This study examined whether a "goodness of fit" theoretical model, applied to families with and without children with learning disabilities, would be valuable in understanding the children's performance in school. A home interview was conducted with 63 families with a child with learning disabilities and 53 families with a comparable child without learning disabilities. The mothers were asked to rate how their own child fit into the family's expectations for children. It was found that, for both groups of families, children who were rated as a "poor fit" in the home demonstrated less positive behavior in the classroom and poorer achievement over the elementary school years. There was some evidence that poor fit in the home was even more negatively related to outcomes for children with learning disabilities. Discussion is centered on the importance of this theoretical model for understanding the importance of the home on successful school function. 相似文献

The need for excellent teachers to teach at-risk inner-city children is well documented. Too often new teachers who have received their field experience in the suburbs are hired to teach in multicultural inner-city schools with little preparation to serve this population of children and families. Changing the history of failure for this population of teachers and their students to an experience of success was the primary goal of the partnership between the Houston Independent School District and the University of Houston's College of Education.The structure of the Houston Teaching Academy (HTA) includes four collaborative decision-making councils. Representatives from the school and college serve on each of the councils. Shared weekly seminars for supervising teachers, student teachers, and college supervisors are led by school teachers or college supervisors. Methods courses are taught at the HTA, and the students serve as tutors in the classrooms. Several graduate college courses requested by teachers are offered at the HTA.Concurrent with the development of the HTA, a formative and summative evaluation has monitored the progress of the HTA toward its goals. The HTA graduates have been followed into their first years of teaching. Interviews with their principals indicate that 77% are effectively teaching in inner-city and multicultural settings. 相似文献

An innovative learning environment is the current outcome of the constructivist approach, the essence of which is co-construction of knowledge in an Information and Communication Technology (ICT) environment. We examined how Israeli students perceived 10 characteristics of their classroom learning environment—student cohesiveness, teacher support, involvement, task orientation, investigation, cooperation, equity, differentiation, computer usage and young adult ethos. Particular foci were students’ perceptions of the actual state of their learning environment compared with the preferred state, and which characteristics predicted students’ cooperation. Participants were 1022 students in 33 classes from 12 computerised elementary and middle schools in Israel. Data were collected using the Technology-Rich Outcomes-Focused Learning Environment Inventory (TROFLEI). Results indicated a gap between the actual and the preferred states for all characteristics, although the scope of these gaps differed between elementary-schools students and middle-school students for certain characteristics. Structural equation modelling (SEM) analysis indicated that nine characteristics of the innovative environment in both actual and preferred states were related to cooperation, with these relations being primarily direct with the exception of teacher support and differentiation which had an indirect influence. Teacher support was mediated through student cohesiveness, involvement, equity and young adult ethos, whereas differentiation was mediated through investigation. Evaluation of the innovative learning environment might lead to better insights regarding the behaviours and needs of twenty-first century students in Israel’s education system. These insights could advance constructivist processes and teaching methods and bring the students to effective cooperative learning in an innovative learning environment. 相似文献

In this article, we map the extent of educational inequality within Tasmania, and between Tasmania and the rest of Australia, using National Assessment Program—Literacy and Numeracy (NAPLAN) and senior secondary attainment data. This analysis yields some surprising findings, showing the success of Tasmanian primary and high schools and that Tasmanian educational inequality is most strongly expressed at the senior secondary level. We conclude that using such publicly available data to identify differential achievement within and between jurisdictions would strengthen public policy and practitioner interventions aimed at achieving more equal educational outcomes for students in all schools. Our findings also have implications for research directions in this field, suggesting that by analysis of NAPLAN and My School data across individual schools and jurisdictions academic researchers could assist practitioners gain a deeper understanding of inequalities reproduced by the systems they are working within, while finding examples of schools and systems which show a greater level of success in ameliorating disadvantage. 相似文献

It is expected that by 2003 continuous media will account for more than 50% of the data available on origin servers, this will provoke a significant change in Internet workload. Due to the high bandwidth requirements and the long-lived nature of digital video, streaming server loads and network bandwidths are proven to be major limiting factors. Aiming at the characteristics of broadband network in residential areas, this paper proposes a popularity-based server-proxy caching strategy for streaming media. According to a streaming media popularity on streaming server and proxy, this strategy caches the content of the streaming media partially or completely. The paper also proposes two formulas that calculate the popularity coefficient of a streaming media on server and proxy, and caching replacement policy. As expected, this strategy decreases the server load, reduces the traffic from streaming server to proxy, and improves client start-up latency. 相似文献

During the last decades, the education system has been marked by distinct processes of internationalisation. In the field of higher education, there are numerous and varied schools with different international profiles. This paper focuses on processes of internationalisation in the German sector of higher education. We contrast two higher secondary schools with international profiles: one international school in a West German metropolitan region with a long tradition and a younger internationally-profiled school located in the periphery of an East German urban centre. This institutional analysis presents school cultural similarities and differences with regard to different claims and concepts of internationality. This analysis is complemented by a reconstruction of three patterns of biographical meaning examining the internationality of pupils and their respective habitual fit to these internationally-profiled schools. We draw on qualitative data, consisting mainly of interviews with head teachers and pupils of these two schools. We argue that these differing regional forms of internationalisation indicate a stratification and hierarchisation in the field of higher education in Germany. 相似文献

Business educators are concerned with integrating diversity-related topics and seek methods by which to teach them. This paper suggests that as classes become more heterogeneous, the opportunity to examine diverse perspectives and experiences naturally arises in the course of class assignments and activities. The differential experiences of majorities and minorities are revealed when students discuss and write about their own experiences related to the content of various business courses. The issues of self and group identity and perceptions of others emerge in the context of small group discussions when students share their experiences as recorded in learning logs, personal cases, research assignments, and typical class discussions. The opportunity for community learning in heterogeneous groups provides a forum for diverse perspectives and experiences to be shared. Students and professors learn about different perceptions and reactions to personal and current events as well as their own perspectives, creating a culture of inclusion in the class. Implications and suggestions for a wider application of our methods to a global context are also offered. 相似文献

This paper presents modeling of Distribution STATCOM (D-STATCOM) in load flow calculations for the steady- state voltage compensation. An accurate model for D-STATCOM is derived to use in load flow calculations. The rating of this device as well as the direction of required reactive power injection for voltage compensation in the desired value (1 p.u.) is de- rived and discussed analytically and mathematically by the phasor diagram method. Furthermore, an efficient method for node and line identification used in load flow calculations is presented. The validity of the proposed model is examined by using two standard distribution systems consisting of 33 and 69 nodes, respectively. The best location of D-STATCOM for under voltage problem mitigation approach in the distribution networks is determined. The results validate the proposed model for D- STATCOM in large distribution systems. 相似文献
