Student Assesment in a Technological Framework Fabrizio Iozzi (Universit`a Bocconi, Istituto di Metodi Quantitativi, Milano, Italy) Following one year's experience of lecturing Calculus to undergraduate students at Universit` Bocconi, Milan, Italy, we have investigated the way students collaborate among themselves and with the lecturers when using an e-learning software (for further information see also the papers by M. Impedovo and G. Osimo); then we studied several approaches to the problem of the assessment of students' knowledge. In the first part we have focused on the subjects (which are the preferred topics among students and why), the way the discussions are brought on (which kind of discussions are more popular and how the students discuss the subjects) and the impact of the discussions on the performances of the students (are they related to the way the students are involved in the collaborative environment?). In the second part of this research, three methods to assess students' performances have been compared: a particular mathematical software, the evaluation sections of an e-learning software and a software, developed by the author, specifically designed for lecturers. In the latter case, the technological framework is explained in detail. In particular we discuss: a) the choices made for the interface; b) the intranet set up to guarantee maximum security before, during and after the examination and c) the modularity of the software developed. We consider these aspects interesting by themselves and because the problems they pose are too often neglected.
