Abstract

Mathematical connection skills are very important to be developed in students because they can develop new mathematical ideas in solving mathematical problems, can connect mathematical concepts, and can see and relate problems from various different points of view. Facts in the field show that the students' mathematical connection ability is still low. One alternative that is assumed to help improve mathematical connection skills is the application of the Discovery Learning model. The purpose of this study was to determine the improvement of students' mathematical connection abilities after the Discovery Learning model was applied as a whole and based on indicators of mathematical connection ability. The research method used was a quasi-experimental design with a Pretest-Postest Control Group Design with a sample class VIIIA and VIIIB. Class VIIIA as many as 25 students as the experimental class and class VIIIB as many as 23 students as the control class. Data were collected using a mathematical connection ability test which was then analyzed using independent t-test and n-gain. The results of the study were: (1) The improvement of students' mathematical connection ability was better after being taught with the Discovery Learning model; and (2) there was an increase in the students' mathematical connection ability after the application of the Discovery Learning model for each indicator, namely the ability to connect between mathematical concepts increased by 44%; the ability to relate mathematics to other disciplines increased by 28%; and the ability to relate mathematics to everyday life increased by 36%.Keywords: Discovery Learning Model, Mathematical connection ability

Abstract

This study aims to determine the effect of realistic mathematics learning based on ethomathematics and conventional learning on the ability to understand mathematical concepts of junior high school students. The research method use is quasi experiment, with a pretest-posttest control group design. The population in this study were all students of class VII MTsS Darussaadah Cot Tarom, while the sampling was carried out using simple random sampling (by just randomizing the classes) so that class VII.1 was selected as the experiment class using realistic mathematics learning based on etnomathematics and class VII.2 as a control class using conventional learning. Data collection used a test sheet for understanding mathematical concepts which was then analyzed using an independent sample t-test via SPSS. The reserch results obtained that the velue of sig (2-tailed) independent sample t-test 0.0000.05. so that H0 is rejected and H1 is accepted, it can be concluded that the ability to understand mathematical concepts taught using etnomathematical-based realistic mathematical learning is better that the ability to understand mathematical concepts taught using conventional learning. The above conclusions are supported by the fact that during the learning process using realistic mathematics based on ethnomathematical associated whith local culture can increase understanding of awareness and attractiveness so as to increase students understanding of the benefits and concepts of mathematics in everyday life.Keywords: Realistic mathematics learning, Ability undertstanding of mathematical concepts, Ethnomathematics Banda Aceh..
