PEMBELAJARAN KOOPERATIF CO-OP CO-OP DENGAN PENDEKATAN OPEN-ENDED UNTUK MENINGKATKAN KEMAMPUAN PEMECAHAN MASALAH MATEMATIS SISWA SMA

Abstract

This research was aimed to determine: (1) whether the improvement of mathematical problem solving skills of students who get cooperative learning type Coop coop with Open-Ended approach is better than the students who get learning with Open-Ended approach; (2) how students attitude toward cooperative learning type Coop coop with Open-Ended approach. The subjects of this research were X grade students in a SMAN of Cimahi which is divided into two groups namely the experimental and control group. This research was a quasi-experimental study with a pretest-posttest non-equivalent group design. The instruments used are problem solving test, attitude scale and observation sheet of teacher and student activity. Quantitative analysis was performed using average difference test. The result of the research shows that the improvement of mathematical problem solving ability of students who get cooperative learning type Coop coop with Open-Ended approach is better than the students who get learning with Open-Ended approach. In addition, students generally show a positive attitude toward cooperative learning type Coop coop with an Open-Ended approach.
