Student perception of assessment practices: towards ‘no loser’ classrooms for all students in the ethnic minority schools in Hong Kong

As part of a wide-scale education reform, Hong Kong schools have been focusing on the creation of ‘no loser’ classrooms that support learning for all students (Education Commission 2000). This article examined both groups of ethnic minority and Chinese students’ perception of assessment practices and the extent to which classroom practice is consistent with preferred assessment practices. The 11 items of assessment practices list, developed by Brown et al. (2009a), were used to investigate the perceptions of 1,518 student respondents from 15 primary and secondary schools, in which a large number of ethnic minority students were accommodated. A confirmatory factor analysis showed that the respondents in the group from secondary schools viewed teacher-dominated assessment as the most important assessment practice in the model examined (Brown et al. Learning and Instruction, 19(2), 97–111, 2009b) whereas those in the primary group considered teacher-student interactive assessment as the most important practice. Also, three perceptions of assessment practices of ethnic minority students were confirmed: teacher-dominated, student-centred and teacher-student interactive. Amongst them, the most preferred one was the teacher-student interaction assessment practice. Finally, the implications of the creation of a no loser classroom for all students are discussed.     

Leptotrichia hongkongensis sp. nov., a novel Leptotrichia species with the oral cavity as its natural reservoir

A straight, non-sporulating, Gram-variable bacillus (HKU24T) was recovered from the blood culture of a patient with metastatic breast carcinoma. After repeated subculturing in BACTEC Plus Anaerobic/F blood culture broth, HKU24T grew on brucella agar as non-hemolytic, pinpoint colonies after 96 h of incubation at 37 °C in an anaerobic environment and aerobic environment with 5% CO2. Growth was enhanced with a streak of Staphylococcus aureus. HKU24T was non-motile and catalase-negative, but positive for alkaline phosphatase, β-glucosidase, and α-glucosidase. It hydrolyzed phenylphosphonate and reduced resazurin. 16S rRNA, groEL, gyrB, recA, and rpoB sequencing showed that HKU24T occupies a distinct phylogenetic position among the Leptotrichia species, being most closely related to Leptotrichia trevisanii. Using HKU24T groEL, gyrB, recA, and rpoB gene-specific primers, fragments of these genes were amplified from one of 20 oral specimens. Based on phenotypic and genotypic characteristics, we propose a new species, Leptotrichia hongkongensis sp. nov., to describe this bacterium.     

支持开放教育资源项目的方法

本文考察了英国教育技术互用性标准中心（CETIS）通过支持国家项目（即英国联合信息系统委员会（JISC）和高等教育委员会的英国开放教育资源试点项目,详见http：／／www．jisc．ae．uk／oer）,以促进发布开放教育资源方面的经验,并探索了如何让我们的支持模式对其他相关项目有所启发,并能改编用于鼓励开放课件运动的可持续性技术支持网络。作为一个涵盖英国众多大学的国家层面的创新举措,众多开放教育资源提供者参与了英国开放教育资源（UKOER）,这包括个别教育者、学科联合体和机构。考虑到这种多样性,从一开始我们就意识到没有任何一种技术解决方案能适合所有的项目。因此,也没有委托专门的工具、描述性标准、交流或分发机制（除要求所有制作的资源应该放在国家学习资源库中外,详见http：／／jorum．ae．uk）。为了支持这一项目,我们引导采取不同的方法和形成不同的社群,也许在支持发布开放教育资源方面,任何类似的跨机构创新都将会面临相似的问题。我们的项目支持方法已从具体的细节问题发展到提供基本的支持原则,从而预测其他问题,并推动最佳实践。我们的做法是：通过会议上的技术汇报和讨论机会,以及在博客上发帖,激发讨论;通过技术评论讨论,并记录针对这些公布在网上的讨论的总结性内容,从而调查个别项目的技术选择;针对通过以上方式所发现的问题,以及项目博客上凸显的问题,做出相应的反馈。考虑到如何使这一方法在更广泛的范围内应用,我们也反思了这种公开的工作模式所面临的挑战、这一方法的开支、适应性,以及我们所认为的其在支持开放教育资源管理和传播方面所扮演的角色。     

Foot strike patterns and ground contact times during high-calibre middle-distance races

Abstract The aims of this study were to examine ground contact characteristics, their relationship with race performance, and the time course of any changes in ground contact time during competitive 800?m and 1500?m races. Twenty-two seeded, single-sex middle-distance races totalling 181 runners were filmed at a competitive athletics meeting. Races were filmed at 100?Hz. Ground contact time was recorded one step for each athlete, on each lap of their race. Forefoot and midfoot strikers had significantly shorter ground contact times than heel strikers. Forefoot and midfoot strikers had significantly faster average race speed than heel strikers. There were strong large correlations between ground contact time and average race speed for the women's events and men's 1500?m (r?=?-0.521 to -0.623; P?相似文献   

The Gender Mix Among Staff in Schools for Pupils with Severe and Profound and Multiple Learning Difficulties and its Impact

Phil Goss has extensive experience as a practitioner and manager in schools for pupils with severe and profound and multiple learning difficulties. In this article, he reports on his enquiries into the gender mix among staff in these schools. He finds that there are significantly more women than men working as teachers and in support roles in these specialist contexts. Phil Goss goes on to discuss the outcomes of his research into headteachers' perceptions of the impact of this gender imbalance. In concluding, he makes a series of proposals for future policy on recruitment and staff development, for teachers and teaching assistants. Phil Goss argues that we need to find ways to bring more men into this work.
