Abstract

ABSTRACT This study intended to investigation the impovement of students mathematical communication by using Google SketchUp and direct Instruction, the interaction between students' learning ability and learning method in term of mathematical communication skills, and also students' attitudes toward Google SketchUp. The study used quasi experimental design and employed control group with pretest and control final test. The population of study was eight grade students at of one a public Junior High schools in Lembang and two classes was choosen as a sample. Experimental group was used Google SketchUp and control group was used direct Instruction learning. The data were collected though students understanding of mathematical communication test, Likert scales, and student journal. The data were analyzed using quantitative and qualitative. The quantitative data were analyzed using pretest and posttest and the normalized gain of mathematical communication, and also conducted test both of groups which are performed the mean difference test between two populations and two-ways ANOVA. The qualitative data were analyzed using students' attitudes toward Google SketchUp learning. The finding of this study suggested that Google SketchUp learning was effective in improving students' of mathematical communication . More over, result showed that there is interaction between students' learning ability (high, medium, and low) in terms of students' mathematical communication and also positive students' attitude toward Google SketchUp learning. Key words: Google SketchUp program and mathematical communication ABSTRAK Penelitian ini bertujuan untuk menelaah peningkatan kemampuan komunikasi matematis siswa yang mendapatkan pembelajaran dengan Program Google SketchUp dan pembelajaran langsung, interaksi antara pembelajaran yang digunakan dengan kategori kemampuan siswa dalam hal kemampuan komunikasi matematis siswa, serta sikap siswa terhadap pembelajaran dengan Program Google SketchUp. Desain penelitian ini adalah kuasi eksperimen dengan kelompok kontrol tes awal dan tes akhir. Populasi penelitian ini adalah seluruh siswa di salah satu SMP Negeri di Lembang dengan sampel penelitian siswa kelas VIII sebanyak dua kelas yang dipilih secara purposif. Kelompok eksperimen memperoleh pembelajaran dengan Program Google SketchUp dan kelompok kontrol memperoleh pembelajaran langsung. Untuk mendapatkan data hasil penelitian digunakan instrumen berupa tes kemampuan komunikasi matematis, skala sikap, dan jurnal siswa. Analisis data dilakukan secara kuantitatif dan kualitatif. Analisis kuantitatif dilakukan terhadap data tes awal, tes akhir, dan gain ternormalisasi kemampuan komunikasi matematis, serta terhadap data tes kedua kelompok dilakukan uji perbedaan rata-rata antara dua populasi dan ANOVA dua jalur. Analisis kualitatif dilakukan untuk menelaah sikap siswa terhadap pembelajaran Program Google SketchUp. Hasil penelitian menunjukkan bahwa peningkatan kemampuan komunikasi matematis siswa yang mendapatkan pembelajaran Program Google SketchUp lebih baik daripada siswa yang mendapatkan pembelajaran langsung, terdapat suatu interaksi antara pembelajaran yang digunakan dengan kategori kemampuan (tinggi, sedang, dan rendah) siswa dalam hal kemampuan komunikasi matematis, serta sikap siswa positif terhadap pembelajaran dengan Program Google SketchUp.

Abstract

Abstract: The purpose of this study investigated and understand impact of classroom action research- based lesson study in determining the formula of circle area. This kind a classroom action research in the subject of money and bank in order to participate in solving problems related materials. The Subject of this study is Grade 6 student in academic year 2017/2018. The implementation classroom action research conducted in two cycles comprising Planning, Implementation, observing, and reflection stages. The result of this study that classroom action research-based lesson study in determining the formula of circle area has been well implemented including the completeness of the learning tools and preparing the Lesson Plans before teaching on each teaching material. Based on the results of the implementation of classroom  action  research-based  lesson  study  can  be  concluded  that  classroom  action research-based lesson study can improve student achievement.
