Formative Evaluation of the SIETTE collaborative Testing Environment

This paper describes the development of a computerized collaborative testing environment upon the SIETTE system. Using this environment, students can take a test in groups. They can exchange messages, view the answers of their peers and discuss about the correct answer. We have made a formative evaluation of the system from March 2005 to January 2008. The incidences happened during the experiments and the users’ feedback, have been used to improve the system. During these years, three different prototypes have been released and tested with undergraduate students from two Spanish Universities.
