Adolescence is characterized as a period of social reorientation toward peer relationships, entailing the emergence of sophisticated social abilities. Two studies (Study 1: N = 42, ages 13–17; Study 2: N = 81, ages 13–16) investigated age group differences in the impact of relationship reciprocation within school‐based social networks on an experimental measure of cooperation behavior. Results suggest development between mid‐ and late adolescence in the extent to which reciprocation of social ties predicted resource allocation. With increasing age group, investment decisions increasingly reflected the degree to which peers reciprocated feelings of friendship. This result may reflect social‐cognitive development, which could facilitate the ability to navigate an increasingly complex social world in adolescence and promote positive and enduring relationships into adulthood.  相似文献   

Examining the Rule of Thumb of Not Using Multilevel Modeling: The “Design Effect Smaller Than Two” Rule     

Mark H. C. Lai  Oi-man Kwok 《Journal of Experimental Education》2015,83(3):423-438

Educational researchers commonly use the rule of thumb of “design effect smaller than 2” as the justification of not accounting for the multilevel or clustered structure in their data. The rule, however, has not yet been systematically studied in previous research. In the present study, we generated data from three different models (which differ in the location of the clustering effect). With a 3 (design effect) × 5 (cluster size) × 4 (number of clusters) Monte Carlo simulation study we found that the rule should not be applied when researchers: (a) are interested in the effects of higher-level predictors, or (b) have a cluster size less than 10. Implications of the findings and limitations of the study are discussed.  相似文献   

Utilization of online educational resources in teaching: A moderated mediation perspective     

Su Iong Kio  Meng Chan Virgina Lau 《Education and Information Technologies》2017,22(4):1327-1346

The study builds on a newly modified Technology Acceptance Model (TAM) to substantiate the motivation and operation of teachers’ utilization of online learning resources. A ‘Comprehensiveness’ construct is proposed in the modified TAM to reflect the breadth and depth of rich online knowledge. This new construct serves as the mediator between ‘Usefulness’ and ‘Behavioral Intention’ in the new TAM structure. In addition, the ‘Ease of Use’ factor in conventional TAM is proposed to moderate the mediation in the modified TAM. Survey data are collected from 301 teachers undertaking certified training in Macau and Structural Equation Model (SEM) technique is used to assess the model. Moderated mediation is evaluated using both multi-group bootstrapping method and moderated path analysis method. Both methods verify the presence of moderated mediation with partial mediation in high Ease of Use values and full mediation in low Ease of Use values. Theoretical implication of the current study extends the coverage of TAM applications and academic implication suggests the strengthening in teachers’ professional development and government sponsorship in building repositories of online resources.  相似文献   

The Perfect Marriage? – Language and Art Criticism in the Hong Kong Public Examination Context          下载免费PDF全文

Chung‐yim Lau  Cheung‐on Tam 《The International Journal of Art & Design Education》2017,36(1):61-70

Art education in Hong Kong has undergone various changes in response to educational reform. In art assessment, a major change in the Hong Kong New Senior Secondary (NSS) Curriculum is the inclusion of art criticism as a compulsory component of the new public examination. Assessing students’ abilities to interpret art in an art criticism public examination context is a critical issue in Hong Kong because the new senior secondary curriculum and assessment has brought attention to the role of written language in the art examination paper. This means the examination assesses not only students’ abilities to interpret art, but also their language abilities required to respond to art in written form. Since this new mode of assessment of art criticism has been published a number of issues have appeared. Recent studies show that teachers and students perceive this development negatively and they believe that the written format will assess students’ written language abilities rather than their critical abilities. These findings challenge the justification of the new art assessment policy and raise questions about the role of written language in responding to art. This article aims to raise the issue of the marriage between language and art criticism in the Hong Kong public examination context. It argues and examines the relationship of language to art interpretation, reasoning in the assessment, and issues in the public art criticism examination context. The issues addressed in this article provide opportunities for researchers and policy makers to reconsider and refine the new form of examination.  相似文献

Graphene Based Electrochemical Sensor for the Detection of Volatile Organic Compounds     

Yixin Zhang  Kim KT Lau 《学周刊C版》2014,(36)

Many household consumables contain volatile organic compounds(VOCs)as the active ingredient.Long term exposure to VOCs could cause various health problems,especially to the respiratory system.Graphene has attracted a lot of attention recently for its potential to be used as sensing material for VOCs.In this project we have constructed graphene/PVA composite based gas sensors for VOC detection.It was perceived that the polymer could introduce better selectivity to the sensor.Results suggest that the proposed sensor is highly sensitive to low molecular weight VOCs and that the manner in which the sensor respond to the vapour depends on the polarity or hydrophobicity of the vapour.  相似文献   

Collaborating with front-line teachers to incorporate self-regulated learning in Chinese language classes     

Kit-ling Lau 《Educational Research and Evaluation》2013,19(1):47-66

This study aimed to initially explore the possibility of helping front-line teachers to integrate the principles of self-regulated learning (SRL) into Chinese reading instruction in a 1-year collaborative project. A total of 197 Secondary 3 students and 6 Chinese language teachers from a secondary school in Hong Kong participated in the study. The findings of quantitative and qualitative data in this study generally support the feasibility of incorporating the elements of SRL in Chinese reading instruction. Students improved their comprehension performance, intrinsic motivation, strategic knowledge, and strategy use after this learning experience. Teachers also expressed positive attitudes towards the new instruction and made constructive changes on the instructional materials and activities. However, the study found teachers' traditional beliefs might affect theimplementation of SRL instruction. The implications of these findings for understanding Chinese students' capacity for SRL and planning effective reading instruction to enhance their SRL abilities are discussed.  相似文献   

The roles of teacher efficacy in instructional innovation: its predictive relations to constructivist and didactic instruction     

Youyan Nie  Gim Hoon Tan  Albert Kienfie Liau  Shun Lau  Bee Leng Chua 《Educational Research for Policy and Practice》2013,12(1):67-77

Constructivist instruction has been implemented in the current instructional innovation in Singapore. Large scale survey study was conducted to examine the roles of teacher efficacy in implementing the innovative constructivist instruction. The results showed that the positive correlation between teacher efficacy and constructivist instruction was stronger than the correlation between teacher efficacy and didactic instruction. The study suggests that policy makers and school leaders should try to improve teacher’s efficacy beliefs so that innovative instruction could be effectively implemented by school teachers.  相似文献
