Experience shows that testing students’ understanding of new concepts immediately after they have been introduced considerably improves the learning process. In this work understanding of a concept is assumed to take place if a student can provide reasonably correct answers to questions requiring application this concept. A possible solution to the problem of how to determine whether students actually understand a concept is to give them tests. Such tests, being a part of an intelligent system, provide inconsistent information to intelligent agents, facilitating the tests evaluation process. This happens because the degree of a student’s understanding varies a lot depending on factors like time and the way questions are formulated. Since classical logic fails to draw conclusions in the presence of inconsistencies we propose application of paraconsistent logic.
