Context: Exploring the design space is an important process in a design task. In this study, we considered design space exploration for the learners in vocational education and training (VET). The goal of the study was to investigate how they explore the design space while focusing on the effect of a graph-like interface on the learner's…

We investigated the role that tangibility plays in a problem-solving task by observing logistic apprentices using either a multitouch or a tangible interface. Results showed that tangibility helped them perform the task better and achieve a higher learning gain. In addition, groups using the tangible interface collaborated better, explored more…

No systematic empirical study on investigating the effects of performing task variants on user cognitive strategy and behaviour in usability tests and on learnability of the system being tested has been documented in the literature. The current use-inspired basic research work aims to identify the underlying cognitive mechanisms and the practical…

Online education encompasses a variety of technologies, one of which is lecture capture--a long-standing practice at the University of Geneva. The faculty of arts has recorded most of its lectures on audiotapes since the 1970s, well before the World Wide Web existed. Modernization of the recording technologies, however, which until recently…

This paper describes an ongoing experiment at the Swiss Federal Institute of Technology in Lausanne regarding the use of World Wide Web-based document annotations for educational purposes. An annotation tool called Medium was built, merging database and Web technologies, to be used as a companion for classical university courses and collaborative…
