Abstract

Heat is a material that is close to everyday life. However, most students still have misconceptions about this material. Thus, teachers need to develop teaching materials that can reduce the misconception of heat material. One alternative is to use teaching materials with cognitive conflict strategies. The research aims to develop teaching materials that are able to reduce students' misconceptions about heat material. The development model used is the 4D model which consists of four stages, namely defining, designing, developing, and distributing. The teaching materials developed include lesson plans, textbooks, student worksheets, and tests. The subjects of the study were seventh-grade students in Lamongan regency which consisted of 10 state junior high schools and private junior high schools. The research instrument was a feasibility test sheet for teaching materials and a questionnaire to see students’ responses. Data collection techniques used the feasibility sheet of teaching materials and questionnaires. Therefore, the result shows that cognitive conflict-based teaching materials are appropriate to be used classroom with a score between 3.0 and 3.9 and a reliability coefficient value of more than 90%.  and can reduce misconceptions with a percentage reduction in misunderstandings from 10 junior high schools in the Lamongan regency ranging from 30.3 to 47.8 percent.

Abstract

Untuk menangani berbagai masalah matematika, kemampuan dalam memahami konsep sangat penting dalam mempelajari ilmu matematika. Teknik pemilihan subjek yang digunakan oleh peneliti yaitu purposive sampling. Hal ini berdasarkan hasil observasi peneliti dengan salah satu guru matematika MTS Sunan Drajat yang mengatakan bahwa kelas VII A adalah salah satu kelas yang siswanya dalam memahami konsep tergolong rendah. Tujuan dari penelitian ini yaitu untuk meningkatkan kemampuan pemahaman konsep siswa kelas VII MTS Sunan Drajat. Pendekatan yang digunakan yaitu deskriptive qualitative dengan menggunakan metode eksperimen. Kemampuan siswa dalam memahami konsep dalam bentuk deskripsi diukur melalui ujian tulis. Hasilnya menunjukkan bahwa penerapan model Problem Based Learning (PBL) berhasil meningkatkan pemahaman konsep siswa kelas VII A MTS Sunan Drajat. Hasil pretest dan posttest menunjukkan gain sebesar 0.53, yang menunjukkan bahwa siswa dalam kategori peningkatan sedang.
