Homework (HW) is one of the most common school-related activities among parents, students and teachers. However, the need to assign HW to students has been extensively debated. The present investigation examines the relationship between specific HW variables (i.e. amount of HW completed, time spent on HW and perceived quality of HW time management) and academic achievement, while controlling for students’ gender and grade level. Participants included 454 students (ranging from 10 to 16?years of age) from three schools in northern Spain. A multivariate analyses of variance and path analyses showed that the amount of HW completed decreased with increased schooling, as did students’ perceived quality of HW time management. Data from hierarchical regression analyses completed by path analyses provided evidence that time spent on HW conjointly with perceived quality of HW time management explains how academic achievement is mediated by the amount of HW completed. These findings deepen the understanding of the complex impact of time spent on HW and on academic achievement.  相似文献

The use of Web 2.0 technologies for knowledge management is invading the corporate sphere. The Web 2.0 is the most adopted knowledge transfer tool within knowledge intensive firms and is starting to be used for mentoring. This paper presents IM-TAG, a Web 2.0 tool, based on semantic technologies, for informal mentoring. The tool offers recommendations of mentoring contents built upon personal competencies of the mentee, combined with content and opinion tagging. To validate the tool, a case study comparing recommendations from the IM-TAG and a group of experts was conducted. Results show that the accuracy of IM-TAG's recommendations is notable and satisfactory. The main conclusions of this research may be valuable to organizations immersed in mentoring programs.  相似文献

This paper extends previous studies on knowledge management by analysing factors affecting Web Knowledge Sharing (WKS) in small- and medium-sized enterprises (SMEs). In addition, the impact of WKS on organizational innovation and the moderating effect of IT skills on this relation are analysed. Grounded in the technology-organization-environment (TOE) theory and the resource-based view (RBV), this paper develops an integrative research model, which analyses these relations using structural equation modelling on a data set of 535 Spanish SMEs. Results suggest that technological and organizational factors – IT expertise and commitment-based human resources practices – positively influence WKS, while the contrary is found for environmental factors (customer power). In addition, results show that WKS contributes positively to organizational innovation, though support for the moderating effect of IT skills in this relation is not found. The main conclusions of this research can be valuable to SMEs that use or intend to use Internet technologies for knowledge management.  相似文献

The aim of this study was to determine which physiological variables predict excellence in middle- and long-distance runners. Forty middle-distance runners (age 23 ± 4 years, body mass 67.2 ± 5.9 kg, stature 1.80 ± 0.05 m, VO(2max) 65.9 ± 4.5 ml · kg(-1) · min(-1)) and 32 long-distance runners (age 25 ± 4 years, body mass 59.8 ± 5.1 kg, stature 1.73 ± 0.06 m, VO(2max) 71.6 ± 5.0 ml · kg(-1) · min(-1)) competing at international standard performed an incremental running test to exhaustion. Expired gas analysis was performed breath-by-breath and maximum oxygen uptake (VO(2max)) and two ventilatory thresholds (VT(1) and VT(2)) were calculated. Long-distance runners presented a higher VO(2max) than middle-distance runners when expressed relative to body mass (P < 0.001, d = 1.18, 95% CI [0.68, 1.68]). At the intensities corresponding to VT(1) and VT(2), long-distance runners showed higher values for VO(2) expressed relative to body mass or %VO(2max), speed and oxygen cost of running (P < 0.05). When oxygen uptake was adjusted for body mass, differences between groups were consistent. Logistic binary regression analysis showed that VO(2max) (expressed as l · min(-1) and ml · kg(-1) · min(-1)), VO(2VT2) (expressed as ml · kg(-0.94) · min(-1)), and speed at VT(2) (v(VT2)) categorized long-distance runners. In addition, the multivariate model correctly classified 84.7% of the athletes. Thus, VO(2max), VO(2VT2), and v(VT2) discriminate between elite middle-distance and long-distance runners.  相似文献

The purpose of the present study was to investigate the socio-demographic and lifestyle determinants of physical activity practice, as well as the motivations for being or not being physically active in Spanish university students. A representative sample of students from a Spanish university (n = 2,051; 42.1% males; mean age 21.9, s = 4.8 years) participated in the present cross-sectional study. A questionnaire including questions regarding lifestyle, dietary habits, parents' characteristics, and physical activity habits was administered to the students. The socio-demographic and lifestyle determinants of physical activity practice were assessed using multivariable logistic regression. 68.4% of men and 48.4% of women reported to practise physical activity in the present sample. Those who practised physical activity consumed more fruits and were less likely to be smokers compared to non-physically active students. Also, physically inactive men spent more time in front of the computer and physically inactive women spent more time in front of the TV and were more likely to be frequent alcohol consumers. Maternal educational level and maternal physical activity habits were also important determinants of physical activity practice among men and women respectively. In conclusion, physically active students tended to engage in other healthy habits in the present population, suggesting the clustering of healthy or unhealthy lifestyle factors among specific subgroups.  相似文献

ABSTRACT

Inclusive education of disabled students has been promoted in European disability policies. However, the transition process from more segregated system is slow. The purpose of this study was to provide an insight about different types of schooling of disabled children affected by a rare disease across Europe and to evaluate their and caregivers’ well-being. We analysed data from a cross-sectional study (BURQOL-RD) of persons with rare diseases that cause intellectual and/or physical disability: Prader-Willi syndrome, fragile X syndrome, three types of mucopolysaccharidosis and Duchenne muscular dystrophy. The sample consisted of 359 children aged 6–17 and 269 caregivers from eight European countries. Results showed differences between countries in proportion of students placed in special schools, which are still valid option in countries such as Germany, France or UK. Within the inclusive education modalities, lack of special support for disabled students was observed especially in low-income countries. No association between the type of schooling and quality of life was observed, but the subjective caregivers’ burden seems to be higher in special schools. The study shows existent differences in implementation of inclusive education in Europe. More research is needed in the field of rare disease disability and educational needs.  相似文献

Policy responses to disparities in education have proven to be largely inadequate in reducing persistent differences in academic outcomes, commonly referred to as the achievement gap. In this article, we identify some of the ways in which the fragmented nature of public policy generally, and education policy specifically, has contributed to the problem. We draw upon research from a variety of disciplines to argue that the most effective way to address the broad array of social and economic conditions impacting low-income children and their families is through the adoption of an ecological approach, similar to those used in public health. In order for education policies to promote equity in academic outcomes, they must explicitly address the ways in which race, class, language, and culture, as well as implementation processes, reproduce and reinforce disparities in academic achievement. We propose a new, comprehensive framework for equity-based education policy that makes it possible to respond to the social and economic factors that impact, and often undermine, efforts to improve academic outcomes. An analysis of California’s Local Control Funding Formula (LCFF) and interviews with senior county leaders allows the authors to draw connections to the new policy framework, generating recommendations for strengthening education policies like LCFF.  相似文献
