Abstract
A $TWiM$ system for tutoring logic programming is described. $TWiM$ assists
students who know basics of Prolog language to learn list processing
predicates. It is written in Prolog and employs $WiM$ learner If a student's
answer is incorrect, the student may ask the system for hints. An instance of
the intended program that is not covered by the student answer is one of
hints. The student may, too, type an example (positive or negative).
Afterwards $TWiM$ revises the student's program, employing $WiM$, and
displays a new solution. Next, the student itself has to decide if the new
solution is correct. Each hint, depending on its kind, decreases the
student's evaluation.
