This research aims to describe the mathematical problem solving skills of junior high school students in relationship materials and functions with Polya strategy. The method used in research is a qualitative descriptive method. This research was conducted at SMP Negeri 35 Palembang with a class XI.6 research sample of 30 people. The research subjects were taken by 6 students, who were grouped into three categories, namely high, medium and low who were taken 2 people each from each category.. The data collection techniques in this study are tests, interviews and documentation. The results of the data obtained are then analyzed using data reduction analysis techniques, data presentation and verification. So the results of the study show that: 1) students who have high category problem solving skills are able to carry out all stages of problem solving, 2) students who have problem solving skills category are able to carry out the problem solving stages of the problem, but at the stage of carrying out planning and problem solving students make mistakes in operation and are not able to perform the stage of planning the answer correctly, 3) students who have low category problem solving skills are only able to carry out one stage that is understanding the problem and not being able to carry out the stage of planning the solving strategy planning and troubleshooting and re-examining the answers obtained correctly.

Problem Solving Skills

Learning problem-solving skills emphasizes reasoning abilities to determine conclusions based on-premises, determining alternative solutions in decision making, thinking creatively in building alternatives to get keys, and critical thinking to evaluate the best solutions in answering problems. This study aims to identify biased publications using the trim and fill method in determining the effectiveness of learning on the problem-solving abilities of junior high school students. This research is a quantitative study with a meta-analysis approach. Data collection based on quantifiable variable numerical information analysis results from mathematical problem-solving abilities in two different learning groups. The data analysis technique uses bias publication analysis with the trim and fills method with the analysis procedure of calculating the effect size, heterogeneity test, calculating the summary effect using the random-effect model, and forest-plot analysis and biased publication analysis. The results showed no publication bias. The validity of differences in innovative and conventional learning effectiveness was valid on junior high school students' mathematics problem-solving skills. This shows that innovative learning effectively improves the mathematical problem-solving ability of junior high school students.

This study aimed to examine comprehensively the effect of the application of REACT learning models based on the Malay cultural context of Riau on students’ mathematical problem-solving abilities. The research was a quasi-experimental research with Pretest-post-test control group design. The sample of this study was all students of class VII SMP 12 Pekanbaru. The results of data analysis were: (1) There was a difference of the mathematical problem-solving ability of Pekanbaru junior high school students between who learned to use REACT learning models based on the Malay cultural context of Riau and students who studied with conventional learning; (2) There was a difference of the mathematical problem-solving ability of Pekanbaru junior high school students between who learned to use REACT learning models based on the Malay cultural context of Riau and students who studied with conventional learning in terms of aspects of student ability levels, (3) There was no interaction between the learning model and the level of students’ ability to the ability to solve mathematical problems; (4) There was a difference in the mathematical problem-solving ability of Pekanbaru junior high school students who learned to use the REACT learning model based on the Malay Malay cultural context in terms of aspects of student ability levels.
