Abstract

Penelitian ini bertujuan untuk menganalisis miskonsepsi siswa pada materi sistem periodik unsur terfokus konsep sifat keperiodikan unsur melalui pengembangan instrumen tes diagnostik Three-Tier Multiple Choice Test. Metode penelitian yang digunakan ialah metode R&D dan model yang digunakan dalam penelitian ini ialah model 4D. Subjek dalam penelitian ini ialah siswa kelas X SMA Pangudi Luhur Don Bosko. Hasil penelitian menunjukkan validitas dan reliabilitas pada uji coba skala kecil dan uji coba skala besar berturut-turut, yaitu 0,87; 0,74 dan 0,86; 0,82. Profil pemahaman konsep siswa secara keseluruhan menunjukkan siswa yang termasuk dalam kategori Paham Konsep 44%, Paham Konsep Kurang PD 23% Kurang Paham Konsep 4%, Tidak Paham Konsep 61%, Miskonsepsi Positif 18%, Miskonsepsi Negatif 21%, dan Miskonsepsi Penuh 23%. Siswa dan guru juga memberikan respon yang positif melalui angket tanggapan. Berdasakan hasil penelitian, maka dapat disimpulkan bahwa instrumen tes diagnostik Three-Tier Multiple Choice Test yang dikembangkan layak, valid, reliabel, dan praktis untuk mendiagnosis miskonsepsi siswa pada materi sistem periodik unsur terfokus sifat keperiodikan unsur.

Abstract

This study examines the effectiveness of the numeracy-visual integrative learning method in improving students' understanding of chemical equilibrium. The subjects of the study consisted of 42 students from Lanny Jaya and Nduga, Papua. A quasi-experimental method with pre-test and post-test was used to measure the increase in understanding. The results showed a significant increase from an average pre-test score of 45.2 to 78.6 on the post-test (t(41) = 12.35, p < 0.001). Students' responses to this method were positive, with an average score of 4.3 out of 5 based on a Likert scale questionnaire. Some of the obstacles faced were limited access to technology and initial difficulties in understanding graphs. Overall, this method is effective in improving understanding of the concept of chemical equilibrium and can be applied in areas with limited learning resources.
