Data Pre-processing and Data Generation in the Student Flow Case Study

Abstract: Education covers a range of sectors from kindergarten to higher education. In the education system, each grade has three possible outcomes: dropout, retention and pass to the next grade. In this work, we study the data from the Department of Statistics of Education and Science (DGEEC) of the Education Ministry. DGEEC maintains those outcomes for each school year, therefore, this study seeks a longitudinal view based on student flow. The document reports the data pre-processing, a stochastic model based on the … Show more

“…This work follows on from the _IABE maturity model [5] using the ModEst project data [8,9] as a test case. This work's main contribution is applying the _IABE model to the DGEEC dataset by defining different wh-questions for each maturity model level and using the most appropriate techniques to obtain the answers.…”

“…Each entry concerns a student's enrollment in a specific school year, with information detailing the characteristics of the enrollment and its outcome. The DGEEC has annual data, and the ModEst project is interested in having a longitudinal view of the data [8]. So, it is necessary to correctly perceive how a student's path through the education system changes and what events are associated with them.…”
