Student & tutor consensus: a partnership in assessment for learning     

James Thompson  Don Houston  Kathryn Dansie  Timothy Rayner  Timothy Pointon  Simon Pope 《Assessment & Evaluation in Higher Education》2017,42(6):942-952

The mistakes made when attempting tasks often prove to be some of the most invaluable learning experiences. Despite this, outcome and results driven assessment formats largely penalise student performance errors or reward students who succeed by chance. The consequences of this paradigm are visible effects on student relationships with assessment. The student–tutor consensus approach to assessment was introduced to capture student learning achieved ‘from’ assessment to complement the measurement of performance outcomes. This approach parallels student and tutor judgement in a grade negotiation, affording the student an opportunity to share with their assessor what they have learned from the assessment activity. This student self-awareness was then considered alongside the conventional outcome-based score awarded by the tutor to generate a final grade for the assessed activity. Our study evaluated the perceptions of 90 undergraduate students enrolled in the bachelor of paramedic studies, who participated in this novel assessment approach as part of a final-year capstone topic. The results comprehensively indicated value for all aspects of the assessment approach, as well as a recognition that the skills will be useful in their future professional roles.  相似文献   

一些足以破解疑古思想的论述——现代学者关于古代书体书例的总结     

张京华 《湘南学院学报》2006,27(6):31-34

自从20世纪初顾颉刚等首倡“疑古辨伪”以来,学者多方寻求“重建古史”的途径。在重申“史官史职”与注重考古发掘的同时,对于古代“书体书例”的归纳总结亦不失为一条有效的重建之路。  相似文献

异构数据库更新同步研究与实现     

肖刚 《教育技术导刊》2019,18(10):182-185

数据库同步是实现不同系统之间数据共享的有效方法。现有异构数据库同步模型能有效解决记录的同步新增,但由于同步记录查询基于数据表名和关键字值,若不考虑同步数据库节点变化,将导致数据库不适用于某些遗留系统。针对该问题,提出同步控制和主从记录映射方法,在同步控制层记录主从记录映射关系。在采用双向中间件方法的同步技术基础上,设计基于标准数据格式的数据转换,降低数据转换模块开发维护成本,并根据模型应用WCF框架实现系统。实践应用表明,该模型可实现异构数库之间同步更新。  相似文献

The effect of adaptivity on the reliability coefficient in adaptive comparative judgement     

Tom Bramley  Sylvia Vitello 《Assessment in Education: Principles, Policy & Practice》2019,26(1):43-58

Comparative Judgement (CJ) is an increasingly widely investigated method in assessment for creating a scale, for example of the quality of essays. One area that has attracted attention in CJ studies is the optimisation of the selection of pairs of objects for judgement. One approach is known as adaptive comparative judgement (ACJ). It has been claimed in the literature that ACJ produces very high reliability, often higher than can be obtained by conventional marking. Bramley showed by simulation that adaptivity can substantially inflate the apparent reliability in ACJ. The empirical study described here compared an adaptive with a non-adaptive CJ study using GCSE English essays. An all-play-all set of comparisons of a subset of the essays allowed the extent of scale inflation to be quantified: the reported adaptive reliability was 0.97 whereas the deflated value was 0.84. The value from the non-adaptive study was 0.72. However, the scale from the non-adaptive study correlated slightly higher with external variables, suggesting the non-adaptive study was no less valid than the adaptive one.  相似文献   

Strategies for using feedback students bring to higher education   总被引：1，自引：1，他引：1  

Deirdre Burke 《Assessment & Evaluation in Higher Education》2009,34(1):41-50

This article explores strategies for acting on feedback that students bring to their higher education, by exploring student perceptions on the guidance they received from their teachers in school or college. Whilst assessment issues have been the subject of a range of research studies, it is the contention of this article that little research has been undertaken to identify the strategies that students possess for ‘using’ feedback. This small‐scale research study was stimulated by M.R. Weaver’s 2006 Weaver, M.R. 2006. Do students value feedback? Student perceptions of tutors’ written response. Assessment and Evaluation in Higher Education, 31(3): 379–394. [Taylor & Francis Online] [Google Scholar] finding that only a quarter of students had received guidance on how to use feedback prior to university. This exploration identifies the guidance for using feedback that 350 students in Humanities brought to their degree course. Analysis of responses revealed the strategies that students had been introduced to, identifying nine indigenous categories. Whilst almost 40% of these students indicated they had received guidance for using feedback, scrutiny of responses showed that many of these students confused ‘actual feedback’ with ‘guidance on how to use’ feedback. The implications of such starting positions for students and staff are considered: questioning the adequacy of such a foundation for students to be able to make effective use of the feedback they will receive in their degree course, and finally suggesting initiatives by which staff could enable students to get more out of feedback.  相似文献   

Rapid visual processing by college students in reading irregular words and phonologically regular pseudowords presented singly and in contiguity     

Au A  Lovegrove W 《Annals of dyslexia》2006,56(2):335-360

Using normal adult readers, this study examined the relative involvement of magnocellular and parvocellular processes in reading English phonologically regular pseudowords and irregular words presented in isolation and in contiguity from left to right. The data showed that a low temporal frequency visual measure that implied more parvocellular involvement was active in processing irregular words presented singly and pseudowords presented in contiguity. However, the results failed to show the involvement of the magnocellular pathway (as implicated by low spatial and/or high temporal frequency visual measures) in reading words presented in contiguity from left to right. The discrepancy was discussed in terms of the sensitivity of the tasks used in testing the two pathways.  相似文献
