Diagnostic Test Profile of Scientific Literacy to Measure Student’s Misconceptions in Science Concept Course

Abstract

Abstract This study aims to develop diagnostic questions in measuring student misconceptions and to describe the profile of the misconceptions following students in the science concepts subject in the Motion Systems sub-chapter. This research is part of the research and development (R&D) step in developing a four-level type of diagnostic test item consisting of a preliminary study stage, a development stage, and a validation stage. At this stage of development, the researcher gave open description questions to students of the Primary Educational Teacher Department, Universitas Muria Kudus in semester 3 of the 2018/2019 academic year classes 3C, 3D, 3E, and 3F to find the form of diagnostic questions, find answer options and options for these questions.
