Componential skills of beginning writing: An exploratory study     

Kim YS  Otaiba SA  Puranik C  Folsom JS  Greulich L  Wagner RK 《Learning and individual differences》2011,21(5):517-525

The present study examined the components of end of kindergarten writing, using data from 242 kindergartners. Specifically of interest was the importance of spelling, letter writing fluency, reading, and word- and syntax-level oral language skills in writing. The results from structural equation modeling revealed that oral language, spelling, and letter writing fluency were positively and uniquely related to writing skill after accounting for reading skills. Reading skill was not uniquely related to writing once oral language, spelling, and letter writing fluency were taken into account. These findings are discussed from a developmental perspective.  相似文献   

Towards technology integration: the impact of motivational and volitional email messages     

ChanMin Kim  John M. Keller 《Educational technology research and development : ETR & D》2011,59(1):91-111

The purpose of this study was to determine the effects of motivational and volitional email messages (MVEM) on preservice teachers’ motivation, volition, performance, and their attitudes toward technology integration. Each of four sections in an educational technology course for preservice teachers was randomly assigned to one of two groups: one group which received MVEM constructed based on audience analysis; and the other which received placebo email messages consisting of class activities reminders without audience analysis. Results indicated that the group provided with MVEM showed higher volition and more positive attitudes toward technology integration than the group provided with placebo messages even though there was no difference in motivation or performance. These results suggest that MVEM can serve as an effective tool for facilitating preservice teachers’ positive attitudes toward technology integration. Implications for the design and development of interventions or systems for technology integration are discussed and further research is recommended.  相似文献   

Korean elementary school students’ English learning demotivation: a comparative survey study   总被引：1，自引：0，他引：1  

Tae-Young Kim 《Asia Pacific Education Review》2011,12(1):1-11

This study explores Korean elementary school students’ decreased motivation for English learning by analyzing the questionnaire data obtained from 6,301 students in a large city in South Korea. The students’ school grades and their prior experience in private institutes were considered as the major factors behind the decrease in their motivation. There was a statistically significant and consistent decrease in the students’ satisfaction with their English learning experience; expectation of ultimate success in English; and intrinsic/extrinsic motivation and integrative/instrumental motivation. Prior experience in attending private institutes had a substantial impact on the students’ motivation. Those who attended private institutes (hakwons) exhibited higher levels of instrumental and intrinsic motivation. However, in terms of other motivational constructs of integrative and extrinsic (parental, academic) motivation, private instruction had a negligible or negative impact. By comparing the results with those of Lamb (2007), the present study proposes that Korean students should be made to internalize the beneficial role played by English so that their English learning motivation can be maintained.  相似文献   

Inquiry-Based Science and Technology Enrichment Program: Green Earth Enhanced with Inquiry and Technology     

Hanna Kim 《Journal of Science Education and Technology》2011,20(6):803-814

This study investigated the effectiveness of a guided inquiry integrated with technology, in terms of female middle-school students’ attitudes toward science/scientists and content knowledge regarding selective science concepts (e.g., Greenhouse Effect, Air/Water Quality, Alternative Energy, and Human Health). Thirty-five female students who were entering eighth grade attended an intensive, 1-week Inquiry-Based Science and Technology Enrichment Program which used a main theme, “Green Earth Enhanced with Inquiry and Technology.” We used pre- and post-attitude surveys, pre- and post-science content knowledge tests, and selective interviews to collect data and measure changes in students’ attitudes and content knowledge. The study results indicated that at the post-intervention measures, participants significantly improved their attitudes toward science and science-related careers and increased their content knowledge of selected science concepts (p < .05).  相似文献   

Reclaiming Kindergarten: Part I. Questions about Theory and Practice     

Dominic F. Gullo  Kim Hughes 《Early Childhood Education Journal》2011,38(5):323-328

The purpose of this article is to describe the crisis that exists in kindergarten today related to maintaining developmentally and culturally appropriate practice while at the same time addressing the academic standards set forth by most states. In Part I, three questions are posed, the answers to which seek to elucidate possible solutions to this dilemma. The questions center on issues related to developmentally appropriate practice, intentional teaching, and assessment. Research and expert opinion associated to each of these areas are discussed, and examples of classroom practice are used to illustrate the effective implementation of these principles in a kindergarten classroom.  相似文献

Framing the crisis by one's seat: a comparative study of newspaper frames of the Asiana crash in the USA,Korea, and China     

Yan Yan  Yeojin Kim 《亚洲交流杂志》2015,25(5):486-506

This study compared newspaper frames of the 2013 Asiana Airlines crash in the three countries involved: the USA, Korea, and China. The results revealed distinct patterns of news coverage under the particular influence of national interests. The responsibility frame was the most frequently used, but the attribution of responsibility varied across the three countries. US newspapers overwhelmingly attributed the causation to pilot error, Korean media framed the causation as being open to multiple explanations, and Chinese newspapers were less likely to speculate about causation before the final official conclusion was reached. US and Korean media maintained a negative tone toward each other, while Chinese newspapers took a similar standpoint as the US media but were slightly less negative toward Korea. Further, divergence of news frames used across countries was associated with the different use of sources by different newspapers across countries. In particular, Korean media indicated reluctance to use US officials and a preference to cite alternative sources which offered diverse opinions regarding the attribution of responsibility. Finally, emotions of the crash stories varied by attributions of causation in Korean but not in the other countries’ news reports.  相似文献

A semantic Bayesian network approach to retrieving information with intelligent conversational agents     

Kyoung-Min Kim  Jin-Hyuk Hong  Sung-Bae Cho 《Information processing & management》2007

As access to information becomes more intensive in society, a great deal of that information is becoming available through diverse channels. Accordingly, users require effective methods for accessing this information. Conversational agents can act as effective and familiar user interfaces. Although conversational agents can analyze the queries of users based on a static process, they cannot manage expressions that are more complex. In this paper, we propose a system that uses semantic Bayesian networks to infer the intentions of the user based on Bayesian networks and their semantic information. Since conversation often contains ambiguous expressions, the managing of context and uncertainty is necessary to support flexible conversational agents. The proposed method uses mixed-initiative interaction (MII) to obtain missing information and clarify spurious concepts in order to understand the intention of users correctly. We applied this to an information retrieval service for websites to verify the usefulness of the proposed method.  相似文献   

High-performance FAQ retrieval using an automatic clustering method of query logs     

Harksoo Kim  Jungyun Seo 《Information processing & management》2006

To resolve some of lexical disagreement problems between queries and FAQs, we propose a reliable FAQ retrieval system using query log clustering. On indexing time, the proposed system clusters the logs of users’ queries into predefined FAQ categories. To increase the precision and the recall rate of clustering, the proposed system adopts a new similarity measure using a machine readable dictionary. On searching time, the proposed system calculates the similarities between users’ queries and each cluster in order to smooth FAQs. By virtue of the cluster-based retrieval technique, the proposed system could partially bridge lexical chasms between queries and FAQs. In addition, the proposed system outperforms the traditional information retrieval systems in FAQ retrieval.  相似文献
