Abstract

Concept understanding is very important in the learning process. Understanding the correct concept has an impact on learning outcomes. This research uses the R & D method which aims to develop misconception detection instruments and produce products in the form of four-tier design misconception detection instruments and see the feasibility of the product. The quality of the instrument was tested by testing the validity of the expert judgment, test questions in the form of validity and reliability tests. The question with valid criteria is 9 questions with moderate reliability. For the feasibility of the instrument, the percentage is 84% with very decent criteria.
