Hows and whys in online assessment

In this work, the authors aim at presenting some conclusions regarding e-assessment strategies based on some of the research done on the way the curricular component of the Master's Course on Multimedia in Education, of the University of Aveiro, has been developed. The focus is on the description of strategies that were used to assess students in this particular online environment, i.e. the way they were put into practice (How?) and the advantages of using them (Why?). Some reflections are also made upon the constraints and potentialities of e-assessment, inherent to the environment where it occurs.
