Technology education students: e-tutors for school children

E-tutoring refers to individualised learning support mediated by Internet technology. While increased demand for tutors has led to a surge in commercial e-tutoring services, volunteer e-tutoring programs for children are rare. To test the viability of volunteer e-tutoring for elementary school students, 10 undergraduate students enrolled in a technology education (TE) course provided online with instructional support to children in need of tutoring services. Each e-tutor was assigned a specific child, developed a Web Course Tools course and corresponding online activities to improve teacher-identified skill deficiencies, and provided 8 weeks of e-tutoring. Three video conferences complemented online instructional interaction between e-tutor and e-tutee. Children, parents and TE students expressed positive evaluation of the initiative.     

The 2010 Horizon Report: Museum Edition

Abstract The 2010 Horizon Report: Museum Edition examines emerging technologies for their potential impact on and use in education and interpretation within the museum environment. The report is based on conversations and dialogues with technology and museum professionals from more than two‐dozen countries.     

Explorable three‐dimensional digital model of the female pelvis,pelvic contents,and perineum for anatomical education

The anatomy of the pelvis is complex, multilayered, and its three‐dimensional organization is conceptually difficult for students to grasp. The aim of this project was to create an explorable and projectable stereoscopic, three‐dimensional (3D) model of the female pelvis and pelvic contents for anatomical education. The model was created using cryosection images obtained from the Visible Human Project, in conjunction with a general‐purpose three‐dimensional segmentation and surface‐rendering program. Anatomical areas of interest were identified and labeled on consecutive images. Each 2D slice was reassembled, forming a three‐dimensional model. The model includes the pelvic girdle, organs of the pelvic cavity, surrounding musculature, the perineum, neurovascular structures, and the peritoneum. Each structure can be controlled separately (e.g. added, subtracted, made transparent) to reveal organization and/or relationships between structures. The model can be manipulated and/or projected stereoscopically to visualize structures and relationships from different angles with excellent spatial perception. Because of its ease of use and versatility, we expect this model may provide a powerful teaching tool for learning in the classroom or in the laboratory.

Situated Learning: Conceptualization and Measurement

A focus on the interaction between cognitive schemas and context in situ has been suggested as fundamental in organizational decision making and information interpretation. Past research suggests that the situation and the social interaction that occur during learning at the cognitive level consist of factors that affect the process, but the research lacks a coherent explanation for how those factors affect it. We propose a conceptualization of learning, termed situated learning, which accounts for these factors. By drawing on situated cognition theory, social learning theory, and the theory of mental models, we identify and measure four components of situated learning, that is, thematic focus, cognitive absorption, social structure, and participation. Among the most important lessons for researchers and practitioners is the need to consider learning as a constellation of the four components instead of an indivisible phenomenon. This perspective can enhance our understanding of cognitive processes, such as information interpretation and decision making.     

Class Size and Student Performance at a Public Research University: A Cross-Classified Model

This study addresses several methodological problems that have confronted prior research on the effect of class size on student achievement. Unlike previous studies, this analysis accounts for the hierarchical data structure of student achievement, where grades are nested within classes and students, and considers a wide range of class sizes across various disciplines. Based on data from undergraduate class sections at a single institution, the study provides consistent evidence of a negative effect of class size on grade performance, most substantially affecting the achievement of “A” grades with lesser effect on grades of “C” or higher. Because models with logarithmic specification show superior fit, this study also demonstrates that the effect of class size on students’ final grades diminishes as the class size increases. These findings suggest that a larger impact on student performance could be attained by further trimming enrollment in small classes than by reducing class size overall.
