APLIKASI RASCH MODEL: PENGEMBANGAN INSTRUMEN TES UNTUK MENGUKUR MISKONSEPSI MAHASISWA PADA MATERI MEKANIKA

Abstract

The purpose of this research is to find out the feasibility of misconception test instruments on mechanical material using the rasch model on Physics Education Study Program Students at Sultan Ageng Tirtayasa University Even Semester 2018-2019. This research uses the R & D (Research and Development) method. The results showed that the misconception test instruments developed were feasible to use with regard to the criteria based on the Rasch model application. The validity of the construct of the item instrument was developed so that it obtained a level of conformity between the response of students and the test instrument, 10 items developed, entered into the good or accepted category so that it was concluded that there was no misconception from the students on the items, the results were 0, 57 in the weak category and reliability of the questions obtained enough results of 1.53, students with codes A0, A1, A2, A2, A2, A2 & A3 with +2 logit values, indicate that some students already understand the concepts that have been tested , in the middle ability with +1 logit value and also there are three students with low ability with logit -2 value which means that there are still some students who still misconcept about the material concept being tested.
