NURUL IZATUL AZIZAH, NIM. 2110246783, Development of Approach-Based Electronic Teaching Materials Contextual Teaching and Learning (CTL) on Systems of Linear Equations and Inequalities Phase E to Improve Mathematical Problem Solving Skills, supervised by Dra Yenita Roza, Ph.D and Dr Kartini, M.Si.
This research was motivated by the low level of students' mathematical problem solving skills and the limited teaching materials that could improve mathematical problem solving skills. In connection with this, this research aims to produce approach-based electronic teaching materials Contextual Teaching and Learning (CTL) on systems of linear equations and inequalities to improve mathematical problem solving skills that are valid, practical and effective to use.
This type of research is development research or research and development. The development model used is a 4D model, namely define (definition), design (planning), develop (development), and desseminate (Distribution). At the level of define things that are done, namely start-finish analysis, student analysis, competency analysis. In the initial final analysis, the results obtained were that the applicable curriculum was an independent curriculum, the problems faced were the low level of students' mathematical problem solving skills, and the lack of availability of teaching materials that improve mathematical problem solving skills. Researchers also analyze students about the problems students face in learning mathematics. Stage define ends with a specification of learning objectives.
Level design (defining) researchers do this by compiling test instruments used to assess the validity, practicality and effectiveness of teaching materials. Choosing media that suits the way students learn so that researchers choose to use audio-visual media in the form of video. Develop a systematic teaching material by determining the components of the teaching material, and making an initial design of the teaching material being developed.
Level develop includes developing teaching materials according to the initial design, product validation, product revision, and product testing. Teaching materials are said to be valid if the minimum level of validity achieved based on the validator's assessment results is in the valid category with a scale of 70.01% − 85%. Teaching materials are said to be practical if the percentage of practicality level is more than 70%. Meanwhile, teaching materials are said to be effective if the experimental class learning results are better than the control class learning results.
Based on the results of validity data analysis, the validity of teaching materials is 89% in the very valid category, the validity of mathematical problem solving skills questions is 91.7% in the very valid category. The results of the trial of the mathematical problem solving skills test showed that the correlation coefficient for the validity of items number 1, 2 and 4 had a very good interpretation, and item number 3 had a good interpretation. The test reliability correlation coefficient value is very high with excellent interpretation quality. The discriminating power index test results obtained for item number 1 were 0.60 (good), item number 2 was 0.73 (very good), item number 3 was 0.30 (fair), and item number 4 had a discriminating power index of 0.35 ( Enough). The results of the test on the level of difficulty of the questions showed that test questions number 1 and 2 were at a medium level of difficulty and questions number 3 and 4 were at a difficult level of difficulty. Based on the results of the data analysis that has been carried out, it can be concluded that the teaching materials and tests of mathematical problem solving skills are valid and can be used as research instruments.
The practicality results of teaching materials in limited trials were 90.28% in the very practical category. The practicality results of teaching materials in field trials were 90.35% for student response results, teacher response results with an average of 94.14% and teacher observation results with an average of 90.6%. Thus, it can be concluded that the teaching materials developed are practical.
Based on the results of data analysis tests on mathematical problem solving skills, it was found that the average mathematical problem solving skills of students who used experimental class teaching materials were higher than control class students who did not use teaching materials. The results of the N-Gain test showed that students who used CTL approach-based teaching materials had a higher increase in mathematical problem solving skills than students who did not use teaching materials. Because of the average score posttest experimental class higher than average score posttest control class, and the increase in mathematical problem solving skills of experimental class students is higher than the increase in mathematical problem solving skills in the control class, so it can be concluded that teaching materials based on the CTL approach have proven to be effective.
Level disseminate This is done by creating articles for publication, and distributing teaching materials to schools that contributed to this research. This development research has produced approach-based electronic teaching materials Contextual Teaching and Learning (CTL) in Phase E Systems of Linear Equations and Inequalities Material to improve mathematical problem solving skills that are valid, practical and effective to use.

Keywords: Teaching materials, Approach Contextual Teaching and Learning(CTL), Mathematical Problem Solving Skills.
