Rebuttal is an essential aspect in scientific argumentation skill. Level of scientific argumentation skill depends on the quality of the rebuttal process. Students who can produce a high-quality rebuttal to defend their claims are proved higher level of scientific argumentation skill than the student who can only produce claims, evidence and reasoning. Problem-based learning (PBL) is a learning model that provides real life ill-structured problem, that need to be solved through investigation and discussion. It is able to help students to enhance their rebuttal skill. This research was aimed to analyze the rebuttal improvement process by applying PBL based module in 10th-grade student of SMAN 1 Punung. This research was an evaluation stage from our R&D research using pretest-post test control-experiment group design. Data were collected using test, interview, and classroom observation. The result showed that the students rebuttals in the experimental group increase up to 27,27%. The t-test result also indicated different significant result between pretest and posttest scores. Based on the research result can be concluded, that by implementing PBL based model in the10th-grade senior high school is able to improve students rebuttal skill.
