Kemampuan Komunikasi dan Representasi Matematis dalam Pembelajaran Berbantuan Lembar Kerja Siswa Berbasis Teori Bruner

Abstract

This study aims to determine differences in improvement of communication capabilities and representation of students, student activities and student responses before and after assisted learning theory based LKS Bruner. The study was conducted on 33 students of class VIII SMP Negeri 1 Semitau Kapuas Hulu in West Kalimantan. The method used was experimental research design is one group pretest-Posttest. The results of data analysis showed that the difference in a significant improvement between pretest and posttest, namely mathematical communication (pretest: 47.3%; posttest: 67.87%) and the mathematical representation (pretest: 50.9%; posttest: 67.39% ). This suggests that learning to use the worksheets based on the material theory Bruner Expression Algebra factorization can improve communication skills and mathematical representation of students. Activity of students during the learning is high, especially at the stage of enaktif and students' response to LKS-based assisted learning theory Bruner is high
