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

From a number of ML estimators (typically unbiased) of practical interest which include the variance for a Gaussian distribution, the standard deviation for a Laplace distribution, the variance for a Rayleigh distribution and a “spread parameter” for a Cauchy distribution, we design robust estimators according to an emphasis balance between normalized performance and normalized robustness. We measure performance with inverted MSE and robustness with a differential geometric approach. 相似文献

This paper explores the management and outcomes of a specific model of intergenerational learning, concerned with student digital leader support in a number of secondary schools in England. A local educational partnership set up a student digital leader project late in 2011, which aimed to develop a range of skills and outcomes for both the digital leaders themselves and for a potentially wider variety of personnel within the schools. Five schools were involved in the project. The student digital leaders shared their digital technology expertise with others with less developed skills, including teachers and managers in these schools. The study reported in this paper explored ways that the digital leader initiative was implemented, identifying and analysing outcomes and issues arising. Evidence from informants and from the analysis of benefits arising indicates that the student digital leader initiative led to a variety of positive outcomes. A key finding and conclusion is that this form of initiative has involved some students who tend not to be involved in other leadership or school-wide activities. The initiative enables these students to contribute to the community, rather than just receiving from it; students become active contributors to, as well as receivers from, the educational system. 相似文献

Intergenerational learning (IGL) has been identified as a viable way to help organizations deal with the problems an ageing worker population brings with it. Information and communications technology (ICT) in its many forms can be utilized to support IGL. This paper investigates the requirements for a game that would help raise stakeholder awareness for IGL, and allow individuals to practice skills related to it. By interviewing members of the European Union (EU)-funded SILVER-project we aim to find out suitable contexts, interventions and mechanisms that allow us to design such a game. Based on the interviews we found out that the game should be easily contextualized so that it works in—or is easily adapted to—different countries and cultures. For example sports or nature could be such contexts. As for mechanisms and interventions we found out that there are many possibilities. We conclude that such a logical combination of mechanisms and interventions that support the selected context must be chosen. 相似文献
