“…Therefore, student's misconception should be detected earlier to prevent misconceptions in subsequent concepts. To do that, a conception diagnostic test is required, either using interviews, concept maps or multi-tiers conception diagnostic test (Wiyono et al, 2016).…”

Abstract Misconceptions has commonly found in Physics concepts, including in Vector concepts. For example, students assumed when an object moves at a certain path and returns to the original position using different path, the displacement is not zero. Meanwhile, according to the Vector concept, the object displacement is zero when it moves and returns to the original position. This discrepancy is called misconception. Such misconception needs to be identified. One of them is by multi-tiers conception diagnostic test. This study was aimed to develop a five-tier conception diagnostic test for Vector concepts and determine the validity (both internal and external aspects) and the reliability. Two groups of students were involved in this work: 25 students to collect common reasons (three-tier questions) and 65 students to calculate the validity and reliability scores. The internal validity was justified by two pointed lecturers at Physics Dept. UNESA. The external validity contains content and construct aspects. The content aspect was determined based on false positive (FP) and false negative (FN) scores, each should be <10%. The construct aspect was calculated by the Pearson’s product-moment correlation. The reliability was determined using Alpha Cronbach with = 0.244 and 5% significance level. The internal validity score = 95%, the FP and FN scores = 3.5 and 9.0% respectively which means that the developed instrument is valid. The = 0.656 and = 0.898 which are > rtheoritic. Therefore, the developed instrument is valid and reliable to diagnoses student’s conception on the Vector concepts. Keywords: Vector concepts, five-tier conception diagnostic test, validity, reliability Abstrak Miskonsepsi, secara umum, banyak ditemukan pada konsep Fisika, termasuk pada konsep-konsep Vektor. Sebagai contoh, peserta didik (PD) menganggap apabila suatu benda bergerak pada lintasan tertentu dan kembali pada posisi semula melalui lintasan lain, maka perpindahan tersebut tidak nol. Sementara menurut konsep Vektor, perpindahan suatu benda dikatakan nol apabila benda tersebut bergerak dan kemudian kembali pada posisi semula. Perbedaan keduanya disebut miskonsepsi. Miskonsepsi seperti itu perlu diidentifikasi. Salah satunya adalah dengan tes diagnostik konsepsi multi-tier. Penelitian ini ditujukan untuk mengembangkan sebuah tes diagnostik konsepsi berformat five-tier untuk konsep Vektor dan menentukan tingkat validitas dan reliabilitasnya. Dua kelompok PD dilibatkan dalam pekerjaan ini, yaitu 25 PD untuk menjaring alasan yang umum dikemukakan oleh siswa (pertanyaan three-tier) dan 65 PD untuk menghitung skor validitas (baik aspek internal maupun eksternal) dan reliabilitas tes tersebut. Validitas internal diuji oleh dua dosen Jurusan Fisika UNESA yang ditunjuk. Validitas eksternal terdiri dari aspek konten dan konstruk. Aspek konten ditentukan berdasarkan skor false positive (FP) dan false negative (FN), dimana tiap skor tersebut harus <10%. Aspek konstruk dihitung dengan persamaan korelasi Pearson Product Moment . Reliabilitas ditentukan menggunakan Alpha Cronbach dengan = 0.244 dan taraf signifikasi 5%. Skor validitas internal = 95%, skor FP dan FN masing-masing = 3.5 dan 9.0% yang berarti bahwa instrumen yang telah dikembangkan ini valid. Nilai = 0.656 dan = 0.898 yang nilainya > rteori. Karena itu, instrumen ini valid dan reliabel untuk dipergunakan untuk mendiagnosis konsepsi PD pada konsep-konsep Vektor. Kata kunci: Konsep-konsep Vektor, five-tier diagnostic test, validitas, reliabilitas

“…Misconception category 3 (M3) was identified as the highest misconception of this indicator with a presentation of 42.22% or as many as 38 students. In line with Wiyono et al (2016) research, students have misconceptions, students assume that objects will maintain their initial position that moves by giving new movements in the opposite direction. The identified misconception of category 2 (M2) was 17.78%, or Alatas, F., Ilhamiah, S., Suryadi, A.…”

IDENTIFIKASI MISKONSEPSI SISWA MENGGUNAKAN UJI ISOMORFIK: KASUS HUKUM NEWTON TENTANG GERAKAbstractStudents' misconceptions can lead to learning failure if they are not addressed. In this study, using Google Form, we identify students’ misconceptions using the isomorphic test method on Newton's Law of Motion, especially the principles of dynamics. This study is quantitative research conducted in three junior high schools in South Tangerang. There are 90 participants involved that was selected by purposive sampling method. The research instrument was an isomorphic test in form of multiple choice with nine questions with three indicators namely: analyzing the application of Newton’s I law in daily life; analyzing the correlation between force and mass and the acceleration of a moving object; and analyzing the application of Newton’s III Law in daily life. The results showed that the students were identified as having misconceptions in Newton’s Law concept using isomorphic tests, including misconceptions of inertia and misconceptions of Newton’s Third Law of Motion. One of the misconceptions is that students assume an object will maintain its initial position in motion by applying a new force in the opposite direction. The students' misconceptions found in this study can be used as a reference so that they can be overcome in the learning process.AbstrakMiskonsepsi dapat menyebabkan siswa sulit belajar jika tidak segera diatasi. Dalam penelitian ini, dengan menggunakan Google Form, kami mengidentifikasi miskonsepsi siswa menggunakan instrumen tes isomorfik pada materi Hukum Newton tentang gerak, khususnya pada prinsip-prinsip dinamika. Studi ini merupakan penelitian kuantitatif yang dilaksanakan di tiga SMP di Tangerang Selatan. Terdapat 90 partisipan yang dilibatkan yang dipilih dengan metode purposive sampling. Instrumen penelitian berupa tes isomorfik berupa pilihan ganda dengan sembilan soal dengan tiga indicator yaitu menganalisis penerapan hukum I Newton dalam kehidupan sehari-hari; menganalisis hubungan antara gaya dan massa dengan percepatan suatu benda yang bergerak; dan menganalisis penerapan Hukum 3 Newton dalam kehidupan sehari-hari. Hasil penelitian menunjukkan bahwa siswa teridentifikasi mengalami miskonsepsi pada konsep Hukum Newton. Diantara miskonsepsinya adalah siswa berasumsi bahwa benda akan mempertahankan posisi awalnya dalam gerak dengan memberikan gaya baru dalam arah yang berlawanan. Miskonsepsi siswa yang ditemukan dalam studi ini dapat menjadi referensi sehingga dapat diatasi dalam proses pembelajaran.

Misconceptions often occur, especially in chemical material like stoichiometry which are full of abstract concepts. The purpose of this study was to determine the feasibility of mistion software to detect and reduce misconceptions in stoichiometric material with conceptual change text strategy. This research was conducted using the Research and Development (R&D) method with 15 students of SMAN 1 Gedangan as research subjects. Software is developed using Adobe Flash CS 6 with action script 3.0. The software's feasibility is viewed from the validity practicality, and effectiveness. The data analysis results show that 1) the software is very valid with the average result of content validation is 93.52%, and the construct validation is 91.82%. 2) The software is very practical, with an average result of student response questionnaires is 95.28% and supported with the average result of student observations is 85%. 3) Software is effective with the average result of misconception shift for sub-concept basic chemical law is 77.27% with effective category, sub-concept of reaction equation is 85.05% with very effective category, and sub-concept of mole is 73,72% with effective category. Based on the result, we can conclude that mistion software is feasible to detect and reduce students' misconception.
