One of the efforts to improve the quality of education in Indonesia is to make improvements and updates to the learning model. One of the obstacles that occurs in MA Al-Ma'arif Singosari is the use of learning models that are still monotonous and less varied. The RMS learning model is a constructivism learning model so that the learning process is student-centered and demands active involvement to develop students' mindsets. The purpose of this study is to describe the significant differences in problem-solving skills between groups of students who use the RMS learning model (reading, mind mapping, and sharing). This study uses a type of quantitative research using experimental methods. This study applied a nonequivalent control group design. Based on the results of data analysis carried out by researchers through independent sample t-tests, it produces Sig. (2-tailed) of 0.00. These results show 0.00 <0.05, so  is rejected and  is accepted. So it can be concluded that there is a significant influence on the RMS (Reading, Mind Mapping, and Sharing) learning model on students' ability to solve problems in class X Aqidah Akhlak subject at MA Al-Ma'arif Singosari.
