Abstract

This research aims to the development of a Four-Tier Open-ended Momentum and Impulse Instrument
(FOTMI) using Rasch analysis and identifies students misconceptions. This research method uses the 4D model
(Defining, Designing, Developing, and Disseminating). The development of this diagnostic test consists of 10 multiple
choice questions with open-ended questions given to high school students with 30 students^ participating in grade 11 (7
male students called ^Lanang^ and 23 female students called ^Wadon^), the average age was 16 years old. The
development of a close-ended four-tier instrument is based on the students answers to FOTMI. The analysis results
obtained that FOTMI is a valid and reliable instrument to identify misconceptions. The results of the identification of
misconceptions in participants found that the highest misconceptions occurred at number 7 that was 57% and the lowest
misconceptions of 13% occurred at numbers 2.
