Abstract

This study aims to determine the effectiveness of the Project Based Learning (PjBL) learning model through the educational game media snakes and ladders on students' mathematical problem-solving abilities. The background of this national research is based on the low mathematical problem-solving abilities of students as shown by international data, as well as the still dominant use of conventional learning methods that do not actively involve students. This study uses a quantitative approach with a quasi-experimental method and a Nonequivalent Pretest-Posttest Control Group Design. The subjects of the study were grade VIII students at SMP Negeri 7 Kuningan in the 2024/2025 academic year, with samples consisting of two classes: an experimental class using the PjBL model through educational games, and a control class using conventional learning. Data were collected through pretest and posttest tests and student response questionnaires. The results showed that there was no significant difference in initial abilities between the two classes. However, after the treatment, there was a significant difference in the posttest results and an increase in the N-Gain score of mathematical problem solving ability between the experimental and control classes, which were analyzed using the Mann Whitney U non-parametric test. In addition, the results of the questionnaire showed that students gave a positive response to learning with the PjBL model through the snake and ladder educational game, with an average percentage of 75.025% in the high category. Thus, it can be concluded that the PjBL model through educational games is effective in improving students' mathematical problem solving abilities and is able to create a fun and interactive learning atmosphere.

Abstract

The 2013 curriculum includes several changes in the teaching and learning process. School conditions (principals, teachers, administrative staff, and students) have different enthusiasms, even feeling unprepared for the curriculum changes. The purpose of this study is to determine the perception of mathematics teachers regarding how the 2013 curriculum is implemented in the learning process. The data collection method used is qualitative descriptive in a natural setting, using interview methods, filling out questionnaires by respondents and documentation. Purposive sampling techniques were used in determining research subjects, The subjects in this study were mathematics teachers who taught in class IX from several schools in Kuningan Regency, consisting of MTs Negeri 3 Kuningan, SMP Negeri 7 Kuningan, and SMP Negeri 1 Kadugede. From the results of the questionnaire, the average teacher response was obtained, including resource person F, who received an average of 95%. Interviewee S with an average of 65%, and source Y with an average of 69%. The overall average of the teacher perception questionnaire was 76%, this shows that the 2013 curriculum has been implemented well and effectively to support mathematics learning. This study revealed that the implementation of the 2013 curriculum for mathematics in class IX was effective, but it was time consuming for teachers to provide the material to students, causing them to be less involved in researching the material and focusing more on interactivity
