Abstract

Abstract This study aims to determine whether there is an effectiveness of applying RME learning model on the mathematical communication skills at the eighth grade students of SMP Swasta Advent Barus. The research used an experimental method by applying one group pretest posttest design. The sample of this study is taken by using total sampling technique, the eleventh grade students of SMP Swasta Advent Barus which includes 35 students. Observation and tests are used in collecting the data. Observation sheets show the applying of RME learning model has an average of 2.93 (good category) while students' mathematical communication skills before applying RME learning model has an average of 64.70 (enough category) and after applying RME learning has an average of 72.13 (good category). Furthermore, based on the calculation of the t-test (SPSS of version 2017) it shows the value of Sig. (2-tailed) is 0.000 < 0.005, classical completeness is 51.43% and the N-Gain value shows 0.27 (low category). It means, there is any effectiveness of appying RME learning model on students' mathematical communication skills in the low category at the eighth grade students of Barus Adventist Private Junior High School.

Abstract

Ethnomathematics is a breakthrough in the concept of mathematics in which there is a culture associated with mathematics. The presence of mathematics that blends cultures will make a very large contribution or contribution to learning mathematics. The purpose of this study is to identify and describe or describe a mathematical object contained in a traditional game of marbles and what are the benefits of learning mathematics. This research is research qualitative using ethnographic methods. The instruments used by researchers in this study were interviews, documentation, and literature studies directly with the informants. The data analysis techniques used by researchers are data reduction, data presentation, data analysis, and data exposure. The results of the study show that the traditional game of marbles has ethnomathematics related to mathematical concepts including geometric concepts such as circles, balls, triangles, and the, concept of distance. These mathematical concepts can be used to introduce and understand the concepts of geometry and distance through local culture

Abstract

The purpose of this study was to examine the comparison of the quality of learning mathematics through the NHT and STAD models. This type of research is a quasi-experimental. The population in this study were all students of class VII SMP SMP Putri Yatama Mandiri in the 2021/2022 academic year and the samples in this study were taken by Saturated Sampling, namely class VIIA which was taught through the NHT model with a total of 25 students and class VIIB which was taught through the STAD model with a total of 25 students. The research design was a pretest-posttest control group design, which involved two classes that were given a pretest and a posttest. Data collection techniques are observation sheets of the implementation of learning and student activities, learning achievement tests, student response questionnaires. The results showed: 1) the average pretest score of students through the NHT model was 29.44 (very low) with a standard deviation of 6.01, 100% did not achieve individual mastery, meaning that classical mastery was not achieved, 2) the average score the average posttest of students through the NHT model is 85.20 (high) with a standard deviation of 5.35, 100% of students achieve individual mastery, meaning that classical mastery is achieved, 3) the average score of students' pretest through the STAD model is 38.08 (very low) with a standard deviation of 7.49, 100% obtained did not achieve individual completeness, meaning that classical mastery was not achieved, 4) the average posttest score of students through the STAD model was 81.6 (medium) with a standard deviation of 6.14, it was found that 23 students or 92% achieved individual mastery, meaning that classical mastery was achieved, 5) the average percentage of student response questionnaires that answered yes on NHT was 94.5% and on STAD 97%, meaning that 75% of students had fulfilled answer YES, and 6) the average gain is 0.79 on NHT and 0.70 on STAD. Thus the quality of learning mathematics through the application of the NHT model is not the same as learning mathematics through the application of the STAD model in class VII students of SMP Putri Yatama Mandiri Islamic Boarding School.
