One of the main features of globalization is the increasing mobility of population. As an immigrant society, Hong Kong has witnessed waves of Mainland Chinese arrivals and assimilation into her mainstream, particularly around the change of sovereignty period. School-aged children constitute a substantial fraction of the new population. Given their potential impact on Hong Kong's present and future, how these immigrant youngsters perform in school has always been a concern to the public as well as the government. This study compared Hong Kong 8th-graders' mathematics performance in the four rounds of the Trends in International Mathematics and Science Study by their immigrant status. The results showed that the first-generation immigrant students' performance had obvious retrogression compared to native students in the past years. Among the natives, non-local-born students with only their father born in Hong Kong had the most similar performance as the first-generation immigrants. The causes for the differences are explored from both internal and external perspectives. 相似文献

Comparisons of large samples of course and teaching evaluation questionnaire data show consistent disciplinary differences. The current study examined the disciplinary differences in a theoretical model positing the impact of the perceived nature of teaching and learning environment on the development of generic capabilities by testing of (1) whether a common model of good teaching operated across disciplines and (2) the extent of deployment of teaching variables and their impact on learning outcomes. The sample consisted of 3,305 first and third year Chinese undergraduates of a university in Hong Kong, divided into four broad disciplinary groupings. Multiple-group structural equation modelling analysis showed configural invariance of the hypothesised model, suggesting a common model of good teaching across disciplines; and significant differences in the magnitude of structural paths and latent mean values across the four disciplinary groups were obtained reflecting differences between disciplines in the extent to which elements within the teaching and learning environment were brought into play. Possible reasons in terms of the epistemological nature of the disciplines were given to explain for the disciplinary variations. 相似文献

Though it is generally believed that doing homework promotes better learning, no consensus has been achieved concerning its importance and relevance to students’ achievement. The historical up-and-down status of public attitudes toward homework indicates that understanding about the role of homework in students’ learning is far from comprehensive and clear. The literature shows that much research effort has been devoted to the relationship between amount of homework and achievement, but little on quality of homework and how it has been used. Applying a 2-level hierarchical linear model on the TIMSS 2003 data, this study investigated the relationship between classroom practices on homework and 8th grade students’ mathematics achievement in Hong Kong in three dimensions: frequency and amount of homework, types of homework, and usage modes of homework. The results showed that while the time spent on daily mathematics homework had significantly positive effect on students’ TIMSS results, no effect was observed on the frequency of homework assigned. Out of three types of homework, only homework of the problem/question type demonstrated significant effect. The practice of having students start homework in class had negative influence on students’ learning outcome. Implications and suggestions for educational practice and future research were then discussed. 相似文献

This study examined how chronic loneliness is associated with gratifications‐sought and its effect on Internet use. Results from a telephone survey of 864 Internet users of 16‐years of age or older found that surveillance, affection, and social interaction were strongest instrumental use of the Internet followed by ritualized use such as entertainment, escape, and arousal. The proposition that the chronically lonely derive fewer gratifications from Internet use than do the situationally lonely and the nonlonely people was not supported. Moreover, no consistent patterns of ritualized or instrumental use of the Internet were found when comparing the chronically lonely and the nonlonely groups. However, the hypothesis that chronically lonely persons will report less active use of the Internet such as using e‐mail, surfing the WWW, reading online news, and playing online games than do the situationally lonely and the nonlonely persons received much support. Finally, regression results show that instrumental gratifications were more predictive of Internet activities for the nonlonely group than the lonely group. Implications of loneliness on Internet use in Chinese culture are discussed. 相似文献
