Many researchers have stressed that the acoustic environment is crucial to the speech perception, academic performance, attention, and participation of students in classrooms. Classrooms in highly urbanised locations are especially vulnerable to noise, a major influence on the acoustic environment. The purpose of this investigation was to determine noise levels in one such urban environment, Hong Kong. The ambient noise level, and its relationship to the speech intensity levels of both teachers and students was surveyed in 47 primary school classrooms. Moreover, the presence of acoustical treatments for noise reduction and the use of classroom amplification systems were documented for each classroom. The survey found that the mean occupied noise level was 60.74 dB (A); the mean unamplified and amplified speech‐to‐noise ratios of teachers were 13.53 dB and 18.45 dB, respectively; while the mean unamplified speech‐to‐noise ratio for students was 4.13 dB. Most of the classrooms exhibited insufficient acoustical treatments to provide significant noise reduction. The listening environment in many Hong Kong primary schools was not favourable for optimal classroom learning. Recommendations for improving the acoustical environment in classrooms in highly urbanised locations such as Hong Kong are discussed. 相似文献

This Youth Participatory Action Research (YPAR) study represents a collaboration with six students from alternative education to inquire about the experiences of vulnerable youth – students in alternative education and youth who have dropped out of school. Utilizing the Enhanced Critical Incident Technique, youth researchers asked their peers what helped and hindered their retention and success in mainstream and alternative education. Youth researchers engaged in authentic participation and took part in the iterative phases of YPAR – critical reflection and social action. Their involvement empowered them to advocate for their peers by disseminating the results and recommendations to key stakeholders within the community. Youth researchers conducted semi-structured interviews with 18 participants. Overall, the findings show that relationships with staff and peers, flexibility, psychosocial and academic supports, and personal circumstances are vital in helping vulnerable students succeed in school. Engagement in YPAR provided insight into working with vulnerable youth in a manner that promotes agency and social change within educational institutions. 相似文献

The case method is a definitive and foundational technology in business education. It was first developed as a vocational training tool equipping students for future employment. In this conception, the organisation was seen as a machine, and managers as the engineers who would maintain it through planned interventions. The case method allowed aspiring managers to practise intervention skills in a safe environment. Since the origins of the case method in US business schools before the First World War, conceptions of organisations have moved on. They are no longer seen as machine-like, but as complex, ambiguous, and protean. The 'wicked' problems that potential managers will face in an uncertain world require the development of critical thinking and sensemaking abilities. While the traditional approach to the case continues, its use as a vehicle to explore and manage complexity and ambiguity is emerging, although this is facing resistance from some students and staff. 相似文献

The popularity of Jacques Rancière in recent work in educational philosophy has rejuvenated discussion of the merits and weaknesses of Socratic education, both in Plato's dialogues and in invocations of Socrates in contemporary educational practice. In this essay Jordan Fullam explores the implications of this trend through comparing Rancière's educational thought to an analysis of the relationship between dialectic and stultification in Plato's Republic. This task clarifies what is useful in the recent wave of scholarship that brings Rancière's work to bear upon Socratic education, and what we might redeem in the practice of teaching that Plato assigns to the character of Socrates in the Republic. Fullam also draws on the educational literature on Socratic education to provide further context to explore the usefulness of both Rancière and Socrates for contemporary teaching. 相似文献

AbstractThis study investigated the influence of the regression model and initial intensity during an incremental test on the relationship between the lactate threshold estimated by the maximal-deviation method and performance in elite-standard runners. Twenty-three well-trained runners completed a discontinuous incremental running test on a treadmill. Speed started at 9 km · h?1 and increased by 1.5 km · h?1 every 4 min until exhaustion, with a minute of recovery for blood collection. Lactate–speed data were fitted by exponential and polynomial models. The lactate threshold was determined for both models, using all the co-ordinates, excluding the first and excluding the first and second points. The exponential lactate threshold was greater than the polynomial equivalent in any co-ordinate condition (P < 0.001). For both models, the lactate threshold was lower when all co-ordinates were used than when the first and the first and second points were excluded (P < 0.001). 10-km race pace was correlated with both the exponential and polynomial lactate thresholds for all the co-ordinate conditions (r ≥ 0.75, P < 0.001 and r ≥ 0.56, P < 0.05, respectively). The results suggest that the exponential lactate threshold should be used instead of the polynomial equivalent since it is more strongly associated with performance and is independent of the initial intensity of the test. 相似文献

Fungi are non-chlorophyllus microorganisms, which constitutes the main source of outdoor and indoor allergens. The antigens present in the spores and fragments of hyphae induce allergic responses in sensitized patients. The frequently recognized fungi associated with asthma include Alternaria, Cladosporium, Aspergillus, and Penicillium. With the advent of molecular biology techniques a number of fungal genes encoding relevant allergens have been cloned and the expressed allergens purified and characterized. In this review, we have presented the recent developments, where recombinant allergens have been used in the precise diagnosis of fungal allergy. We have also discussed the role played by these allergens and the T- and B-cell epitopes in the immune mechanism in fungal allergy. 相似文献

IntroductionIt is unclear what is the best strategy for applying patient-based real-time quality control (PBRTQC) algorithm in the presence of multiple instruments. This simulation study compared the error detection capability of applying PBRTQC algorithms for instruments individually and in combination using serum sodium as an example.Materials and methodsFour sets of random serum sodium measurements were generated with differing means and standard deviations to represent four simulated instruments. Moving median with winsorization was selected as the PBRTQC algorithm. The PBRTQC parameters (block size and control limits) were optimized and applied to the four simulated laboratory data sets individually and in combination.ResultsWhen the PBRTQC algorithm were individually optimized and applied to the data of the individual simulated instruments, it was able to detect bias several folds faster than when they were combined. Similarly, the individually applied algorithms had perfect error detection rates across different magnitudes of bias, whereas the error detection rates of the algorithm applied on the combined data missed smaller biases. The performance of the individually applied PBRTQC algorithm performed more consistently among the simulated instruments compared to when the data were combined.DiscussionWhile combining data from different instruments can increase the data stream and hence, increase the speed of error detection, it may widen the control limits and compromising the probability of error detection. The presence of multiple instruments in the data stream may dilute the effect of the error when it only affects a selected instrument. 相似文献

Peer assessment has been gaining significant ground as a means of fostering an environment of accountability and responsibility for group projects in higher education. A popular peer assessment method assigns individual grades via a linear relationship to peer assessment scores. Using this method, a group member who receives his or her group’s average peer assessment score is assigned the instructor‐given group grade; the group member who receives a total peer assessment score of zero is assigned an individual grade of zero. Unfortunately, applying this method often requires time‐consuming exploratory data analysis because of the potential for the method to yield a high spread of grades, including grades over 100%. The present study proposes a modification, which accounts for the degree of student agreement. When the modified procedure results in a change from the group grade, the direction of change is always the same, but with smaller magnitude, requiring less subsequent data analysis and instructor time demands. Easy‐to‐modify SAS code for applying the method is presented in the Appendix. 相似文献
