ABSTRACT
This chapter seeks to present a challenge to the problem-based learning community about the possibilities for reinventing problem-based learning as both a philosophy and an approach to learning. What I offer is not just a constellation of questions and a number of big ideas, but instead some suggestions and priorities. It will be argued here that the notions of liminality and liquidity in the context of reconceptualization of learning spaces may offer some purchase on the questions and issues we face as a community and increasingly as an online learning community. This chapter will therefore suggest some options and possibilities, but it will begin by arguing that we need to see the shifts required as being located in the realms of ‘new collegiality’ and akin to a Second Life for problem-based learning. This is not only because it is a transformational position but also because we need to engage more deeply with Web 2.0 technologies and learning in liminal spaces such as 3D worlds. However, it will be argued that:
1 We need to reinvent PBLonline as a much more troublesome learning space than it is already.
