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. The instrument is provided as a diagnostic question instrument in the form of a description. Based on data analysis, it is found that it is valid and reliable so that it can be used for research. The proportions of the resulting answers, namely there are four answer choices and four reason choices with portions right, right with a little wrong, right with many wrong answers or reasons. Based on the results of the analysis of misconceptions, it is known that 23.7% of students answered correctly, 6, 3% of students guessed the answer, 38 % of students had misconceptions and 31.6% of students did not understand the concept.

In the preliminary study stage based on the computational thinking (CT) test given, it is known that the CT ability of students is at the level of the algorithm, students are able to provide answers but have not been able to explain in detail
Summary
Penelitian ini bertujuan untuk mengembangkan soal diagnostic dalam mengukur miskonsepsi mahasiswa dan mendeskripsikan profil miskonsepsi yang dialami mahasiswa pada mata kuliah konsep sains sub bab Sistem Gerak. Penelitian ini merupakan bagian dari langkah penelitian dan pengembangan (R & D) dalam mengembangkan soal tes diagnostic jenis four tier yang terdiri atas tahap studi pendahuluan, tahap pengembangan dan tahap validasi. Instrumen yang diberikan yaitu instrument soal diagnostic berbentuk uraian. Berdasarkan analisis data, diperoleh hasil bahwa soal bersifat valid dan reliable sehingga dapat digunakan untuk penelitian. Proporsi jawaban yang dihasilkan yaitu ada empat pilihan jawaban dan empat ilihan alasan dengan porsi benar, benar dengan sedikit salah, benar dengan banyak salah dan jawaban maupun alasan salah.Berdasarkan hasil analisis miskonsepsi, diketahui bahwa 23,7% mahasiswa mejawab dengan benar, 6,3% mahasiswa menebak jawaban, 38,% mahasiswa mengalami miskonsepsi dan 31,6% mahasiswa tidak paham konsep
