Parent–Teacher Conferences in a Secondary School: A Case Study     

Paul Leung 《Pastoral Care in Education》2001,19(1):28-30

The authors report on the findings of a case study of parent–teacher conferences in a secondary school in Hong Kong. They explored through interviews parents' and teachers' perspectives of parent–teacher conferences. They noted that parent–teacher conferences were sources of stress for teachers and embarrassment for parents. Parent–teacher conferences were useful for problem‐clarification. The building of mutual trust was the most important conferencing skill. They drew out some practical guidelines which were useful to teachers of the case study school but are also valuable to all teachers who wish to work effectively and positively with parents.  相似文献   

Construction and Validation of a Chinese Value of Learning Scale (CVLS)     

Angela Leung  Iris Chi  Nelson Chow  Kin Sun Chan  Kee Lee Chou 《Educational gerontology》2013,39(10):907-920

The Chinese Value of Learning Scale (CVLS) is a 5-item instrument for assessing the value of learning in Chinese culture. The psychometric properties of CVLS were investigated in a convenient sample of 583 Chinese soon-to-be-aged adults in Hong Kong. CVLS possesses high internal consistency and exhibited satisfactory short-term test-retest reliability. CVLS also exhibited high face validity and mild convergent validity with other 48-item openness-to-experience scale (OTES) from Revised NEO Personality Inventory, and is significantly related to the past and actual learning experience. In view of its brevity and easy administration, CVLS offers a useful instrument to further investigate the value of learning in Chinese culture and its possible relationship with adults' learning behaviour.  相似文献   

Chinese Retirees' Learning Interests: A Qualitative Analysis     

Angela Leung  Iris Chi  Vico Chiang 《Educational gerontology》2013,39(12):1105-1121

This paper reports the results of two semistructured focus group interviews with 17 retirees that explore the issues these retirees perceived as central to their learning in later life (LLL). Focus is especially placed on the factors leading to their learning interests after retirement. A total of six themes (past experience in adulthood and voluntary work, perception of learning, social support, living alone, self-efficacy, and openness) were identified to be related to learning interest in later life. This study has implications for future research and service planning of LLL in the Chinese population.  相似文献   

The Roles of Hong Kong Preservice Early Childhood Teachers’ Creativity and Zest in Their Self-efficacy in Creating Child-centered Learning Environments     

Sum Kwing Cheung  Ricci Wai-tsz Fong  Suzannie Kit Ying Leung  Elsa Ka-wei Ling 《Early education and development》2013,24(6):788-799

Research Findings: This study investigated the relationships of preservice teachers’ year of study in the teacher education program, creativity, zest, and self-efficacy in managing children’s behaviors to self-efficacy in creating child-centered learning environments. Data were collected from 275 Hong Kong preservice teachers via self-reported questionnaires. Results showed that creativity had a direct positive linkage with self-efficacy in creating child-centered learning environments. Zest was associated with self-efficacy in creating child-centered learning environments, however, indirectly through self-efficacy in managing children’s behaviors. Year of study was unrelated to both self-efficacies. Practice or Policy: Preservice teachers’ creativity and zest can be conceptualized as personal resources for creating child-centered environments. Teacher education programs should therefore incorporate components of fostering pre-service teachers’ own creativity and zest.  相似文献   

Social preference choices in late elementary school: Within and across group nominations     

Thomas W. Farmer  Man‐Chi Leung  Kristen Keagy  Daniel J. Boudah  Patrick Akos  Erin McDonough  Cristin M. Hall 《Psychology in the schools》2009,46(4):362-374

This study examined the social preference nominations (i.e., “liked most” and “liked least”) in relation to peer group and classroom social dynamics in a sample of 622 fifth graders from 11 schools in a southeastern state. Liked most and liked least nominations were given to a small concentration of students within classrooms. The top five nominees for liked most and liked least tended to be in peer groups and associated with at least one classmate who shared their position as a top nominee. The majority of liked most nominations in a classroom were made toward members inside the nominator's group, whereas the majority of liked least nominations were made toward peers outside one's group. Students in the same peer group were more likely to nominate the same peers as liked most than were students who did not affiliate together. In contrast, the concordance for liked least nominations was moderate at both the peer‐group and classroom level. Implications for school‐based social interventions are discussed. © 2009 Wiley Periodicals, Inc.  相似文献

SLIPS-TENG: robust triboelectric nanogenerator with optical and charge transparency using a slippery interface     

Wanghuai Xu  Xiaofeng Zhou  Chonglei Hao  Huanxi Zheng  Yuan Liu  Xiantong Yan  Zhengbao Yang  Michael Leung  Xiao Cheng Zeng  Ronald X Xu  Zuankai Wang 《国家科学评论(英文版)》2019,6(3):540

Energy harvesting devices that prosper in harsh environments are highly demanded in a wide range of applications ranging from wearable and biomedical devices to self-powered and intelligent systems. Particularly, over the past several years, the innovation of triboelectric nanogenerators (TENGs) that efficiently convert ambient kinetic energy of water droplets or wave power to electricity has received growing attention. One of the main bottlenecks for the practical implications of such devices originates from the fast degradation of the physiochemical properties of interfacial materials under harsh environments. To overcome these challenges, here we report the design of a novel slippery lubricant-impregnated porous surface (SLIPS) based TENG, referred to as SLIPS-TENG, which exhibits many distinctive advantages over conventional design including optical transparency, configurability, self-cleaning, flexibility, and power generation stability, in a wide range of working environments. Unexpectedly, the slippery and configurable lubricant layer not only serves as a unique substrate for liquid/droplet transport and optical transmission, but also for efficient charge transfer. Moreover, we show that there exists a critical thickness in the liquid layer, below which the triboelectric effect is almost identical to that without the presence of such a liquid film. Such an intriguing charge transparency behavior is reminiscent of the wetting transparency and van der Waals potential transparency of graphene previously reported, though the fundamental mechanism remains to be elucidated. We envision that the marriage of these two seemingly totally different arenas (SLIPS and TENG) provides a paradigm shift in the design of robust and versatile energy devices that can be used as a clean and longer-lifetime alternative in various working environments.  相似文献   

Agar-polydimethylsiloxane devices for quantitative investigation of oviposition behaviour of adult Drosophila melanogaster     

Jacob C. K. Leung  Rhodri W. Taylor-Kamall  Arthur J. Hilliker  Pouya Rezai 《Biomicrofluidics》2015,9(3)

Drosophila melanogaster (fruit fly) is a model organism and its behaviours including oviposition (egg-laying) on agar substrates have been widely used for assessment of a variety of biological processes in flies. Physical and chemical properties of the substrate are the dominant factors affecting Drosophila''s oviposition, but they have not been investigated precisely and parametrically with the existing manual approaches. As a result, many behavioral questions about Drosophila oviposition, such as the combined effects of the aforementioned substrate properties (e.g., exposure area, sugar content, and stiffness) on oviposition and viability, and their threshold values, are yet to be answered. In this paper, we have devised a simple, easily implementable, and novel methodology that allows for modification of physical and chemical composition of agar substrates in order to quantitatively study survival and oviposition of adult fruit flies in an accurate and repeatable manner. Agar substrates have been modified by surface patterning using single and hexagonally arrayed through-hole polydimethylsiloxane (PDMS) membranes with various diameters and interspacing, as well as by substrate stiffness and sugar content modification via alteration of chemical components. While pure PDMS substrates showed a significant lethal effect on flies, a 0.5 mm diameter through-hole access to agar was found to abruptly increase the survival of adult flies to more than 93%. Flies avoided ovipositing on pure PDMS and on top of substrates with 0.5 mm diameter agar exposure areas. At a hole diameter of 2 mm (i.e., 0.25% exposure area) or larger, eggs were observed to be laid predominately inside the through-holes and along the edges of the PDMS-agar interface, showing a trending increase in site selection with 4 mm (i.e., 1% exposure area threshold) demonstrating natural oviposition rates similar to pure agar. The surface-modified agar-PDMS hybrid devices and the threshold values reported for the substrate physical and chemical conditions affecting oviposition are novel; therefore, we advocate their use for future in-depth studies of oviposition behaviour in Drosophila melanogaster with accuracy and repeatability. The technique is also useful for development of novel assays for learning and decision-making studies as well as miniaturized devices for self-assembly of eggs and embryonic developmental investigations.  相似文献
