This research aims to identify class XI MIPA1 senior high school students, who experience misconceptions on the kinetic theory of gas. The method used to determine students who experience misconceptions is the Certainty Response Index (IRK) method. This method has four indexes in identifying students' mastery of concepts, namely lucky guess (LG), not knowing concept (NKC/TTK), knowing concept (KC/TK), and misconception (M). The subjects of the study were senior high school students in class XI MIPA1 in Tasik Malaya. The research instrument used was a kinetic theory of gas test equipped with an IRK scale assessment instrument. This research is a quantitative descriptive research that can determine weaknesses in understanding students' physics concepts with the IRK method. The results of data analysis using IRK revealed that students who experienced lucky guess (LG) were 9.0%, students who knew the concept (TK) were 35.2%, students who lacked knowledge or did not know the concept (TTK) were 21.9%, and students experiencing misconceptions (M) of 33.8%. Based on the sub-topic analysis, the level of misconception the results are also in the high category. Thus it was concluded that through the IRK method it was identified that most students were still experiencing misconceptions, did not know the concepts, and were lucky guessed in understanding the kinetic theory of gas in the class XI MIPA1 of senior high school in Tasik Malaya.

The physics learning process at school does not involve students directly which causes the low cognitive learning outcomes of students. For this reason, it is necessary to apply an effective learning model for improving student learning outcomes. One suitable learning model is the treffinger learning model. The treffinger model provides learning activities with three stages namely basic tools, practice with the process, and working with real problems. These three stages can make students actively and creatively involved in the learning process. The purpose of this research is to find out the effectiveness of increasing cognitive learning outcomes of students on optical material by applying the Treffinger learning model. This type of research is a quasi-experimental design with a non-equivalent control group design. The research sample was taken two classes randomly as the experimental class and the control class from the student population in class XI IPA of SMA Negeri 9 Pekanbaru. The data collection instrument used students' cognitive learning achievement test consisting of pretest and posttest given to the experimental class and the control class. Data were analyzed using descriptive and inferential analysis. Descriptive analysis results obtained an average absorption capacity of 72.64% experimental class with a good learning category and 63.47% control class with quite a good category. With the results of the inferential analysis with an independent-sample t-test, there are significant differences in learning outcomes between the experimental class and the control class, where the experimental class has a higher increase in learning outcomes. Thus the use of the treffinger model is effective in improving student learning outcomes in class XI IPA of SMA Negeri 9 Pekanbaru on optical material.
