ABSTRACT Teaching Chinese to second language learners is a challenge for preschool teachers in Hong Kong so effective teacher professional development programmes are urgently needed to enhance their knowledge and skills. An Integrative Model Teacher Professional Development Programme which incorporates three theoretical underpinnings (i.e., culturally responsive teaching, meaningful and pleasurable learning, and effective teaching of Chinese as a second language) is designed to equip preschool teachers with knowledge, skills, and awareness in teaching Chinese to ethnic minority students. Through qualitative interviews with 15 in-service preschool teachers who joined the Programme, teachers’ perceptions and changes in three theoretical areas of teaching Chinese to ethnic minority students were explored. Particularly, teachers increased their awareness of ethnic minority cultures, developed empathy with ethnic minority children and their families, gained knowledge of implementing culturally responsive teaching and meaningful and pleasurable learning of Chinese. The role of teacher sharing in effective professional development was highlighted. 相似文献

ABSTRACT A total of 96 children aged 11 to 12 years were given statistical inference problems (base‐rate and law of large numbers) designed to test the effects of wording on their answers. The wording of the problems was manipulated to make the information on base‐rates and on the law of large numbers either more salient or less salient. The latter condition was established by adding extraneous information to base‐rates, or, in the case of the law of large numbers, making the context unfamiliar or focusing choice on a particular person rather than on the group. A significant main effect of wording was found across all problems in favour of the salient condition. The results indicated that the children had a high level of statistical intuition and that they knew when to reason statistically and when not to. 相似文献

The traditional focus of intergovernmental services research has been on technological development, not on user acceptance; yet user acceptance of intergovernmental services in each electronic government (e-Government) implementation affects the ultimate success of the e-Government project. In the e-Government implementation context, many governments have invested huge amounts of money and manpower to make intergovernmental services both available and user-accepted, although some individuals have no intention of using them. The electronic document management system (EDMS) is the most popular intergovernmental service in the e-Government project. Thus, e-Government researchers need to identify the factors that determine user acceptance of EDMS. 相似文献

This study adopted design and development research methodology (Richey & Klein, Design and development research: Methods, strategies, and issues, 2007) to systematically investigate the process of applying instructional design principles, human–computer interaction, and software
engineering to a performance support system (PSS) for behavior management in a classroom. The purpose was to examine how a
proposed instructional design framework based on Ausubel’s (The psychology of meaningful verbal learning, 1963) advance organizer theoretical approach could be used to address inherent problems of technically driven PSSs. Development
data were collected from a six-phase participatory rapid prototyping process using both qualitative and quantitative methods.
Findings indicated that (a) the advance organizer concept combined with a matrix design metaphor provided an effective way
to illustrate conceptual connections and relations among PSS modules and their elaborated information, (b) the system served
as a reference to support participants for exchanging ideas with other teachers as well as with parents of students, and (c)
the rapid prototyping process established parameters that helped the project team maintain a focus on users and collect data
useful for advancing to a higher phase of system development. Potential drawbacks pertaining to the proposed design strategies
and their possible corrective actions are also reported and discussed. 相似文献

The purpose of this study was to address this problem by applying a new hybrid fuzzy multiple criteria decision-making model including (a) using the fuzzy decision-making trial and evaluation laboratory (DEMATEL) technique to construct the fuzzy scope influential network relationship map (FSINRM) and determine the fuzzy influential weights of the fuzzy DEMATEL-based analytic network process (DANP) as well as (b) the modified VIKOR method combining fuzzy influential weights of fuzzy DANP to integrate each criterion of fuzzy performance gaps into dimensions and, overall, to examine the interdependent and feedback problems among various dimensions/criteria of cloud e-learning services for creating the excellent improvement plan based on the FSINRM to implement the strategic orientations. An empirical case of the network communication service industry was used as an example to show the proposed methods and ultimately present the most effective improvement plan for decision-makers to achieve the aspiration level. 相似文献

Body donation is important for medical education and academic research. However, it is relatively rare in Hong Kong when compared with many Western countries. Comprehensive research has been performed on the motivation for body donation in Western countries; however, there is still insufficient research on body donation in Hong Kong to provide information on how to increase the body‐donation rate. To understand the factors involved in the decision to donate one's body, the authors interviewed a registered donor and the daughter of another donor in Hong Kong. The authors interpreted the information collected in light of the available published reports, which mostly focus on body donation in Western countries. Despite the consistency of some demographic factors and motivations between the participants in our study and those investigated in the published reports from Western countries, there are differences in education level and socioeconomic status between the donors in our study and those from Western studies. The authors also suggest that Confucianism and Buddhism in Chinese culture may motivate potential body donors in Hong Kong. Other important factors that influence the body‐donation decision may include family members' body donation, registration as organ donors, and good doctor–patient relationships. Although case report studies have their limitations, this study allows us to explore the complexity of events and establish the interconnectivity of factors involved in body donation, which could not be achieved in previous survey‐based studies. © 2012 American Association of Anatomists. 相似文献
