How science teachers' concerns about school‐based assessment of practical work vary with time: the Hong Kong experience     

Derek Cheung 《Research in Science & Technological Education》2013,31(2):153-169

School‐based assessment of science students' practical skills has two important roles—as a complement to written papers in public examinations and as a catalyst for enriching the science curriculum in schools. This article describes a quantitative study of the concerns chemistry and biology teachers experience as they engage in the process of implementation of a school‐based assessment scheme for practical work. A 23‐item questionnaire was developed to measure five categories of teacher concern: evaluation, information, management, consequence and refocusing. The nature of each category of teacher concern is discussed in relation to innovation adoption and implementation. Data were collected from 400 chemistry and 412 biology teachers in Hong Kong. Teachers' information and management concerns lessened in intensity when they became experienced users of a school‐based assessment scheme. However, teaching experience alone could not motivate teachers to think more about the impact of school‐based assessment on student learning, their professional development in student assessment and the possible refinements in their school‐based assessment scheme. Concerns‐based interventions are suggested to help teachers grow professionally.  相似文献

A Structural Equation Modeling of the Factors Affecting an Age-friendly Workplace     

Allan B. de Guzman  Hazel N. Amrad  Roren Charisse G. Araullo  Hershey Betricia O. Cheung 《Educational gerontology》2013,39(6):387-400

There has been a growing trend recently to examine the various factors affecting an age-friendly workplace. Through structural equation modelling (SEM), this study purports to test a model that shows the interaction between and among declining memories, wisdom, age discrimination, and an age-friendly workplace in Filipino elderly in a government setting. Two hundred elderly from a large government bank in the Philippines participated in this study. Data were obtained through a self-completion questionnaire and a one-on-one interview. Surprisingly, results revealed that declining memory has no significant effect on wisdom. However, wisdom has a positive impact on age discrimination as does age-discrimination on an age-friendly workplace. The authors discuss the implications of these results and highlight directions for future research.  相似文献

Mining knowledge from natural language texts using fuzzy associated concept mapping     

W.M. Wang  C.F. Cheung  W.B. Lee  S.K. Kwok 《Information processing & management》2008

Natural Language Processing (NLP) techniques have been successfully used to automatically extract information from unstructured text through a detailed analysis of their content, often to satisfy particular information needs. In this paper, an automatic concept map construction technique, Fuzzy Association Concept Mapping (FACM), is proposed for the conversion of abstracted short texts into concept maps. The approach consists of a linguistic module and a recommendation module. The linguistic module is a text mining method that does not require the use to have any prior knowledge about using NLP techniques. It incorporates rule-based reasoning (RBR) and case based reasoning (CBR) for anaphoric resolution. It aims at extracting the propositions in text so as to construct a concept map automatically. The recommendation module is arrived at by adopting fuzzy set theories. It is an interactive process which provides suggestions of propositions for further human refinement of the automatically generated concept maps. The suggested propositions are relationships among the concepts which are not explicitly found in the paragraphs. This technique helps to stimulate individual reflection and generate new knowledge. Evaluation was carried out by using the Science Citation Index (SCI) abstract database and CNET News as test data, which are well known databases and the quality of the text is assured. Experimental results show that the automatically generated concept maps conform to the outputs generated manually by domain experts, since the degree of difference between them is proportionally small. The method provides users with the ability to convert scientific and short texts into a structured format which can be easily processed by computer. Moreover, it provides knowledge workers with extra time to re-think their written text and to view their knowledge from another angle.  相似文献

Education and Socio-Political Transitions in Asia: Diversity and Commonality     

Mark Bray  Wing On Lee 《Asia Pacific Journal of Education》1996,16(1):9-23

This article sets a framework for this special issue of the journal by providing an overview of the topic and a commentary on the ways in which the papers in the special issue may be linked to the theme and to each other. The article is built around the identification of diversity and commonality. On the one hand, the Asian region contains countries with widely varying circumstances and socio-political transitions; but on the other hand are a number of common patterns. Among the commonalities are colonial transitions, interrelationships between education and economic changes, and transitions involving international forces and the changing role of the state.  相似文献

Associations of Warmth and Control of Filipina Domestic Helpers and Mothers to Hong Kong Kindergarten Children's Social Competence     

Hoi Man Ip  Sum Kwing Cheung  Catherine McBride-Chang  Lei Chang 《Early education and development》2008,19(2):284-301

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   

Syntactic based approach for grammar question retrieval     

Lanting Fang  Luu Anh Tuan  Siu Cheung Hui  Lenan Wu 《Information processing & management》2018,54(2):184-202

With the popularity of online educational platforms, English learners can learn and practice no matter where they are and what they do. English grammar is one of the important components in learning English. To learn English grammar effectively, it requires students to practice questions containing focused grammar knowledge. In this paper, we study a novel problem of retrieving English grammar questions with similar grammatical focus. Since the grammatical focus similarity is different from textual similarity or sentence syntactic similarity, existing approaches cannot be applied directly to our problem. To address this problem, we propose a syntactic based approach for English grammar question retrieval which can retrieve related grammar questions with similar grammatical focus effectively. In the proposed syntactic based approach, we first propose a new syntactic tree, namely parse-key tree, to capture English grammar questions’ grammatical focus. Next, we propose two kernel functions, namely relaxed tree kernel and part-of-speech order kernel, to compute the similarity between two parse-key trees of the query and grammar questions in the collection. Then, the retrieved grammar questions are ranked according to the similarity between the parse-key trees. In addition, if a query is submitted together with answer choices, conceptual similarity and textual similarity are also incorporated to further improve the retrieval accuracy. The performance results have shown that our proposed approach outperforms the state-of-the-art methods based on statistical analysis and syntactic analysis.  相似文献
