Rethinking feedback practices in higher education: a peer review perspective

Peer review is a reciprocal process whereby students produce feedback reviews on the work of peers and receive feedback reviews from peers on their own work. Prior research has primarily examined the learning benefits that result from the receipt of feedback reviews, with few studies specifically exploring the merits of producing feedback reviews or the learning mechanisms that this activates. Using accounts of their experiences of peer review, this study illuminates students’ perceptions of the different learning benefits resulting from feedback receipt and feedback production, and, importantly, it provides insight into the cognitive processes that are activated when students construct feedback reviews. The findings show that producing feedback reviews engages students in multiple acts of evaluative judgement, both about the work of peers, and, through a reflective process, about their own work; that it involves them in both invoking and applying criteria to explain those judgements; and that it shifts control of feedback processes into students’ hands, a shift that can reduce their need for external feedback. The theoretical and practical implications of these findings are discussed. It is argued that the capacity to produce quality feedback is a fundamental graduate skill, and, as such, it should receive much greater attention in higher education curricula.

Embedding an integrated learning environment and digital repository in design engineering education: lessons learned for sustainability

This paper describes how a system comprising a learning environment and digital repository is being embedded into the teaching and learning of Design Engineering at the University of Strathclyde. It then maps out the issues that have been encountered, how these have been overcome and how other departments or institutions would be affected if they were to roll out and scale up the use of such tools. These issues are categorised as technological, pedagogical and cultural, and include the adequate provision of support, creating a critical mass of resources, ensuring quality and integration with other technologies. Successful embedding and sustainability requires that senior managers reflect on these key issues at a departmental and/or institutional level before implementation.

Comparing diagnoses from expert systems and human experts

This paper discusses a comparison of one heuristic and two Bayesian belief network based expert systems used to aid veterinarians in the process of differential diagnoses of equine diseases where coughing is the presenting clinical sign. Each implementation infers the likelihood of the presence of a number of diseases based on information on the presence or absence of certain clinical signs. The Bayesian belief network approaches are similar except that one includes the use of prior information in the form of disease prevalence estimates. Both are implemented using the Hugin software package. The three approaches were compared using test cases and the lists of resulting diagnoses were examined for agreement using a measure of concordance. The results indicated a difference between the heuristic approach which used the rule-based scoring mechanism and the Bayesian systems. There was, however, little difference between the diagnoses produced by the two Bayesian implementations, indicating that the incorporation of prevalence data makes little difference in diagnostic systems of this type. The findings were also compared with those of clinical experts. The analysis indicated that clinicians were not always in agreement. Moreover, using the same set of test cases the experts were more in agreement with the Bayesian approaches than with the heuristic approach.

An evaluation study of a digital library of ideas: Workflow Model and classroom use

The Department of Design Manufacturing and Engineering Management at the University of Strathclyde, Glasgow, UK, has been developing a digital library to support design engineering student learning through the Digital Libraries for Global Distributed Innovative Design Education and Teamwork project (http://www.didet.ac.uk, December, 2007). Previous related studies have observed and analysed how students search for, store, structure and share design engineering information (Grierson et al. in paper presented at the Network Learning Conference, pp. 572–579, 2004; Nicol et al. in Open Learning 20(1):31–49, 2005) and these studies have identified the need for the design and development of a digital library with two system components, which best suit the design process: (i) an informal shared workspace; the ‘LauLima’ Learning Environment and (ii) a repository of more formal searchable and browsable design information; the ‘LauLima’ Digital Library (McGill et al. in Br. J. Educ. Technol. 36(4):629–642, 2005). This paper focuses on the Workflow Model developed to populate the digital library and presents findings from early use of the digital library by students and staff.

A framework for design engineering education in a global context

Abstract This paper presents a framework for teaching design engineering in a global context using innovative technologies to enable distributed teams to work together effectively across international and cultural boundaries. The Digital Libraries for Global Distributed Innovative Design, Education, and Teamwork (DIDET) Framework represents the findings of a 5-year project conducted by the University of Strathclyde, Stanford University, and Olin College that enhanced student learning opportunities by enabling them to partake in global, team-based design engineering projects, directly experiencing different cultural contexts and accessing a variety of digital information sources via a range of innovative technology. The use of innovative technology enabled the formalization of design knowledge within international student teams as did the methods that were developed for students to store, share, and reuse information. Coaching methods were used by teaching staff to support distributed teams and evaluation work on relevant classes was carried out regularly to allow ongoing improvement of learning and teaching and show improvements in student learning. Major findings of the 5-year project include the requirement to overcome technological, pedagogical, and cultural issues for successful eLearning implementations. The DIDET Framework encapsulates all the conclusions relating to design engineering in a global context. Each of the principles for effective distributed design learning is shown along with relevant findings and suggested metrics. The findings detailed in the paper were reached through a series of interventions in design engineering education at the collaborating institutions. Evaluation was carried out on an ongoing basis and fed back into project development, both on the pedagogical and the technological approaches.
