标题：Elicit-Predict-Confront-Observe-Explain-Reinforce (EPCOER) Learning on Thermochemistry to Reduce Alternative Concept among Students with Different Initial Knowledge
摘要：Penelitian ini bertujuan untuk mereduksi konsep alternatif siswa dengan model pembelajaran
EPCOER dan model pembelajaran POE pada materi termokimia. Penelitian ini menggunakan instrumen
tes berupa three tier test yang memiliki validitas isi 98% dengan kriteria sangat baik dan koefisien
reliabilitas Alpha Cronbach 0,881 dengan kategori sangat tinggi. Penelitian ini dilakukan pada dua
kelas di SMA. Hasil penelitian menunjukkan adanya penurunan konsep alternatif yang dimiliki siswa
antara sebelum dan sesudah pembelajaran, di mana hasil penelitian konsep alternatif siswa pada kelas
eksperimen dan kelas kontrol menunjukkan ada perbedaan. Hasil reduksi konsep alternatif siswa ditunjukkan oleh beda skor pretes dan postes siswa, di mana skor postes siswa lebih tinggi dari pada postes.
其他摘要：This study aimed to reduce the alternative concepts of students with EPCOER learning
models and POE learning models on thermochemical material. This study used a test instrument in the
form of three tier tests having 98% content validity. Cronbach Alpha reliability coefficient of 0.881 with
a very high category. The research was conducted in two research classes at high school. The results
showed a decrease in the alternative concepts that students had before learning. There were differences in the alternative concepts of students in the experimental and control classes, which students in
experimental class had fewer alternative concepts compared to the student in the control class. The
reduction in the alternative concepts of students were showed by the difference of students pretest
and posttest scores.
