IDENTIFIKASI MISKONSEPSI MATERI MOMENTUM DAN IMPULS MENGGUNAKAN INSTRUMEN FOUR-TIER DIAGNOSTIC TEST WITH CERTAINTY OF RESPONSE INDEX BERBASIS JOTFORM

IDENTIFICATION  MISCONCEPTIONS OF MOMENTUM AND IMPULSE MATERIAL USING FOUR-TIER DIAGNOSTIC TEST WITH CERTAINTY OF RESPONSE INDEX BASED ON JOTFORM

Penguasaan dan pemahaman konsep menjadi penentu keberhasilan pembelajaran Fisika. Dengan demikian, identifikasi konsepsi peserta didik perlu dilakukan dalam pembelajaran Fisika sebagai bahan evaluasi untuk mengembangkan upaya reduksi miskonsepsi peserta didik. Oleh karena itu penelitian ini bertujuan untuk menganalisis kualitas instrumen four-tier diagnostic test with CRI berbasis JotForm dan mendeskripsikan profil miskonsepsi peserta didik MAS Muhammadiyah 1 Paciran pada materi momentum dan impuls. Kualitas instrumen ditinjau dari validitas dan reliabilitasnya. Penelitian ini menggunakan metode ADDIE (Analysis, Design, Development, Implementation, and Evaluation). Perancangan dan pengembangan instrumen dilakukan pada tahap analysis, design, dan development. Pemotretan profil dan penyebab miskonsepsi peserta didik dilakukan pada tahap Implementation dan Evaluation. Penelitian ini menghasilkan kualitas instrumen four-tier diagnostic test with CRI momentum dan impuls berbasis JotForm berdasarkan validitas teoritis mencapai 89,29%, pada ranah isi mencapai 81%, ranah konstruk 88%, dan ranah bahasa 98%, dengan Percentage of Agreement sebesar 96%. Berdasarkan validitas empiris isi diperoleh persentase  sebesar 6,93% dan  sebesar 6,53%. Berdasarkan validitas empiris konstruk dengan taraf signifikansi 0,05 ditemui  senilai 0,273 sehingga dari 15 soal yang disajikan diperoleh 12 soal yang valid secara empiris konstruk dengan skor reliabilitas . Dalam penelitian ini didapati bahwa 3 peserta didik mengalami miskonsepsi rendah, 14 peserta didik miskonsepsi sedang, dan 6 peserta didik miskonsepsi tinggi. Selain itu, didapati penyebab miskonsepsi peserta didik didominasi oleh false positif dan pemikiran humanitif sebesar 28,56%. Dapat disimpulkan bahwa instrumen yang dikembangkan dalam penelitian ini valid dan reliabel serta dapat digunakan untuk identifikasi profil dan penyebab miskonsepsi peserta didik.

Mastery and understanding of concepts determine the success of learning, including in physics. Thus, identification of students' conceptions needs to be done in physics learning as an evaluation material to develop efforts to reduce misconceptions in students. Therefore, this study aims to analyze the quality of the four-tier diagnostic test instrument with CRI based on JotForm and describe the misconception profile of MAS Muhammadiyah 1 Paciran students on momentum and impulse material. The quality of the instrument is reviewed based on its validity and reliability. This research uses the ADDIE method (Analysis, Design, Development, Implementation, and Evaluation). Instrument is carried out at the analysis, design, and development stage. Capturing the profile and causes of students' misconceptions was carried out at the implementation and evaluation stages. This study resulted in the quality of the four-tier diagnostic test instrument with CRI momentum and impulse based on theoretical validity reaching 89.29%, in the content domain reaching 81%, construct  88%, and language 98%, with a percentage of agreement of 96%.  Based on the empirical validity of the content, the percentage of FP is 6.93% and FN is 6.53%. Based on the empirical validity of the construct with a significance level of 0.05,  was found to be 0.273, so of the 15 questions presented, 12 were empirically valid constructs and obtained a reliability score of . In this study, it was found that 3 students had low misconceptions, 14 students had medium misconceptions, and 6 students had high misconceptions. In addition, it was found that the cause of students' misconceptions was dominated by false positives and humanistic thinking by 28.56%. It can be concluded that the instrument developed in this study is valid and reliable and can be used to identify the causes of students' misconceptions.
