In recent years, collaborative filtering, a recommendation algorithm that incorporates a user’s data such as interest, has received worldwide attention as an advanced learning support system. However, accurate recommendations along with a user’s interest cannot be ideal as an effective learning environment. This study aims to develop and evaluate an online English vocabulary learning system using collaborative filtering that allows learners to learn English vocabulary while expanding their interests. The online learning environment recommends English news articles using information obtained from other users with similar interests. The learner then studies these recommended articles as a method of learning English. The results of a two-month experiment that compared this system to an earlier collaborative filtering system called “GroupLens” reveal that learners who used the collaborative filtering system developed in this study read various news articles and had significantly higher scores on topic-specific vocabulary tests than did those who used the previous system. 相似文献

It is essential for medical students to learn and comprehend human anatomy in three dimensions (3D). With this in mind, a new system was designed in order to integrate anatomical dissections with diagnostic computed tomography (CT) radiology. Cadavers were scanned by CT scanners, and students then consulted the postmortem CT images during cadaver dissection to gain a better understanding of 3D human anatomy and diagnostic radiology. Students used handheld digital imaging and communications in medicine viewers at the bench‐side (OsiriX on iPod touch or iPad), which enabled “pixel‐to‐tissue” direct comparisons of CT images and cadavers. Students had lectures and workshops on diagnostic radiology, and they completed study assignments where they discussed findings in the anatomy laboratory compared with CT radiology findings. This teaching method for gross and radiological anatomy was used beginning in 2009, and it yielded strongly positive student perspectives and significant improvements in radiology skills in later clinical courses.

When conducting longitudinal research, the investigation of between-individual differences in patterns of within-individual change can provide important insights. In this article, we use simulation methods to investigate the performance of a model-based exploratory data mining technique—structural equation model trees (SEM trees; Brandmaier, Oertzen, McArdle, & Lindenberger, 2013)—as a tool for detecting population heterogeneity. We use a latent-change score model as a data generation model and manipulate the precision of the information provided by a covariate about the true latent profile as well as other factors, including sample size, under the possible influences of model misspecifications. Simulation results show that, compared with latent growth curve mixture models, SEM trees might be very sensitive to model misspecification in estimating the number of classes. This can be attributed to the lower statistical power in identifying classes, resulting from smaller differences of parameters prescribed by the template model between classes. 相似文献

Since the corporatization of national universities, the environment surrounding Japanese universities has dramatically changed in various respects. A series of government-led attempts have intended to support the domestic colleges and universities in gaining a competitive edge by improving the quality of teaching and research as well as guaranteeing the international validity of the country's higher education system. Impacts of all the challenges that have been tackled with internal efforts in the last few years could be enormous on the personnel workload. However, little is known about the impacts of Japan's recent university education reform, particularly on the changing workload of the faculty who engage at the forefront in student teaching and advising, administrative roles as well as research activities. Using results from individual faculty interviews, this paper attempts to link the changing workload of Japanese professors with specific reasons that are rooted in the country's recent university education reform. Reviewing the effects of the reform on faculty workload provides us with important insights for the long term and guides us to prevent the derailment from the endeavour to which a significant amount of resources have been dedicated by the country. 相似文献

Purpose: Maintenance and enhancement of vascular endothelial function contribute to the prevention of cardiovascular disease and prolong a healthy life expectancy. Given the reversible nature of vascular endothelial function, interventions to improve this function might prevent arteriosclerosis. Accordingly, we studied the effects of a 6-month static stretching intervention on vascular endothelial function (reactive hyperaemia peripheral arterial tonometry index: RH-PAT index) and arterial stiffness (brachial-ankle pulse wave velocity: baPWV) and investigated the reversibility of these effects after a 6-month detraining period following intervention completion. Methods: The study evaluated 22 healthy, non-smoking, premenopausal women aged ≥40 years. Subjects were randomly assigned to the full-intervention (n?=?11; mean age: 48.6?±?2.8 years) or a half-intervention that included a control period (n?=?11; mean age: 46.9?±?3.6 years). Results: Body flexibility and vascular endothelial function improved significantly after 3 months of static stretching. In addition to these improvements, arterial stiffness improved significantly after a 6-month intervention. However, after a 6-month detraining period, vascular endothelial function, flexibility, and arterial stiffness all returned to preintervention conditions, demonstrating the reversibility of the obtained effects. Conclusion: A 3-month static stretching intervention was found to improve vascular endothelial function, and an additional 3-month intervention also improved arterial stiffness. However, these effects were reversed by detraining. 相似文献

The Gilgen & Cho (1979a) Questionnaire to Measure Eastern and Western Thought was administered to 240 Japanese and 163 American respondents. Results indicate that significant differences exist between the two cultures. The Japanese reflect an Eastern thought mode while the Americans favor a Western one. Also, results indicate gender differences between cultures and within the American culture. American females are more Eastern thought inclined than are the males. 相似文献

Social style is investigated in terms of its two dimensions—assertiveness and responsiveness. Using the Assertiveness‐Responsiveness Scale, populations in Japan and the United States are compared to discover what differences, if any, might exist. Results indicate a significant difference between the two cultures. Also, the males in the two cultures tend to be more assertively inclined; the females more responsively. 相似文献
