Abstract

This research is motivated by low ability of elementary students’ mathematical creative thinking. Thus this research was done by tangram.The aims of this research are 1) examining to improve student’s mathematical creative thinking and 2) examining interaction effect between student’s prior mathematics ability toward student’s mathematical creative thinking by tangram. The research utilized a quasi experimental  with Nonequivalent Control Group Design. The instruments comprised of mathematical creative thinking test. The quantitative analysis is used a two-way ANOVA. The result  of quantitative analysis shows better increasing mathematical creative thinking ability by tangram than by conventional teaching in fifth grade of SDN Pamulang 01 South Tangerang. Futhermore, there was no interaction effect between student’s prior mathematics ability toward student’s mathematical creative thinking. Penelitian ini dilatarbelakangi oleh rendahnya kemampuan berpikir kreatif matematis siswa sekolah dasar, sehingga peneliti melakukan penelitian dengan menggunakan media tangram dalam proses pembelajaran. Adapun tujuan penelitian ini adalah 1) Mengkaji peningkatan berpikir kreatif matematis siswa di kelas yang mendapat pembelajaran dengan penggunaan media tangram lebih baik daripada siswa di kelas yang mendapatkan pembelajaran biasa. 2) Mengkaji pengaruh interaksi antara penggunaan media tangram dengan Kemampuan Awal Matematis (KAM) siswa terhadap peningkatan berpikir kreatif matematis. Metode penelitian yang digunakan adalah Kuantitatif dengan Quasi Experimental dan desain dalam penelitian ini Nonequivalent Control Group Design.. Hasil penelitian menunjukkan bahwa terdapat perbedaan peningkatan yang signifikan penggunaan media tangram terhadap berpikir kreatif matematis siswa di kelas V SDN Pamulang 01 Tangerang Selatan. Hal ini terbukti dari perhitungan menunjukkan hasil uji ANOVA dua jalur nilai signifikansi sebesar 0,000 kurang dari taraf signifikansi 0,05. Selanjutnya hasil penelitian juga menunjukkan bahwa tidak terdapat interaksi terhadap kemampuan berpikir kreatif siswa. Hasil penelitian ini semoga bermanfaat kepada pihak-pihak yang terkait.

Abstract

The purpose of this study was to develop E-Comic-based mathematics teaching materials on the topic of multiplication and division with the Realistic Mathematics Education (RME) approach. This research is a research and development using the Hannafin and Peck development model. This model consists of three stages, namely needs assessment, design, development and implementation. The subjects in this study were students of class 3A SDN Pinang 2 Tangerang City. The results research obtained included 1) material expert validation got 95,38% with very valid criteria, 2) linguist validation got 87,5% with very valid criteria, 3) media expert validation got 97,5% with very valid criteria. Assessment of student responses 1) small group test got 95,41% with high criteria, 2) large group test got 99% with high criteria. Based on the results of the assessment, the E-Comic-based mathematics teaching materials developed are valid and can be used as additional teaching material for teaching the concept of multiplication and division.Tujuan penelitian ini adalah mengembangkan bahan ajar matematika berbasis E-Comic pada topik perkalian dan pembagian dengan pendekatan Realistic Mathematics Education (RME). Penelitian ini merupakan penelitian pengembangan (Research and Development) dengan menggunakan model pengembangan Hannafin dan Peck. Model ini terdiri atas tiga tahap, yaitu penilaian kebutuhan, desain, pengembangan dan implementasi. Subjek pada penelitian ini adalah peserta didik kelas 3A SDN Pinang 2 Kota Tangerang. Analisis data yang digunakan adalah deskriptif kuantitatif dengan persentase. Hasil penelitian yang didapatkan antara lain 1) validasi ahli materi mendapatkan 95,38% dengan kriteria sangat valid, 2) validasi ahli bahasa mendapatkan 87,5% dengan kriteria sangat valid, 3) validasi ahli media mendapatkan 97,5% dengan kriteria sangat valid. Penilaian respon peserta didik 1) uji kelompok kecil mendapatkan 95,41% dengan kriteria tinggi, 2) uji coba kelompok besar, mendapatkan 99% dengan kriteria tinggi. Berdasarkan hasil penilaian tersebut maka bahan ajar matematika berbasis E-Comic yang dikembangkan valid dan dapat dijadikan sebagai bahan ajar tambahan untuk pengajaran konsep perkalian dan pembagian.

Abstract

This study aims to improve students' geometrical thinking skills through the media of Augmented Reality learning. Augmented Reality learning media is a learning medium that combines a real object with a virtual object that has a 3-dimensional (3D) shape and is designed to resemble the actual environment that aims to provide any information to its users with an interesting, interactive, and real-time delivery. This study is a quasi-experimental or quasi-experimental study with the design used by researchers, namely the nonequivalent control group design. The population in this study were 202 students of class V SDN Cireundeu 01. The sample of this research was 52 students consisting of 26 experimental class students and 26 control class students who were determined through a purposive sampling technique. The instrument used in this study was in the form of a geometric thinking ability test. Data analysis of students' geometry thinking skills was done by t-test using SPSS 16. The results of the analysis showed that the thinking ability of students in geometry taught using Augmented Reality learning media was higher than students who were taught using concrete media. Therefore the results of this study indicate that mathematics learning by using Augmented Reality learning media has a significant role in increasing students' geometrical thinking abilities
