: The Effect of the Use of Motion Demonstrations on the Frequency of Misconceptions of High School Students on the Topic of Motion Kinematics

Abstract

Penelitian ini bertujuan untuk menentukan pengaruh penggunaan peragaan gerak terhadap frekuensi miskonsepsi siswa pada topik kinematika gerak. Metode penelitian yang digunakan adalah eksperimen dengan desain One Group Pretest-Posttest. Populasi penelitian adalah siswa kelas XI-Fisika di SMA Negeri 1 Telaga Biru pada tahun ajaran 2024/2025. Sampel penelitian terdiri dari tiga kelas yang dipilih secara acak, yaitu kelas XI Fisika 6 sebagai kelas eksperimen, serta kelas XI-Fisika 1 dan XI-Fisika 2 sebagai kelas replikasi. Analisis data meliputi statistik deskriptif untuk menggambarkan karakteristik data, serta statistik inferensial, termasuk uji hipotesis dan analisis n-gain. Hasil analisis data menunjukkan penurunan frekuensi miskonsepsi yang signifikan setelah penerapan peragaan gerak. Rata-rata frekuensi miskonsepsi siswa menurun dari 9,57 menjadi 2,8 di kelas eksperimen, dari 8,17 menjadi 2,3 di kelas replikasi 1, dan dari 5,87 menjadi 1,1 di kelas replikasi 2. Uji hipotesis mengkonfirmasi adanya perbedaan signifikan dalam frekuensi miskonsepsi antara Pretest dan Posttest di ketiga kelas. Analisis n-gain menunjukkan peningkatan pemahaman konsep yang tinggi, dengan nilai 0,71 di kelas eksperimen, 0,75 di kelas replikasi 1, dan 0,72 di kelas replikasi 2.This study aims to determine the effect of using motion demonstrations on the frequency of students\u27 misconceptions in the topic of motion kinematics. The research employed an experimental method with a One Group Pretest-Posttest design. The population was class XI-Physics students at SMA Negeri 1 Telaga Biru in the 2024/2025 academic year. The sample consisted of three classes selected randomly, class XI Physics 6 as the experimental class, and classes XI Physics 1 and XI Physics 2 as replication classes. Data analysis involved descriptive statistics to characterize the data, and inferential statistics, including hypothesis testing and n-gain analysis. The results of the data analysis showed a significant decrease in the frequency of misconceptions after the application of motion demonstrations. The average frequency of student misconceptions decreased from 9.57 to 2.8 in the experimental class, from 8.17 to 2.3 in replication class 1, and from 5.87 to 1.1 in replication class 2, indicating a significant reduction. Hypothesis testing confirmed a significant difference in misconception frequency between the Pretest and Posttest across all three classes. The n-gain analysis revealed a high improvement in concept understanding, with values of 0.71 in the experimental class, 0.75 in replication class 1, and 0.72 in replication class 2
