Abstract

The purpose of this study was to find out: 1) How did the motivation to learn Mathematics increase after applying the scientific learning model to class VIII.C students of SMP Negeri 12 Mataram even semester of the 2021/2022 Academic Year; 2) How did the learning outcomes of Mathematics increase after the scientific learning model was applied to class VIII.C students of SMP Negeri 12 Mataram even semester of the 2021/2022 Academic Year. The research subjects totaled 32 students consisting of 17 male students and 15 female students. The subjects that were the target of the research were Mathematics. Based on the results of the achievement of action research indicators in class VIII.C of SMP Negeri 12 Mataram which were carried out in three cycles, it can be concluded that the learning outcomes of class VIII.C students of SMP Negeri 12 Mataram for the academic year 2021/2022, with a scientific learning model can be improved with the final results research is the class average before the action 67.94 or 53.13% classical completeness, to 72.63 or 65.63% classical completeness in cycle I, increased to an average of 74.69 or 81.25% in cycle II and experienced an increase to an average test of 76.94 or 90.63% in cycle III. From the results of student observations it was shown that there was an increase in student motivation which in cycle I obtained a score of 2.93 or Less to 3.33 or Enough in cycle II and 3.92 or Good in cycle III. The increase in student activity in learning mathematics is supported by the increase in teacher activity in maintaining and improving the learning atmosphere using the scientific learning model, this can be seen from the observations of teacher activities where in cycle I a score of 22 or 61.10% was obtained, becoming 26 or 72, 23% in cycle II and increased to 33 or 86.12% in cycle III.

Abstract

The purpose of this study was to find out the application of the Realistic Mathematics Education (RME) approach to improve the Mathematical Creative Thinking Skills of Class IX.E Students of SMP Negeri 12 Mataram Odd Semester 2022/2023 Academic Year. The research subjects were all 32 students in class IX.E at SMP Negeri 12 Mataram for the academic year 2022/2023 consisting of 15 boys and 17 girls. The results showed that: 1) In this study the teacher's activity in managing learning was measurable and it could be seen that the teacher was able to manage learning activities well. Teacher activities in managing learning using the Realistic Mathematics Education (RME) approach between cycle I, cycle II and cycle III experienced an increase, namely with a percentage value of 61.33% (good enough) in cycle I and increased in cycle II to 74.28%. (good) in the third cycle increased with a percentage of 88.88% (very good); 2) Student activity in participating in the learning process is measurable and it can be seen that students are active and in control. Student activities in participating in learning using the Realistic Mathematics Education (RME) approach between cycle I, cycle II and cycle III experienced an increase, namely with a percentage value of 65.33% (enough) in cycle I and increased in cycle II to 78.57% ( good) in the third cycle it increased with a percentage of 85.33% (very good); 3) Student learning outcomes through the application of the Realistic Mathematics Education (RME) approach can improve student learning outcomes in Mathematics learning for Class IX.E SMP Negeri 12 Mataram. This can be seen clearly from the test data on student learning outcomes through the Realistic Mathematics Education (RME) approach. The pre-action quiz questions obtained 34.38% and the first cycle was 59.36%, the percentage value of students was included in the (good enough) category, while the RPP quiz questions cycle II reached 78.13% including the (good) category, and then in the lesson plan quiz questions for cycle III it reached 87.50% more than cycles I and II and the percentage of students was included in the (very good) category.
