Since their inception, charter schools have been a lighting rod for controversy, with much of the debate revolving around their effectiveness in improving student achievement. Previous research has shown mixed results for student achievement; this could be the consequence of different policy environments or varying methodological approaches with differing assumptions across studies. In our analysis, we discuss these approaches and their assumptions and estimate charter school achievement effects using a consistent methodology across seven locations. 相似文献

This study aimed to investigate the causal pathways and factors associated with being involved in bullying behaviour as a bully-victim using longitudinal data from students aged 11–14 years over the transition time from primary to secondary school. Examination of bully-victim pathways suggest a critical time to intervene is prior to transition from the end of primary school to the beginning of secondary school to prevent and reduce the harm from bullying. Negative outcome expectancies from bullying perpetration were a significant predictor of being a bully-victim at the end of the first year of secondary school. The findings show an association between peer support, connectedness to school, pro-victim attitudes, outcome expectancies and level of bullying involvement. Implications for intervention programs are discussed. 相似文献

The University of Wollongong (UOW) in New South Wales, Australia, has undertaken an innovative and collaborative research project to demonstrate the value that can be provided by academic libraries through a tool called the “library cube”. The library cube consists of two major components: a backend system containing a multidimensional data warehouse linking student borrowing and use of electronic resources to students' academic marks (grades); and a frontend system that allows users to quickly and easily create cross tabulated data views, such as average student marks by frequency of library resource usage and gender. The project is different from the efforts of other institutions to link usage to student outcomes, in that the library cube is not an isolated research project, but is now an ongoing part of UOW's systems and performance reporting. The library cube represents a fundamental shift in evaluating the student experience through the integration of discrete systems and datasets. It has revealed a very strong relationship between student library usage and academic performance. This information will improve UOW library's ability to demonstrate value to clients and stakeholders. The library cube has also delivered some anticipated and unexpected findings on the relationship between social variables, such as gender, age, and citizenship, and library usage behaviors; and in doing so has also identified potential target audiences for library promotions and engagement strategies. 相似文献

Undergraduates entering science curricula differ greatly in individual starting points and learning needs. The fast pace, high enrollment, and high stakes of introductory science courses, however, limit students' opportunities to self-assess and modify learning strategies. The University of Washington's Biology Fellows Program (BFP) intervenes through a 20-session, premajors course that introduces students to the rigor expected of bioscience majors and assists their development as science learners. This study uses quantitative and qualitative approaches to assess whether the 2007-2009 BFP achieved its desired short- and long-term impacts on student learning. Adjusting for differences in students' high school grade point average and Scholastic Aptitude Test scores, we found that participation in the BFP was associated with higher grades in two subsequent gateway biology courses, across multiple quarters and instructors. Two to 4 yr after participating in the program, students attributed changes in how they approached learning science to BFP participation. They reported having learned to "think like a scientist" and to value active-learning strategies and learning communities. In addition, they reported having developed a sense of belonging in bioscience communities. The achievement of long-term impacts for a short-term instructional investment suggests a practical means to prepare diverse students for the rigors of science curricula. 相似文献

Students of Project Adapt (PA), an instructional program for at-risk middle school students in Brooklyn NY, have displayed startling improvement on cognitive outcome measures. Teacher given grades and standardized tests illuminate the progress students have made since entering the program. The current investigation attempts to analyze PA on students' affective responses in a pre/post-test experimental design. Upon entering PA, students completed measures of interest, affect, and their previous teachers' behavior (pre). These ratings were then compared to end of year ratings on the same instruments (post). Results indicate students' perceive PA teachers utilizing different behaviors than their previous teachers. Additionally, student affect and interest increased significantly. Results of this study have implications for both instructional researchers and educational practitioners. 相似文献

Confirmatory factor analytic procedures are routinely implemented to provide evidence of measurement invariance. Current lines of research focus on the accuracy of common analytic steps used in confirmatory factor analysis for invariance testing. However, the few studies that have examined this procedure have done so with perfectly or near perfectly fitting models. In the present study, the authors examined procedures for detecting simulated test structure differences across groups under model misspecification conditions. In particular, they manipulated sample size, number of factors, number of indicators per factor, percentage of a lack of invariance, and model misspecification. Model misspecification was introduced at the factor loading level. They evaluated three criteria for detection of invariance, including the chi-square difference test, the difference in comparative fit index values, and the combination of the two. Results indicate that misspecification was associated with elevated Type I error rates in measurement invariance testing. 相似文献

This study aimed to examine the written arguments developed by college freshman students using the Science Writing Heuristic approach in inquiry-based general chemistry laboratory classrooms and its relationships with students’ achievement in chemistry courses. Fourteen freshman students participated in the first year of the study while 19 freshman students participated in the second year of the study. Two frameworks, an analytical and a holistic argument framework, were developed to evaluate the written argument generated by students. The analytical framework scored each argument component separately and allocated a Total Argument score while the holistic framework evaluated the arguments holistically. Three hundred and sixty-eight samples from 33 students were evaluated. Stepwise regression analyses revealed that the evidence and the claims–evidence relationship components were identified as the most important predictors of the Total Argument and the Holistic Argument scores. Students’ argument scores were positively correlated with their achievement, as measured by the final grade received for the general chemistry laboratory and the general chemistry lecture course. 相似文献

Increasing numbers of schools and districts have expressed interest in interim assessment systems to prepare for summative assessments and to improve teaching and learning. However, with so many commercial interim assessments available, schools and districts are struggling to determine which interim assessment is most appropriate to their needs. Unfortunately, there is little research-based guidance to help schools and districts to make the right choice about how to spend their money. Because we realize the urgency of developing criteria that can describe or evaluate the quality of interim assessments, this article presents the results of an initial attempt to create an instrument that school and district educators could use to evaluate the quality and usefulness of the interim assessment. The instrument is designed for use by state and district leaders to help them select an appropriate interim assessment system for their needs, but it could also be used by test vendors looking to evaluate and improve their own systems and by researchers engaged in studies of interim assessment use. 相似文献

In this study, First Nation community members in Canada’s Yukon Territory share their stories about teaching and learning, both in informal and formal settings, in an effort to identify practices that might serve teachers to be more responsive to their First Nation students. In all, 52 community members between the ages of 15 and 82 shared their stories and assisted in identifying eight categories of practice and thought associated with effective teaching practices for this First Nation. Based upon these categories of thought and practice, we present a pedagogical framework for teachers and, finally, illustrate how this profile and the stories about teaching and learning are being used for adjusting and improving teaching practice in this First Nation. 相似文献
