Application of Group Resume Learning with Contextual Approach on Mathematical Problem Solving

Abstract

Tujuan diadakannya penelitian ini untuk meningkatkan kemampuan pemecahan masalah matematis siswa menggunakan model pembelajaran group resume dengan pendekatan kontekstual. Penelitian ini dilakukan di kelas VIII salah satu sekolah di Cianjur. Metode penelitian yang dipilih yaitu kuasi eksperimen dengan design penelitian yaitu nonequivalent control group design. Instrumen yang digunakan yaitu instrumen tes kemampuan pemecahan masalah, lembar observsi dan lembar angket sikap siswa. Hasil penelitian diperoleh bahwa: Keterlaksanaan proses pembelajaran guru dan siswa menggunakan model pembelajaran group resume dengan pendekatan kontekstual berada pada kategori baik sekali; peningkatan kemampuan pemcahan masalah matematis siswa yang menggunakan model pembelajaran group resume dengan pendekatan kontekstual lebih baik secara signifikan daripada siswa yang menggunakan model pembelajaran konvensional; besar pengaruh model pembelajaran group resume dengan pendekatan kontekstual berada pada kategori sedang dengan persentase 73%; serta kebanyakan siswa memberikan sikap positif terhadap pembelajaran matematika menggunakan model pembelajaran group resume dengan pendekatan kontekstual.The purpose of this research was to improve students' mathematical problem solving abilities using the group resume learning model with a contextual approach. This research was conducted in class VIII one of the schools in Cianjur. The research method chosen was quasi-experimental with a nonequivalent control group design. The instruments used were problem solving ability test instruments, observation sheets and student attitude questionnaire sheets. The results of the study showed that: The implementation of the teacher and student learning process using the group resume learning model with a contextual approach was in the very good category; increasing the mathematical problem solving abilities of students who use the group resume learning model with a contextual approach is significantly better than students who use conventional learning models; the influence of the group resume learning model with a contextual approach is in the moderate category with a percentage of 73%; and most students give a positive attitude towards learning mathematics using the group resume learning model with a contextual approach.
