Abstract

Problem solving is one of the essential abilities every individual must have. Problem solving is a life skill that involves analyzing, interpreting, reasoning, predicting, evaluating and reflecting. This study aims: 1) To determine whether there are differences in the initial ability of the experimental and control classes. 2) To find out whether improving students' mathematical problem solving skills after using realistic mathematical learning models with the help of teaching aids is better than classes given conventional learning. 3) To determine whether the increase in student interest in learning after using a realistic mathematical learning model with the help of teaching aids is better than the class given conventional learning. This type of research is quantitative exponent research, which aims to determine the improvement of mathematical problem solving abilities and learning interests of junior high school students through realistic mathematics learning with the help of teaching aids. The population of this study is all grade VII students of PGRI Walantaka Junior High School in the odd semester of the 2023/2024 academic year. The sample of this study was 28 students VII A as an experimental class and 24 students in class VII B as a control class, so the sample in this study was 52 students. From the calculation results,  the N-Gain Value Test Pretest and Posttest results  in the experimental class had an average of 58.83 while the control class had an average of 10.38.  Test Hypothesis The statistical value of the Z test is calculated to be –6.060 and the probability is 0.000. Thus H0 is rejected. So it is concluded that: (1) There is no difference in the initial ability of experimental class students and control class. (2) The ability to solve mathematical problems on fractional material using Realistic Mathematical Learning Models with the help of Teaching Aids is better than the Mathematical Problem Solving Ability using conventional Learning Models. (3) Student learning interest in fractional material using Realistic Mathematics Learning Model with the help of Teaching Aids is better than student learning interest using conventional Learning Model
