Students enrolled in a large-lecture, non-majors biology course employing a diversified instructional approach featuring both instructor-centered and student-centered techniques evaluated the effectiveness of each approach in fostering course goals. Students perceived both approaches to be effective to some extent. Students indicated that the…

A tentative classification of internal departments of psycholinguistics is suggested and a list of applied fields is presented. Applied psycholinguistics is not seen here to have a right to scientific independence. (SCC)

The preservation of variation in plural societies as a step toward increasing evolutionary potential through a model of incorporative change is proposed as a procedural ethic with the special virtue of placing moral decision making in the hands of those who will be undergoing change. (JC)

In this note, we introduce a simple homemade toy called the brush-creeper, which can glide forward with no propellers, limbs, wheels, and seemingly no movement of any kind that can push forward against the ground. The toy arouses pupils' interest and their incentive to ask "Why?" in lessons related to friction.

The conceptual steps that first led Galileo toward his principle are reconstructed showing that his thoughts on the subject of motions that are neither natural nor forced were of fundamental importance. (MP)

The author argues that the scientific method, as it is commonly understood, is a myth. (BD)

Recognition of the logic of Darwin's explanation has significance for understanding evolution and for appreciation of the extent to which Darwin's concept of evolutionary mechanism accords with modern evolutionary thought. Darwin's explanation exemplifies the concept of a scientific law and can help learners to understand the nature of scientific…

The argument presented here, against the principle of uniformitarianism as a means of transforming an inductive argument into a deductive one, is based on the fact that this principle is itself established by inductive reasoning. (MDR)

This article reviews the discovery of the first of the metallocenes and some of the developments which have taken place in the 25 years following. Applications to topics such as the solution of the polyphenylchromium problem and Alkene polymerisation, are discussed. Ferrocene is studied in detail. (MA)

Discusses the difficulty of predicting wave structure of two phase gas-liquid flow in pipes. (SL)

Responds to Shields' paper (1986) on the structure of new epistemologies in family therapy. Contends that Shields is being reductionistic in his criticism and obscures the importance of epistemology in family therapy. Also sees problems in Shields' assumptions of objectivity and veracity. (Author/ABB)

The authors criticize the value-free notion of social science and evaluation. They particularly assail relativists, those who confuse the making of reliable value judgments with how these value judgments are used. (Author/PN)

The National Research Council (NRC) (1996) refers to scientific inquiry as "the diverse ways in which scientists study the natural world and propose explanations based on the evidence derived from their work." This could be paraphrased, as 'scientific inquiry is what scientists say it is.' Accepting this rephrasing at face value, a study has been…

The ability to become a scientifically literate citizen rests on the foundation students build from elementary, middle, and high school science experiences. The North Carolina Science Standard Course of Study (SCS) provides the concepts and theories all students should understand. Strands unify the goals and objectives and reflect a science as…
