This study aims to determine the effect of the use of the OSCAR model-based Mind Mapping method on students' mathematical problem-solving skills. The subject of this study is class VIII D students consisting of 25 students. This experimental research with a quantitative approach uses a Pre-Experimental Research Design Type One Group Pretest/Posttest Design. The instruments used were Pretest/Posttest questions, student activity observation sheets, and student response questionnaires. The data from the research were processed by t-test and percentage technique. The results of the study showed that: 1) the use of the OSCAR model-based Mind Mapping method had a positive and significant effect on students' mathematical problem-solving skills. This can be seen from the results of the t-test obtained, table= 2.064 < tcalcul= 14.58 then, H-0. rejected and, H-1. Accepted, 2) Dominant student activities in the activity "Discussing with groups and actively participating in working on the given questions" with a percentage of 21.1%. 3) Students' response to mathematics learning using the OSCAR model-based Mind Mapping method is positive. This is based on the analysis of student responses, the total percentage is 80.75%, so it is included in the criteria for being very positive. It can be concluded that many students respond well to the use of the OSCAR model-based Mind Mapping method.
