Collaborative Learning's Effect on Mathematical Communication Skill

Abstract

This study aims to determine the increase in mathematical communication skills through Collaborative Learning. This study is an experimental study with a pre-test post-test control group design. Researchers randomly selected two groups of 30 students each from 183 Grade 8 students at a junior high school in Lembang, Indonesia. The mathematical communication skills test is used as a measuring instrument. Quantitative data analysis was performed using t-test, Mann-Whitney, and Rank-Spearman. The results showed that the increase in the mathematical communication skills of students who received Collaborative Learning was better than students who received conventional learning.
