Rapid and cost-effective fabrication of selectively permeable calcium-alginate microfluidic device using ��modified�� embedded template method

In this paper, we have presented a non-lithographic embedded template method for rapid and cost-effective fabrication of a selectively permeable calcium-alginate (Ca-alginate) based microfluidic device with long serpentine delay channel. To demonstrate the versatility of the presented method, we have demonstrated two different strategies to fabricate serpentine long delay channels without using any sophisticated microfabrication techniques, in formal lab atmosphere. The procedure presented here, also, enables the preparation of a multilayered microfluidic device with channels of varying dimensions, in a single device without using any sophisticated micromachining instrumentation. In addition, we have also qualitatively studied the diffusion of small and large molecules from a Ca-alginate based microfluidic device and proposed a method to effectively control the out-flow of macro biomolecules from the crosslinked Ca-alginate matrix to create a selectively permeable matrix required for various biological and biomimetic applications, as mentioned in the Introduction section of this work.     

Assessing the quality and equality of Hong Kong basic education results from PISA 2000+ to PISA 2006

This paper seeks to examine the quality and equality of basic education of Hong Kong based on the first three cycles of the Program for International Student Assessment (PISA). Results from these three assessments suggested that the Hong Kong students have an outstanding performance in mathematics, science and reading. In particular, the performance of reading improves substantially in PISA 2006. As far as equality in education is concerned, the achievement gap of students from different socio-economic backgrounds in Hong Kong is relatively small compared with other countries. However, the academic performance variation between-schools suggest that, there is still academic segregation among secondary schools in Hong Kong although it has been reduced slightly in the PISA 2006.     

Meeting the highly qualified teachers challenge

The moulding of the future of a nation depends on the teachers and the education they provide in schools. Research evidence from the US. National Assessment of Educational Progress (NAEP) confirms this to be the case. Quantitative analysis of data indicates that measures associated with pre-service teacher preparation are by far the strongest correlates of student achievement (Darling-Hammond 2000). The research report of Wilson, Floden, and Ferrini-Mundy (2001) also suggests a strong relationship between teacher preparation and teacher effectiveness. Other research studies similarly indicate that differences in teacher quality are the most crucial for student achievement when compared with variables such as class size, streaming, or the amount of homework (Anderson & Helms 2001; Mendro 1998; Powell & Anderson 2002; Rivkin, Hanushek & Kain 2001; Saunders & Horn 1994; Strong & Tucker 2000) as possible contributory factors. In the pursuit of improved student achievement, we therefore need to examine seriously the role of teacher variables, ranging from teacher qualifications and their subject matter knowledge, to what motivates them to take up teaching as a career and as a consequence, how they teach in classrooms.     

Social networking and Web 2.0 in information literacy

This paper discusses free online and Internet tools that can be adapted by librarians for use with library instruction and information literacy training, with a focus on social media and Web 2.0 technologies, including social networking websites Facebook and Twitter, blogs, RSS, wikis, and video sharing. Many students already use these technologies and are readily engaged with the library when the technologies are incorporated into library websites and classes. There are challenges in using these technologies, especially in countries with oppressive governments. This paper is based, in part, on a presentation the authors gave at the UNESCO Training the Trainers in Information Literacy Workshop at the Bibliotheca Alexandrina in Alexandria, Egypt in November 2008.     

Non-traditional students in tertiary education: inter-disciplinary collaboration in curriculum and pedagogy in community services education in Australia

Education policy in Australia has accelerated its aim to increase participation of under-represented groups in tertiary education including students who are culturally and linguistically diverse and have low socio-economic status. These students generally have not had prior access to privileged academic discourse, which can further disadvantage them in their participation and progress in tertiary education. In this article, we outline a cross-discipline curriculum initiative and pedagogy that draws on critical literacy and the metaphor of discourse community to integrate language and academic skills into community services qualifications. We argue that this – supports the genuine participation of under-represented (non-traditional) students. It aspires to not only support students’ entry into the new academic terrain, but to enable students to adopt a critical stance to the discourses in which they are learning to participate. This we argue is crucial, when expertise is not just a way of meeting its ostensible purposes, but is also a way of exercising power. Although we report on the application of this initiative to entry level curricula (Diploma), we suggest that it has relevance and application to Bachelor levels in a range of disciplines, both in supporting pedagogy and for transition to Bachelor level study.     

Pursuing justice for refugee students: addressing issues of cultural (mis)recognition

In this paper Nancy Fraser’s conceptual tools are drawn on to theorise issues of justice in a culturally diverse primary school in Australia where approximately 30% of the student population are immigrant/refugees. The paper examines justice issues of cultural recognition in relation to refugee student identity, behaviour and assessment. Drawing on interview data from a study that sought to identify productive approaches to addressing equity for refugee students, the paper highlights the school’s efforts to remedy issues of cultural misrecognition associated with an equation of refugee student difference and marginality with deficit and lack. Such efforts relate to the school’s endeavours to create an inclusive and socially cohesive environment that supports a valuing of, and connection to, refugee student difference. These endeavours are theorised as highly productive in their capacity to disrupt the relations of cultural domination, non-recognition and disrespect that exclude and/or malign some refugee students at the school and broader level. The paper argues the importance of such an approach in light of the unprecedented diversity and complexity of the global context where schools are consistently challenged with new and changing equity concerns and priorities.     

Social and emotional learning in the classroom: promoting mental health and academic success

Numerous studies conducted in different countries have focused on empirical research and literature reviews on prevalence, consequences, and strategies relative to cyberbullying; however, there is a lack of research regarding cyberbullying from a cross-cultural perspective. This article reviews recent research on cyberbullying and presents information on prevention and intervention from an international perspective.     

The Things Girls Shouldn't See: Relocating the penis in sex education in Hong Kong

This article reports on how young women in Hong Kong relate to the penis. A total of nine focus group interviews were conducted at the University of Hong Kong to enable participants to reflect on and talk about their 'experience of the penis'. It is found that despite society's various attempts to restrict their access to the penis, it is very much present and available to the young women in Hong Kong. While most of the participants reported the normative response of disgust, which was expected as part of the 'proper femininity', positive experiences of the penis characterised by agency, mastery and fulfilment were also reported. Some of the things they do, such as watching an exhibitionist or actively consuming sexually explicit materials and pornography, subvert the discursive practice of positioning women as passive sexual objects. It is believed that with more open access to knowledge and experience, women will stand a better chance of achieving a more agentive relationship, not only with the penis as a potential transitional object in intimate relationships, but also with their own sexuality.     

Piecing together the puzzle: development of the Societal Attitudes towards Autism (SATA) scale

The rise in the prevalence of autism creates a need for a reliable and valid measure of attitudes towards autism. The current study describes the development of a brief 16‐ item measure of Societal Attitudes towards Autism (SATA) that exhibits sound psychometric properties and has a demonstrated ability to discriminate between expert and general college student samples. The final SATA was the result of pilot work on 75 items and exploratory and confirmatory factor analyses on a 45‐item version with 475 undergraduates. Knowledge and personal distance subscales yielded inconsistent reliability and validity outcomes. The SATA showed strong content and construct validity as evidenced by known groups discrimination, and predicted associations with an attitude towards disability measure, an autism preference item, and a measure of implicit attitudes towards disabilities.     

The purposes outdoor education does,could and should serve in Singapore

This paper discusses the purposes that outdoor education does, could and should serve in Singapore. Gert Biesta’s conceptualisation of three functions of education is adapted to frame deliberations on the purposes of outdoor education in Singapore’s socio-political and educational milieu. The author suggests that outdoor education in Singapore could and should give high priority to serving three educational purposes; namely, building resilience, building emotional bonds with the place that constitutes Singapore, and building ecological literacy. In pursuing such purposes, outdoor education in Singapore might lessen the gap between the educational outcomes it currently produces and those it could achieve in the future.
