UPAYA MENINGKATKAN AKTIVITAS DAN HASIL BELAJAR MATEMATIKA MATERI GARIS SINGGUNG LINGKARAN MELALUI MODEL PEMBELAJARAN KOOPERATIF TIPE JIGSAW PADA SISWA KELAS VIII D SMP NEGERI 2 WARUREJA TAHUN PELAJARAN 2017/2018

Abstract

This research aims to determine: (1) improvement in mathematics learning activities through the application of the jigsaw type cooperative learning model, (2) increase in mathematics learning outcomes through the application of jigsaw type cooperative learning models, (3) how much tangent material increases the mathematics learning activities and results circle on class VIII D SMP Negeri 2 Warureja semester 2 of the school year 2017/2018 with the implementation of the jigsaw type cooperative learning model. The research was conducted in 2 cycles, with the research population being students of class VIII D SMP Negeri 2 Warureja in the year 2017/2018, which numbered 34 children with the number of each cycle carried out with 4 (four) stages namely; action planning, implementation of action, observation, and reflection. The conclusions from the results of classroom action research are: (1) through the application of concrete jigsaw cooperative learning models can increase mathematics learning activities by 8.24%, ie from cycle 1 by 62.94% with fairly active criteria to 71.18% at cycle 2 with active criteria, (2) the application of the jigsaw type cooperative learning model can improve student learning outcomes in mathematics learning by 10.59%, that is in the first cycle of 65.29% increased to 75.88% in cycle 2.
