Using Formal Concept Analysis in the Evaluation Process
Formal Concept Analysis (FCA) is a framework of knowledge processing and knowledge representation based on order and lattice theory. FCA methods can be adopted successfully in numerous areas of pedagogical work. This paper focuses on methods that can help teachers in the evaluation process. When a teacher evaluates a test, the results of the students are presented in a student assessment table. We create a question skill table as well, which shows the learning skills needed to answer the questions of the test. Combining these matrices, we construct a formal context and using its concept lattice we can make a deeper analysis of the test results. The obtained concept lattice visualizes the knowledge hierarchy of the class and the teacher can immediately determine the knowledge level of the class and its members individually.
