Recently, teaching evaluation is defined the main part of quality in education. The students normally make answers on questionnaire that are divided into types; close-end question and open-end question. The close-end question is simple answer as multi-choices that are easily processed by statistical evaluation.

The techniques extract classification of attitudes that are defined positive and negative attitude from students to instructor for improvement of learning and teaching.
