Peningkatan Kemampuan Pemecahan Masalah Matematis Mahasiswa melalui Model Pembelajaran Group Investigation

Abstract

The problem solving ability of students still low the problem of this research was mathematics. The purposes of this research was to know analyze improvement in mathematics problem solving ability of students that given group investigation learning with students that given direct learning. This type of research is a quasi-experimental research. The population in this study were all students of Mathematics Education Study Program UIN North Sumatra Medan and the samples were taken by cluster random sampling based on existing classes, namely PMM-4 class as an experimental class and PMM-2 as a control class. Data collection techniques in this study were using tests of students' mathematical problem solving abilities (pre tests and post tests) in the form of essay tests. The collected data is then searched for the N-gain value and analyzed using t test with SPSS 17 software.. Based of the results analysis, it showed that: Improvment of the students’ mathematics problem solving ability that given group investigation learning model was higher than the students’ mathematics problem solving abiliy that given direct learning. His then, suggested that group investigation learning model used for lectures to improved students’ mathematics problem solving ability.

“…Pembelajaran pemecahan masalah matematis sangat penting, sehingga hampir disetiap kurikulum diperlukannya kemampuan pemecahan masalah. Sependapat dengan NCTM (Siregar, 2019) hal yang utama diperlukan dalam kegiatan penemuan dan aplikasi yang harus terjalin diseluruh kurikulum matematika untuk menyediakan konteks belajar dan menerapkan ide matematika dan terdapat lima standar proses yang hendak dicapai salahsatunyayaitukemampuan pemecahan masalah matematis. Oleh sebab itu, matematika dipelajari semua tingkatan sekolah mulai dari sekolah dasar, menengah maupun perguruan tinggi agar semua dapat menguasai ilmu matematika dengan baik.…”
