This study was conducted to develop a simple and inexpensive experimental apparatus that can measure the position of an object moving along a straight line at certain time intervals. For the construction of the apparatus, a battery-powered toy car, a fine-tipped paint brush, gouache (or watercolour) paint and paper tape were used. The working…

Systems thinking suggests that one can best understand a complex system by studying the interrelationships of its component parts rather than looking at the individual parts in isolation. With ongoing concern about the effects of climate change, using innovative materials to help students understand how Earth's systems connect with each other is…

The purpose of this study was to investigate whether participating in science, technology, engineering, and mathematics (STEM) project-based learning (PBL) activities effected students who had varied performance levels and to what extent students' individual factors influenced their mathematics achievement. STEM PBL has been a critical challenge…

As secondary students' interest in science is decreasing, schools are faced with the challenging task of providing adequate instruction to engage students--and more particularly the disadvantaged students--to learn science and improve their science inquiry skills. In this respect, the integration of Web-based collaborative inquiry can be seen as a…

We designed and implemented curriculum intended to be used by students in an algebra-based introductory physics laboratory course. Our curricular goal was to foster, through observations in the lab, a coherent framework in students' understanding of general principles presented in the introductory mechanics course, while addressing known student…

English language learners (ELLs) often find themselves marginalized with respect to learning mathematics in U.S. schools due, in part, to language barriers and gaps in prerequisite math knowledge and skills. The goal of this study was to use Sen's (1980, 1992, 1999) capabilities approach model as a lens through which to analyze the relationship…

This usability study evaluated users' perceptions of a multimedia prototype for a new e-learning tool: Anatomy of the Central Nervous System: A Multimedia Course. Usability testing is a collection of formative evaluation methods that inform the developmental design of e-learning tools to maximize user acceptance, satisfaction, and adoption.…

This paper reports a study to develop a measure that would determine behaviors teachers predict they would use while teaching elementary school science. The Predicted Role Measure (PRM) consisted of a motion picture film and a response packet. After observing nine scenes from the film, the participating teachers recorded their predicted behaviors.…

This study was designed to determine experimentally the relationship between achievement and grade level for 64 tenth-grade students, 48 eleventh-grade students, and 95 twelfth-grade physics students. All students were enrolled in the Project Physics course in their respective schools. The Physics Achievement Test (PAT) and the algebra I and II…

The purpose of this study was twofold: first, to answer the question of which abilities, from a selected set of 12 abilities from the structure-of-intellect model of Guilford, were related to achievement in Physical Science Study Committee (PSSC) physics, and, second, to determine how the physics achievement prediction properties of these…

Reported is an investigation done to obtain descriptive answers to such questions as: What variables influence high school students' willingness to become personally involved with scientific activities? What variables influence these students' perception of the scientist? The study is described and includes an extensive review of the literature…
