Meningkatkan Kemampuan Penalaran dan Komunikasi Matematika Melalui Model Pembelajaran Kooperatif Tipe Jigsaw di SMKN 1 Mananggu

Abstract

s This study aims to determine the increase in students' mathematical reasoning and communication skills through the Jigsaw cooperative learning model. The type of research used is classroom action research with the research subject being class XI students of SMK Negeri 1 Mananggu, Boalemo Regency in the 2019/2020 school year. The number of students was 30 consisting of 16 boys and 14 girls with average mathematical reasoning abilities of 54.8% to 63% and 33.34% to 73.34% mathematical communication skills. This research was conducted in 2 cycles. The results of this study indicate that the use of this model can improve students' mathematical reasoning and communication skills on flat shape material. The results of the analysis show that in the first cycle, only 19 of the 30 students achieved 63.33% mastery of mathematical reasoning, and the other 20 students only achieved 66.67% of their mathematics communication skills. In the second cycle, the students' mathematical reasoning abilities tended to increase to 20%, that is, 25 students completed 83.33% of their learning. Meanwhile, the students' mathematical communication skills also increased to 20%, with the result that the number of students who completed their studies became 26 students or 86.67%.
