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)
If multi-tabletop classrooms were available in each school, how would teachers plan and enact their activities to enhance learning and collaboration? How can they evaluate how the activities actually went compared with the plan? Teachers' effectiveness in orchestrating the classroom has a direct impact on students learning. Interactive tabletops offer the(More)
Touch-based tabletops are a form of embedded device for group collaboration. This work tackles two key problems for effective use of such tabletops: there is currently no easy way for people to identify themselves to the table; and most current hardware does not link a person's touches to their identity. This paper presents a system which tackles these(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)
Electronic traces of activity have the potential to be an invaluable source to understand the strategies followed by groups of learners working collaboratively around a tabletop. However, in tabletop and other co-located learning settings, high amounts of unconstrained actions can be performed by different students simultaneously. This paper introduces a(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)
It is of high relevance to the LAK community to explore blended learning scenarios where students can interact at diverse digital and physical learning spaces. This workshop aims to gather the sub-community of LAK researchers, learning scientists and researchers from other communities, interested in ubiquitous, mobile and/or face-to-face learning analytics.(More)
There is a fast growing interest in the use of interactive surfaces in collaborative learning contexts. These devices hold the promise to enrich a typical collocated class by enabling learners to interact with digital content while maintaining face-to-face mutual awareness. However, little has been done to help teachers deploy and monitor the learning(More)
