Identifying Areas of Tension in the field of technology-enhanced learning: Results of an international Delphi study
Computers & Education Vol. 65, No. 1 (July 2013) pp. 92–105
Despite steady progress in research in technology-enhanced learning (TEL), the translation of research findings and technology into educational practices falls short of expectations. We present five Areas of Tension which were identified and...

Questo articolo descrive uno studio, realizzato con la metodologia Delphi, sulle tendenze nel settore di ricerca del Technology Enhanced Learning (TEL). Lo studio stato condotto nell\u2019ambito delle attivit della Rete di Eccellenza Europea STELLAR ...
International Journal of Computer-Supported Collaborative Learning Vol. 7, No. 2 (June 2012) pp. 307–339
With the aim to promote students' mathematics learning, we extended the Cognitive Tutor Algebra (CTA), a computer-based tutoring system for high school mathematics, to a collaborative setting. Furthermore we developed a collaboration script to...
Are Two Heads Always Better than One? Differential Effects of Collaboration on Students' Computer-Supported Learning in Mathematics
International Journal of Computer-Supported Collaborative Learning Vol. 6, No. 3 (September 2011) pp. 421–443
While some studies found positive effects of collaboration on student learning in mathematics, others found none or even negative effects. This study evaluates whether the varying impact of collaboration can be explained by differences in the type...
International Journal of Computer-Supported Collaborative Learning Vol. 4, No. 1 (March 2009) pp. 69–92
In an earlier study, we had tested if observing a collaboration model, or alternatively, following a collaboration script could improve students' subsequent collaboration in a computer-mediated setting and promote their knowledge of good...
International Journal of Computer-Supported Collaborative Learning Vol. 2, No. 1 (March 2007) pp. 63–86
The analysis of the process of collaboration is a central topic in current CSCL research. However, defining process characteristics relevant for collaboration quality and developing instruments capable of assessing these characteristics are no...
Learning to Collaborate: An Instructional Approach to Promoting Collaborative Problem Solving in Computer-Mediated Settings
Journal of the Learning Sciences Vol. 14, No. 2 (2005) pp. 201–241
Effective collaboration in computer-mediated settings among spatially distributed people is a precondition for success in many new learning and working contexts but it is hard to achieve. We have developed two instructional approaches to improve...
