Identifying innovation in higher education elearning strategies

There are many case studies of individual Higher Education Institutions (HEIs) devising distinctive eLearning strategies, reported by the HEI itself, journalists, or research observatories. An extraordinarily wide range of university-level eLearning programmes are rapidly becoming available from large numbers of HEIs across Europe, and there are strong attempts being made to identify and disseminate case studies of innovative eLearning practices (e.g. MENON, 2006). However, the vital research goal of obtaining more systematic evidence across countries in relation to HEIs' innovations in eLearning strategies represents a particular challenge for collectors of case studies, especially given the diverse processes in different countries for measuring pedagogical value and cost-effectiveness. By contrast, there are typically several reports a year of large-scale attempts to survey HEIs in relation to eLearning, sponsored, for example, by EU programmes or industry groups. Yet the factors that determine educational effectiveness are not, so far, well understood; and consequently it can be difficult to develop reliable quantitative survey items that simultaneously enable valid and insightful comparisons between essentially qualitative eLearning strategies. Moreover, such quantitative evidence is not collected systematically by the typical HEI; when collected, such evidence is commercially sensitive; and it is not easy for researchers to obtain independently of the HEI. So, claims are made, for example, that European universities plan to 'expand their use of eLearning' (BBC News, 2005), but it is not at all clear what measures of expansion are appropriate, and what kinds of strategies are associated with such expansion. The two-year research study described here attempted a mixed-method approach to the problem of identifying examples of innovation in relation to the eLearning strategies developed by HEIs. Where possible the study estimated the impact of the implemented eLearning programmes, but the emphasis was on illuminating a range of innovative eLearning strategy cases, rather than necessarily determining best practice. Two key research questions asked by the study are: 1. How can innovation in Higher Education eLearning strategies be identified? 2. What factors are critical to the success of these strategies? This research did not set out to obtain, directly, insight into why eLearning has not been more widely adopted by HEIs, why various eLearning projects have failed, why some eLearning projects have achieved less success than anticipated, or why some eLearning projects have achieved success more slowly than anticipated. However, by researching innovation, the challenges faced by the innovators, and how strategies needed to change over time, it is anticipated that the findings from this study might indirectly illuminate these crucial questions. It is not possible within the space available here to do more than outline the methodology and highlight a few key findings: fuller reports are available on the project website www.spi.pt/innounilearning

The fostering of innovative eLearning strategies in European higher education

Although there are strong attempts being made by various European observatories and European Commission programmes to identify and disseminate innovative eLearning practices (MENON, 2006), the factors that determine educational effectiveness are, as yet, not well understood. In particular, while an extraordinarily wide range of university-level eLearning programmes are rapidly becoming available from large numbers of Higher Education Institutions (HEIs) across Europe, the sharing of good practice requires detailed accounts of successful innovative eLearning strategies. There are many relevant checklists and sets of principles described in EU websites (e.g. elearningeurope.info, 2006) and in the academic literature (e.g. Conole et al, 2004), but it is often only through thoroughly appreciating what others have done that such abstract guidance come alive. However, it can still be difficult for HEIs to learn from others. While there are many media reports of innovation, these typically have to omit the level of detail that would enable optimal understanding by those HEIs wishing to apply such innovations in their own contexts. Meanwhile, case studies presented at conferences and in the academic literature can provide the necessary level of detail, but it can be difficult to collate such case studies into a form that facilitates consistent descriptions across the diversity of European HEIs. By identifying the various eLearning programmes applied by HEIs in a number of EU member states and conducting a detailed assessment of a sample of eLearning strategies found to be effective supporters of higher education requirements, the EC-funded InnoUniLearning project is disseminating a range of eLearning strategy case studies. Where possible this project is estimating the potential impact of the implemented eLearning programmes, but more importantly it will identify and detail the strategies applied by leading institutions and well-known success stories, as well as those institutions that have applied new and innovative eLearning programmes. It is hoped that the dissemination of these case studies will be of assistance to HEIs across Europe in implementing eLearning strategies that meet their own particular curricular and cohort requirements. The study is concentrating on illuminating a range of successful eLearning strategy cases, rather than necessarily determining best practice, which could be argued an impossible task at the moment because of a lack of learner feedback. Nevertheless, most, if not all, organisations that have implemented eLearning have gone through a period of adjustment in order to obtain an eLearning programme that is cost-efficient and effective; so capturing something of the challenges overcome by the HEIs leading this field should assist the wider EU higher education community. This paper describes background and the methodological approach of the two-year study and some preliminary results, which will be elaborated in the conference presentation
