Abstract

Penelitian ini bertujuan untuk mengetahui perbedaan kemampuan komunikasi matematis antara siswa yang menggunakan model Problem Based Learning berbasis etnomatematika dengan pembelajaran konvensional, dan respons siswa terhadap pembelajaran dengan menggunakan model Problem Based Learning berbasis etnomatematika. Metode yang digunakan dalam penelitian ini adalah eksperimen dengan desain penelitian menggunakan pola desain Non Equivalent Control Group Design dan teknik pengambilan sampel menggunakan Sampling Purposive. Populasi dalam penelitian ini adalah seluruh siswa kelas VIII di salah satu SMP Negeri di Kabupaten Kuningan Jawa Barat tahun ajaran 2016/2017 sebanyak lima kelas sedangkan sampel dalam penelitian ini adalah dua kelas VIII yaitu kelas VIII E sebagai kelas eksperimen dan kelas VIII B sebagai kelas kontrol yang masing-masing sebanyak 20 siswa. Hasil penelitian menunjukkan bahwa terdapat perbedaan kemampuan komunikasi matematis antara siswa yang pembelajarannya menggunakan model Problem Based Learning berbasis etnomatematika dengan pembelajaran konvensional setelah diberi perlakuan dan respon siswa terhadap pembelajaran matematika dengan menggunakan model Problem Based Learning berbasis etnomatematika mendapatkan respons yang positif dari siswa

Abstract

This research aimed to explore learning obstacles when students are given a Trigonometry problem in the mathematical understanding ability. Learning obstacles are constraints faced during learning and result in less than optimal learning. The given trigonometric material is just about the number and the difference of the cosine sinus. Trigonometry material given based on students' mathematical understanding ability. The ability of mathematical understanding based on 2 indicators is the ability of instrumental understanding and the ability of relational understanding. This research was conducted on students of class XI IPA 1MAN 3 Majalengka. This research method using qualitative approach by analyzing student answer result. The results of this study found some barriers to learning both are instrumental understanding and relational understanding.

Abstract

This research is motivated by the low understanding of students in studying the object of geometry study. The media that had previously been used in the form of a spatial framework made of bamboo or iron turned out to take up quite a lot of space and was not practical to carry in large quantities. Therefore, efficient and practical media are needed to help visualize concrete objects in learning. This research aims to implement Augmented Reality (AR)-assisted learning media on the material of three-dimensional shapes. This study uses an explanatory qualitative method. The participant in this study was one student from one of the junior high schools in the Cirebon Regency. Data collection techniques used are through interviews and documentation. The analysis technique consists of three stages: data reduction, data presentation, and concluding. The results showed that the AR application could make it easier for the student to understand the material and solve the problem of three-dimensional shapes. However, the student still has a little difficulty using the application and is a little confused when identifying the parts of the cube because the image of the shape raised by the application is still not clear. This research implies that AR applications can make students' spatial abilities better.

Abstract

This study aims to explore the misconceptions that occur in group theory learning conducted by pre-service mathematic teachers.  This research is part of a long research from abstraction in learning group theory: study of hermeneutic phenomenology on pre-service mathematics teachers.  This research method uses case study in qualitative research.  Data obtained in the form of Focus Group Discussion (FGD) videos and pdf files of partisipan diaries.  The findings of this study indicate a misconception on group as set and subset as subgroup and on the inverse element as only one over in multiplication.  These two misconceptions show from misunderstanding and misperseption.

Abstract

ABSTIIAKPcnelitian ini bertujuan untuk mengetahui pembelajaran dengan menggunakan model pembelajnran koeperaiif tipe TOT dapat meningkatkan kcmampuan pcmahaman matemaus siswa. Penelitian ini dilaksanakan di SMP Negeri 1 Lemahabang Kabuparcn Cirebon. Populasi pada penelitian ini adalah seluruh slswa kelas VIII SMPNegeri I Lemahebang. Kelas yang djJttdikan sampel dalam penelitien Ini sebanyak 2 kelas dari 8 kelas yang ada dengan mengambil sampel secara purposif. Masing-masing kelas sebaayak 33 siswa, kelas VIII B sebagai kclas eksperimen dan kelas VIII C sebagai kelas kontrol. Hasil pcnelitian menunjukkan bahwa pembelajaran dengan meuggunakan model pembelajaran kooperatif tipe TGT dapat meningkarkan kemampuan pemahaman matemaiis secara signifikan berdasarkan hasil uji hipotesis dengan menggunakan uji t yang nilainya 0.047 < 0,05. Secara deskriptif statistik juga dapat dilihal rata-rata peningkatan pemahaman pada kelas eksperimen sebesar 0,45 dan peningkalan pemahaman pada kelas komrol sebesar 0,35.
