Teachers are no longer just lecturers transmitting their knowledge, they are now mentors as well.

   The advantage of IT in knowledge assessment lies not only in the fact that it liberates the professor or teacher from long and tedious examination or that it enables the students to get the test results quickly, but in the fact that it introduces completely new characteristics into the processes of learning and knowledge assessment. Interactivity, use of multimedia and a computer-mentor who is always there and ready to provide help with learning, are some of those characteristics.  They radically change the role of the professor from a mere tutor who transmits content to students, to a mentor who helps and guides students through the learning process. In this environment even the traditional methods of summative knowledge assessment lose their importance and become just one part of a very complex strategy of continuous and varied assessments of goal attainment in online courses.
