Portfolio assessment, that is, the evaluation of performance by means of a cumulative collection of student work, has figured prominently in recent US debate about education reform. Proponents hope not only to broaden measurement of performance, but also to use portfolio assessment to encourage improved instruction. Although portfolio assessment has sparked considerable attention and enthusiasm, it has been incorporated into only a few of the nearly ubiquitous large‐scale external assessment programmes in the US. This paper evaluates the quality of the performance data produced by several large‐scale portfolio efforts. Evaluations of reliability, which have focused primarily on the consistency of scoring, have yielded highly variable results. While high levels of consistency have been reached in some cases, scoring has been quite inconsistent in others, to the point of severely limiting the utility of scores.

Information about other aspects of validity is more limited and generally discouraging. For example, scores from portfolio assessments often do not show anticipated relationships with other achievement data, and teachers report practices in the implementation of portfolio assessment that are appropriate for instructional purposes but threaten the validity of inferences from portfolio scores. While other studies show positive effects of portfolio programmes (see Stecher, this issue), these findings suggest that portfolio assessment at its current state of development is problematic for many of the uses to which large‐scale external assessments are now put in the US.  相似文献

This article examines top-producing female authors, editors, and editorial board members in five educational psychology journals (i.e., Cognition and Instruction, Contemporary Educational Psychology, Educational Psychologist, Educational Psychology Review, and Journal of Educational Psychology) from 2009 to 2016. Results extend data from four previous studies (Evans et al. Educational Psychology Review, 17(3), 263–271, 2005; Fong et al. Educational Psychology Review, 21(3), 267–277, 2009; Greenbaum et al. Educational Psychology Review, 28, 215–223, 2016; Robinson et al. Contemporary Educational Psychology, 23, 331–343, 1998) and also compare top female authors to the top male authors. The top-producing women in the field have, on average, less seniority in the field than do top male authors. Male authors have more publications, on average, and more sole authorships and first authorships, as compared to female authors. No discernible progress has been made by women in terms of editorial board memberships or editorships since 2004.  相似文献

This article makes the argument that the present discourse on developmental appropriateness needs to be expanded. Four points are made: First, the present discourse assumes a consensus about child development that is more apparent than real; second, it is premised on a suspect notion of broad, universal stages; third, it ignores an important alternative perspective to the dominant individualist perspective on learning and development; and fourth, it ignores an important alternative perspective to the dominant view of the relationship between learning and development. Critiques are made and alternative perspectives presented.  相似文献

This co-authored article outlines the research process and key findings from the Stratus Writers Project, a participatory action research project with a group of seven students on the autistic spectrum at a university in the North of England. The project explores their experiences of university through critical autobiographies and offers unique insider perspectives into some of the key issues, challenges and successes. Building on a participatory action research approach, the data were collected by the participants themselves; however, this study departs from traditional research in that the participants also analysed the data, thus offering rich and potentially overlooked theoretical knowledge. The article concludes by demonstrating the strength of participatory action research approaches by identifying the impact that our project and its findings have had so far.  相似文献

After receiving events in a fixed order, A-B-C…, rats, like people, on being provided with A, may anticipate not only B, a current anticipation, but also C, a remote anticipation. In two experiments, we attempted to determine whether rats’ remote anticipations are mediated by item cues (C elicited by A) or by position cues (C directly elicited by Position 3 cues, which generalize to Position 2). In Experiment 1, rats in a runway received two series of three trials, XNY and ZNN, each in irregular order each day. N signified nonreinforcement; X, Y, and Z signified three qualitatively different food reinforcements. The rats manifested a remote anticipation by running faster on Trial 2 in the XNY series than in the ZNN series. Since the series were presented irregularly, Trial 2 performance cannot be explained on a positional basis alone. It can be explained on an item basis, by assuming that the memory of the Trial 1 reinforcer became associated not only with the Trial 2 event, but with the Trial 3 event as well. Thus on Trial 2 the memory of X signaled N and Y, whereas the memory of Z signaled N and N. Experiment 2 produced the same results, regardless of whether the XNY and ZNN series were presented in regular or irregular order. These results indicate that remote anticipations can be mediated by item associations. They offer no evidence that position associations can do the same, but they do not rule out that possibility.  相似文献

Summer undergraduate research programs in science and engineering facilitate research progress for faculty and provide a close-ended research experience for students, which can prepare them for careers in industry, medicine, and academia. However, ensuring these outcomes is a challenge when the students arrive ill-prepared for substantive research or if projects are ill-defined or impractical for a typical 10-wk summer. We describe how the new Bioengineering and Bioinformatics Summer Institutes (BBSI), developed in response to a call for proposals by the National Institutes of Health (NIH) and the National Science Foundation (NSF), provide an impetus for the enhancement of traditional undergraduate research experiences with intense didactic training in particular skills and technologies. Such didactic components provide highly focused and qualified students for summer research with the goal of ensuring increased student satisfaction with research and mentor satisfaction with student productivity. As an example, we focus on our experiences with the Penn State Biomaterials and Bionanotechnology Summer Institute (PSU-BBSI), which trains undergraduates in core technologies in surface characterization, computational modeling, cell biology, and fabrication to prepare them for student-centered research projects in the role of materials in guiding cell biology.  相似文献

该文考查了远程教育的基础,它的发展历史和它赖以发展进化的技术。历史上有两种传统的远程教育:远程课堂教学和函授教学。它们具有不同的教育学特征和成本结构。然而,新一代技术即知识媒体,作为计算机技术、电子通信技术和认知科学汇同结合的产物,正在将远程教育的两大传统结合在一起。知识媒体将通过进一步发展远程教育对大学的革新作出重大贡献。  相似文献

This study tested the hypothesis that values, abstract goals serving as guiding life principles, become relatively important predictors of adolescents' self-reported violent behavior in school environments in which violence is relatively common. The study employed a students-nested-in-schools design. Arab and Jewish adolescents ( N = 907, M age = 16.8), attending 33 Israeli schools, reported their values and their own violent behavior. Power values correlated positively, and universalism and conformity correlated negatively with self-reported violent behavior, accounting for 12% of the variance in violent behavior, whereas school membership accounted for 6% of the variance. In schools in which violence was more common, power values' relationship with adolescents' self-reported violence was especially positive, and the relationship of universalism with self-reported violence was especially negative.  相似文献
