Abstract

Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan pemahaman konsep dan koneksi matematik siswa di SMP Swasta Tarbiyah Islamiyah Hamparan Perak pada materi kubus dan balok melalui pendekatan matematik realistik. Untuk mengetahui seberapa besar peningkatan yang diperoleh, siswa diberikan tes kemampuan pemahaman konsep dan koneksi matematik. Peningkatan kemampuan pertama kali dianalisis menggunakan rumus gain ternormalisasi untuk kemudian di olah menggunakan rumus ANAVA dua jalur. Rumus ANAVA dua jalur juga digunakan untuk mengetahui terdapat atau tidaknya interaksi antara model pembelajaran dan kemampuan awal matematika siswa terhadap peningkatan kemampuan pemahaman konsep dan koneksi matematik. Hasil penelitian menunjukkaan bahwa (1) peningkatan kemampuan pemahaman konsep dan koneksi matematik siswa yang diajarkan melalui pendekatan matematik realistik lebih tinggi dari pada kemampuan pemahaman konsep dan koneksi matematik siswa yang hanya di ajarkan melalui pembelajaran biasa, (2) tidak terdapat interaksi antara model pembelajaran dan kemampuan awal matematika siswa terhadap peningkatan kemampuan pemahaman konsep siswa, dan (3) tidak terdapat interaksi antara model pembelajaran dan kemampuan awal matematika siswa terhadap peningkatan kemampuan koneksi matematika siswa.

Abstract

The purpose of this research in the design of Quasi Experiment is to investigate the effect of the Realistic Mathematical Approach (PMR) on the ability to understand students' mathematical concepts, the ability of students' mathematical connections and the interaction between learning approaches with students' initial abilities on the differences in the influence of students' understanding abilities and students' mathematical connections. The research was carried out at Hikmatul Fadhillah Islamic Private Middle School in class VII with 118 students. This research is an experimental study with a test-post-test control group design research design. The population in this study were all students of class VII by taking a sample of two classes (experimental class and control class) through random sampling techniques. Data obtained through KAM test, mathematics concept comprehension ability test, and mathematics connection ability test. Data were analyzed by two-way ANAVA test. Before using the two-way ANAVA test homogeneity tests were used in the study and normality in this study was 5% significant. The results of data analysis showed that the average concept comprehension ability test was 71.43 and the control class was 62.54, with a value of sig = 0 with 0 <5 0.05, so there was a difference in the effect of students' understanding of mathematics concepts being taught with a mathematical approach realistic mathematics (PMR) with the usual learning approach, the average test ability of experimental and control mathematical connections is 70.43 and 67.76 with sig = 0, with 0 <∝ 0.05, then there are differences in the effect of students' mathematical connection abilities taught with a realistic mathematics approach (PMR) and conventional learning approach, a significant value of 0.127, because 0.127> 0.05

Abstract

This study aims to: 1) find out whether students' mathematical problem solving abilities that are taught with problem based learning are better than students who are taught by direct learning. 2) find out whether the mathematical problem solving ability of students who have high learning motivation is better than students who have low learning motivation. 3) find out whether there is an interaction between learning and student learning motivation towards students' mathematical problem solving abilities. This study uses a quasi-experimental method with a 2x2 factorial design. The study population was fifth grade students (five) in the odd semester of the 2017/2018 Academic Year at SDN 0407 Mondang which consisted of two classes with a sample of 50 students. The class used as the sample of the experimental group is class V A with 25 students and the control class is class V B with 25 students. Thus the sample selection is done by total sampling technique. Data was collected by student achievement test and student motivation instrument. The collected data was processed statistically using a two-way variance (anava) analysis technique with a significance level of 0.05. The results showed that (1) There was an influence of problem-based learning methods on the mathematical problem solving ability of Class V students of SD Negeri 0407 Mondang 2017/2018 Academic Year; (2) There is an influence of student learning motivation on the mathematical problem solving ability of fifth grade students of SD Negeri 0407 Mondang for the Academic Year 2017/2018; and (3) There is an interaction between problem-based learning methods and students' motivation to the mathematical problem solving ability of students of Class V of SD Negeri 0407 Mondang 2017/2018 Academic Year. Practically, this study recommends that teachers use problem-based learning methods in mathematics learning and pay attention to the level of student motivation so that the learning design is adjusted to that motivation level. Theoretically, this study contributes to adding knowledge related to problem-based mathematics learning in elementary schools. Further studies can deepen studies related to the suitability of student characteristics with the selected learning method because these aspects are indicated as one of the key factors for student learning success.

Abstract

This study aims to determine the effect of the Realistic Mathematical Education (RME) approach on the ability to understand mathematical concepts in class VIII students of SMP IT Al-Hijrah 2 Deli Serdang Private Middle School in the 2022/2023 academic year. The type of research used is Quasi Experimental with a Pretest-Posttest Control Group Design. The sample used was 35 students who were selected through a purposive sampling technique. Data collection techniques are carried out using test instruments. Data analysis technique is done by descriptive analysis. The results of the descriptive analysis show that the average value in the experimental class is 87.3935 and in the control class is 54.3639, which means that there is a difference in the posttest average scores in the experimental class and the control class. Based on the Independent Sample T-Test, the value of Sig. (2-tailed) of 0.000 < 0.05. The tcount value is 8.428 and the ttable value is 2.03452, which means that tcount > ttable then H0 is rejected and Ha is accepted. From the results of this study, it can be concluded that there is an influence of the Realistic Mathematical Education (RME) approach on the ability to understand mathematical concepts in class VIII students of Private Middle School IT Al-Hijrah 2 Deli Serdang.

Abstract

This research aims to find out the results of research analysis of students abilities through the Two Stay Two Stray (TSTS) type cooperative learning model from various literature, as well as to analyze the difficulties of students mathematical communication skills through the Two Stay Two Stray model. This type of research is descriptive qualitative and uses a literature study research method which was carried out at the Digital Library, Medan State University in July – September 2022. The instrument in this study was the author himself. The steps of this research are: (1) Designing the research. (2) Carry out the research design. (3) Analyze and provide conclusions on the results of the analysis. The analysis technique used in the selection of information related to data analysis techniques is the Miles and Huberman analysis technique. The data source used secondary data consisting of 5 journals. The conclusions of the results of this study show that: (1) The average results of tests of students mathematical communication abilities through the application of the TSTS model are: (a) The indicator of mathematical representation is 51.93%, (b) The indicator of writing/explaining mathematics was 40.31%, (c) The indicators describe is 37.94%. (2) There are several difficulties experienced by students and teachers are: (a) Students have difficulty connecting real objects, pictures, and diagrams into mathematical models, (b) Students lack confidence in communicating arguments and ideas in mathematical problems, ( c) Students are less thorough in working on questions, (d) Students have difficulty expressing mathematical ideas in the form of graphs, pictures, or tables, (e) Low student skills in understanding mathematical communication problems and drawing conclusions about mathematical communication problems, (f ) The role of the teacher is less than optimal in carrying out learning activities.
