A model for book inquiry history analysis and book-acquisition recommendation of libraries     

Shih-Ting Yang  Ming-Chien Hung 《Library Collections, Acquisitions, and Technical Services》2012,36(3-4):127-142

In the era of knowledge economy, the libraries play an important role for library users to maintain and provide a large number of book resources. In order to satisfy requirements of borrowers, the libraries have to purchase all kinds of new books on a regular time schedule. However, the borrowers' demands cannot be satisfied simply because of the limited number of librarians and thus the libraries require useful suggestions for book-acquisition. Traditionally, the book-acquisition recommendation applications are collected by library consultants and then evaluated by librarians. Under the circumstance, several pitfalls (e.g., only partial library borrowers realize the book-acquisition recommendation procedure or a lot of time and human efforts required) might occur. Therefore, this paper focuses on the development of a book-acquisition recommendation model for libraries to acquire the various library borrowers' demands based on book inquiry history under a library system.In addition to the book-acquisition recommendation model, a Web-based book-acquisition recommendation system is also developed and a demonstration case is applied to verify the performance of the proposed approach. Under the book-acquisition recommendation platform, the librarians can automatically derive the book-acquisition recommendation list to fit borrowers' requirements and the complicated recommendation processes for borrowers can also be reduced. The attempt of this research is to enhance the accuracy and efficiency of book-acquisition performance and therefore the book-acquisition tasks in library can be efficiently accomplished.  相似文献   

Development of a personalized educational computer game based on students’ learning styles   总被引：1，自引：0，他引：1

In recent years, many researchers have been engaged in the development of educational computer games; however, previous studies have indicated that, without supportive models that take individual students?? learning needs or difficulties into consideration, students might only show temporary interest during the learning process, and their learning performance is often not as good as expected. Learning styles have been recognized as being an important human factor affecting students?? learning performance. Previous studies have shown that, by taking learning styles into account, learning systems can be of greater benefit to students owing to the provision of personalized learning content presentation that matches the information perceiving and processing styles of individuals. In this paper, a personalized game-based learning approach is proposed based on the sequential/global dimension of the learning style proposed by Felder and Silverman. To evaluate the effectiveness of the proposed approach, a role-playing game has been implemented based on the approach; moreover, an experiment has been conducted on an elementary school natural science course. From the experimental results, it is found that the personalized educational computer game not only promotes learning motivation, but also improves the learning achievements of the students.  相似文献   

The roles of a university professor in a teacher study group     

Hui-Chin Yeh  Hsiu-Ting Hung  Yi-Ping Chen 《Asia Pacific Education Review》2012,13(3):435-447

The opportunities in which university professors collaborate with the practicing school teachers in a teacher study group are few. This study investigated how a university professor facilitated a collaborative teacher study group to enhance teachers?? professional growth. Five primary school teachers and a university professor collaborated on incorporating Reader??s Theatre into the design and revision of the curriculum in a teacher study group. This study not only identified the roles of the university professor but also highlighted how this outside stimulus facilitated the process of teachers?? professional dialogues in this teacher study group. Five roles of the professor in the teacher study group were identified, including content expert, information provider, thought challenger, discussion facilitator, and caring listener. The discrepancies toward the roles that the professor in the teacher study group should serve between the elementary school teachers and the university professor were analyzed and reported. Implications were drawn for both classroom teachers and university professors.  相似文献   

Comparison of 3D reconstructive technologies used for morphometric research and the translation of knowledge using a decision matrix     

Charys M. Martin  Victoria A. Roach  Ngan Nguyen  Charles L. Rice  Timothy D. Wilson 《Anatomical sciences education》2013,6(6):393-403

The use of three‐dimensional (3D) models for education, pre‐operative assessment, presurgical planning, and measurement have become more prevalent. With the increase in prevalence of 3D models there has also been an increase in 3D reconstructive software programs that are used to create these models. These software programs differ in reconstruction concepts, operating system requirements, user features, cost, and no one program has emerged as the standard. The purpose of this study was to conduct a systematic comparison of three widely available 3D reconstructive software programs, Amira^®, OsiriX, and Mimics^®, with respect to the software's ability to be used in two broad themes: morphometric research and education to translate morphological knowledge. Cost, system requirements, and inherent features of each program were compared. A novel concept selection tool, a decision matrix, was used to objectify comparisons of usability of the interface, quality of the output, and efficiency of the tools. Findings indicate that Mimics was the best‐suited program for construction of 3D anatomical models and morphometric analysis, but for creating a learning tool the results were less clear. OsiriX was very user‐friendly; however, it had limited capabilities. Conversely, although Amira had endless potential and could create complex dynamic videos, it had a challenging interface. These results provide a resource for morphometric researchers and educators to assist the selection of appropriate reconstruction programs when starting a new 3D modeling project.

Conceptual Understanding of Causal Reasoning in Physics     

Woei Hung  David H. Jonassen 《International Journal of Science Education》2013,35(13):1601-1621

College students often experience difficulties in solving physics problems. These difficulties largely result from a lack of conceptual understanding of the topic. The processes of conceptual learning reflect the nature of the causal reasoning process. Two major causal reasoning methods are the covariational and the mechanism‐based approaches. This study was to investigate the effects of different causal reasoning methods on facilitating students’ conceptual understanding of physics. 125 college students from an introduction physics class were assigned into covariational group, mechanism‐based group, and control group. The results show that the mechanism‐based group significantly outperformed the other two groups in solving conceptual problems. However, no significant difference was found in all three groups performance on solving computational problems. Speculation on the inconsistent performance of the mechanism‐based group in conceptual and computational problem solving is given. Detailed analyses of the results, findings, and educational implications are discussed  相似文献

Family,schools and Taiwanese children's outcomes     

Chih-Lun Hung 《Educational research; a review for teachers and all concerned with progress in education》2013,55(2):115-125

Background Educational reform is a major challenge facing schools in Taiwan. The new educational reform requires that every primary school must have parental involvement programmes in their school schedules, and to support these new programmes, there is a need for research to examine the extent and nature of parental involvement in primary schools in Taiwan, and to investigate the impact of parental involvement on pupil outcomes.

Purpose The purpose of the study was to examine the extent to which parents' involvement in schooling is related to primary pupil outcomes, after taking into account differences in family social status and family structure, and the children's perceptions of their school learning environments.

Sample For the analyses data were collected in 2001 from 261 6th-grade Taiwanese students, 128 boys and 133 girls, from four primary schools in the Taichung City school district. The average age of the children was approximately 11 years.

Design and methods In the analysis of the research model, a quantitative approach was adopted, in which each student completed two questionnaires and two academic achievement tests. The first questionnaire included questions to assess family social status, family structure and parents' involvement in their children's education. In the second questionnaire there were questions to measure pupils' self-concept and perceptions of their schools' learning environments. The data were analysed using multiple-regression techniques to examine relationships among family social status, family structure, parental involvement, the school learning environment and pupils' school-related outcomes.

Results The findings suggested that: (a) children's academic achievement is related to their family social status and perceptions of immediate family learning environments, and (b) children's self-concept is associated with their perceptions of classroom learning environments, parents' aspirations and parents' involvement at home. These propositions indicate the differential nature of the relationships among family and school environments and measures of children's school outcomes.

Conclusions In the Taiwanese context, by showing the particularly important association between Taiwanese family environments and children's school outcomes, the present investigation supports the educational reform movement that encourages schools to involve parents more intimately in shared responsibilities.  相似文献

Micromixer based on viscoelastic flow instability at low Reynolds number   总被引：1，自引：0，他引：1  

Y. C. Lam  H. Y. Gan  N. T. Nguyen    H. Lie 《Biomicrofluidics》2009,3(1)

We exploited the viscoelasticity of biocompatible dilute polymeric solutions, namely, dilute poly(ethylene oxide) solutions, to significantly enhance mixing in microfluidic devices at a very small Reynolds number, i.e., Re≈0.023, but large Peclet and elasticity numbers. With an abrupt contraction microgeometry (8:1 contraction ratio), two different dilute poly(ethylene oxide) solutions were successfully mixed with a short flow length at a relatively fast mixing time of <10 μs. Microparticle image velocimetry was employed in our investigations to characterize the flow fields. The increase in velocity fluctuation with an increase in flow rate and Deborah number indicates the increase in viscoelastic flow instability. Mixing efficiency was characterized by fluorescent concentration measurements. Our results showed that enhanced mixing can be achieved through viscoelastic flow instability under situations where molecular-diffusion and inertia effects are negligible. This approach bypasses the laminar flow limitation, usually associated with a low Reynolds number, which is not conducive to mixing.  相似文献
