Using Bayesian Networks for Learning Analytics in Engineering Education: A Case Study on Computer Science Dropout at UCLM

摘要

Student dropout in Engineering Education is an important problem which has been studied from different perspectives and using different techniques. This manuscript describes the methodology used to address this question in the context of learning analytics, using Bayesian networks because they provide adequate methods for the representation, interpretation and contextualization of data. The proposed approach is illustrated through the case study of the abandonment of Computer Science (CS) studies at the University of Castilla-La Mancha, which is close to 40%. To that end, several Bayesian networks were obtained from a database containing 363 records representing both academic and social data of the students enrolled in the CS degree during four courses. Then, these probabilistic models were interpreted and evaluated. The results obtained revealed that the great heterogeneity of the data studied did not allow to adjust the model accurately. However, the methodology described here can be taken as a reference for other works where a less heterogeneous database could be obtained, aimed at analysing student characteristics from a database.
