Metacognitive development and moving away     

Kevin Downing  Richard Ho  Kristina Shin  Lilian Vrijmoed  Eva Wong 《Educational studies》2007,33(1):1-13

It is now largely accepted that social and cultural factors have a significant impact on cognitive development in children. Piaget acknowledged the impact of social factors and peer interaction on cognitive development. However, there has been relatively little work on the impact of social and cultural factors on the development of metacognition in first‐year university students. Using the Learning and study strategies inventory (LASSI) as a measure of metacognition, this study samples first‐year undergraduates in Hong Kong (N = 1815) and identifies significant differences in metacognitive abilities between students living in their home environment and those who have moved away from their family and, in some cases, culture, to pursue undergraduate education.  相似文献   

Using relief texture for interactive and tangible virtual environments     

Junae Kim  Seonhyung Shin  Gerard Jounghyun Kim 《浙江大学学报(A卷英文版)》2008,9(12):1656-1665

This paper first introduces a way to improve interactivity with high polygon count virtual objects through the ＂mixed＂ use of image-based representation within one object. That is, both 3D polygonal and image-based representations are maintained for an object, and switched for rendering depending on the functional requirement of the object. Furthermore, in order to reduce the popping effect and provide smooth and gradual transition during the object representation switch, the object is subdivided with the subdivided parts possibly represented differently, i.e., using 3D models or images. As for the image-based representation, the relief texture （RT） method is used. In particular, through the use of the mixed representation, a new way called TangibleScreen is proposed to provide object tangibility by associating the image-based representation with a physical prop （projecting the RTs） in a selective and flexible way. Overall, the proposed method provides a way to maintain an interactive frame rate with selective perceptual details in a large-scale virtual environment, while allowing the user to interact with virtual objects in a tangible way.  相似文献   

Schema and constraints-based matching and merging of Topic Maps     

Jung-Mn Kim  Hyopil Shin  Hyoung-Joo Kim 《Information processing & management》2007

In this paper, we propose a multi-strategic matching and merging approach to find correspondences between ontologies based on the syntactic or semantic characteristics and constraints of the Topic Maps. Our multi-strategic matching approach consists of a linguistic module and a Topic Map constraints-based module. A linguistic module computes similarities between concepts using morphological analysis, string normalization and tokenization and language-dependent heuristics. A Topic Map constraints-based module takes advantage of several Topic Maps-dependent techniques such as a topic property-based matching, a hierarchy-based matching, and an association-based matching. This is a composite matching procedure and need not generate a cross-pair of all topics from the ontologies because unmatched pairs of topics can be removed by characteristics and constraints of the Topic Maps. Merging between Topic Maps follows the matching operations. We set up the MERGE function to integrate two Topic Maps into a new Topic Map, which satisfies such merge requirements as entity preservation, property preservation, relation preservation, and conflict resolution. For our experiments, we used oriental philosophy ontologies, western philosophy ontologies, Yahoo western philosophy dictionary, and Wikipedia philosophy ontology as input ontologies. Our experiments show that the automatically generated matching results conform to the outputs generated manually by domain experts and can be of great benefit to the following merging operations.  相似文献   

Effects of learner control,advisement, and prior knowledge on young students' learning in a hypertext environment   总被引：4，自引：0，他引：4  

E. Christine Shin  Diane L. Schallert  Wilhelmina C. Savenye 《Educational technology research and development : ETR & D》1994,42(1):33-46

This study was an investigation of the effects of learner control and of advisement in a hypertext learning environment with second-grade students who had different levels of prior knowledge about the content. Four treatment conditions crossing two variables, learner control (free access representing network structuring of hypertext vs. limited access representing hierarchical structuring of hypertext), and advisement (advisement vs. no-advisement), were established. From the quantitative and qualitative data, results indicated that: (a) for low prior knowledge (PK) students, the limited-access condition was more effective than the free-access condition, whereas high-PK students were able to function equally well in both conditions; (b) the free-access group reported a higher positive attitude for advisement than for no advisement, but the limited-access group showed no such difference in preference; (c) the low-PK group completed the lesson more quickly without advisement than with advisement, whereas the high-PK group's completion times did not vary across advisement conditions; and (d) analysis of the path data indicated that advisement was helpful in preventing disorientation in the free-access condition.  相似文献   

A Web-based on-machine mould matching and measurement system based on CAD/CAM/CAI integration

INTRODUCTION Today, the manufacturing industry makes con- stant effort in order to construct an E-manufacturing system using information technology for effective production control, and then, it offers the integrated production control to the workers, the production managers, and the consumers, etc. (Lee, 2003; Choi, 2004). In the mould manufacturing industry, the process managers often request paperwork to know the information of the processes on CNC machine tools or they visit the shop…  相似文献   

Browsing software of the Visible Korean data used for teaching sectional anatomy     

Shin DS  Chung MS  Park HS  Park JS  Hwang SB 《Anatomical sciences education》2011,4(6):327-332

The interpretation of computed tomographs (CTs) and magnetic resonance images (MRIs) to diagnose clinical conditions requires basic knowledge of sectional anatomy. Sectional anatomy has traditionally been taught using sectioned cadavers, atlases, and/or computer software. The computer software commonly used for this subject is practical and efficient for students but could be more advanced. The objective of this research was to present browsing software developed from the Visible Korean images that can be used for teaching sectional anatomy. One thousand seven hundred and two sets of MRIs, CTs, and sectioned images (intervals, one millimeter) of a whole male cadaver were prepared. Over 900 structures in the sectioned images were outlined and then filled with different colors to elaborate each structure. Software was developed where four corresponding images could be displayed simultaneously; in addition, the structures in the image data could be readily recognized with the aid of the color-filled outlines. The software, distributed free of charge, could be a valuable tool to teach medical students. For example, sectional anatomy could be taught by showing the sectioned images with real color and high resolution. Students could then review the lecture by using the sectioned and color-filled images on their own computers. Students could also be evaluated using the same software. Furthermore, other investigators would be able to replace the images for more comprehensive sectional anatomy.  相似文献   

The vortex of multiculturalism in South Korea: a critical discourse analysis of the characterization of “multicultural children” in three newspapers     

Jaran Shin 《传播与批判/文化研究》2019,16(1):61-81

This study investigates how multicultural children have been portrayed by the Korean media, where the term is typically used to mean a child of an underprivileged Korean man and a female marriage migrant from a less industrialized neighboring country. Adopting the theoretical lens of critical discourse analysis, I examine news articles published from 2009 to 2013 in the Hankyoreh, the Hankook Ilbo, and the Chosun Ilbo: three daily newspapers representing a full range of progressive, moderate, and conservative political perspectives within society. Analysis reveals that multicultural children have been characterized as a marginalized group, as a threat to the future Korean society, or as global human resources. Given that these discourses are manifestations of underlying ideology, I also explore how these three discourses are conjoined with three competing ideologies in Korea; namely, democracy, nationalism, and neoliberalism. This study concludes by discussing how multiculturalism serves as a discursive framework through which democratic, nationalist, and neoliberal ideas gain their effectiveness.  相似文献   

Evaluation of Korean information infrastructure policy 2000–2010: Focusing on broadband ecosystem change     

Dong-Hee Shin  Sang Hee KweonAuthor vitae 《Government Information Quarterly》2011,28(3):374-387

South Korea has been very active in broadband development for the last decade, which has made major strides in its development. This study evaluates the evolution of Korea's broadband development from the year 2000 to the present day. Historic and archival data related to Korean broadband projects are reviewed in this paper, drawing on broadband ecosystem as a framework for assessment. The purpose of this study is to provide insight into challenges and create a prospectus by offering a socio-technical analysis of broadband development. This will involve the in-depth investigation of the social dynamics, political discourse, and technological choices inherent in the design and development of the next generation of networks. Despite active investment and proactive drive, uncertainty still remains surrounding the evolution of broadband and what impact it may have on the new broadband milieu in Korea. This study will offer an effective adoption/diffusion strategy as well as a viable information policy model for more advanced infrastructure in other countries.  相似文献   

The application of various nonlinear models to describe academic growth trajectories: an empirical analysis using four-wave longitudinal achievement data from a large urban school district     

Tacksoo Shin 《Asia Pacific Education Review》2012,13(1):65-76

This study introduced various nonlinear growth models, including the quadratic conventional polynomial model, the fractional polynomial model, the Sigmoid model, the growth model with negative exponential functions, the multidimensional scaling technique, and the unstructured growth curve model. It investigated which growth models effectively describe student growth in math and reading using four-wave longitudinal achievement data. The objective of the study is to provide valuable information to researchers especially when they consider applying one of the nonlinear models to longitudinal studies. The results showed that the quadratic conventional polynomial model fit the data best. However, this model seemed to overfit the data and made statistical inference problematic concerning parameter estimates. Alternative nonlinear models with fewer parameters adequately fit the data and yielded consistent significance testing results under extreme multicollinearity. It indicates that the alternative models denoting somewhat simpler models would be selected over the conventional polynomial model with more fixed parameters. Other practical issues pertaining to these growth models are also discussed.  相似文献
