This study revamps and optimizes the teaching and learning process and instrument for the classic binary vapor-liquid equilibrium experiment by combining activity coefficient model simulations and practical exercises. Our teaching process combines a software simulation and practical exercises. Utilizing Aspen software, students can predict phase…

A comparison of three methods used in teaching science with a discussion of the meaning of these terms and the psychological assumptions which are used to justify them. (DF)

Presents the rationale behind the need to teach the metric system and includes a description of the most important metric units. The stages through which children pass as they develop an understanding of the process of measurement are discussed. Bibliographic material is included. (EB)

This article presents a practical model for a biology classroom discussion on evidence and inference, and on changes that have taken place in accepted ideas of what constitutes reliable evidence. (EB)

Describes three major difficulties plaguing most discovery-learning teaching systems and presents a theoretical operational approach for offsetting these difficulties. (SL)

Describes an exploratory activity leading preschool children to become acquainted with the concept of time. (Author/EB)

Stresses the value of encouraging students to question the results of both obvious and the less obvious scientific activities. A simple science activity built on chemical reactions. (EB)

This study compared two groups of high school biology students and teachers with respect to teaching method and resultant behavior, learning climate, and achievement. The use of an open-inductive method yielded significantly different results from the traditional deductive method of instruction. (JR)

Distinguishes between problems" and exercises" in science teaching, and disscusses the use and abuse of problem-solving in physics instruction. Suggests that the essence of problem-solving is the element of creativity and challenge. The implications of this idea for science teaching is discussed. Bibliography. (LC)

This article presents a review of the experimental studies that have been conducted to determine the effectiveness of discovery learning as compared to expository learning in science and mathematics. The limitations of these studies are noted and some suggestions for future research are proposed by the author, who is an assistant professor of…

Describes exploratory activities for a young child seeking to become acquainted with the world in which he lives. (EB)

Reports on a part of a report on primary schools in England. States that science instruction tends to be superficial, and that the teaching and the content require more planning. (GA)

This paper provides a log and discussion of experiments conducted by a five-and-one-half-year-old child under the direction of the author. (SD)

Three activities for involving students in projects that incorporate writing, drawing and recording their findings are included. The discovery approach is emphasized. (EB)
