Using formal concept analysis to explore hidden knowledge in the assessment of amath course

Abstract

Since the emergence of COVID-19, online teaching and e-Learning has become essential in education. Actually, in at our University, we have had to move to a complete online teaching framework through the Moodle e-learning system. As a result, we have had to deploy new material as videos in Youtube channels, newexercises, tasks, live teaching, etc that have generated a huge amount of data that contains interesting information. In particular, we have used randomly generated exams from a bank of quizzes to evaluate the students. In this paper, we analyze the results of these quizzes using Formal Concept Analysis tools in order to check the hidden knowledge in the assessment process with the goal of improving the developed material for next years. In addition, we will analyze how the different exercises and tests relate to each other so that we can use this information in the following courses to improve our lectures.
