Organosilane deposition for microfluidic applications

Treatment of surfaces to change the interaction of fluids with them is a critical step in constructing useful microfluidics devices, especially those used in biological applications. Silanization, the generic term applied to the formation of organosilane monolayers on substrates, is both widely reported in the literature and troublesome in actual application for the uninitiated. These monolayers can be subsequently modified to produce a surface of a specific functionality. Here various organosilane deposition protocols and some application notes are provided as a basis for the novice reader to construct their own silanization procedures, and as a practical resource to a broader range of techniques even for the experienced user.     

Effects of social persuasion from parents and teachers on Chinese students’ self-efficacy: an exploratory study

This study compared the effects of social persuasion from parents and teachers on students’ self-efficacy in reading comprehension in English as a foreign language. Ninety-nine Grade 8 Chinese students in a secondary school in Hong Kong completed a questionnaire with six scenarios which tapped their self-efficacy after receiving positive and negative feedback that were described as coming from their teacher, mother and father. Students decreased their self-efficacy after receiving negative feedback and the source of feedback did not make a statistically significant difference. Conversely, positive feedback led to an increase in self-efficacy with the mother’s positive feedback leading to a higher increase in self-efficacy than feedback from the teacher and the father. No statistically significant difference was noted in the change in self-efficacy after receiving feedback from the father and the teacher. Parents and teachers should increase the use of positive feedback and decrease that of negative feedback. Implications for collaboration between teachers and parents in providing positive feedback on students’ academic performance were discussed.     

Children's views on child abuse and neglect: findings from an exploratory study with Chinese children in Hong Kong

Objectives

This research study explored children's views on issues about child abuse in Hong Kong and examined their implications on child protection work and research in Chinese societies.

Method

Six primary schools were recruited from different districts of Hong Kong. Five vignettes of child maltreatment in the form of flash movies were presented to 87 children in 12 focus groups for discussion. The process was video-taped and the data were transcribed verbatim for data analysis by NUDIST.

Results

(1) Children do not have a homogeneous view on issues about child abuse and neglect, and their awareness and sensitivity to different kinds of child abuse are also different; (2) some of their views on child abuse and neglect are uniquely their own and are markedly different from those of adults; (3) some of the views expressed by children, however, are very much akin to those of adults, such as the factors they would consider in deciding whether a case is child abuse or not; (4) children's disclosure of abuse in Hong Kong is often affected by the Chinese culture in which they live, like filial piety and loyalty to parents.

Conclusion

Children's views on issues of child abuse and neglect, no matter they are the same or different from those of adults, serve to inform and improve child protection work. Children are not only victims in need of protection. They are also valuable partners with whom adult practitioners should closely work.

Practice implications

Children have, and are able to give, views on child abuse. They should be listened to in any child protection work no matter their views are same with or different from those of adults. As this study suggests, the relatively low sensitivity of the children to child neglect and sexual abuse, and their reluctance to disclose abuse and neglect due to their loyalty to parents are areas to focus on in preventive child protection work in a Chinese society like Hong Kong.     

Two portfolio systems: EFL students’ perceptions of writing ability,text improvement,and feedback

Research into portfolio assessment (‘PA’) typically describes teachers’ development and implementation of different portfolio models in their respective teaching contexts, however, not much attention is paid to student perceptions of the portfolio approach or its impact on the learning of writing. To this end, this study aims to investigate how two groups of Hong Kong EFL pre-university students (Groups A and B) perceived and responded to two portfolio systems (with each group experiencing one portfolio system either working portfolio or showcase portfolio) in one academic writing course. The case study approach was adopted and data sources included semi-structured interviews, student reflective journals, classroom observations, and analysis of text revisions. Findings indicated that students from the showcase portfolio group (Group B) were less enthusiastic about the effectiveness of PA, and queried whether it could promote autonomy in writing, while the working portfolio group (Group A) was more receptive to the experience, and considered that a feedback-rich environment in the working portfolio system could facilitate writing improvement. The paper concludes with a discussion of how PA can be used to promote self-regulation in the learning of writing.     

Hong Kong-based TEFL/TESOL global academics: life,culture, mobility,globalisation and cosmopolitanism

This paper is about a qualitative research concerning a group of expatriates' (TEFL/TESOL English language teachers) experiences in Hong Kong. Data related to their life, attitudes and cultural dispositions are discussed under four different states, namely, Adaptation, Drifting in Global Comfort, Drifting in Global Discomfort and Bitter/Sweet Home. Together, these contribute to their mobility pattern – the Global Drift. The study discusses their global experiences and situations relating to the interplay of personal choice on the one hand and changing global and local processes and conditions on the other. It is argued that this is a self-perpetuating group sustained and reproduced by a Global Quality including distinct cultural dispositions, concepts of home and the reproduction of third-culture-kids, who are tailor-made for twenty-first-century mobile work. Finally, the research is situated in the study of cosmopolitanism, particularly in the identification of cosmopolitans and their dispositions. Alternative ways of theorising home (as interactive continuums) and issues related to mobility and dispositions will be discussed briefly.     

Conceptions of Teaching Art Held by Secondary School Art Teachers

Research into teachers' conceptions of teaching can be justified in that deep seated beliefs impact upon the way teachers teach and influence the learning approaches of their students. This study examined conceptions of teaching art, through interviews with 18 secondary school art teachers in Hong Kong. The analysis resulted in a two‐level characterisation of conceptions under broad essentialist and contextualist orientations. There were four subordinate conception categories, namely moral development in art and aesthetic development in art under the essentialist orientation, and intellectual development through art, and expression and therapy through art as sub‐categories of the contextualist orientation. The categories were defined and delimited by six dimensions. The categories were seen as clearly distinguishable but related, though not hierarchically. There was no evidence of the category scheme being culturally specific, as the majority of the teachers held beliefs which were not consistent with the traditional manner of Chinese painting.     

Visuomotor integration and executive functioning are uniquely linked to Chinese word reading and writing in kindergarten children

This cross-sectional study examined the associations of visuomotor integration and executive functioning with Chinese word reading and writing in kindergarten children. A total of 369 Chinese children (mean age = 57.99 months; 55% of them were girls) from Hong Kong, China, completed tasks on visuomotor integration, executive functioning, and Chinese word reading and writing. Children also completed tasks on rapid automatized naming, and their mothers provided child and family background information. Hierarchical regression analyses revealed that, controlling for child age, gender, and rapid automatized naming and maternal education, both visuomotor integration and executive functioning were uniquely linked to Chinese word reading and writing. Findings highlighted the importance of visuomotor integration and executive functioning in understanding the development of Chinese word reading and writing in early years, and the utility of targeting visuomotor integration and executive functioning to help kindergarten children to learn to read and write in Chinese.

Enacting feedback utilization from a task-specific perspective

Feedback is central to successful teaching and learning. Despite extensive research on the relationship between feedback, pedagogy and learning, there remain no conclusive answers as to how feedback can be effectively utilized by learners. Recently, there is emerging research exploring how feedback is conceptualized as dialogic processes to facilitate provision and uptake of feedback; and how feedback utilization is best supported by learner active involvement in the iterative feedback process for future learning. Drawn from this knowledge base, this article aims to review four aspects of feedback scholarship including nature, paradigms, issues and trends which serve as a theoretical basis, together with instructors’ interviews, to inform how five common assessment tasks in one social sciences faculty could be strategically revamped to promote feedback utilization. The article concludes with pedagogical insights to suggest three conditions wherein feedback could be made sustainable to support learning through a redesigning of conventional assessment tasks in the higher education contexts.
