Mathematical Problem Solving Ability of Junior High School Students through Ang’s Framework for Mathematical Modelling Instruction

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.

One of the cognitive skills that students must have is problem-solving ability. Therefore, a standardized test is needed to measure this ability. However, until now, the tests used to measure mathematical problem-solving ability were not standardized. This research aims to develop a valid and practical mathematical problem-solving test in the discussion of triangles and rectangles. This research is part of the R&D 4D type with steps: Defined (analysis to develop a test), Design (designing a problem-solving test form), and Develop (expert judgment and small group trials). The instrument in this research was the validation sheet used by the validator to assess each test item. The data analysis technique used the Aiken method for expert judgment and qualitative descriptive for development testing. The result is a valid and practical mathematical problem-solving test because the V-Aiken value is more than 0.532. Based on this, the instrument can be used to measure the mathematical problem-solving ability of junior high school students in the discussion of triangles and rectangles.

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.

Self Confidence

This research was conducted to analyze the relationship between self confidence with the ability of mathematical problem solving of IX grade junior high school students. Research method is correlation analysis. The subject of this study consisted of 35 students of student in grade IX junior high school in Cimahi. Sampling technique using random technique. The test were done by giving about problem solving skills in the form of essay 5 items and self confidence questionnaire with Likert scale. The data analysis steps used were normality, correlation test, determine the coefficient of determination or coefficient determinant to see contribution or influence of variable self confidence to variable the ability of mathematical problem solving and continued with significance test (t test). Based on the result of research, it can be conclude that there is a significant relationship between self confidence in the ability of solving mathematical problems of junior high school students.Keywords: the ability of mathematical problem solving, self confidence, junior high school students.
