This research was motivated by the low level of students' mathematical problem solving skills and the lack of teaching materials that were based on contextual problems or suited to students' daily lives. From this problem, the researcher aims to produce contextual problem-based teaching materials on three-variable linear equation systems to improve phase E students' mathematical problem solving skills that meet the criteria of valid, practical and effective.
This research is research with a development type, research using the 4D type. In the define stage, initial-finish analysis, student analysis, concept analysis, task analysis and learning objectives are carried out. The initial final analysis begins by analyzing the type of curriculum used in the research school, namely the independent curriculum. The problems encountered are the low level of students' mathematical problem solving skills and the lack of availability of contextual problem-based teaching materials and the teaching materials do not yet contain indicators of mathematical problem solving skills. Concept analysis, namely that there are 4 concepts compiled, namely the definition of SPLTV, solving SPLTV using the elimination method, solving SPLTV using the substitution method, and solving SPLTV using the combined method. The results of this concept analysis are to plan the tasks that will be given to students. The define stage ends with an analysis of learning objectives obtained from the results of concept analysis and task analysis.
The design stage is carried out by compiling teaching material instruments which aim to assess the validity of teaching materials. Preparing student response questionnaires to assess the practicality of teaching materials, and compiling mathematical problem solving skills test questions to assess the effectiveness of teaching materials.
The development stage is the stage of developing teaching materials, teaching materials are developed according to the initial design, product validation, product revision, and product testing. Teaching materials are said to meet valid criteria with an interval of 70.01% - 85%. Teaching materials are said to be practical if they meet the interval 70.01% - 85.00%. Teaching materials are said to be effective if the Asimp.sig value results. (2-talled) < 0.05, with the conclusion that the use of contextual problem-based teaching materials has an effect on students' KPMM.
The results of data analysis on the validity of teaching materials obtained an average score from all validators of 92.34% with very valid criteria. The practicality results of teaching materials in limited class trials were 81.69% with practical criteria. The results of the practicality of teaching materials in field trials were 79.22% with practical criteria. Thus, the teaching materials have met the criteria for validity and practicality.
The results of data analysis of mathematical problem solving skills tests showed that the average mathematical problem solving skills of experimental class students who studied using contextual problem-based teaching materials was higher than control class students who studied without using contextual problem-based teaching materials. The average score for the mathematical problem solving skills test for the experimental class was 87.53% and the control class was 77.53%.
The result of the Asymp sig value from the Mann Withney test is 0.000 < 0.05, which means H0, which means the use of contextual problem-based teaching materials has an effect on improving students' mathematical problem solving skills. So that the teaching materials have met the effective criteria.
The dissemination stage is carried out by creating articles and publishing them in accredited journals, and distributing teaching materials to schools that contributed to this research. The result of this development research is that it has produced contextual problem-based teaching materials on three-variable linear equation systems to improve phase E students' mathematical problem solving skills that are valid, practical and effective to use.
