In order to understand how children's beliefs and cognitive performance vary according to development in their conceptions of effort and ability, 120 fourth and sixth graders were given the following assessments: (a) a measure of agency beliefs, defined as the extent to which persons believe they have access to certain classes of potential means, including effort, ability, powerful others, and luck; (b) a battery of intelligence test scales, including figural patterns, letter series, arithmetic, and spelling; (c) an interview designed to assess developmental levels in conceptions of effort and ability. Correlations between intelligence scores and agency beliefs for effort decreased with increasing levels of reasoning about effort and ability, but correlations between intelligence scores and agency beliefs for ability increased with increasing levels of reasoning. No such trends were found in correlations between performance and agency beliefs for luck or for unknown causes. The results are discussed in terms of the interaction between individual differences and developmental change. 相似文献

This study explores teachers’ first enactments of a set of theory-based curriculum materials designed to support academic language instruction. Specifically, this multiple case study looks at how six middle school English teachers in three US schools adapted the materials; each case includes a pair of teachers, one novice and one more experienced. All schools were located in the same district where a school performance measurement system was being used to publicly rank schools’ academic performance and growth. Multiple measures were used to look for evidence of adaptations and why teachers made adaptations. We found that all teachers adapted the curriculum, most often in response to either perceived student needs or district reform pressures. In two cases, patterns of adaptation differed by teacher experience; experienced teachers appeared better able to adapt curriculum materials to meet instructional goals. This pattern did not hold up at the third school, where teachers faced greater reform pressures. Taken together, these findings suggest that researchers should pay more attention to the role of school and district policy on teachers’ enactments of theory-based reforms. We conclude with guidance to researchers, instructional leaders and others interested in the potential of theory-based curricula as a lever for improving classroom instruction. 相似文献

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

Interest in the potential benefits of providing tablet computers to students has grown in recent years, both in UK institutions, and across the world. Limited research studies have been reported in higher education (HE), and primary and secondary school settings, tentatively suggesting a range of positive impacts on learners, but little conclusive research has been published on the introduction of tablets in further education (FE). This article presents a case study of a single, mid-size English FE college, which piloted the provision of tablets to bounded groups of students and teachers in four diverse curriculum areas. The author was invited to help design the college’s evaluation of the pilot, which would inform a potential business case to extend the pilot to all students. One element was a qualitative research project, with data captured through a series of focus group interviews with all 64 students who received tablets, and separate interviews with their ten teachers. Findings are reported here, exploring the extent to which students and teachers perceived learning benefits from the tablets: for some learners, this was reported as enhancing the organisation of learning; supporting greater independence of learning and enabling more purposive learning. Barriers to learning enhancement were also identified, including institutional issues (frustration with technical infrastructure), and individual learner disengagement (distraction and surface engagement with mere ‘novelty’). Concluding that the tablets’ clear benefits were not automatically transformative, and engagement was not uniform, findings are relevant to FE managers and leaders of other institutions considering tablets as a possible learning panacea. 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

Culture has featured prominently in minority educational research, policies, and intervention since the early 1960s. It is
receiving even more attention today in minority education discourse due to the emergence of cultural diversity and multicultural
education as popular national issues. A careful analysis of the new discourse suggests, however, that the issue has shifted
from how cultural differences enhance or deter the school adjustment and academic performance of minority children to the
problem of cultural hegemony and representation in school curriculum and other domains of education. But cultural diversity
and multicultural education are only a partial solution to the problems of culture in minority education. This essay is in
two parts. In part one I argue for a reconsideration of the earlier question about how culture affects minority school adjustment
and academic performance. I also proposecultural frame of reference as a new level of analysis of the cultural problems that confront minority students at school. In part two I illustrate my
points with two case studies from Minority Education Project in Oakland, California. 相似文献

Child abuse: adolescent records vs. adult recall 总被引:4,自引:1,他引:4
In a follow-up study of incarcerated Connecticut youth, 69 subjects were interviewed during young adulthood. On follow-up, 26 gave histories of abuse discrepant with histories obtained from records and interviews conducted in adolescence. Eleven subjects agreed to an additional clarification interview, at which time they were apprised of the discrepancies. Of these, eight had adolescent records indicating that abuse had occurred but denied abuse during the adult follow-up interview. The remaining three had adolescent records indicating no abuse had ever occurred, but, on follow-up, reported having been abused. The additional clarification interviews revealed that all 11 subjects with discrepant histories had, in fact, been abused. Reasons for these discrepant data and strategies to enhance the investigator's ability to obtain accurate data regarding abuse are discussed. 相似文献
