This study focuses on the integration of protocols into elementary school English teacher’s professional dialogue and discusses the influence of protocols on teacher’s teaching and learning. Based on the analysis of documents, observations, and interviews, this study concludes that the introduction of protocols to elementary school English teachers led them to discuss their classroom practice and gain professional learning in instructional strategies and student learning during the professional dialogue. However, English teacher’s lack of experience in using protocols led to interruptions during the professional dialogue. Suggestions for effective protocol-based professional dialogue are provided.
OBJECTIVE: Women with histories of childhood maltreatment (CM) have higher rates of physical health problems and greater medical utilization compared to women without abuse histories. This study examined whether current post-traumatic stress disorder (PTSD) symptoms mediate the relationship between CM and indicators of physical health and medical utilization in female veterans. METHOD: Respondents were 221 female veterans (56% of the potential sample), who received medical care from the San Diego VA Healthcare System during a 12-month period. Respondents provided self-report information about CM, PTSD symptoms, use of pain medication, and physical symptoms and functioning. Additional information about medical utilization was extracted from respondents' medical charts. Regression-based models were conducted to test whether PTSD symptoms mediate the relationships between CM and physical symptoms and between CM and medical utilization. RESULTS: Emotional abuse was associated with poorer role-physical functioning, increased bodily pain and greater odds of using pain medication in the past 6 months. Physical abuse was associated with poorer general health. Contrary to prediction, emotional neglect was associated with better role-physical functioning, and CM was not associated with increased healthcare utilization. PTSD was shown to mediate the relationship between emotional and physical abuse and health outcomes. CONCLUSIONS: PTSD, or psychopathology more generally, appears to be an important factor in the negative health impact of CM. Given that several empirically supported interventions are available for PTSD, there may be physical health benefits in early identification and treatment of psychopathology related to CM. 相似文献
This paper describes three imperatives for collection inventory work at the University of Canterbury (UC) Library. Learning experiences from UC Library's first full inventory in 2005 were used to develop a regular and sustainable method of conducting future inventories. The first need for inventory arose as a result of an organized crime ring that targeted valuable books in libraries throughout New Zealand. Findings from library customer surveys in 2003 and 2005 gave rise to a second imperative which was to take prompt, proactive action regarding items missing from the shelves. As UC Library begins moving items to offsite storage, a third imperative arose for correctly accounting for what UC Library actually holds. As pressure comes on staffing resources this additional and significant collection management task has had to be achieved without extra staff. Good communication, clarity of responsibilities and breaking down the work into manageable amounts all became vital to the overall success of managing inventory work. 相似文献
The current article represents a methodological proposal. It seeks to address the question of how one might recognize a discovery as a discovery without knowing in advance what is available to be discovered. We propose a solution and demonstrate it using data from a study previously reported by J. Roschelle (1992)Roschelle, J.1992. Learning by collaborating: Convergent conceptual change. Journal of the Learning Sciences, 2: 235–276. [Taylor & Francis Online], [Google Scholar]. Roschelle investigated 2 students' developing understandings of certain abstract features of Newtonian mechanics while working within a computer-based microworld, the Envisioning Machine. We employ an approach we term discovery as occasioned production to reexamine his data. Such an approach proceeds stepwise from the identification of some matter discovered, working backward to see just where that matter entered the conversation and then, finally, tracing from that point forward to illuminate how the proposal for a possible discovery was ultimately transformed into a discovery achieved. The notion of “evident vagueness,” borrowed from H. Garfinkel, M. Lynch, and D. Livingston's (1981)Garfinkel, H., Lynch, M. and Livingston, D.1981. The work of discovering science construed with materials from the optically discovered pulsar. Philosophy of Social Science, 11: 131–158. [Crossref], [Web of Science ®], [Google Scholar] account of the discovery of an optical pulsar, emerges as an important feature of our analysis. Following H. Garfinkel (2002)Garfinkel, H.2002. Ethnomethodology's program: Working out Durkheim's aphorism.Lanham, MD: Rowman & Littlefield.. [Google Scholar], we present our findings as a “tutorial problem” and offer a suggestion for how a program of practice studies in the learning sciences might be pursued. 相似文献
This study examines the effects of the activity of building systems models for school-based problems on problem solving and on conceptual change in elementary science classes. During a unit on the water cycle in an Asian elementary school, students constructed systems models of the water cycle. We found that representing ill-structured problems as system models improves problem solving as well as creating beneficial conceptual change related to the topic. 相似文献
Characteristics of 13 doctoral programs in criminal justice and criminology are examined. Features described include the age and size of the programs, representation of women and minorities among faculty and graduate students, admissions requirements and admissions activity, financial support available to graduate students, and characteristics of the curricula. Criminal justice doctoral programs vary widely on each of these characteristics. 相似文献
This paper looks at the conceptual differences between video game learning and traditional classroom and laboratory learning. It explores the notion of virtual experience by comparing a commonly used high school laboratory protocol on DNA extraction with a similar experience provided by a biotechnology themed video game. When considered conceptually, the notion of virtual experience is not limited to those experiences generated by computer aided technology, as with a video game or computer simulation. The notion of virtuality can apply to many real world experiences as well. It is proposed that the medium of the learning experience, be it video game or classroom, is not an important distinction to consider; instead, we should seek to determine what kinds of meaningful experiences apply for both classrooms and video games. 相似文献
