Mathematical problem solving ability is a complex cognitive activity, as a process to fix a problem that is encountered and to complete the necessary number of strategies. Train students with problem solving in mathematics is not just expect students can solve problems or issues are given, but it is expected habits in the troubleshooting process allows him to live a life that is full complexity of the problem. Based on interviews with some seventh grade math teacher, obtained information that the students are still not familiar with the problems of solving problems and generally they are less able to write the resolution, especially concerning one variable linear equations. This study, a qualitative descriptive study.The subject of research as much as 3 wherein selecting the students backwardly random. Problem solving ability explored through interviews guided by the problem-solving abilities. Then analyzed descriptively qualitative. From the results of this study concluded that the S1 has a problem-solving ability is very high, while the S2 and S3 have an ample problem-solving abilities.

The research aims to develop teacher and student handbooks for realistic mathematics lessons for elementary schools. The development of this handbook is based on the reality in the field where the handbook of teachers and students especially the subjects using the 2013 curriculum still do not exist, and in daily learning activities teachers and students still use books that use themes. This research uses development research (Developmental Research). The subjects of this study were grade V students of SD Negeri 163085, H.A Bilal Tebingtinggi City and SD Negeri 106162, Medan Estate District, Deliserdang Regency. In the initial stage, observations were made during the learning process at the two schools and continued with interviews with students and teachers. From the results of these observations and interviews a primary school realistic mathematics teacher and student handbook was prepared. Furthermore, the realistic elementary school mathematics teacher and student handbook is validated by a team that aims to see and assess the quality of the realistic elementary school teacher and student mathematics handbook in order to arrange an effective handbook that will be used by teachers and students in learning. The validation results show that realistic mathematics teacher and student handbooks are developed in both categories and can be used in teaching and learning. The media book test was conducted on grade V students of SD Negeri 163085 Tebingtinggi city and SD Negeri 106162 Medan Estate Deliserdang Regency. The trial results show that the elementary school teacher and student mathematics handbook is effective and can help facilitate understanding of mathematical concepts at the elementary school level. This can be seen from the number of students who can reach the KKM from the two schools is increasing. For SD Negeri 163085 HA Bilal, Tebingtinggi City, if at the time of the pre-test only 1 student (3%) was able to reach the KKM, then after being given the learning process using a teacher and student handbook developed the number of students who could reach the KKM increased to 24 students (82.7%) while those under the KKM were only (17.3%) or 5 students. The same thing was seen in SD Negeri 106162, Medanestate Subdistrict, Deliserdang Regency. If at the time of the Pre-test only 2 students (6.6%) had scored above the KKM, after the post-test there was an increase in students who achieved the KKM score of 25 students (83.3%). An increase of 76.7% when compared to the pre test. Keywords: Handbook, teacher, student, PMR

This research aims: (1) to determine whether problem-based learning models improve mathematical problem-solving abilities and self-efficacy; (2) to explore the interaction between students' initial mathematical abilities and the learning model. The study employed a quasi-experimental quantitative design, with ANOVA used for inferential data analysis. Fifty eighth-grade students from SMP Negeri 3 Aek Kuo in the academic year 2022/2023 were examined. The null hypothesis (H0) was accepted, and the alternative hypothesis (Ha) was rejected since the significant F-test value was 0.178 > 0.05, and the T-test value was 0.692 > 0.05, indicating no significant difference in the average scores between experimental classes I and II. PBL students demonstrated better performance in answering mathematical problems compared to those in the direct learning group. Experimental class 1 achieved a mastery level of 84%, while experimental class 2 achieved a mastery level of 64%. PBL learners exhibited higher self-efficacy compared to those learning through direct instruction. Hypothesis testing indicated that students in experimental class 1 had stronger confidence in mathematical problem-solving compared to students in experimental class 2. The problem-based learning (PBL) methodology did not have a significant impact on students' mathematical problem-solving abilities. Hypothesis testing using interaction analysis yielded a significance value of 0.730 > 0.05. Both PBL and students' basic mathematical abilities influenced self-efficacy. Interaction analysis indicated a significance value of 0.000 < 0.05.Keywords: Problem based learning, early math skills, math solving, self efficacy
