The cause of the lack of mathematical problemsolving ability of students in grade VIII.1 SMPN 16 Solok Selatan was because the learning model was still concentrated on the teacher. One effort that can be done to overcome this problem was to apply the PBL model. The objective of the study was to describe the process of improving students' mathematical problem-solving skills through learning with PBL model. The type of research was classroom action research. The study consisted of two cycles consisting of five meetings for each. The last meeting of each cycle was filled with the final test. This research consisted of four components, namely: action plan; action implementation; observation; and evaluation of the action (reflecting). The research was conducted on the students of class VIII.1 SMPN 16 Solok Selatan in the even semester of the academic year 2013/2014. Research subject amounted to 20 students. The collected data were analyzed descriptively. The result of this research indicated that there was an increase in problem-solving skills of mathematics students using the PBL model. The increase was seen from the increase of the average value of the final test cycle that examined the problem-solving and the percentage of mastery of student learning outcomes. It can be concluded that the PBL model can improve the problem-solving ability of students of grade VIII.1 SMPN 16 Solok Selatan in the even semester of the academic year 2013/2014.

It was concluded that improving the mathematical problem solving ability through the PBL model is better than traditional learning.
Analysis of Mathematical Problem-Solving Abilities Taught Using Problem-Based Learning
American Journal of Educational Research
This study aims to analyze: (1) The level of students' mathematical problem-solving ability, (2) Mistakes made by students in solving mathematical problem-solving problems. This type of research is qualitative research. The subjects of this study were students of class VII-A at Tunas Baru Jin Seung Middle School, Batam City. The results showed that: (1) High-ability students were able to carry out the stages of understanding the problem, devise a plan, carry out a plan and look back. Moderate-ability students are being able to carry out the stages of understanding the problem, devising a plan, and carry out a plan. While low-ability students can carry out the stage of understanding the problem. (2) Students can understand the problem by writing down what is known and asked, but unable to explain in their sentences. Students are not able to devise a plan because of the inability to associate information with one another. Students are not able to carry out a plan, this is due to the inability of students to make plans so they do not understand how to solve problems and calculation errors occur in the completion process. Students are not able to look back obtained and give their arguments.

Based on a preliminary study at SDN Karangsono 1 that students had difficulty to solve problem-solving questions or questions presented in the form of stories, especially geometric material. The purpose of this study was to determine the ability to solve mathematical problems with the PBL model with the RME approach better than the PBL learning model. This study used a quantitative design with an experimental class and a control class. Data collection techniques used are tests and non-tes. The data analysis technique in this research is prerequisite test and hypothesis test. The results of this study were that the average mathematical solving ability of students using the PBL model with the RME approach is better than using the PBL model alone. This can be proved from the experimental class, the average indicator 1 during the pretest is 70 and when the posttest becomes 77, in indicator 2 during the pretest the average is 60 and becomes 73 during the posttest, in indicator 3 during the pretest the average is 50 and becomes 80 during the posttest, on the other hand in indicator 4 during the pretest the average is 53 and becomes 73 during the posttest. Meanwhile, in the control class in indicator 1 the average pretest was 50 and it became 65 during the posttest, in indicator 2 the average during the pretest was 60 and it became 70 during the posttest, in indicator 3 the average was 50 and it became 60 when posttest, and on indicator 4 the average is 55 to 60 during the posttest.
