PERBANDINGAN KEMAMPUAN REPRESENTASI MATEMATIS SISWA DALAM PEMBELAJARAN KOOPERATIF TIPE NHT DAN TPS

Abstract

This quasi-experimental research aimed to compare the increasing of mathematical representation skill of students who learned in cooperative learning model of NHT and TPS type. This research design was pretest-posttest control group design. The population of this research was all students of grade 7^th of SMPN 25 Bandarlampung in academic years of 2014/2015. The samples of this research were taken by purposive sampling technique. The research data were obtained by the test of mathematical representation skill. Based on hypothesis test, it was gotten the conclusion that cooperative learning model of TPS type was better than NHT to increase mathematical representation skill.
