Özet:
Education Management Information Systems have been going under direct mutation in Turkey during last decade. In this manner, educational data mining becomes very essential to be discussed with the data gathered by those systems. In this study, a web based decision support system (WBDSS) is designed with multiple linear regression algorithm for the department selection process of vocational high schools by the help of the individual correlation between 9th level courses and 10th level departmental and common courses of students. The main knowledge discovery sequences of data mining have been applied to the methodology of WBDSS and the system is implemented by the data gathered from Bahçelievler Vocational Trade High School. As a result of the research a combination between E-Okul and WBDSS is found to be remarkable for best implementation and evaluation purposes.
