<i>Concept mapping</i> is a technique where users externalise their conceptual and propositional knowledge of a domain in a way that can be readily understood by others. It is widely used in education, so that a learner's understanding is made available to their peers and to teachers. There is considerable potential educational benefit in collaborative(More)
Tabletops have the potential to provide new ways to support collaborative learning generally and, more specifically, to aid people in learning to collaborate more effectively. To achieve this potential, we need to gain understanding of how to design tabletop environments so that they capture relevant information about collaboration processes so that we can(More)
While a number of guidelines exist for the design of learning applications that target a single group working around an interactive tabletop, the same cannot be said for the design of applications intended for use in multi-tabletops deployments in the classroom. Accordingly, a number of these guidelines for single-tabletop settings need to be extended to(More)
Large amounts of data are generated while students interact with computer based learning systems. These data can be analysed through data mining techniques to find patterns or train models that can help tutoring systems or teachers to provide better support. Yet, how can we exploit students' data when they perform small-group face-to-face activities in the(More)
Designing, deploying and validating learning analytics tools for instructors or students is a challenge requiring techniques and methods from different disciplines, such as software engineering, human-computer interaction, educational design and psychology. Whilst each of these disciplines has consolidated design methodologies, there is a need for more(More)
Inspired by the promise of tabletops for collaborative learning, and building on the many tabletop lab studies, and a few in-the-wild tabletop classrooms, we designed the first semester-long use of a multi-tabletop classroom for two university subjects, with 105 and 40 students respectively. Surprisingly, we found that with just three applications, designed(More)
There are many contexts where it would be helpful to model the collaboration of a group. In learning settings, this is important for classroom teachers and for students learning collaboration skills. Our approach exploits the digital and audio footprints of the users' actions at collocated settings to automatically build a model of symmetry of activity.(More)
