Abstract

abstract The aims of this study is to describe the effectiveness of using Realistic Mathematical Education (RME) approach on students’ mathematical problem solving ability on the topic of the system of linier equation two variables at the tenth grade students of SMK Negeri 1Batang Angkola. This research was conducted by applying experimental method with 30 students as the sample and they were taken by using simple random sample technique from 130 students. Test and observation were used in collecting the data. Based on descriptive analysis, it was found (a) the average of using RME approach was 2.8 (good category) and (b) the average of students’ mathematic problem solving ability on the topic of the system of linier equation two variables before using RME approach was 49.9 (poor category) and after using RME approach was 85.9 (very good category). Furthermore, by using pair sample ttest and help SPSS version 17, the result showed the significant value was less than 0.05 (0.000<0.05). It means, RME approach was effective used on students’ mathematic problem solving ability on the topic of the system of linier equation two variables at the tenth grade students of SMK Negeri 1Batang Angkola. Keywords: RME approach, mathematical problem solving ability, the system of linier equation two variables

Abstract

Abstract This study aims to know whether there is the effectiveness of using Reciprocal Teaching learning model on students’ mathematical communication ability on the topic solid figure at the eighth grade students of MTs. Al-Mukhtariyah Sunagi Dua Portibi. The research was conducted by applying experimental method (one group pretest post test design) with 30 students as the sample and they were taken by using simple random sampling technique from 130 students. Observation and test were used in collecting the data. Based on descriptive analysis, it could be found (a) the average of using reciprocal teaching learning model was 3.00 (good category) and (b) the average of students’ solid figure achievement before using reciprocal teaching learning model was 52.38 (fair category) and after using reciprocal teaching learning model was 83.33 (very good category). Furthermore, based on inferential statistic by using pair sample ttest (SPSS 22), the result showed significant value was less than 0.05(0.000<0.05). It means reciprocal teaching learning model was effective used on students’ mathematical communication ability on the topic solid figure at the eighth grade students of MTs. Al-Mukhtariyah Sunagi Dua Portibi. Keywords: reciprocal teaching learning model, students’ mathematical communication ability

Abstract

Abstrak This study aims to describe of using realistic mathematical learning on students’ mathematical creative thinking ability on the topic solid figure at the eighth grade students of SMP Negeri 7 Padangsidimpuan. The research was conducted by applying experimental method (one group pretest post test design) with 25 students as the sample and they were taken by using simple random sampling technique from 153 students. Observation and test were used in collecting the data. Based on descriptive analysis, it could be found (a) the average of using realistic mathematical learning was 3.5 (very good category) and (b) the average of students’ solid figure achievement before using realistic mathematical learning was 61.64 (enough category ) and after using realistic mathematical learning was 78.92 (good category). Furthermore, based on inferential statistic by using pair sample ttest (SPSS 17), the result showed significant value was less than 0.05(0.00 < 0.05). It means realistic mathematical learning was effective used on students’ mathematical creative thinking ability on the topic solid figure at the eighth grade students of SMP Negeri 7 Padangsidimpuan. Keywords: Realistic Mathematical Learning, Mathematical Creative Thinking Ability
