In order to improve user experience and to foster novel ideas, some voices in the HCI community have argued to break fundamental design rules, an approach well known in the art community. In this paper, we use this radical approach to design a playful mobi ...

Nowadays, the knowledge economy is growing rapidly. To sustain future growth, more well educated people in STEM (science, technology, engineering and mathematics) are needed. In the Go-Lab project we aim to motivate and orient students from an early age on ...

Peer assessment is seen as a powerful supporting tool to achieve scalability in the evaluation of complex assignments in large courses, possibly virtual ones, as in the context of massive open online courses (MOOCs). However, the adoption of peer assessmen ...

Open Educational Resources (OERs) are freely accessible, openly licensed multimedia documents or interactive tools that can be typically integrated in Learning Management Systems to support courses. With social media platforms becoming the central piece of ...
