Concepts in fuzzy logics

In this paper we present a method for early identification of students who would have serious difficulties in studying a particular subject due to lack of preliminary knowledge. Methods from formal concept analysis are applied for finding relationships between results from a test on students' preliminary knowledge and the outcome of learning new knowledge within the same subject. Fuzzy logic rules are further incorporated into the process of establishing level of difficulties a student would have while learning new concepts and skills within a particular topic in that subject.
