Traditional approaches to learning have often focused upon knowledge transfer strategies that have centred on textually-based engagements with learners, and dialogic methods of interaction with tutors. The use of virtual worlds, with text-based, voice-based and a feeling of 'presence' naturally is allowing for more complex social interactions and designed learning experiences and role plays, as well as encouraging learner empowerment through increased interactivity. To unpick these complex social interactions and more interactive designed experiences, this paper considers the use of virtual worlds in relation to structured learning activities for college and lifelong learners. This consideration necessarily has implications upon learning theories adopted and practices taken up, with real implications for tutors and learners alike. Alongside this is the notion of learning as an ongoing set of processes mediated via social interactions and experiential learning circumstances within designed virtual and hybrid spaces. This implies the need for new methodologies for evaluating the efficacy, benefits and challenges of learning in these new ways. Towards this aim, this paper proposes an evaluation methodology for supporting the development of specified learning activities in virtual worlds, based upon inductive methods and augmented by the four-dimensional framework reported in a previous study.The study undertaken aimed to test the efficacy of the proposed evaluation methodology and framework, and to evaluate the broader uses of a virtual world for supporting lifelong learners specifically in their educational choices and career decisions. The paper presents the findings of the study and considers that virtual worlds are reorganising significantly how we relate to the

Abstract. This paper presents the results of a usability evaluation of the NeuroSky's MindBuilder -EM (MB). Until recently most Brain Computer Interfaces (BCI) have been designed for clinical and research purposes partly due to their size and complexity. However, a new generation of consumeroriented BCI has appeared for the video game industry. The MB, a headset with a single electrode, is based on electro-encephalogram readings (EEG) capturing faint electrical signals generated by neural activity. The electrical signals across the electrode are measured to determine levels of attention and then translated into binary data. This paper presents the results of an evaluation to assess the usability of the MB by defining a model of attention to fuse attention signals with user-generated data in a Second Life assessment exercise. The results of this evaluation suggest that the MB provides accurate readings regarding attention, since there is a positive correlation between measured and selfreported attention levels. The results also suggest there are some usability and technical problems with its operation. Future research is presented consisting of the definition of a standardized reading methodology and an algorithm to level out the natural fluctuation of users' attention levels when used as inputs.

As virtual worlds come of age, their potential for applications supporting teaching and learning is becoming increasingly recognised. This chapter outlines a transition of learning, centring on the uptake of new tools for supporting Technology Enhanced Learning (TEL) in universities and colleges. In particular, the use of technologies such as virtual worlds is increasing the pedagogic toolkit of teachers and tutors, providing unique opportunities to support and enhance teaching and learning. In particular, the use of virtual worlds to reach remote, distance, and online learners is creating new opportunities for face-to-face engagement and motivation with difficult-to-reach groups. To evidence and explore this potential, this chapter documents the main findings from several studies which focus upon defining and examining the key components which contribute towards the efficacy of an ‘immersive learning experience’. This includes the main findings of the UK JISC-funded MyPlan project, wherein Second Life, a desktop virtual world, was used to support career decisions and educational choices among two groups of learners, the first from a college and the second from a university. These findings are compared to those arising from the UK Technology Strategy Board-funded Serious Games: Engaging Training Solutions (SG-ETS) project, which sought to develop and assess three high-fidelity serious games. The chapter focuses upon four specific components of virtual worlds and immersive learning techniques: personalisation through learner modelling, integrative feedback, intrinsic motivational quality, and what the authors term ‘social interactive learning’. These four criteria are discussed with respect to the study, providing a basis for future ongoing studies that explore the efficacy of immersive virtual worlds as an alternative for, and supplement to, traditional learning environments.

This paper presents an evaluation of the societal impact of a simulation-based Serious Game. FloodSim was developed with the aim of raising awareness of issues surrounding flooding policy and citizen engagement in the UK. The game was played by a large number of users (N=25,701) in a period of 4 weeks. Quantitative and qualitative analyses (on a reduced data set) were carried out in order to explore the impact of FloodSim play in raising the general public awareness around flooding in the UK. The results suggest FloodSim was hugely successful in generating general public interest and there was evidence that (a) FloodSim increased awareness at a basic level and (b) that despite the simplicity of the simulation, players perceived FloodSim to be an accurate source of information about flood risk and prevention. This suggests that serious games such as FloodSim have potential to engage the public and raise awareness of societal issues. However, FloodSim only raised awareness at a basic level. It is suggested that more needs to be done to endow serious games with pedagogical principles and more care should be given to the accuracy of the information they convey. The appropriateness of games as an educational medium for raising awareness of complex, real-life issues should also be carefully considered. This study throws some light on the potential of simulation-based Serious Games to offer experiential learning, engage users with serious topics while raising public awareness and understanding of social issues such as flooding and related policymaking. Future research is outlined consisting of identifying the problems and challenges in designing and developing serious games while considering pedagogical principles.
