How are metalinguistic skills associated with vocabulary knowledge in languages with contrasting phonological and morphological properties? To address this question, tasks of phonological awareness and morphological awareness, other reasoning and literacy-related skills, and measures of vocabulary knowledge in Chinese and English, were administered to 217 Hong Kong Chinese kindergarten children learning English as a second language. Syllable-level awareness but not phoneme onset awareness was strongly associated with Chinese vocabulary knowledge; phoneme onset awareness but not syllable awareness was associated with English vocabulary knowledge. In hierarchical regression equations, phonological awareness in English explained unique variance in English vocabulary knowledge but not in Chinese vocabulary knowledge. In contrast, measures of morphological awareness, which were strongly associated with syllable awareness, uniquely explained 13% of the variance in Chinese vocabulary knowledge apart from all other measures included but were not uniquely associated with English vocabulary knowledge. Findings highlight the strong overlap across phonological and morphological awareness in Chinese and the different associations of each to vocabulary acquisition in Chinese (L1) and English (L2) languages.  相似文献   

Incremental cue phrase learning and bootstrapping method for causality extraction using cue phrase and word pair probabilities     

Du-Seong Chang  Key-Sun Choi 《Information processing & management》2006

This work aims to extract possible causal relations that exist between noun phrases. Some causal relations are manifested by lexical patterns like causal verbs and their sub-categorization. We use lexical patterns as a filter to find causality candidates and we transfer the causality extraction problem to the binary classification. To solve the problem, we introduce probabilities for word pair and concept pair that could be part of causal noun phrase pairs. We also use the cue phrase probability that could be a causality pattern. These probabilities are learned from the raw corpus in an unsupervised manner. With this probabilistic model, we increase both precision and recall. Our causality extraction shows an F-score of 77.37%, which is an improvement of 21.14 percentage points over the baseline model. The long distance causal relation is extracted with the binary tree-styled cue phrase. We propose an incremental cue phrase learning method based on the cue phrase confidence score that was measured after each causal classifier learning step. A better recall of 15.37 percentage points is acquired after the cue phrase learning.  相似文献

The Impact of No-Loan Policies on Student Economic Diversity at Public Colleges and Universities     

Zhu  Qiong  Choi  Junghee  Meng  Yi 《Research in higher education》2021,62(6):733-764

To improve college access for low-income students, an increasing number of public colleges and universities have implemented no-loan policies, where student loans are replaced with institutional grant aid that does not require repayment. Using detailed income measures provided by Mobility Report Card data, this study examines the effect of no-loan policies on student economic diversity at public 4-year institutions. Using a difference-in-differences design and the synthetic control method, we found that the adoption of no-loan policies at public institutions increased enrollment shares of low-income students (bottom two family income quintiles). However, the increase was minimal for students from the lowest income quintile, particularly at the most selective institutions. Our findings suggest that although no-loan policies may help improve affordability at public colleges and universities, further efforts are needed to address underrepresentation of students from the lowest part of the income distribution.

Situated cognition and learning environments: Roles,structures, and implications for design   总被引：7，自引：0，他引：7  

Jeong-Im Choi  Michael Hannafin 《Educational technology research and development : ETR & D》1995,43(2):53-69

Situated cognition has emerged as a powerful perspective in providing meaningful learning and promoting the transfer of knowledge to real-life situations. While considerable interest has been generated in situated learning environments, few guidelines exist related to their design. The purpose of this paper is to examine the theoretical underpinnings of situated cognition and to derive implications for the design of situated learning environments. The conceptual framework centers on four basic issues: the role of context, the role of content, the role of facilitation, and the role of assessment.  相似文献

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   

A Study of Changes in the Library and Information Science Curriculum with Evaluation of Its Practicality     

Younghee Noh  In-Ja Ahn  Sang-Ki Choi 《The Journal of Academic Librarianship》2012,38(6):348-364

PurposeThis study analyzed the process of changes in Korean Library and Information Science curriculum and evaluated the courses currently available by using a perception survey of librarians in the field. It also explored a possible demand for new courses, while suggesting compulsory, core, and optional courses for Bachelor's degree curriculum in Library and Information Science worldwide including Korea and the US.Design/Methodology/ApproachThis study progressed through a total of 5 steps as follows: investigating the background of why current courses of Library and Information Science were offered (interview), finding out the current courses in Library and Information Science (homepage search and phone interview), finding out which courses students have actually completed among those available (literature and resource research), evaluating the practicality of the available courses by librarians in the field (survey), and exploring the demand for new courses (survey). In addition, this study analyzed the process of change in the courses offered by investigating the curriculum over the last 20 years.FindingsFirst and foremost, it was found that the decision of which course will be offered is strongly influenced by faculty. Second, in the analysis of the process of opening up new courses, it was revealed that the number of courses is growing and the courses are becoming more diversified and more specific. Third, the survey results of the completion of curriculum for the last three years in 10 universities demonstrate that only 50% of the available courses are being completed. Fourth, in the survey of which courses the librarians in the field think are necessary among the 90 courses suggested, 21 courses scored more than 4 points in a 5-point Likert scale regarding the demand for new courses. Fifth, the new courses which scored high levels of demand points were: Practice in Organizing and Managing Web Resources, Library Planning, Marketing, and Assessment, Understanding Information Technology for Managing Digital Collections, and Information and Communication in a Digital Age. Sixth, this study shows that there is a high level of agreement between courses completed by students and those which gained high levels of demand points in the practicality evaluation.Limitations/ImplicationsAs this study was performed in Korea where the Bachelor's degree course is fundamental, it will contribute valuable information to countries where universities have recently opened or are trying to open programs for Bachelor's degrees in Library and Information Science such as the US, or to curriculum study in countries such as China and Japan which have educational environments similar to Korea. However, similar studies need to be performed in different countries.Originality/ValueThis study has great significance as it has analyzed not only the curriculum of the last 20 years but also discovered how many of the newly created courses have actually been completed by students and the opinions of librarians in the field on these courses; there has not been such an encompassing study as this either inside or outside of Korea.  相似文献   

Transformation of classroom spaces: traditional versus active learning classroom in colleges     

Elisa L. Park  Bo Keum Choi 《Higher Education》2014,68(5):749-771

Educational environment influences students’ learning attitudes, and the classroom conveys the educational philosophy. The traditional college classroom design is based on the educational space that first appeared in medieval universities. Since then classrooms have not changed except in their size. In an attempt to develop a different perspective of educational environment, a new design of classroom, the active learning classroom (ALC), was established at SoongSil University in Korea. Two questionnaire surveys were conducted for diagnosing the educational effects of students’ learning in the ALC and comparing the results with those obtained regarding the traditional classroom. The result proved the existence of a ‘golden zone’ and a ‘shadow zone’ in the traditional classroom, which discriminate students’ learning experiences depending on seating positions. On the contrary, the ALC did not produce such positional discrimination. Students perceived the ALC environment as more inspirational, especially in regards to active class participation. Students with more emphasis on academic achievement showed greater tendency to share information and to create new ideas in the ALC. However, in the traditional classroom setting, only students with high GPAs were more motivated to learn while the gap in learning attitudes was offset in the ALC setting. In-depth discussions about research findings were undertaken and four suggestions were provided in support of school administrators and relevant institutional personnel, faculty members, and researchers for future utilization of the ALC.  相似文献   

Does the reputation of a faculty member’s graduate programme and institution matter for labour market outcomes?     

Jarrett B. Warshaw  Robert K. Toutkoushian  Hyejin Choi 《Journal of Education & Work》2017,30(8):793-812

For a future faculty member the choice of which graduate programme and institution to attend is considered to have important implications for securing academic employment, developing skills to succeed in academia, and yielding positive returns on investment of time and money in education. Yet does it matter where a faculty member attends graduate school – and if so, is it the reputation of the programme or the institution that matters most for his or her labour market outcomes? In this study, we used nationally representative data from the U.S. to estimate the relationship between a faculty member’s graduate programme and institution and their institution of first academic employment, research productivity, and salary. Our findings suggest that the reputation of one’s graduate department may factor more heavily than reputation of institution in the type and level of institution at which he or she is first employed, while graduate institution reputation has notable marginal, positive benefits associated with research productivity and salary. We discuss implications for the influence of graduate education on academic careers.  相似文献
