- We report on an exploratory study where the first 60 seconds of the video recording of a user interaction are used to predict the user’s experienced task difficulty. This approach builds on previous work on “thin slices” of human-human behavior, and applies it to human- computer interaction. In the scenario of interacting with a photocopy machine, automated video coding showed that the Activity and Emphasis predicted 46.6% of the variance of task difficulty. This result closely follows reported results on predicting negotiation outcomes from conversational dynamics using similar variables on the speech signal.

Konferensbidrag (refereegranskat)abstract
- This paper shares the experiences of 5 universities involved in a benchmarking exercise on e-learning in 2009 through ESMU. A total of 9 European universities participated in the exercise with the purpose of evaluating their existing e-learning practices and policies and getting advice on which areas to improve and how. Initially, the paper discusses the benchmarking concept and reasons why institutions should engage in benchmarking exercises. Benchmarking is viewed as a method for quality assurance and enhancement in higher education. Self-assessment is involved at the participating institutions, which leads to a high level of awareness and understanding of existing practices and policies at different levels of the organisation. Benchmarking is thus an efficient self-improvement tool. In chapter two, the planning of the benchmarking exercise is outlined. A combination of an individual, collaborative and expert approach to benchmarking was chosen. Chapter three deals with the creation of the benchmarking questionnaire which was a collaborative effort between all nine participating universities, ESMU and EADTU. Taking their starting point in the online E-xellence benchmarking tool developed by EADTU, participants reformulated, deleted and added benchmarks within the following six categories: Strategic management, curriculum design, course design, course delivery, staff support and student support. An effort was made to translate the E-xellence questions to the blended learning context of the participating universities. The internal data collection and formulation of responses are accounted for in chapter 4 which also contains reflections on the challenges and benefits of the selected approaches. Chapter five presents the overall conclusions of the benchmarking exercise within each of the six benchmark categories. The final chapter discusses and provides examples of how participants can use the benchmarking results to improve existing practices and policies and outlines potential external collaboration opportunities between participants.
