Risk Assessment and Optimisation of Blast Mitigation Strategies for Design and Strengthening of Built Infrastructure     

STEWART Mark G 《天津大学学报(英文版)》2006,12(Z1)

A probabilistic risk assessment procedure is developed which can predict risks of explosive blast damage to built infrastructure, and when combined with life-cycle cost analysis, the procedure can be used to optimise blast mitigation strategies. The paper focuses on window glazing since this is a load-capacity system which, when subjected to blast loading, has caused significant damage and injury to building occupants. Structural reliability techniques are used to derive blast reliability curves for annealed and toughened glazing subjected to explosive blast for a variety of threat scenarios. The probabilistic analyses include the uncertainties associated with blast modelling, glazing response and glazing failure criteria. Damage risks are calculated for an individual window and for windows in the facade of a multi-storey commercial building. The paper shows an illustrative example of how this information, when combined with risk-based decision-making criteria, can be used to optimise blast mitigation strategies.  相似文献   

English language teachers becoming more efficacious through research engagement at their Turkish university     

Mark Wyatt  Kenan Dikilitaş 《Educational Action Research》2016,24(4):550-570

While it is generally recognized that teacher research can be a very beneficial form of continuing professional development (CPD), there is still relatively limited research available on the impact this activity has on teachers’ self-efficacy beliefs, which are of interest to educational psychologists because, while being open to constant change, these beliefs influence the way in which knowledge is transformed into action. There is also a relative lack of available research into how teachers develop as researchers; the processes whereby they gain practical knowledge and more positive self-efficacy beliefs in planning, conducting, analysing, presenting and writing up research require further exploration. This qualitative multi-case study addresses these issues, exploring the development of three in-service teachers of English on a foundation programme at a Turkish university. Findings reveal that engaging in CPD which directly benefited their learners helped all three teachers develop positive teachers’ self-efficacy beliefs and deeper practical knowledge in relation to the specific tasks that concerned them. Furthermore, from a starting point of having low self-efficacy beliefs in conducting practical research, which reflected their lack of prior knowledge in this area, they all became more efficacious as they gained research experience and developed practical knowledge of research. This study highlights the benefits, then, of helping teachers become more efficacious through CPD that engages them as knowledge-generators. Enthusiastic mentoring, autonomy support and the opportunity to present their research more widely all helped the teachers in this Turkish context to develop.  相似文献   

Counterintuitive effects of online feedback in middle school math: results from a randomized controlled trial in ASSISTments     

Patrick McGuire  Shihfen Tu  Mary Ellin Logue  Craig A. Mason  Korinn Ostrow 《Educational Media International》2017,54(3):231-244

This study compared the effects of three different feedback formats provided to sixth grade mathematics students within a web-based online learning platform, ASSISTments. A sample of 196 students were randomly assigned to one of three conditions: (1) text-based feedback; (2) image-based feedback; and (3) correctness only feedback. Regardless of condition, students solved a set of problems pertaining to the division of fractions by fractions. This mathematics content was representative of challenging sixth grade mathematics Common Core State Standard (6.NS.A.1). Students randomly assigned to receive text-based feedback (Condition A) or image-based feedback (Condition B) outperformed those randomly assigned to the correctness only group (Condition C). However, these differences were not statistically significant (F(2,108) = 1.394, p = .25). Results of this study also demonstrated a completion-bias. Students randomly assigned to Condition B were less likely to complete the problem set than those assigned to Conditions A and C. To conclude, we discuss the counterintuitive findings observed in this study and implications related to developing and implementing feedback in online learning environments for middle school mathematics.  相似文献   

Educational Stratification and Students’ Social Bonding to School     

Mark Berends 《British Journal of Sociology of Education》1995,16(3):327-351

This paper examines the polarization model from qualitative research in both Great Britain and the US, which claims that educational stratification practices polarize students into pro- and anti-school orientations. Because few researchers have adequately conceptualized school attitudes and behavior, social bonding theory (Hirschi, 1969) is used to provide a framework for examining the polarization hypothesis. Relying on High School and Beyond data from the US, an attempt is made to develop measures of respondents’ social bonding to school, including college expectations, absenteeism, disciplinary problems, and engagement. The polarization hypothesis is supported by these US data when examining educational stratification effects on the school bonding measures. Compared to academic-track students, general- and vocational-track students have Iowa college expectations, more disciplinary problems, and are less academically engaged, controlling for prior school orientations and for selection bias due to dropping out of school. For absenteeism, the general track has a significant positive effect, while vocational-track students do not differ from those in the academic track. In addition, students in the nonacademic tracks are more likely to drop out of school between the 10th and 12th grades compared to academic-track students.  相似文献   

Folk theories of “inquiry:” How preservice teachers reproduce the discourse and practices of an atheoretical scientific method     

Mark Windschitl 《科学教学研究杂志》2004,41(5):481-512

Despite the ubiquity of the term “inquiry” in science education literature, little is known about how teachers conceptualize inquiry, how these conceptions are formed and reinforced, how they relate to work done by scientists, and if these ideas about inquiry are translated into classroom practice. This is a multicase study in which 14 preservice secondary science teachers developed their own empirical investigations—from formulating questions to defending results in front of peers. Findings indicate that participants shared a tacit framework of what it means to “do science” which shaped their investigations and influenced reflections on their inquiries. Some facets of the participants' shared model were congruent with authentic inquiry; however, the most consistent assumptions were misrepresentations of fundamental aspects of science: for example, that a hypothesis functions as a guess about an outcome, but is not necessarily part of a larger explanatory system; that background knowledge may be used to provide ideas about what to study, but this knowledge is not in the form of a theory or other model; and that theory is an optional tool one might use at the end of a study to help explain results. These ideas appear consistent with a “folk theory” of doing science that is promoted subtly, but pervasively, in textbooks, through the media, and by members of the science education community themselves. Finally, although all participants held degrees in science, the participants who eventually used inquiry in their own classrooms were those who had significant research experiences in careers or postsecondary study and greater science‐content background. © 2004 Wiley Periodicals, Inc.

Anatomical sciences: A foundation for a solid learning experience in dental technology and dental prosthetics          下载免费PDF全文

Mahmoud M. Bakr  C. Mark Thompson  Magdalena Massadiq 《Anatomical sciences education》2017,10(4):395-404

Basic science courses are extremely important as a foundation for scaffolding knowledge and then applying it in future courses, clinical situations as well as in a professional career. Anatomical sciences, which include tooth morphology, oral histology, oral embryology, and head and neck anatomy form a core part of the preclinical courses in dental technology programs. In this article, the importance and relevance of anatomical sciences to dental personnel with no direct contact with patients (dental technicians) and limited discipline related contact with patients (dental prosthetists) is highlighted. Some light is shed on the role of anatomical sciences in the pedagogical framework and its significance in the educational process and interprofessional learning of dental technicians and prosthetists using oral biology as an example in the dental curriculum. To conclude, anatomical sciences allow dental technicians and prosthetists to a gain a better insight of how tissues function, leading to a better understanding of diagnosis, comprehensive treatment planning and referrals if needed. Patient communication and satisfaction also increases as a result of this deep understanding of oral tissues. Anatomical sciences bridge the gap between basic science, preclinical, and clinical courses, which leads to a holistic approach in patient management. Finally, treatment outcomes are positively affected due to the appreciation of the macro and micro structure of oral tissues.

Learning style preferences: Vocational students and teachers     

R. T. Pithers  M. Mason 《The Australian Educational Researcher》1992,19(2):61-71

This study investigates, using the Learning Style Questionnaire, the learning style preferences of a group of vocational tertiary students and their teachers. It seeks to identify learning style differences, if any, between students in various stages of their course, between sexes and between “high” and “low” achieving students and their teachers. Furthermore, it examines the similarities and differences between the preferred learning style of the chosen sample of students and other tertiary vocational students. The major findings for the students, relevant to the above variables, and the teachers are discussed. As well, with respect to teachers and students, the implications of attempting to match teaching and learning styles are examined.  相似文献   

Students’ perspectives of early assessment tasks in their first-year at university     

Theda Thomas  Diane Jacobs  Laurine Hurley  Jenny Martin  Svetlana Maslyuk  Mark Lyall 《Assessment & Evaluation in Higher Education》2019,44(3):398-414

Assessment plays an important role in first-year students’ transition to university, influencing how they learn. Poorly designed assessment can be demotivating and may even cause students to withdraw from university. An early low-stakes assessment task is recommended in first year, to provide information to students and staff on student progress, provide students with a positive experience and help them prepare for future assessments. This paper reports on first-year students’ experiences of two different early assessment tasks for two disciplines, one using an online quiz and the other a ‘research challenge’ that served as a precursor to writing an essay. The paper also presents lecturers’ reflections on what they learned, what they would change and the implications for others planning early assessment tasks for first years. Finally, ideas for future research are provided.  相似文献
