This article reports on the development and validation of a rubric for assessing students’ written responses to artworks. Since the implementation of the Hong Kong New Senior Secondary Curriculum in 2009, art educators have seen responding to artworks as increasingly important. In this context, the Art Criticism Assessment Rubric (ACAR) was developed. On the basis of Feldman's and Geahigan's theories of art criticism, eight evaluation criteria were identified. The inter‐rater reliability (IRR) of the ACAR was examined. A preliminary IRR test was conducted and an excellent intra‐class correlation coefficient (ICC) value of .91 was obtained. For the main study, six independent raters, who were divided into three groups of two, were trained and invited to rate 87 art criticism essays written by students from eight secondary schools. Most dimensions of the ACAR achieved good ICC values. The results show that the ACAR is an acceptable rubric for providing a reliable assessment of students’ written responses to artworks. However, two dimensions, Originality and Balanced Views and Application of Aesthetic and Contextual Knowledge, obtained poor ICC values. This may be owing to the lack of consensus on the definition of originality and the raters' unfamiliarity with the concept of aesthetic knowledge. The researchers suggest that dimension‐specific samples rated from high to low scores should be provided in raters’ training.  相似文献

Research Findings: Across 63 Hong Kong families, both Filipina domestic helpers and mothers separately rated their own caregiving style (warmth and control) and kindergarten children's social competence. Results indicated that Filipina helpers rated themselves as higher in warmth than mothers did. In addition, self-rated warmth of both caregivers, and Filipina domestic helpers' self-perceived control were correlated with children's social competence. With ratings of warmth and control from both Filipina helpers and mothers included in separate regression equations, mothers' warmth was a strong unique correlate of all measures of children's social competence. However, Filipinas' warmth was uniquely associated with children's responsibility only, whereas their control was uniquely associated with children's assertion and responsibility. Practice or Policy: Results extend previous research on the importance of nonparental caregivers for children's social development in a new cultural context.  相似文献

As the English language has become a global lingua franca today, it is not surprising that changes in attitudes and perceptions towards learning English in the international context have taken place at the same time. In this paper, I critically examine the notion of ‘integrative motivation’ in the literature of second language (L2) learning with respect to the changing role of the English language in the global context. In particular, this paper attempts to re-conceptualise the notion of integrative motivation by considering the results of recent empirical research on L2 motivation. It is argued that the predominant motivation of learning English among most L2 learners is no longer concerned with ‘integration’ in the target native English-speaking culture, but with the construction of a ‘bi-cultural’ or ‘world citizen’ identity, as well as identification with the international community. The paper ends by suggesting new ways of understanding the concept of motivation in L2 learning in today’s global context.  相似文献

Meta-analysis is the statistical analysis of a collection of analysis results from individual studies, conducted for the purpose of integrating the findings. Structural equation modeling (SEM), on the other hand, is a multivariate technique for testing hypothetical models with latent and observed variables. This article shows that fixed-effects meta-analyses with the following characteristics can be modeled in the SEM framework: (a) using any type of effect size; (b) including categorical and continuous moderators; and (c) including multivariate effect sizes. Empirical examples in LISREL syntax are used to demonstrate the equivalence between the meta-analytic and SEM approaches. Future directions for and extensions to this approach are discussed.  相似文献

Regression mixture models, which have only recently begun to be used in applied research, are a new approach for finding differential effects. This approach comes at the cost of the assumption that error terms are normally distributed within classes. This study uses Monte Carlo simulations to explore the effects of relatively minor violations of this assumption. The use of an ordered polytomous outcome is then examined as an alternative that makes somewhat weaker assumptions, and finally both approaches are demonstrated with an applied example looking at differences in the effects of family management on the highly skewed outcome of drug use. Results show that violating the assumption of normal errors results in systematic bias in both latent class enumeration and parameter estimates. Additional classes that reflect violations of distributional assumptions are found. Under some conditions it is possible to come to conclusions that are consistent with the effects in the population, but when errors are skewed in both classes the results typically no longer reflect even the pattern of effects in the population. The polytomous regression model performs better under all scenarios examined and comes to reasonable results with the highly skewed outcome in the applied example. We recommend that careful evaluation of model sensitivity to distributional assumptions be the norm when conducting regression mixture models.  相似文献

Immiscible aqueous phases, formed by dissolving incompatible solutes in water, have been used in green chemical synthesis, molecular extraction and mimicking of cellular cytoplasm. Recently, a microfluidic approach has been introduced to generate all-aqueous emulsions and jets based on these immiscible aqueous phases; due to their biocompatibility, these all-aqueous structures have shown great promises as templates for fabricating biomaterials. The physico-chemical nature of interfaces between two immiscible aqueous phases leads to unique interfacial properties, such as an ultra-low interfacial tension. Strategies to manipulate components and direct their assembly at these interfaces needs to be explored. In this paper, we review progress on the topic over the past few years, with a focus on the fabrication and stabilization of all-aqueous structures in a multiphase microfluidic platform. We also discuss future efforts needed from the perspectives of fluidic physics, materials engineering, and biology for fulfilling potential applications ranging from materials fabrication to biomedical engineering.  相似文献

Students’ attitudes toward chemistry lessons in school are important dependent variables in curriculum evaluation. Although a variety of instruments have been developed by researchers to evaluate student attitudes, they are plagued with problems such as the lack of theoretical rationale and of empirical evidence to support the construct validity of data. This paper describes a study of students’ attitudes toward chemistry lessons in Hong Kong secondary schools. One of the scales in the Test of Science‐Related Attitudes developed by Fraser was modified to form an Attitude Toward Chemistry Lessons Scale (ATCLS). The construction of the ATCLS was based on a theoretical model with four dimensions: liking for chemistry theory lessons, liking for chemistry laboratory work, evaluative beliefs about school chemistry, and behavioural tendencies to learn chemistry. The arguments for inclusion of these four dimensions are presented. The final version of ATCLS was administered to 954 students. The results of confirmatory factor analysis indicated that there was a good fit between the hypothesised model and the observed data.  相似文献

Media education has been around for quite some time in the West (Bazalgette et al. 1990 Bazalgette, C., Bevort, E. and Savino, J. 1990. New directions: Media education worldwide, London: BFI.  [Google Scholar]), but it only started to gain acceptance in Asia (Cheung 2005 Cheung, C. K. 2005. Media education in Hong Kong: From civic education to curriculum reform. The Asia-Pacific Education Researcher, 14(1): 2745.  [Google Scholar]), particularly in Hong Kong, in the last decade. Recently, it has been gaining more attention in Hong Kong thanks to the curriculum reform in which liberal studies will become one of the four core subjects to be taken by students in the New Senior Secondary Curriculum and media is one of the six themes to be studied in the subject of liberal studies. This article argues for the need for teaching media education in liberal studies and shows the many connections between the two subjects that facilitate this integration.  相似文献
