Abstract

The objectives of research are to develop and to determine the validity of the instrument by testing the test of students who have studied chemical bonding material. Test of empirical validity was analyzed using the Rasch model. Decision making based on MNSQ Infit and MNSQ Outfit values. The instrument test consists of 20 questions in the form of a description given to 116 students who are outside the study sample. The results showed that there were 18 valid questions and 2 invalid questions. The invalid question is declared not suitable to be used for the purpose of further analysis.
