Abstract:
For almost two centuries educators and technicians have been designing and evaluating teaching devices having the capability to coach, support learning processes and to asses the student's mastery of new skills by means of tests and exercises. Without a personal tutor, 'paper and pencil" exercises follow a presentation-activation-feedback pattern that takes days before the Student receives feedback on her Performance. The concept of an automated tutor that conveys exercises (presentation), demands a response (activation), and then informs the student Df the correctness
of her response (feedback), aims to replace the linear activation-feedback phase by an interactive process that allows the student :o makeintelligent adjustmentsbased on available feedback.
In a suitable domain of knowledge the techniques developed in this thesis lead to an effective automated tutor, able to reliably and quickly check details, and to provide feedback just in time—freeing tie human tutor to address more demanding and thought-stimulating activities. The key idea is to design both a class of exercises and a Solution spacs within which the student's Solution is confined. This is possible in selected mathematically
structured domains of knowledge where Solutions and their processes can be verified algorithmically.
The validity of this approach is demonstrated in our system ExorCISER, which contains 25 examples of such interactive exercises and which has been in use for several years. We have tested the usability and verified the effectiveness of Exerciser in actual instructional settings by means of a comparative study.
The opportunity to receive immediate individual feedback, together with the possibility of generating an unlimited number of exercise instances of various levels of difficulty, combined with the possibility to look at the Solution of an exercise on request, makes ExORClSER'steaching capabilities truly interactive and attractive. Further reasons for the student's acceptance of the Exorciser environment is its intuitive user interface and the fact that the student always maintains control of the system.
