Purpose -The purpose of this paper is to investigate online problem-based learning (PBL) as a route to achieving sustainability education using sponsored projects. Design/methodology/approach -The Royal Academy of Engineering sponsored project at Manchester; to foster education in sustainability through inter-disciplinary problem-based approaches, has since been extended to other groups and to a broader array of issues. One of the limiting factors is the ease with which this approach can be taken in the case of large numbers of students and a commensurate requirement for large numbers of facilitators. The University of Keele, together with partners from the universities of Manchester and Staffordshire, was awarded National Teaching Fellowship Scheme funding to explore further the use of blended or online approaches, in order to overcome these limitations. The pilot unit already has a certain amount of support using the BlackBoard virtual learning environment (VLE) but this scenario is supposed to rely entirely on online working. At the time of writing, the evaluation of the pilot has not been completed but an online questionnaire was devised to monitor students' reactions to the online working and to ascertain whether they did in fact work entirely online or whether they chose to meet informally face-to-face. Difficulties encountered were both organizational (mostly relating to enrolment) and technical (this was a new version of BlackBoard and had a few teething troubles). Findings -This pilot project has demonstrated that a blended approach to PBL is feasible. There are some forms of resistance from students. The assessment was outcomes-driven rather than processdriven. This meant that it was not necessary for the academic staff to have access to all the discussions, thus acting as facilitators. There is a general theme that while learners found it possible to work effectively as a group online, they also found it more difficult. It is possible that the students were having to dedicate more time and effort to the use of the online system, which had an impact on their creativity and productivity. Research limitations/implications -In the case of the University of Manchester, the developments are being applied to a Masters-level course unit in Managing Humanitarian Aid Projects. This unit proceeds on the basis of five scenarios that students try to resolve in small groups and in the first pilot year one of these scenarios is being delivered on-line. Practical implications -The results of this pilot could be fed in to different stages of programme deployment to examine impact and explore possibilities with distance learning modules. Originality/value -This paper has looked at the effectiveness of nationally run, problem-based learning projects that are aimed at improving understanding, engagement and deployment on diverse learning environments to include VLEs.

Problem statement:The nature of sustainable development requires new paradigms for education. Issues of sustainability are 'wicked problems' that do not lend themselves to conventional didactic approaches. The challenge for higher education is to examine interdisciplinary approaches to global societal responsibility and, within this, issues of education for sustainable development. Approach: A project, sponsored by the Royal Academy of Engineering, developed a course unit in sustainable development across several disciplines. The approach was initially pedagogic in nature, with a strong evaluative theme. At the same time, a Delphi study was undertaken by the same team and this inter-relates with the main project. The focus of the action research was a series of 'wicked' problems that would provide real-world challenges with no simple answers. Results: The project was evaluated in a number of ways, not least the pre-and post-testing of students' attitudes and approaches, but also using nominal group techniques. The project demonstrated that an interdisciplinary PBL approach succeeded in deepening the learning of the students as well as developing key skills. Conclusion: The use of collaborative, group-based approaches, notably PBL, offers a key way of approaching the design of curricula for sustainable development and other areas of global societal responsibility that hinge on 'wicked problems'.
