Instrumental music education, as it evolved in the segregated African American communities and their educational institutions, remains an under-investigated area of historical research. As a partial remedy to that circumstance, this study sought to document one of the more noteworthy of such accounts, the history of instrumental music ensembles at…

This paper describes a simple, rapid and low-cost technique for growing bacteria (or other microbes) in an environmental gradient, in order to determine the tolerance of the microbial population to varying concentrations of sodium chloride ions, and suggests how the evolutionary response of a microbial population to the selection pressure of the…

In the present study, we investigated the association of anthropometric parameters with race performance in ultraendurance runners in a multistage ultraendurance run, in which athletes had to run 338 km within 5 consecutive days. In 17 male successful finishers, calculations of body mass, body height, skinfold thicknesses, extremity circumference,…

Electricity is regarded as one of the most challenging topics for students of all ages. Several researchers have suggested that naive misconceptions about electricity stem from a deep incommensurability (Slotta and Chi 2006; Chi 2005) or incompatibility (Chi et al. 1994) between naive and expert knowledge structures. In this paper we argue that…

Any curriculum consists of several components: goals, disposition, duration, needs analysis, learners and teachers, exercises and activities, resources, ways of learning, skills to be acquired, lexis, language structure, and ability assessment. Before setting up a program or course of study, these components should be determined and described in…

Despite the prevalence of dating violence, incidences often go unreported due to a lack of awareness among students as to appropriate dating behaviors. This phenomenology investigated how adolescents conceptualize and experience dating relationships. We explored adolescent females' definitions of healthy and abusive relationships, experiences with…

The need for additional nursing and health care professionals is expected to increase dramatically over the next 20 years. With this in mind, students must have strong biomedical science knowledge to be competent in their field. Some studies have shown that participation in bioscience laboratories can enhance science knowledge. If this is true, an…

Introduction: The aim of our research was to investigate the modality effect in more detail by measuring it in a direct way. Two studies were conducted using the same subject and material. Method: Computer-based learning material was presented on several screens, each containing a short text and a picture. Modality was varied by presenting written…

This paper investigates the impact of a two-year professional development program on teacher self-efficacy for inquiry-based instruction. The program utilizes scientist-teacher partnerships to develop content knowledge, inquiry-based instruction, and leadership skills for in-service STEM teachers. Participating teachers are administered a survey…

The context and nature of teacher efficacy beliefs provide a method upon which to explore science teachers' perceptions of their teaching effectiveness and student achievement as a function of ethnicity. Promotion of a more in-depth knowledge of science teaching efficacy requires cross-sectional and longitudinal investigations. In this study, a…

This study examines first graders' epistemic reasoning, in tacit "practical epistemologies" reflected in thinking about an investigation of their own design. I analyzed children's epistemic reasoning, following a design experiment scaffolding increasing regulation of scientific inquiry in a domain they studied in depth. Participants…

The Aging Network is a federally funded group of collaborating organizations which provides support and services to older adults and caregivers. Professionals within the network are charged with staying up-to-date on current best practices, pertinent changes in federal policies, and the latest developments in aging. To promote professional…

Nineteen PD patients who received deep brain stimulation (DBS), 10 non-surgical (control) PD patients, and 11 non-pathologic age- and gender-matched subjects performed sustained vowel phonations. The following acoustic measures were obtained on the sustained vowel phonations: correlation dimension (D[subscript 2]), percent jitter, percent shimmer,…

A priority for all biology teachers must be for students to leave the classroom with a broad knowledge and understanding of science. Students need to be critical of science, analyze science, and relate new science knowledge to their daily lives. Unfortunately, many students are not reaching this goal. One strategy for making science laboratories…

The overwhelming success of the commercial game market has brought increased attention to emerging work in educational game design. Much of the existing work in educational games has a strong similarity to the field of Problem-Based Learning (PBL), which has a rich history of conceptual literature as well as empirical investigations. Despite…
