Title: A Review on Predicting Student Graduation in Higher Education Using Data Mining
Abstract: Data Mining is increasingly used in higher institution to discover valuable information particularly in student databases. It brings to the concept of Educational Data Mining (EDM). EDM is a field that analyzes educational data to resolve its research issues using statistical, machine learning, and data mining algorithms. The emergence of EDM creates a good environment to all stakeholders in higher institution. One of them is graduation information. The data of graduated students from each academic year is an important source of information used as indicators of the school effectiveness by state and federal governments and accrediting agencies. Therefore, data mining can be used as an effective tool to predict graduation information of students to give insights to all stakeholders in higher institution whether the students are able to graduate on time, fast, late or even drop out from school. As a result, it assists the students on selecting suitable courses or field of study to their successful academic paths. In addition, it also assists the instructors to organize the curricula more effective to improve student academic performance. The purpose of this presentation is to provide an overview on data mining techniques that have been used to predict graduation information in higher institution through a survey of literature.
