CLASSIFICATION NEEDS TEACHERS USING ALGORITHM C4.5

Abstract

The problem in education is the lack of teachers , the teachers are not in accordance with the educational background ( mismatch ) , low qualifications , competence disparities , and the uneven distribution of teachers . This study aims to ( 1 ) To design a classification algorithm model distribution needs of teachers by using C4.5 algorithm ( 2 ) the accuracy of the model for equalization algorithm C4.5 to teachers' needs . This study is a historical research using experimental methods is to perform design and modeling systems . Data was collected through library research methods ( library research ) and methods of data collection (field research ) and application development based on analysis of the results of data mining methods the algorithm C4.5 . The results of this study is the classification of state information needs of teachers of subjects is more , or less enough at each school . C4.5 algorithm accuracy rate reaches 83 % .
