Improving Students' Mathematical Communication Abilities and Self-Confidence through The Snowball Throwing Learning Model

The purpose of this study is to find out whether the snowball throwing learning model can improve students' mathematical communication skills and self-confidence. This research was conducted in SMP Negeri 2 Cikalongkulon. The research method used was quasi-experimental with nonequivalent control group design. For the experimental class, the treatment was given using the snowball throwing learning model while the control class was given scientific learning. The population in this study were all students of class VII, with a sample of two classes namely class VII C as the experimental class and class VII E as the control class and selected based on the purposive sampling technique. Based on the tests of mathematical communication skills that have been obtained that the improvement of students 'mathematical communication skills using the snowball throwing learning model is better than students who use scientific learning, and based on the self-confidence questionnaire given in the experimental class and control class, it is found that students' self-confidence using the snowball throwing learning model better than students who use scientific learning.
