Cooperative Student Modelling in a Hypermedial Web-based Environment

The present paper focuses on a web-based environment implementing our cooperative modeling system, COSMO. COSMO was presented in previous works and consists of a system, which carries out active cooperative student modeling, building up the student model as a result of a joint tutor-student assessment. To do this, it makes a calculation of the student's self-assessment ability and then attributes variable weights to the tutor and student's assessments according to the student's estimated self-assessment ability. The system is able to update and modify the student model continually during use. Herein we describe the architecture and the various components of a hypermedial web-based environment to be able to use the COSMO model
