This study is a quasi-experimental study that aims to determine the effect of increasing student communication skills in discussing students' learning outcomes in basic chemistry learning. The indicators of student discussion skills include: (1) conveying messages well, (2) using clear language, (3) expressing opinions clearly, (4) listening to his friends 'opinions carefully, and (5) responding to his friends' opinions. The communication skills in the discussion were observed in each learning process that lasted for 14 meetings.
