摘要

In interactive learning environments based on visual representations the problem of checking the correctness of student solutions is much harder than with linear textual or numerical input. This paper presents a generic approach to providing learner feedback in such environments. The underlying checking mechanism analyzes system states against target constellations defined as sets of constraints about locations or connections of objects. A newly introduced analysis graph allows also the definition of procedural dependencies. An implementation of a feedback mechanism for traffic education in secondary schools is presented as an example.
