Abstract

Miskonsepsi adalah pemahaman konsep yang terdapat didalam pikiran siswa yang bertentangan dengan konsep ilmiah. Suatu miskonsepsi yang terjadi tidak seharusnya dibiarkan karena berkemungkinan besar siswa akan mengalami miskonsepsi kembali pada konsep yang lebih kompleks. Laju reaksi materi yang yang bersifat abstrak dan membutuhkan pemahaman konseptual. Untuk itu perlu diterapkan model yang dapat mengatasi miskonsepsi siswa yaitu model Problem Based Learning dan model Project Based Learning. Tujuan penelitian ini untuk membandingkan model mana yang paling baik dalam mereduksi miskonsepsi siswa pada materi laju reaksi. Jenis penelitian adalah quasi experiment, dengan desain penelitian menggunakan 1 kelas kontrol (menggunakan model Discovery Learning) dan 2 kelas eksperimen (menggunakan model Problem Based Learning dan model Project Based Learning). Untuk mengukur miskonsepsi siswa menggunakan instrumen four-tier diagnostic test. Sasaran penelitian adalah siswa kelas XI SMAN 3 Jambi. Data penelitian dikumpulkan melalui pretest dan postest. Uji hipotesis dilakukan dengan diawali dengan uji normalitas dan homogenitas terlebih dahulu, dilanjutkan dengan uji ANOVA satu jalur. Hasil uji ANOVA menunjukkan terdapat perbedaan miskonsepsi siswa antara kelas yang menggunakan model Discovery Learning, model Problem Based Learning dan model Project Based Learning. Berdasarkan penelitian yang telah dilakukan dapat disimpulkan bahwa model Discovery Learning belum dapat mereduksi miskonsepsi siswa, sedangkan model Problem Based Learning dan model Project Based Learning dapat mereduksi miskonsepsi siswa. Model Problem Based Learning mampu menurunkan miskonsepsi siswa sebesar 9% dan model Project Based Learning mampu menurunkan miskonsepsi siswa sebesar 15,6%. Misconceptions are understanding concepts contained in students' minds that conflict with scientific concepts. A misconception that occurs should not be allowed because there is a big possibility that students will experience the misconception again on a more complex concept. The reaction rate of matter is abstract and requires conceptual understanding. For this reason, it is necessary to apply a model that can overcome student misconceptions, namely a model Problem Based Learning and model Project Based Learning. The aim of this research is to compare which model is best in reducing students' misconceptions about reaction rate material. The type of research is like an experiment, with a research design using 1 control class (using model Discovery Learning) and 2 experimental classes (using the model Problem Based Learning and model Project Based Learning). To measure student misconceptions using instruments four-tier diagnostic test. The research targets were class XI students of SMAN 3 Jambi. Research data was collected through pretest and posttest. Hypothesis testing was carried out by starting with normality and homogeneity tests first, followed by a one-way ANOVA test. The results of the ANOVA test show that there are differences in student misconceptions between classes that use the model Discovery Learning, model Problem Based Learning and model Project Based Learning. Based on the research that has been carried out, it can be concluded that the model Discovery Learning has not been able to reduce students' misconceptions, while the model Problem Based Learning and model Project Based Learning can reduce student misconceptions. Model Problem Based Learning able to reduce student misconceptions by 9% and model Project Based Learning able to reduce student misconceptions by 15.6%
