The present study examines high school students with a prior history of grade retention (N = 38) compared to a matched control group of nonretained students. The retained students were lower on a number of scholastic variables (i.e., achievement, intelligence, grades), more often absent from school, and lower on three subscales of a self-esteem measure (the Self-Perception Profile for Adolescents). The authors explored the correlates of grade retained with the measured variables and found that the later a student was retained was associated with lower grades, less-positive school attitudes, less time on homework, lower educational expectations, more discipline problems, lower self-control, and a more external locus of control.  相似文献

When a crisis occurs in the school setting, school officials must be prepared to handle the situation effectively and efficiently. One of the ways school officials can handle a crisis situation is through the use of crisis intervention teams. The steps in establishing a crisis intervention team in a school setting include: determining goals, performing a needs assessment, finding model programs, developing a membership pool, developing a training program, preparing and maintaining a list of resources and plans for support services, establishing a communication network, designating a base of operations, planning team meetings, keeping records, and implementing the phases of debriefing. A crisis management scenario is presented and discussed in terms of the steps.  相似文献

This paper describes the roles of teachers and school psychologists and presents an overview of current and prospective methods of providing services to special needs children. On the basis of the literature and professional experience, it is suggested that changes are needed in the provision of special education services. The consultative relationship between teachers and school psychologists is viewed as the key to successful classroom intervention for special needs children. Although each profession brings expertise into the consultative relationship, better training is needed for teachers and school psychologists to ensure that effective intervention strategies are developed.  相似文献

Twenty fifteen marked the year of assessment for the Millennium Development Goals (MDGs). The MDGs that achieved the greatest success were those where evidence-based practice (EBP) interventions were implemented. The ability to practice evidence-based medicine is grounded in the creation of and access to medical literature that synthesizes research findings. The role that global health literature played in the success of the MDGs demonstrates that medical libraries and librarians have a role to play in achieving the Sustainable Development Goals (SDGs).Librarians can hold capacity-building workshops that provide instruction on how to access evidence-based literature and also train health professionals to conduct synthesis research. Research findings conducted by in-country health professionals are more likely to address issues being faced by local communities and will afford the possibility of obtaining the necessary evidence-based answers that can then be used to implement policies to resolve public health issues identified in the SDGs.This paper discusses how an international team of librarians leveraged funding from a Medical Library Association/Librarians without Borders/Elsevier Foundation/Research4Life grant to hold a capacity-building workshop in Zimbabwe and follow-up online trainings. The workshop focused on accessing evidence-based resources and conducting synthesis research. Outcomes included the creation and policy implementation of evidence-based knowledge products in alignment with local needs and galvanizing a multisectoral group of key individuals who have gone on to collaborate toward the vision of creating a Zimbabwe innovation hub. Looking ahead, such grants can be leveraged to conduct capacity-building to support knowledge translation and other local training needs.  相似文献

The National Committee on Science Education Standards and Assessment (1994 draft) viewed several science processes as important to an understanding of science as inquiry: formulating usable questions, planning experiments, conducting systematic observations, interpreting and analyzing data, drawing conclusions, communicating, and coordinating and implementing a full investigation. This study is one of three undertaken to develop research rubrics for a performance assessment of science processes and to evaluate seventh-grade science students' ability to perform them. Specifically, this article focuses on the processes of recording data, analyzing data, drawing conclusions, and providing evidence. A total of 364 students field tested the Alternative Assessment of Science Process Skills. Their responses were used to develop a research rubric, and then this rubric was used to determine response patterns that could inform both instruction and assessment of science process skills. Only 61% of students performed the activity and recorded data successfully. Sixty-nine percent of students did not attend to the hypothesis in drawing their conclusions. Eighty-one percent did not provide specific evidence for their conclusions. These results were discussed in light of relevant theories and models as well as their implications for instruction and assessment. © 1996 John Wiley & Sons, Inc.  相似文献

This article addresses the rhetoric of performance assessment with research on important claims about science performance assessments. We found the following: (a) Concepts and terminology used to refer to performance assessments often were not consistent within and across researchers, educators, and policy-makers. (b) Performance assessments are highly sensitive not only to the tasks and the occasions sampled, but also to the method (e.g., hands-on, computer simulation) used to measure performance. (c) Performance assessments do not necessarily tap higher-order thinking, especially when they are poorly designed. (d) Performance assessments are expensive to develop and use: technology is needed for developing these assessments in an efficient way. (e) Performance assessments do not necessarily have the expected positive impact on teachers' teaching and students' understanding. (f) If teachers are to use performance assessments in their classrooms, they need professional development to help them construct the necessary knowledge and skills. This article attempts to address some of these realities by presenting a conceptual framework that might guide the development and the evaluation of performance assessments, as well as steps that might be taken to create a performance assessment technology and develop teacher inservice programs. © 1996 John Wiley & Sons, Inc.  相似文献
