Students were linked virtually across three contexts: U.S., Malaysia, and China. Differences emerged in how student-created messages were constructed and interpreted; these impacted perceived relational affiliation. Messages constructed by students in Malaysia and China exhibited casual talk, greater self-disclosure, requests for personal information, and greater use of emoticons/emoji. Interactions were perceived as informal, friendly, and positive. U.S. students’ messages often showed institutional talk, less self-disclosure, and more attention to the instructor-assigned task. Asian-U.S. student pairs perceived their interactions as formal, less friendly, and less positive. This study shows how online technologies may be afforded and shaped by culture and interaction. 相似文献

Domain scores have been proposed as a user-friendly way of providing instructional feedback about examinees' skills. Domain performance typically cannot be measured directly; instead, scores must be estimated using available information. Simulation studies suggest that IRT-based methods yield accurate group domain score estimates. Because simulations can represent best-case scenarios for methodology, it is important to verify results with a real data application. This study administered a domain of elementary algebra (EA) items created from operational test forms. An IRT-based group-level domain score was estimated from responses to a subset of taken items (comprised of EA items from a single operational form) and compared to the actual observed domain score. Domain item parameters were calibrated both using item responses from the special study and from national operational administrations of the items. The accuracy of the domain score estimates were evaluated within schools and across school sizes for each set of parameters. The IRT-based domain score estimates typically were closer to the actual domain score than observed performance on the EA items from the single form. Previously simulated findings for the IRT-based domain score estimation procedure were supported by the results of the real data application. 相似文献

After 1.5 years of college, men and women engineering students in a population of 42 schools had different retention rates in engineering at their original schools. Based on a sample of students at 16 schools, the estimated population retention rates were 73.3% for men and 67.8% for women. This report discusses student characteristics that were related to retention for men or women, as well as the destinations of students who left engineering at their original schools. 相似文献

Diversity, multicultural education, equity, and social justice are dominant themes in cultural studies (Hall in Cultural dialogues in cultural studies. Routledge, New York, pp 261–274, 1996; Wallace 1994). Zeichner (Studying teacher education: The report of the AERA panel on research and teacher education. Lawrence Erlbaum Associates, Mahwah, pp 737–759, 2005) called for research studies of teacher educators because little research exists on teacher educators since the late 1980s. Thomson et al. (2001) identified essential elements needed in order for critical multiculturalism to be infused in teacher education programs. However, little is known about the commitment and experiences of science teacher educators infusing multicultural education, equity, and social justice into science teacher education programs. This paper examines twenty (20) Black science teacher educators’ teaching experiences as a result of their Blackness and the inclusion of multicultural education, equity, and social justice in their teaching. This qualitative case study of 20 Black science teacher educators found that some of them have attempted and stopped due to student evaluations and the need to gain promotion and tenure. Other participants were able to integrate diversity, multicultural education, equity and social justice in their courses because their colleagues were supportive. Still others continue to struggle with this infusion without the support of their colleagues, and others have stopped The investigators suggest that if science teacher educators are going to prepare science teachers for the twenty first century, then teacher candidates must be challenged to grapple with racial, ethnic, cultural, instructional, and curricular issues and what that must mean to teach science to US students in rural, urban, and suburban school contexts. 相似文献

Two studies were conducted to assess the effects of rapid eye movement (REM) sleep deprivation on shock-elicited aggression. REM deprivation periods of 0, 24, 48, and 72 h were used in the first study, while 48-, 72-, 96-, and 120-h periods were used in the second study. Both studies indicated that increases in REM deprivation (up to 96 h) resulted in increases in the number of aggressive responses. A decrease was shown by the 120-h group. A drive-energization or motivational-effects model is suggested. 相似文献

Understanding students' understanding of mathematical ideas can inform mathematics teaching, and task-based interviews are
one way in which teachers can learn more about their students' understandings. The CIME project was designed to empower mathematics
teachers to use interviews to understand their students' mathematical understandings as well as to prepare teachers to use
technology-intensive curricula. This study examined the influences on three high school mathematics teachers as they learned
to use task-based interviews to understand students' mathematical understandings. The areas of teacher knowledge and conceptions
that influenced the teachers we studied were: teachers' mathematical understandings and knowledge of technology and the perceived
importance of curriculum topics; teachers' views of knowing mathematics; teachers' perceptions of students' characteristics
and needs; and teachers' perceptions of interviewing and the role of questioning in interviews.

Understandings of young children as active and capable citizens, while evident in discourses of early childhood education and research, are not widely reflected in the policy for the early years of schooling in Australia. This paper makes an analysis of the gaps and tensions between discourses of young children as active citizens and policy for citizenship education at the national level in Australia and at the Queensland State level. There is a widespread discourse within early childhood that regards young children as citizens and democratic participants in their own lives, as a reflection of the oft-cited Article 12 in the UN Convention on the Rights of the Child. However, educational policy and curriculum for citizenship in Australia, by and large, adheres to age and stage understandings of children that deem young children unable to conceptualise and/or articulate ideas of what it means to ‘be a good citizen’. We ask which discourses are being harnessed in educational policy for citizenship in Australia, what discourses are silenced or ignored and what this tells us about how young children are thought about in Australian politics and education. 相似文献

The purpose of this investigation was to measure the interface pressure exerted by lower body sports compression garments, in order to assess the effect of garment type, size and posture in athletes. Twelve national-level boxers were fitted with sports compression garments (tights and leggings), each in three different sizes (undersized, recommended size and oversized). Interface pressure was assessed across six landmarks on the lower limb (ranging from medial malleolus to upper thigh) as athletes assumed sitting, standing and supine postures. Sports compression leggings exerted a significantly higher mean pressure than sports compression tights (P < 0.001). Oversized tights applied significantly less pressure than manufacturer-recommended size or undersized tights (P < 0.001), yet no significant differences were apparent between different-sized leggings. Standing posture resulted in significantly higher mean pressure application than a seated posture for both tights and leggings (P < 0.001 and P = 0.002, respectively). Pressure was different across landmarks, with analyses revealing a pressure profile that was neither strictly graduated nor progressive in nature. The pressure applied by sports compression garments is significantly affected by garment type, size and posture assumed by the wearer. 相似文献
