基于高校少数民族学生化学课程的教学改革——微格教学法的探索与实践

以塔里木大学少数民族学生为研究对象,结合高校少数民族学生化学课程的教学特点,以提高教师对学生化学课程的教学能力和学生对化学课程的学习能力为目的,本文探索并实践了少数民族学生化学课程的微格教学过程,通过教师微格教学法培训、课堂微型化教学、化学社会化教学、实践灵活化教学以及评价多样化五个环节的具体实施,结果表明,针对少数民族学生的微格教学法是一种可行而有效的教学方法,可以极大地提高教师的教学能力和学生的学习能力。     

The Diverse Geographies of Studentification: Living Alongside People Not Like Us

Recent discussions of studentification have emphasised the development of exclusive purpose-built student accommodation in city centres, shifting the focus away from Houses in Multiple Occupation (HMO) in established residential neighbourhoods. In this paper we explore the growth of student housing on a former social-rented (council) housing estate, and the social friction that it has created—arguing that the production of student HMO has remained prolific, and is pushing the studentification frontier into outer-city deprived communities. Drawing on empirical evidence from a former social-rented housing estate, we explore the recent emergence of a ‘student area’ where student occupation is having marked impacts on a relatively deprived local population. These findings have implications for urban policy making, given they highlight the negative outcomes of studentification in deprived communities, and reveal the challenge this poses for providing affordable housing, and engendering sustainable communities in university towns.     

Effect of classroom air quality on students' concentration: results of a cluster-randomized cross-over experimental study

Abstract To assess the effect of indoor air quality as indicated by the median carbon dioxide (CO(2) ) level in the classroom on the concentration performance (CP) of students, a cross-over cluster-randomized experimental study was conducted in 20 classrooms with mechanical ventilation systems. Test conditions 'worse' (median CO(2) level on average 2115?ppm) and 'better' (median CO(2) level on average 1045?ppm) were established by the regulation of the mechanical ventilation system on two days in one week each in every classroom. Concentration performance was quantified in students of grade three and four by the use of the d2-test and its primary parameter 'CP' and secondary parameters 'total number of characters processed' (TN) and 'total number of errors' (TE). 2366 d2-tests from 417 students could be used in analysis. In hierarchical linear regression accounting for repeated measurements, no significant effect of the experimental condition on CP or TN could be observed. However, TE was increased significantly by 1.65 (95% confidence interval 0.42-2.87) in 'worse' compared to 'better' condition. Thus, low air quality in classrooms as indicated by increased CO(2) levels does not reduce overall short-term CP in students, but appears to increase the error rate. PRACTICAL IMPLICATIONS: This study could not confirm that low air quality in classrooms as indicated by increased CO(2) levels reduces short-term concentration performance (CP) in students; however, it appears to affect processing accuracy negatively. To ensure a high level of accuracy, good air quality characterized, for example, by low CO(2) concentration should be maintained in classrooms.     

中国6城市学生午餐供餐单位卫生状况调查研究

目的 了解我国6城市学生午餐供餐单位的卫生状况。方法按照典型调查的原则抽取我国6城市9家供餐企业和18家学生食堂,采用问卷调查法和现场观察法进行调查。结果供餐企业的卫生问题主要集中在分餐问设施不全、盒饭标识内容不全、运送及留样不符合规定,食堂的卫生问题主要为功能间设计布局不合理、采购食品未按要求索证、服务人员卫生意识差、留样不合规定及卫生管理组织制度不健全。结论应针对企业和食堂存在的问题采取相应改进措施,加强监督和指孚,强化管理,企业推行HACCP。     

Is digital divide an issue for students with learning disabilities?

The purpose of this study was to examine if digital divide exists between elementary school aged children with learning disabilities (LD) and their nondisabled peers in Taiwan. A self-reported questionnaire regarding information and communication technology (ICT) access and ICT competency, Scale of Digital Participation of Elementary School Students, designed by the authors, was used to collect data. Totally, 117 students with LD and 117 peers without disabilities were recruited in this investigation and were conducted with the questionnaire. The results indicated that there was no significant difference in the opportunities to access computers and the Internet at home and at school between children with and without LD. However, there was a significant difference found in ICT competencies between children with and without LD. Moreover, students without LD enhanced their computer competency gradually year by year, but students with LD eventually did not. The findings of this study supported the notion that mere provision of ICT access is not sufficient for children with LD to master ICT skills. A specific designed ICT instruction programs should be provided to children with LD. Finally, suggestions for future studies were also discussed.

本文分析了上海大学生网店创业的现状,发现上海大学生开设网店的主要问题,并给予相应的建议及帮助。要使网店创业真正成为一条大学生的全新创业之路,需要学校、政府的重视和共同努力,也需要广大学生们实践中不断积累和总结经验。在大学校园里,在校生应该多多尝试各种各样的生活与学习方式,找到一条最适合自己的道路,并坚定不移地走下去,才是理智与科学的。     

The identification,implementation, and evaluation of critical user interface design features of computer-assisted instruction programs in mathematics for students with learning disabilities

Critical user interface design features of computer-assisted instruction programs in mathematics for students with learning disabilities and corresponding implementation guidelines were identified in this study. Based on the identified features and guidelines, a multimedia computer-assisted instruction program, ‘Math Explorer’, which delivers addition and subtraction word problem-solving instruction for students with learning disabilities at the early elementary level, was designed and developed. Lastly, usability testing was conducted to assess whether Math Explorer was well-designed in terms of the interface for students with learning disabilities. Given the results of the usability testing, this study corroborated the fact that the critical user interface design features and guidelines in mathematics computer-assisted instruction programs would be essential for facilitating the mathematical learning of students with learning disabilities. Implications for practice and future research were discussed.

Studying a Niche Market: UK Students and the Private Rented Sector

Renting privately is a minority tenure in the UK, but the sector is recognised as being essential to the smooth operation of the wider housing market. The need to target policy effectively has led to an increasing stress on the importance of understanding how local private rental markets operate. Using a number of local case study areas from throughout the country, this paper explores the nature of demand for private rented housing from students. This niche market is a substantial and growing feature of the private rented sector. The paper demonstrates that although student demand shares a number of common characteristics throughout the UK, its localised impacts can vary. Both qualitative and quantitative methods are required to gain an understanding of how student demand affects all aspects of the local housing market, and it is concluded that greater attention needs to be paid to exploring ways of understanding the dynamics of rental market development.
