There are many influences on how assessors grade themselves and others. Oral presentations are useful for exploring such factors in peer, self‐ and tutor marked assessments, being rapidly completed and assessed, commonly used in HE and very difficult to anonymize. This opportunistic study examined the effects of gender and level of attainment on the triangulation of marks awarded to student presenters. Grades generated by peer assessment were associated more strongly with tutor‐awarded marks than those from self‐assessment. For self‐assessment there was a strong effect of gender (female students undervalued their performance compared with tutor grades). Peer assessment produced higher marks than from tutors, perhaps because of the close‐knit community developed during residential courses. For tutor marks, the greatest variability was at the lower end of the scale, whereas peer assessors were most variable when marking students who self‐evaluated or peer assessed highly. Students awarded a narrower range of marks to peers compared with tutors, but when self‐assessing used a larger range. Presentations by students who admitted to little sleep the night before received lower grades from both peers and tutors, but this was not reflected by self‐assessments, suggesting they were unaware of their poorer performances. Sessions with fewer talks (four rather than seven) reduced the ‘dip’ in marks previously observed in the middle of sessions. Findings are discussed in the context of bias in this mode of assessment. 相似文献

We use the 2003 National Survey of College Graduates to provide the first estimates of the effect on earnings of having a double major. Overall, double majoring increases earnings by 2.3% relative to having a single major among college graduates without graduate degrees. Most of the gains from having a double major come from choosing fields across two different major categories. Graduates who combine an arts, humanities or social science major with a major in business, engineering, science or math have returns 7–50% higher than graduates with a single major in arts, humanities or social science. But such double major combinations have returns no higher than single majors in business, engineering, science or math. Majors combining business and science or math have returns more than 50% greater than the returns to having a single major in these fields. 相似文献

The internationalisation of higher education aims to produce ‘citizens that feel at home in the world’ but the process is driven by both economic and educational motivations. Today, the international community aspires to promote Education for Sustainable Development (ESD) and Education for Democratic Citizenship (EDC), together planetary citizenship, and with them emphases on personal and ethical responsibilities to the environment and future that contrast with current competitive individualism. Driven by rising numbers of international students, curricula are already shifting toward more global assessments of society and environment. However, progress is being impeded by management systems that take commerce as their model. While instructors strive to ensure that learners consider their responsibilities through ESD and EDC, their message is being contradicted by their context. Since learners learn from their total environment, not just in classrooms, changes are required. Granting greater attention to sustainability issues and the empowerment of learners and teachers would allow a better constructive alignment between educational and economic imperatives. 相似文献

“Deep learning” represents student engagement in approaches to learning that emphasize integration, synthesis, and reflection.
Because learning is a shared responsibility between students and faculty, it is important to determine whether faculty members
emphasize deep approaches to learning and to assess how much students employ these approaches. This study examines the effect
of discipline on student use of and faculty members’ emphasis on deep approaches to learning as well as on the relationships
between deep approaches to learning and selected educational outcomes. Using data from over 80,000 seniors and 10,000 faculty
members we found that deep approaches to learning were more prevalent in Biglan’s soft, pure, and life fields compared to
their counterparts. The differences were largest between soft and hard fields. We also found that seniors who engage more
frequently in deep learning behaviors report greater educational gains, higher grades, and greater satisfaction with college,
and that the strength of these relationships is relatively consistent across disciplinary categories. 相似文献

Enhancing student motivation and engagement: The effects of a multidimensional intervention 总被引:2,自引:1,他引:1
The present study sought to investigate the effects of a multidimensional educational intervention on high school students’ motivation and engagement. The intervention incorporated: (a) multidimensional targets of motivation and engagement, (b) empirically derived intervention methodology, (c) research-based risk and protective factors, (d) established practices that nurture optimal youth development, (e) use of interpersonally skilled staff, and (f) evidence-based programming. Using a pre-/post-treatment/control group design, it was found that the self-complete intervention brought about significant shifts in motivation and engagement. Specifically, findings showed that the treatment group made positive motivation shifts on key dimensions including task management, persistence, anxiety, failure avoidance, and uncertain control. Moreover, against a large weighted external comparison group, the treatment group made positive shifts on valuing, mastery orientation, planning, task management, persistence, failure avoidance, uncertain control, and self-handicapping. Taken together, these findings attest to the potential for multidimensional educational interventions for enhancing students’ motivation and engagement. 相似文献

In recent years, there has been a feeling that effective teachers can be fostered by grounding professional development in actual classroom practice. This paper reports how a group of teachers adopted a lesson study approach and worked collaboratively so as to improve their class instruction on wh-question formation. Teachers’ reflections indicate that the collaborative environment throughout the study enabled them to gain insights into how to improve their teaching strategies. Also identified are some of the problems faced by teachers, which may undermine the gains of lesson study. 相似文献

The relationship among achievement goals,standardized test scores,and elementary students’ focus in school 下载免费PDF全文
The study examined whether an academic, social, or both an academic and social focus might relate with achievement goals and academic achievement. Participants were 412 urban elementary school students. Results suggest that students with an academic focus toward school have more mastery‐approach and less mastery‐avoid achievement goals. Academic achievement (standardized test scores) did not relate with boys’ or girls’ focus toward school. These findings suggest that academic motivation, but not achievement, correspond with self‐perceptions of school as being a place to learn or school as a place for social interactions. 相似文献

ABSTRACTIn this paper, we investigate how a Benchlearning program for principals in Norway and Sweden supports changes in Norwegian principals’ leadership practices. The program design builds on principles for practical action research. The aim of the program was to inspire changes in the principals’ leadership practices that encourage innovative school practices. The program includes learning modes such as theoretical inputs, sharing experiences, school visits, training, and trialling of new leadership practices. Drawing on data from participants’ reflections on their learning and changes in their leadership practices, we identify transformations that have been realized and the ways in which the Benchlearning program has supported the transformations. The findings indicate that the program can be seen as a systematic and disciplined process, a ‘meta-practice’, that supports changes in the principals’ leadership practices, their understandings, and the conditions of their practice. More specifically, the findings show that the theoretical inputs and practical learning modes stimulated transformations of the principals’ thinking about leadership practices, what they do in practice and how they relate to others. In particular, the study suggests that the principals’ active participation in trialling new leadership practices in their own schools stimulated transformations. 相似文献

For a channel-shoal system in a funnel-shaped basin the impact of dredging and dumping is investigated using a complex process-based
model. First, the residual flow and sediment transport circulations are analysed for the channel-shoal pattern, which has
emerged after a long-term model simulation. Results are compared to the Western Scheldt estuary, which forms the inspiration
for this study. Subsequently, different dredge and dump scenarios are modelled, according to a conceptual model, in which
ebb-and flood-channels and enclosed shoals form morphodynamic units (cells) with their own sediment circulation. Model results
show that dumping sediment in a channel further reduces the channel depth and induces erosion in the opposite channel, which
enhances tilting of the cross-section of the cell and eventually can lead to the degeneration of a multiple channel system
into a single channel. The impact of different dredging and dumping cases agrees with results from a stability analysis. This
means that this type of model applied to a realistic geometry can potentially be used for better prediction of the impact
of human interventions. 相似文献
