可譯與不可譯悼劉殿爵教授

踏莎行 送殿兒赴英倫 絕崤分携,危樓獨佇.萋萋草綠王孫去. 老來别易見應難,臨歧忍作傷心語.病掩孤檠,夢回疏杵.千山萬水愁風雨.東西南北總天涯,離魂隨汝知何處! 這是香港詞人番禺劉景堂(1887-1963)一九六○年所作,時年七十四歲.     

Reproducing kernel resolution space and its applications—II

This paper extends the concept of a reproducing kernel resolution space to a Banach space setting. The resultant reproducing kernel resolution space, however, remains a Hilbert space thereby permitting a number of problems in mathematical system theory to be transformed from Banach space to Hilbert space. Particular emphasis is given to the study of Banach space valued random variables and the scattering operator formalism for an electric network.     

Educational Reform and Research in Hong Kong: A Request for Comprehensive Knowledge

When Hong Kong is moving towards a knowledge society in the new millennium, research is clearly necessary to provide a knowledge base for educational development and reform to meet the challenges of globalization and high technology in the world. This report aims to review the education policy environment in Hong Kong and see whether research can be encouraged to support policy development and practice improvement. Particularly, the report will give a brief introduction to the recent initiatives in Hong Kong school education since the establishment of the Special Administrative Region in 1997 and discusses the potential research agenda to support the ongoing education reforms at the school system. This revised version was published online in July 2006 with corrections to the Cover Date.     

Specification Search for Identifying the Correct Mean Trajectory in Polynomial Latent Growth Models

This study investigated the optimal strategy for model specification search under the latent growth modeling (LGM) framework, specifically on searching for the correct polynomial mean or average growth model when there is no a priori hypothesized model in the absence of theory. In this simulation study, the effectiveness of different starting models on the search of the true mean growth model was investigated in terms of the mean and within-subject variance-covariance (V-C) structure model. The results showed that specifying the most complex (i.e., unstructured) within-subject V-C structure with the use of LRT, ΔAIC, and ΔBIC achieved the highest recovery rate (>85%) of the true mean trajectory. Implications of the findings and limitations are discussed.     

Effects of Technology-Mediated Vocabulary Intervention for Third-Grade Students with Reading Difficulties

Abstract

In this experimental study, we examined the effects of a technology-mediated intervention to improve students’ understanding of academic vocabulary and its impact on measures of vocabulary and comprehension. The Vocabulators program was implemented in two states involving 24 teachers and 200 third-grade students identified as in need of supplemental vocabulary instruction. Individual students within each classroom were randomly assigned to treatment (n?=?100) or typical instructional practices (n?=?100) conditions. In the treatment condition, students received, on average, 29 lessons on vocabulary and comprehension. Results of linear regression analyses showed statistically significant and practical effects on experimenter-developed proximal measures of decoding (ES = 0.52), expressive vocabulary (ES = 0.78), receptive vocabulary (ES = 0.51), and near transfer measures of understanding vocabulary in sentences (ES = 0.65), and informational text comprehension (ES = 0.28). Group performance did not differ statistically on near transfer measures of sentence verification with vocabulary and narrative text comprehension as well as distal standardized measures of general vocabulary or reading comprehension. Findings suggest the potential impact of technology-based vocabulary/comprehension lessons to supplement typical instruction.     

Reading for different goals: the interplay of EFL college students' multiple goals,reading strategy use and reading comprehension

This study explored the effects of achievement goals on English as a foreign language (EFL) college students' reading strategy use and reading comprehension from the perspective of multiple goals. Fifty‐seven participants verbalised their thoughts while reading an English expository essay. They also completed assessments on their reading goal profiles and reading proficiency. The results of stimulated recall indicated that participants with profiles characterised by strong mastery and strong performance goals used intra‐sentential, inter‐paragraph, intra‐paragraph and monitoring/evaluating strategies significantly more frequently than did their counterparts. In contrast, participants with profiles characterised by strong mastery but weak performance goals utilised these strategies more often than those participants with weak mastery but strong performance goals. The strong‐mastery–strong‐performance goal profile served as a significant, positive predictor for degrees of reading comprehension. In line with these findings, suggestions for EFL reading pedagogy are provided.     

Learning as boundary-crossing in school–university partnership

This paper points out that globalization has raised fundamental questions about knowing and learning and that it is essential for educators to engage in collective knowledge generation by crossing community boundaries. Drawing on the theoretical framework of Activity Theory, this paper reports on a study on the expansive learning that was afforded by a school–university partnership as university tutors, mentor teachers and student teachers engaged in a new activity system mediated by lesson study. The study showed that in the course of resolving contradictions that were inherent in the boundary zone, they negotiated the mediating tool and consequently, the activity system was transformed from helping student teachers learn to teach into learning for all participants. This paper concludes that it is essential for teachers and teacher educators to develop the capability to engage in expansive learning through tackling ill-defined problems in boundary zones.     

Cultivating better learning attitudes: a preliminary longitudinal study

Abstract

The use of flipped classrooms, blended learning environments and the application of technology has been extensively studied and reported in the literature, but the impact of learning activity design on cultivating better learning attitudes has rarely been explored. A rapid adoption of ‘e-schoolbag’ in basic education in China has been observed in recent years. Its impact on academic performance varies from different ways of e-schoolbag adoption. We conducted a two-year longitudinal study to review the relationship between learning behaviours and academic performance in a primary school with a blended learning environment, and investigated how interventions through learning activity redesign could improve the academic performance by cultivating better learning attitudes. The results show that learning attitudes are positively related to academic performance with proper learning activity design. It is therefore suggested that teachers’ interventions through learning activity redesign can cultivate better learning attitudes and thus improve academic performance for learners.     

Enhancing English among second language learners: the pre‐school years

Informed by knowledge of linguistics, research findings in the areas of monolingual and bilingual acquisition, dyslexia and speech therapy clinical practice, five factors are proposed to argue that the acquisition of English by young non‐native learners can be enhanced by learning activities which take into account factors of developmental sequence in language acquisition, language‐specific properties, the relationship between oral and written language, the what‐to‐learn‐first issue and the quality of the language input. Proper language goals can be set and appropriate activities designed, only if the language input provider interacts with a learner in a concrete activity while being sensitive to the developmental trajectory of monolingual speaking children, the development of the less dominant language in a bilingual child, the prosodic and phonological differences between the learner's mother tongue and the target language, the importance of phonological awareness which defines dyslexia, the use of non‐abstract language structures grounded in concrete lexical items in the early stage of language acquisition and the strategy of expanding learners' utterance by one element as used in speech therapy.
