Going beyond textbooks: a study on seamless science inquiry in an upper primary class     

Yanjie Song  Siu Cheung Kong 《Educational Media International》2014,51(3):226-236

This paper reports an initial study on investigating inquiry-based learning in science in an upper primary class guided by an inquiry-based learning model in a seamless learning environment. Two questions are addressed: (1) how students advanced their domain knowledge?; and (2) how students developed their inquiry skills? One teacher and 27 Grade-four students from a local primary school were involved in the study. Six inquiry-based learning lessons focusing on a scientific “rustproofing” learning unit were conducted in a seamless learning environment, initiated in a digital classroom and extended to online discussions on a social network platform. Qualitative data were collected and analysed over two weeks. The results show ways that the students advanced their domain knowledge and developed their inquiry skills.  相似文献   

Audio-based versus text-based asynchronous online discussion: two case studies     

Khe Foon Hew  Wing Sum Cheung 《Instructional Science》2013,41(2):365-380

The main objective of this paper is to examine the use of audio- versus text-based asynchronous online discussions. We report two case studies conducted within the context of semester-long teacher education courses at an Asian Pacific university. Forty-one graduate students participated in Study I. After the online discussions (both audio-based as well as text-based) had ended, qualitative data via student reflections were collected. Results revealed that audio-based discussions have six distinct perceived affordances compared to text-based ones. Interestingly, despite the reported affordances, more than half of the students reported that they preferred to use a text-based discussion if given a choice. The main reasons for their preference were explored. In Study II, 42 undergraduate students took part. Similar to Study I, participants in Study II also indicated that they felt more comfortable using a text-based discussion. The reasons for their preference were also discussed. Directions for future research are proposed.  相似文献

General auditory processing,speech perception and phonological awareness skills in Chinese–English biliteracy     

Kevin K. H. Chung  Catherine McBride‐Chang  Him Cheung  Simpson W. L. Wong 《Journal of Research in Reading》2013,36(2):202-222

This study focused on the associations of general auditory processing, speech perception, phonological awareness and word reading in Cantonese‐speaking children from Hong Kong learning to read both Chinese (first language [L1]) and English (second language [L2]). Children in Grades 2–4 (N=133) participated and were administered measures of IQ, word reading, phonological awareness, speech perception and auditory processing in both L1 and L2. Auditory processing uniquely explained both L1 and L2 word reading. While L1 speech perception accounted for unique variance in L1 word reading, L2 phonological awareness explained unique variance in L2 word reading. In cross‐language comparisons, L1 phonological awareness and speech perception were uniquely associated with L2 word reading, suggesting cross‐language transfer from L1 to L2 only. Results underscore the importance of auditory processing for reading across variable learning contexts.  相似文献   

A Comparison of Phonological Awareness,Lexical Compounding,and Homophone Training for Chinese Word Reading in Hong Kong Kindergartners     

Yan-Ling Zhou  Cathy Y.-C. Fong  Terry T.-Y. Wong  Sum Kwing Cheung 《Early education and development》2013,24(4):475-492

Research Findings: In this study, 88 kindergartners received special training in lexical compounding, homophone awareness, or phonological awareness or were assigned to a control condition over a period of approximately 2 months, with 20-min lessons administered twice per week. Chinese word reading improved significantly more in the lexical compounding group as compared to the other groups. Vocabulary knowledge also showed a trend toward improvement in this group (p < .08) and improved significantly in the homophone group. Although phonological awareness improved most in the phonological awareness training group, this group showed no reading or vocabulary improvements relative to the other groups. Practice or Policy: The results underscore the importance of morphological awareness training for both word reading and vocabulary knowledge in young Chinese children.  相似文献   

The Roles of Hong Kong Preservice Early Childhood Teachers’ Creativity and Zest in Their Self-efficacy in Creating Child-centered Learning Environments     

Sum Kwing Cheung  Ricci Wai-tsz Fong  Suzannie Kit Ying Leung  Elsa Ka-wei Ling 《Early education and development》2013,24(6):788-799

Research Findings: This study investigated the relationships of preservice teachers’ year of study in the teacher education program, creativity, zest, and self-efficacy in managing children’s behaviors to self-efficacy in creating child-centered learning environments. Data were collected from 275 Hong Kong preservice teachers via self-reported questionnaires. Results showed that creativity had a direct positive linkage with self-efficacy in creating child-centered learning environments. Zest was associated with self-efficacy in creating child-centered learning environments, however, indirectly through self-efficacy in managing children’s behaviors. Year of study was unrelated to both self-efficacies. Practice or Policy: Preservice teachers’ creativity and zest can be conceptualized as personal resources for creating child-centered environments. Teacher education programs should therefore incorporate components of fostering pre-service teachers’ own creativity and zest.  相似文献   

Solving ill-structured problems in asynchronous online discussions: built-in scaffolds vs. no scaffolds     

Connie Siew Ling Ng  Wing Sum Cheung  Khe Foon Hew 《Interactive Learning Environments》2013,21(2):115-134

Solving ill-structured problems is regarded as an important learning outcome in education as it allows learners to apply theories learnt into real practice. An asynchronous online discussion, with extended time for reflection, is an appropriate learning environment to engage learners in solving ill-structured problems. However, scaffolds may be needed to support learners in the online discussions. This study explores the effect of online scaffolds in supporting a group of graduate students' ill-structured problem-solving processes in asynchronous online discussions. The results of this study showed that the use of the online scaffolds did not lead to a significant difference in the number of ill-structured problem-solving processes. Further analysis revealed that wrong selection of message labels and under-usage of sentence openers affected the results of this study. Improvements for online scaffolds include having more precise message labels and sentence openers based on Socratic questioning approach.  相似文献   

Constructing Approximate Confidence Intervals for Parameters With Structural Equation Models     

Mike W.-L. Cheung 《Structural equation modeling》2013,20(2):267-294

Confidence intervals (CIs) for parameters are usually constructed based on the estimated standard errors. These are known as Wald CIs. This article argues that likelihood-based CIs (CIs based on likelihood ratio statistics) are often preferred to Wald CIs. It shows how the likelihood-based CIs and the Wald CIs for many statistics and psychometric indexes can be constructed with the use of phantom variables (Rindskopf, 1984 Rindskopf, D. 1984. Using phantom and imaginary latent variables to parameterize constraints in linear structural models. Psychometrika, 49: 37–47. [Crossref], [Web of Science ®] , [Google Scholar]) in some of the current structural equation modeling (SEM) packages. The procedures to form CIs for the differences in correlation coefficients, squared multiple correlations, indirect effects, coefficient alphas, and reliability estimates are illustrated. A simulation study on the Pearson correlation is used to demonstrate the advantages of the likelihood-based CI over the Wald CI. Issues arising from this SEM approach and extensions of this approach are discussed.  相似文献   

Perceived critical mass and collective intention in social media-supported small group communication     

Xiao-Liang Shen  Christy M.K. Cheung  Matthew K.O. Lee 《International Journal of Information Management》2013

The increasing popularity of Web 2.0 has dramatically changed the way in which people communicate with others in their daily life or work. However, the use of social media is fundamentally different from that of traditional information technologies. Specifically, it requires collective efforts and interdependence between two or more people, and thus the usage behavior is no longer an individual's own decision or plan. Built on critical mass theory and social influence processes, this study tries to make an attempt to understand the determinants of collective intention (we-intention), which represents one's perception of a group of people acting as a unit. Instant messaging, one of the most popular social media platforms, has been chosen for investigation, and findings from a survey showed that perceived critical mass influenced we-intention both directly and indirectly through group norm and social identity. Recognizing the importance and relevance of collective intention will advance current understanding beyond individual intention-based models which are widely adopted in prior IS research. This study may be limited by having not included other alternative social technologies, but we leave this work for future research.  相似文献
