From observing 26 precocious preschoolers during free play, it was determined that they engaged in high frequencies of associative and dramatic play. The girls engaged in more cooperative and less solitary play than the boys. The older children participated in more solitary, parallel, and less cooperative and less dramatic play than their younger peers. The higher IQ group (median IQ = 160+) undertook less constructive and more dramatic play than the lower IQ group (median IQ = 137). 相似文献

The exponential growth and sophistication of new information and computer technology (ICT) have greatly influenced human interactions and provided new metaphors for understanding the world. The acceptance and integration of ICT into social work field education are examined here using the technological acceptance model. This article also explores potential challenges regarding the adoption of ICT into social work field practica. The article concludes with implications for adopting and integrating ICTs in social work field education. 相似文献

This paper looks at the sensitivity of thickness to variation of friction. The models of friction used are: the classic Amontons-Coulomb; a nonlinear pressure-dependent model proposed by Wriggers, vu Van and Stein; and a velocity-dependent model proposed by Molinari, Estrin and Mercier. They are coded in FORTRAN for use with finite element program ABAQUS. The contact problem is then formulated in the total Lagrangian formulation for contact between an elastic-plastic body and rigid tools. The variational (weak) form of the formulation is given and this is discretized by finite element method. To test and compare the models, one common metal forming processes is simulated: deep drawing of a square-cup. The sensitivity graphs showing each of the three friction models together is given at the end. One other conclusion although not major part of this work is that Amonton-Coulomb is not the best model suited for contact conditions in metal forming processes, because Wriggers et al. model and Molinari et al. model provide better results for modelling bends and corners. 相似文献

To academic visionaries the new century appears to have an emerging environment characterized by increased complexity, uncertainty,
unpredictability which, some have argued, render traditional notions of planning and management irrelevant. The expectations
of management and planning scholars carry the implicit assumption that somehow individual capability and organizational capacities
will rise to meet the enormous challenges of this new environment. In the light of this situation the purposes of this paper
are: (1) to briefly examine the limitations and criticisms of traditional educational planning; (2) to outline the emerging
concepts and processes which collectively form a new paradigm for strategic planning; (3) to discuss the new model within
the context of changing national policy and planning environments and increased localization; (4) to review the limited results
of empirical research related to more participatory planning models; and (5) to offer a critique of the assumptions and practicality
of the new model in the process of planning and sustaining educational change in developing countries 相似文献

Previous research on conceptions of teaching comes from three distinct areas. The first is based on interviews with students and staff in higher education, the second involves the investigation of the conceptions and beliefs of schoolteachers, while the third derives from more general consideration of the nature of conceptions themselves. The empirical study reported here drew on these differing research areas to distinguish between beliefs and conceptions about good teaching and to explore their possible origins. The data came from student teachers, but the findings contribute to current thinking about conceptions of teaching in higher education. Bringing the empirical findings together with the three areas of previous research enables a more complete concept map to be drawn to summarise what may underlie the notion of “good teaching”. 相似文献

The Indiana Project on Academic Success and the College Board Pilot Study on Student Retention evaluated the effectiveness of a variety of approaches to student retention. The authors share empirically grounded insights gleaned from this research. 相似文献
