ABSTRACT

Educators in higher education commonly use peer and self evaluations to help assess student performance on group projects. Although these evaluations provide multiple benefits, many educators are wary of using them due to concerns about their quality. This study addresses three questions debated in the literature regarding the quality of these assessments. How much do students differentiate among peer contributions through their ratings? How reliable are peer ratings? How much agreement exists between peer and self ratings? Although these questions have been addressed to varying degrees in past work, their answers have been far from settled. While many studies focus on just one of the questions, this study’s data make it possible to address all three questions for the same group of students as well as examine each question by student performance level. The evaluations assessed in this study were completed by a large number of students under conditions associated with obtaining more valid and reliable ratings. Overall, the results provide support for using peer and self evaluations to help assess student contributions to group projects. Peer ratings were largely reliable as group members generally agreed on the scores given to their peers. In addition, most students differentiated among group member contributions through their ratings. Students also tended to rate themselves higher than their peers rated them. This study has implications for how peer and self evaluations can be most effectively used by educators to measure student performance in group work.  相似文献

This article draws on current research investigating the notion of design for an unknown future. It reflects on recent thinking about the role of creativity in design practice and discusses implications for the development and assessment of creativity in the design studio. It begins with a review of literature on the issues and challenges associated with the assessment of creativity in design education. It then discusses and distinguishes three significant assessment models in design and creative arts education and emphasises the importance of opening debate on notions of creativity within the discipline. Following this, the article examines recent developments in the way that creativity is being practised, driven, fostered and implemented in contemporary design practice, and argues that these recent developments must feature in current scholarship about the development and assessment of creativity in design education. The article recommends areas for future research that pay close attention to developments in the rapidly expanding field of design practice.  相似文献

Traditionally, working memory has been divided into two major domains: verbal and visuo-spatial. The verbal domain of working memory can be characterized either by its relationship to language or by its grounding in auditory processing. Because of this ambiguity, languages that are not auditory and vocal (i.e., signed languages) pose a challenge to this conception of working memory. We describe several experiments with deaf users of American Sign Language (ASL) that explore the extent to which the architecture of working memory is determined by the constraints of auditory and visual processing and the extent to which it is determined by the characteristics of language. Various working memory effects were investigated: phonological similarity, word length, and articulatory suppression. The pattern of evidence strongly supports the existence of a sign-based 'rehearsal loop' mechanism parallel to the speech-based rehearsal loop. However, we also discuss evidence pointing to differences between the speech loop and the sign loop from forward and backward digit span tasks with deaf and hearing subjects. Despite their similarities based on linguistic properties, the speech loop and the sign loop appear to diverge due to the differing processing demands of audition and vision. Overall, the results suggest that the architecture of working memory is shaped both by the properties of language structure and by the constraints imposed by sensorimotor modality.  相似文献

This study aimed to identify the manner in which university students construe ‘fair treatment’ and how justice related processes are perceived to influence students’ psychological identification with their academic department. In the first study, 342 undergraduate psychology students completed two questionnaires: one measured various aspects of interpersonal, procedural and outcome fairness in their department, and the other measured their level of psychological identification with the department. Students construed the fairness of their learning environment in terms of two conceptually distinct justice factors: respectful partnership between staff and students reflecting primarily interpersonal justice considerations; and systemic fairness reflecting a concern for accessible information and effective problem‐solving procedures. Hierarchical regression analyses indicated that although both justice factors significantly influenced students’ psychological identification with their department, interactional justice concerns (i.e., respectful staff–student partnership) were most strongly predictive. In the second study (n = 87), students’ perceptions of fairness were found to share substantial variance with their ratings on the good teaching and clear goals scales of the Course Experience Questionnaire.  相似文献

This paper examines a theoretical perspective on the ways in which children progress in learning mathematics. It suggests that there is a difficulty in associating teaching discourses with the mathematics they locate. This can result in an incommensurability between alternative perspectives being offered. The paper resists attempts to privilege any particular account but rather demands an analysis of these discourses and their presuppositions. In developing these themes the paper invokes Ricoeur's analysis of time and narrative as an analytical approach to treating notions such as transition, development and progression in mathematical learning. His notion of semantic innovation is introduced. This embraces both the introduction of a new metaphor into a sentence or the creation of a new narrative which reorganises events into a new plot. The notion is utilised in arguing that the shift in the student's mathematical development from arithmetic to first order linear equations with unknowns reconfigures the contextual parameters governing the understanding of these mathematical forms. It is also utilised in showing how alternative approaches to accounting for such transitions suit different and perhaps conflicting outcomes. For example, demonstrating awareness of generality or performing well in a diagnostic test featuring the solution of linear equations.This revised version was published online in September 2005 with corrections to the Cover Date.  相似文献

Community colleges in Tennessee, either directly or indirectly, experienced unprecedented change as a result of Tennessee Promise. The present study explored how student support service administrators at three community colleges responded to organizational change as a result of the Tennessee Promise legislation. Investigators selected community colleges for the multi-site case study because the legislative impact would be actualized by the preparations made to serve incoming Promise recipients. The delivery of orientation services framed organizational change because the service staff facilitate connections and provide information to incoming students. Challenges like a shifting population, ill-equipped infrastructure, inadequate remediation support, heightened interest for social engagement opportunities, misinformation, and unmet fiscal needs left administrators seeking coherence through the change process. Investigators found community college administrators react to change similarly. Administrators acknowledged change as continuous, created a culture of innovation among stakeholders, and were not afraid to fail as responses to the organizational change phenomenon.  相似文献
