The kinetics experiments on the ligand-C[subscript 60] exchange reactions on (dihapto-[60]fullerene) pentacarbonyl tungsten(0), ([eta][superscript 2]-C[subscript 60])W(CO)[subscript 5], form an educational activity for the inorganic chemistry laboratory that promotes graphical thinking as well as the understanding of kinetics, mechanisms, and the…

The oil drop experiment is considered an important contribution to the understanding of modern physics and chemistry. The objective of this investigation is to study and contrast the views and understanding with respect to the experiment of physicists or philosophers of science with those of authors of physics or chemistry textbooks and…

Propensity score analysis is one statistical technique that can be applied to observational data to mimic randomization and thus can be used to estimate causal effects in studies in which the researchers have not applied randomization. In this article the authors (a) describe propensity score methodology and (b) demonstrate its application using…

Undergraduate biology programs are currently undergoing reform to involve students in biomedical research. Engaging students in more active, hands-on experiments allows students to discover scientific principles for themselves, and to develop techniques of critical thinking and problem solving. This models the world of real scientific research,…

The IRT (Item Response Theory) has been studied and applied in computer-based test for decades. However, almost of all these existing studies evaluated focus merely on test questions with text-based (or static text/graphic) type of presentation form illustrated exclusively. In this paper, we present our study on test questions using both…

The purpose of this study was to investigate value of combining Real Experimentation (RE) with Virtual Experimentation (VE) with respect to changes in students' conceptual understanding of electric circuits. To achieve this, a pre-post comparison study design was used that involved 88 undergraduate students. The participants were randomly assigned…

This study attempts to reconcile viewpoints on the role of errors in the design of computer-based training (CBT) systems. From one perspective, errors are detrimental to learning; from another, they can be beneficial. The results of an experiment are presented and discussed. When a CBT system is designed to allow learners to correct their own…

McCarthy (1985) constructed the 4MAT teaching model, an eight step instrument developed in 1980, by synthesizing Dewey's experiential learning, Kolb's four learning styles, Jung's personality types, as well as Bogen's left mode and right mode of brain processing preferences. An important implication of this model is that learning retention is…

Teaching is essentially a personal and professional business in which lively, thinking, enthusiastic teachers continue to analyze their own activities and mediate the curriculum framework to their students. This book aims at encouraging teachers and curriculum developers to continue to rethink how science and technology should be taught in…

The purpose of the Toys in Space project was to create new ways for children to discover the joy and excitement of science and technology in the world around us. This book describes how familiar toys behave in the space environment where the downward pull of gravity is absent, and clearly documents those principles of physics that explain why the…

Project WET (Water Education for Teachers) is a nonprofit water education program for educators and young people. This curriculum and activity guide for kindergarten through twelfth grades is a collection of innovative, water-related activities that are hands-on, easy to use, and fun. The activities incorporate a variety of formats such as large…

This book is designed to help students understand the nature of scientific inquiry by involving them in doing science rather than merely reading about it. The content of the text emphasizes science process skills, mathematical skills, and the use of theories and models that are fundamental for learning the various science disciplines. The…

Males are more likely than females to aspire to and attain careers in science. This pattern might be attributed to differences in the appeal of school science to boys and girls. In this study, 114 middle school students in grades 7 and 8 carried out versions of science experiments that differed in their motivational appeal. Findings showed that…

Instruction in Scientific Inquiry Skills (ISIS) is part of a seven-year Air Force effort--the Fundamental Skills Training Project--to design, build, evaluate, and transition advanced computer-aided instruction to the education community. This report describes ISIS 2.0 and presents the results of an initial field evaluation of the software during…

The development of the "Directories of Unpublished Experimental Mental Measures" is traced. Two decades ago, the senior author of this research began the compilation of a list of non-standardized experimental test instruments developed by behavioral and social sciences researchers. Making this information available was intended to help…
