This study examines young children's number sense in subjects from Finland (n=254), Hong Kong (n=246), and Singapore (n=130). Chinese, English and Finnish versions of the Early Numeracy Test (ENT; Van Luit et al., 1994) were used. Two highly correlated aspects of number sense were measured, one reflecting children's abilities to organize and compare quantities (i.e. relational skills), and the other pertaining to their ability to operate with number-word sequence (i.e. counting skills). The results showed significant age-related gain on the relational and counting scales. No gender or language differences were found. The children in Hong Kong and Singapore outperformed those in Finland in relational and counting tasks starting at the age of four years. The children in Singapore also had better relational and counting skills than those in Hong Kong. Differences in teaching were assumed to explain the findings. 相似文献

Quality issues in the internationalisation of higher education 总被引:5,自引:0,他引:5
Dirk Van Damme 《Higher Education》2001,41(4):415-441
Although the quality issue has become a central preoccupation inother domains of higher education, current internationalisation policiesand practices in higher education have developed without much concernfor quality assurance. The central thesis of this paper is that we havecome to a point in the development of higher education whereinternationalisation policies and practices face the limits of theirdevelopment unless the quality challenge is addressed in all itsconsequences. The paper first provides an overview of contemporary formsof and recent developments in internationalisation in higher education.From more or less `traditional' forms such as student and teaching staffmobility, internationalisation policies and practices nowadays move intoactivities such as exporting higher education via branch campuses andinstitutional co-operation, developing transnational university networksand virtual delivery of higher education, and the harmonisation ofhigher education systems. In these recent developments several issuesand challenges arise, which in one kind or another have direct links tothe quality challenge. The quality of internationalisation policies andpractices itself is an important problem, but of more importance are theissues of the recognition of foreign diplomas and degrees and therecognition of credits and credit-transfer. This paper takes a criticalstance towards for example the ECTS, which tries to solve these issueswithout much concern for quality. The way out lies in an integration ofinternationalisation policies and general quality assurance practices atinstitutional and policy levels. 相似文献

The authors describe a sexual education program that was aired by the campus radio station at Kansas State University. Use of college radio to promote student health issues is first reviewed. Specific program content and production obstacles are then discussed. Recommendations for future shows are made. 相似文献

Cooperative play was investigated by a controlled pre/post-test intervention design with 28 dyads of 6-year-old students developmentally at-risk. Selection was based upon cut-off scores on a language development test and a nonverbal IQ test, and same-sex pairs were matched within classrooms. Co-variables were: socio economic status, free play time in school and pedagogical quality of the classrooms. Each child was rated with respect to temperament. Play session 1 served as pretest for both research conditions. Then five play sessions of 20 min within 3 weeks took place in the experimental condition. Eight weeks after session 6 a play session took place in both research conditions serving as post-test. After microgenetic analyses of the data, ANCOVA's were computed of time played in collaboration, and proportion of pretend play and of deep collaboration. The results revealed that the level of collaboration had improved dramatically in the experimental condition only. Moreover, the findings showed that the length of time dyads spent cooperating, and how deeply they collaborated on tasks, was related to how agreeable and emotionally stable they were. Gender effects also came forward. No long-term intervention effects were found. 相似文献

In this paper, a robust fault tolerant control, which provides a global fixed-time stability, is proposed for robot manipulators. This approach is constructed based on an integration between a fixed-time second-order sliding mode observer (FxTSOSMO) and a fixed-time sliding mode control (FxTSMC) design strategy. First, the FxTSOSMO is developed to estimate the lumped disturbance with a fixed-time convergence. Then, based on the obtained disturbance estimation, the FxTSMC is developed based on a fixed-time sliding surface and a fixed-time reaching strategy to form a global fixed-time convergence of the system. The proposed approach is then applied for fault tolerant control of a PUMA560 robot and compared with other state-of-the-art controllers. The simulation results verify the outstanding fault estimation and fault accommodation capability of the proposed fault diagnosis observer and fault tolerant strategy, respectively. 相似文献

In this study, methods for data acquisition, analysis, modelling, and simulation of performance parameters in road cycling on real tracks were developed and evaluated. A simulator was designed to facilitate the measurement in a laboratory environment. The simulation included real height profiles and a video playback that was synchronised with the cyclist’s current virtual position on the track, and online visualisation of course and performance parameters. Field data obtained on mountain tracks in this study were compared with the state-of-the-art mathematical model for road cycling power, established by Martin et al. (J Appl Biomech 14: 276–291, 1998), which accounts for the gradient force, air resistance, rolling resistance, frictional losses in wheel bearings and inertia. The model described the performance parameters accurately with correlation coefficients of 0.96–0.99 and signal-to-noise ratios of 19.7–23.9 dB. It was shown that the mathematical model could be implemented on an ergometer for simulating rides on real courses, providing similar quality measures when comparing field and simulator measurements. 相似文献
