Can use of technology make a difference in student learning? Although a considerable literature describes its advantages in conceptual terms, research documenting its effective use in this context is limited. The purpose of this study was to examine the effects of a graduate-level Web design activity on student attitudes toward learning. Students…

In this article we describe the development of the Chemistry Attitudes and Experiences Questionnaire (CAEQ) that measures first-year university chemistry students' attitude toward chemistry, chemistry self-efficacy, and learning experiences. The instrument was developed as part of a larger study and sought to fulfill a need for an instrument to…

In the last decade, voluntary efforts by firms to reduce their environmental impacts have received increasing attention from both policymakers and scholars. This article discusses polluters' incentives to reduce their releases. In particular, using data from Canada's National Pollutant Release Inventory, it examines the impacts of conventional…

This paper represents Part I of a two-part study examining preservice teachers' development of a personalized, research-based Science Teaching Rationale (STR). Researchers have historically documented the application of the "rationale paper" (Clough, 1992; Veronesi, 1998) using qualitative methodologies. Since the rationale paper continues to…

Enzyme kinetics is a difficult subject for students to learn and for tutors to teach. During the practicals included in the biochemical courses at the Faculty of Chemistry of Universidad Nacional Autonoma de Mexico, we found that the students acquire good training in the calculations to obtain kinetic parameters such as K[subscript m], V[subscript…

The "dual-channel" hypothesis (Lawton, 1996), which suggests the dual-antecedent pattern for positive and negative aspects of psychological well-being, was tested by examining the differential relationships between objective and subjective measures of family support (family contact, family quality, perceived importance of family) and…

Ultrasound can be used to address unresolved questions in phonological theory. To date, some studies have shown that results from ultrasound imaging can shed light on how differences in phonological elements are implemented. Phenomena that have been investigated include transitional schwa, vowel coalescence, and transparent vowels. A study of…

For individuals who have complex communication needs and for the interventionists who work with them, the collection of empirically derived data that support the use of an intervention approach is critical.

The study was carried out island-wide with the whole area divided into 10 districts, from which 4,537 students were selected using stratified random sampling. A questionnaire on…

The articles published in the "Measurement in Physical Education and Exercise Science" (MPEES) journal over the first 10 volumes were categorized by content area and methodology. The authors have offered opinions here concerning the changes observed over the 10-year period, the areas that are well-represented, and other potential areas of research…

This study was designed to address two frequent criticisms of the SAT essay--that essay length is the best predictor of scores, and that there is an advantage in using more "sophisticated" examples as opposed to personal experience. The study was based on 2,820 essays from the first three administrations of the new SAT. Each essay was…
