The primary purpose of this Delphi study was to determine which of the research-identified differentiated instructional elements are the most effective for improving student performance as perceived by secondary principals in 2A to 5A 2009 ―Exemplary‖ public high schools in Texas. A secondary purpose for this study was to determine what additional differentiated instructional elements are perceived by this study‘s targeted principals as being critical for student success. The researcher obtained feedback during three Delphi survey rounds from the twenty-four member expert panel regarding which of the research-identified differentiated instructional elements they perceived to be the most effective for improving student performance. The differentiated instructional elements presented in the survey were based upon a sound theoretical framework resulting from a review of existing research on differentiated instruction. After Round Three, consensus was reached, and the data collection period ended. Each of the surveys for the study, as well as the statistical analysis, can be found in the appendices of this dissertation. The findings of this study determined that using a variety of resources, as well as a variety of strategies, were the top-ranked research-identified differentiated instructional elements that the expert panel perceived to be the most effective for improving student performance. In addition, panelists agreed that the differentiated instructional elements already identified in existing research, as presented in this study, are comprehensive and sufficient for improving student performance. Without a doubt, the conclusions and recommendations of this study could extend the current knowledge base by promoting the use of the most effective research-identified differentiated instructional elements to improve student performance. Furthermore, the implications of the study will be invaluable for ongoing professional development, principal and teacher preparation programs, and for those in the field seeking to improve their daily educational practices for student impact.

Differentiated-Service networks is designed for solving scalability problems through traffic aggregation. However, it can't guarantee end-to-end QoS of individual flow. In this thesis, we propose a Self-Adaptive Control Scheme for Differentiated-Service networks that can improve the throughput of individual flows dynamically. In this scheme, egress routers monitor the average throughput of individual flow, and send the Self-Adaptive Control Messages to ingress routers if need. The ingress router re-allocate network resources to improve throughput of high-priority flows depending on the Control Messages. We use NS-2 simulator to prove that our scheme that can improve throughput of high-priority flows dynamically, and suggest that a better time interval of Self-Adaptive control can be determined based on the queue sizes, packets arrival rate and departure rate. Finally, we use Random Early Detection (RED) queue instead of Drop-Tail queue to reduce unfairness of individual flows when there are congestion and insufficient network resources.

<p>The purpose of this essay is to find out how upper secondary English teachers should work in order to reach the weaker students. I am interested in what has been written about mixed-ability classes, the challenges they present and most of all how teachers of English need to work in such classes to reach all students, especially the weaker ones.</p><p>I have also interviewed three upper secondary teachers about how they work to reach the weaker students in their classes.</p><p>My findings are that, according to the teachers interviewed, the best way to deal with the problem is to bring back ability grouping. The literature I read mostly had negative views on this method and stressed the importance of differentiation and motivation instead. Both the literature and the teachers claimed that a good atmosphere, clear instructions, structure and setting routines were the most important factors when working with mixed ability classes.</p>

The purpose of this study was to discover and describe how two teachers effectively interacted with and differentiated instruction for students who displayed off-task behaviors in the classroom. Through the use of observations and interviews, I described how two teachers interacted with students who display high-frequency, low-intensity off-task behaviors; identified strategies these effective teachers used in dealing with these behaviors; described where the teachers’ behaviours, attitudes, and practices lay on the Preventive-Restorative (P-R) continuum of beliefs of inclusion; and discovered how the teachers’ self-efficacy is related to P-R orientations and effective teaching behaviors. The teachers were chosen based on their principals’ belief in their effectiveness in dealing with off-task behaviours. The principal and the teacher collaboratively chose the students who displayed off-task behaviours on a consistent basis. The findings of this study confirm the existing research; the two teachers, whose beliefs lay on the preventive end of the continuum of beliefs of inclusion, tended to use effective teaching practices; these beliefs and practices were related to the teachers’ beliefs of their capability in being able to effectively help their students; these two teachers, who have preventive beliefs and high efficacy beliefs, interact in ways that are beneficial to students who display off-task behaviours. The common themes that emerged through the analysis of both teachers’ data included the belief in and the use of differentiated instruction; the belief in the importance of having a positive classroom environment; the practice of ensuring student engagement; the teachers’ use of their knowledge about students; and the teachers’ beliefs about inclusion and efficacy beliefs. The diversity of the teachers and their classroom contexts resulted in some differences in the findings, which are also discussed. This research extends previous research about teachers’ beliefs about inclusion and efficacy beliefs to teaching practices used for and interactions with students who display off-task behaviours. The findings also extend previous research revealing a relationship between teachers’ beliefs about inclusion and the belief in the importance of creating a positive classroom environment. Implications of this research for practice and for future research are discussed. / Thesis (Master, Education) -- Queen's University, 2010-08-26 09:43:54.336

Bakalauro baigiamajame darbe analizuojamas ikimokyklinio amžiaus vaikų socialinių įgūdžių ugdymas Radviliškio vaikų lopšelyje – darželyje. Tyrimui atlikti pasirinkta neatsitiktinė, netikimybinė tikslinė informantų – vaikų lopšelio –darželio auklėtojų bei priešmokyklinės grupės pedagogų – imtis.

Climate change is the greatest environmental international problem facing the world today. This paper begins with a review of the climate change regime to date showing the mistakes that were made leading to failure in Copenhagen. It looks at China’s unique position in the international community and concludes that a meaningful climate change solution is not possible without China’s participation. It examines the concepts of CBDR and fairness to determine whether it is fair for the world to demand China’s participation. It looks at characteristics which should be present in a fair climate change solution, and concludes with a brief look at international trade law to determine what alternatives would be available to a coalition of willing states to encourage China’s participation in a global solution or, in a worst case scenario, to form an effective solution without China’s willing participation.
