Abstract

This research was aimed to describe the effects of problem-solving models to improve Communicating Skills and mastery of students’ Chemistry concepts. This research using a quasi-experimental method with Non-Equivalence Pretest-Posttest Control Group Design. The sample was obtained by cluster random sampling technique. Effectiveness is evidenced by the improvement of communicating skills and mastery of students’ Chemistry concepts which is supported by a test of influence. The results of the study obtained that communicating skills and mastery of students' Chemistry concepts was high and have a large measure of influence with problem-solving models. The average value of n-Gain skills in communicating and mastering students' concepts in the experimental class is 0.71 with high criteria and the control class is 0.30 with low criteria. The average result of the experimental class size effect calculation for the experimental class is 0.94 with large criteria and the control class is 0.70 with moderate criteria. The conclusions of this study were problem-solving model have a great influence in improving communicating skills and mastery of students' Chemistry concepts.
