about the…

This study aimed to help the teachers clarify and understand the nature of science (NOS), as well as classroom practice through the implementation of the constructivist teaching model. Ten elementary science teachers were involved in a year-long in-service program that included a series of intervention courses. Following the intervention courses,…

Traditional applications of history and philosophy of science in chemistry education have concentrated on the teaching and learning of "history of chemistry". This paper considers the recent emergence of "philosophy of chemistry" as a distinct field and explores the implications of philosophy of chemistry for chemistry education in the context of…

The purpose of this study was to investigate aspects of the Nature of Science (NOS) concepts and teaching practices acquired by inservice teachers who participated in a teacher education program at the National Changhua University of Education in Taiwan. Two instructors used both case-history and demonstration approaches to help science teachers…

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)
