AbstrakMateri pecahan merupakan salah satu materi matematika yang rumit. Kerumitan pecahan tidak saja dialami oleh siswa, tetapi juga mahasiswa dan guru. Penyebabnya adalah penguasaan konsep pecahan yang rendah. Karena guru pada jenjang pendidikan Dasar memperkenalkan pecahan dengan metode ceramah dan langsung memberi contoh soal kemudian siswa mengerjakan soal latihan. Guru mengajarkan algoritma rutin dalam mengerjakan soal, Edo. I.S (2016). Metode ini dipraktekan secara turun temurun. Karena itu siswa merasa jenuh dan tidak tertarik belajar. Elly Risman (2008) mengatakan bahwa,” Ada tiga cara penyampaian yang efektif bagi anak, yakni dengan bermain, bernyanyi, dan bercerita. Sementara Pendekatan pembelajaran yang berlandaskan pada filosofi bahwa matematika merupakan aktivitas Insani adalah pendekatan Pembelajaran Matematika Realistik. Karena itu penelitian ini bertujuan untuk mengetahui bagaimana desain pembelajaran pecahan dengan menggunakan pendekatan Matematika Realistik Konteks Permainan Siki Doka (taplak). Adapun metode penelitian yang digunakan adalah Desain Riset yang dilaksanakan di SDN. Angkasa Kupang dan SDK. Kristen Tunas Bangsa Kupang pada siswa kelas III. Hasilnya adalah siswa sangat antusias dan menikmati seluruh aktivitas pembelajaran karena mereka belajar melalui kegiatan bermain, menggambar, mewarnai, menggunting dan menyusun kertas origami yang berwarna warni. Siswa bukan saja telah memahami konsep pecahan sederhana, membandingkan pecahan sederhana, dan memecahkan masalah yang berkaitan dengan pecahan sederhana tetapi juga mereka sudah terlibat dalam aktivitas yang berhubungan dengan konsep penjumlahan dan kelipatan pecahan.Kata Kunci: Pembelajaran Pecahan, Konsep Pecahan, Perbandingan Pecahan, Pembelajaran pecahan dengan RME, pembelajaran pecahan conteks permainan tradisional.AbstractFraction is one of hard subject of mathematics. Fractional complexity is not only experienced by students, but also students and teachers. They found difficulty to solve any mathematics problems related to fractions due to weak of fraction concept and disspointed learning method. Because teachers in elementary taught them using lecture method through routin algorthm. Teacher began the lessons by given short explanation, then some routin example provided on students’ text book. In the end of the lessons students did some exercise, Edo.I. S (2016). Therefore, students bored to follow all of learning process. Whereas Elly Risman (2008) said that there are three effective ways to teach children i.e. by playing, singing and storytelling. While Mathematics learning approach which assume that mathematics as human activity is Realistics Mathematics Education (RME). Therefore, this study aimed to design simple fraction learning trajectory using RME approach through traditional game namely siki Doka as a context. The Research method used in this research is Design Research which conducted in SDN Angkasa Kupang and SDK. Tunas Bangsa Kupang in the third grade students. The result showed that students were very enthusiastic and enjoy all the learning activities because they learned while playing, drawing, Coloring, cutting and arrange colorful origami paper. Students not only understand the concept of simple fractions, compare simple fractions, and solve problems related to simple fractions as well they are already involved in the activities to found the concept of fractional addition and its multiples.Keyword: Fractional Learning, Concepts of Fraction, comparing fraction, Fractional Learning using RME approach, fraction learning using traditional game.

Mathematical connection is the ability to make connections to understanding mathematical concepts that are associated with contexts outside of mathematics. Various studies revealed that the students' mathematical connection is still low; therefore, this study aims to describe the difficulties of junior high school students in mathematical connection ability. This research is a descriptive qualitative study. The study sample was 52 students from a junior high school in East Flores Regency. The methods used in this study were tests, observations, and interviews. The study results showed that the mathematical connection ability based on the three indicators of connection ability tends to be below. Students did not understand concepts that had been studying; easy to forget concepts, principles and procedures; not used to use concepts, principles and procedures; assume mathematics has nothing to do with other sciences; not accustomed to applying mathematical concepts in everyday life; lack of understanding about the story

The rapid and massive spread of COVID-19 in the world, including Indonesia, has greatly affected various fields of life, including education. Therefore, in order for the learning process to continue during this pandemic, a strategy is needed to meet educational needs during the pandemic. The online learning process or online (on the network) uses an application that can support distance learning namely google classroom. This of course requires students to be active and critical independently in studying the topics studied in learning activities. The research was conducted at SMK Negeri 3 Kupang with a population of all students of class XI majoring in Computer and Network Engineering. Samples were taken as many as 60 students. From the results of the analysis, there is an effect of using google classroom on learning independence as shown in the results of the statistical test, the value of Fcount = 5.74 > Ftable = 2.76 and the value of Sig. 0.002 < 0.05 so that H0 is rejected. There is no significant effect of using google classroom on student mathematics learning outcomes, as shown in the results of the statistical test, the value of Fcount = 2.59 < Ftable = 2.76 and sig. 0.61 > 0.05 so that H0 is accepted. There is an effect of using google classroom on independent learning and student mathematics learning outcomes as shown by the results of MANOVA statistical analysis, it is known that the statistical value of the Pillai's Trace test is 0.618 and the value of Fcount = 8.341 > Ftable = 2.18 and the value of Sig. 0.000 < 0.05 so H0 is rejected. And there is an influence between learning independence on students' mathematics learning outcomes, as shown in the results of a simple linear regression statistical test, it is known that the value of ttable = 2.00172 > tcount = 22.138 so that H0 is rejected.

Abstract Mathematics is a science with a broad concept. The breadth of concepts in mathematics, does not rule out the possibility that these concepts are interrelated. For example, in studying linear equations with one variable, students must first know the concept of algebraic operations. This study aims to describe the concept of mathematical connection ability, describe the learning strategies used to improve the mathematical connection skills of junior high school students, and provide an overview of learning designs to improve mathematical connection skills for junior high school students. The method used by the author is a literature review method. Based on the studies conducted, it can be concluded that the ability of mathematical connection is the ability of students to relate between topics in mathematics and then mathematics topics with other sciences or with everyday life. The strategy or model used in learning mathematics is an important part for an educator in planning learning designs that will be applied in the learning process. Therefore, it is important for further researchers to apply existing strategies or models to different materials, so that they can be studied further about students' connection abilities in the learning process.
