Abstract

This research development aims to develop mathematical teaching materials with PQ4R method to instill the disposition skill of students' understanding on mathematical concepts. PQ4R is an instructional method which is done through reading activities. The activities in the learning process include: preview, question, read, reflect, recite and review. The disposition understanding of mathematical concepts is the tendency in understanding math concepts being studied, explaining the link between the concepts and applying the concepts in a flexible manner, accurate, efficient and precise in problem solving. The subject in this research were students of VIII B of JHS Daarul Ma'Arif 2015/2016 academic year with middle-upper thinking characters. The data were obtained through observation sheet and interviews. The research results showed that the instructional mathematical learning materials with PQ4R method was effective when it used clear language, provided clear explanations on the completion of the steps in the example given, less practices while the tasks should be in form of stories. Most students like these kind of mathematics teaching materials therefore they can enhance the disposition skill of students' understanding on mathematical concepts. Penelitian ini bertujuan untuk mengembangkan bahan ajar matematika dengan metode PQ4R untuk menanamkan disposisi pemahaman konsep matematis siswa. PQ4R adalah metode pembelajaran yang dilakukan dengan kegiatan membaca. Kegiatan dalam proses pembelajarannya yaitu preview, question, read, reflect, recite dan review. Disposisi pemahaman konsep matematis adalah kecendrungan seseorang bersikap dalam memahami konsep matematika yang sedang dipelajari, menjelaskan keterkaitan antar konsep dan mengaplikasikan konsep secara luwes, akurat, efisien dan tepat dalam pemecahan masalah. Subjek penelitian ini adalah siswa kelas VIII B SMP Daarul Maarif tahun pelajaran 2015/2016 yang memiliki karakter berpikir menengah ke bawah. Data penelitian diperoleh melalui lembar observasi, dan wawancara.
