Can Co-op Type Cooperative Learning Improve Students' Mathematical Generalization Ability?

Abstract

The purpose of this study is an effort to improve mathematical generalization abilities and student learning outcomes in the material of arithmetic sequences and series using the cooperative learning model of the Co-op Co-op type of class X accounting students at Teratai Putih Global 2 Bekasi Vocational School. Academic year 2022/2023. The research method is classroom action research using the co-op co-op cooperative method. This research includes 3 cycles where each cycle includes 4 stages namely planning (planning), acting (implementation), observing (observation), reflecting (reflection). The time of this research was 2 months from August 2022 to September 2022 with 14 research subjects, while data was collected through tests, interviews and observation. The results of the research showed that there was an increase in mathematics learning outcomes in class X students. This was evidenced by the average results of the mathematics test in each cycle increased, namely in cycle 1 = 60.714, cycle 2 = 66.428, and cycle 3 = 72.857. The results of the interviews conducted concluded that learning mathematics on arithmetic sequences and series using the cooperative co-op co-op method is fun for students. This study concludes that learning mathematics using the cooperative co-op co-op method can improve students' mathematical generalization abilities and mathematics learning outcomes.
