Mathematics learning does not only focus on students' mastery of numbers, but also functions significantly in developing the ability to solve problems holistically. This skill is not something that is taught separately, but is integrated into the entire educational process, offering a real context so that mathematical concepts and abilities can be understood and applied. One approach that is highly recommended to achieve this is Problem Based Learning (PBL). This method has been proven effective in improving students' critical thinking skills through exploration and solving relevant problems, allowing students' knowledge to grow in a constructive way. The low achievement in problem-solving competency in Indonesia is a strong reason to apply PBL in mathematics teaching. This study aims to analyze the literature on the application of PBL to improve students' problem-solving abilities. Data were collected and analyzed from relevant journals, and testing and comparison of results were carried out to identify patterns and results from previous studies. In addition, this study also applies a bibliometric approach to explore publication trends, keywords, and the development of themes related to PBL in mathematics education. The analysis was carried out using VOSviewer software to map the relationship between topics and the progress of PBL research themes in the world of mathematics education.

Abstract. This study aims to determine whether there is an influence of the problem based learning model integrated with video animation on the mathematical problem solving abilities of class VIII students. This research was conducted at SMP Negeri 6 Percut Sei Tuan, TA 2022/2023. The research method used is a quasi-experimental design method. The sample in this study consisted of two classes namelyclass VIII-3 as the experimental class and class VIII-4 as the control class. The experimental class uses a problem-based learning model integrated with video animation and a control class with conventional learning. Obtaining the average score of the final test (posttest) of the experimental class students is equal to 89.22, whereas in the control class the average result of the student's final test score was 72.55, in the hypothesis test, the results obtained from the average difference test (t-test) with statistical values t_hitung>t_tabel(10.56 > 1,671 ) which means there is an influence from the usea problem-based learning model integrated with video animation that is applied to the experimental class. This indicates that the mathematical problem solving abilities of the experimental class students are better than the control class.
