Abstract

Penelitian ini sayalakukakan di SMPN Miomaffo Barat Kabupaten Timor Tengah Utara, Propinsi Nusa Tenggara Timur pada bulan Mei 2015.Tujuan penelitian ini adalah untuk menghasilkan perangkat pembelajaran LKS dengan menggunakan pendekatan matematika realistik yang baik pada materi transformasi di kelas VII SMP. Proses pengembangan perangkat pembelajaran LKS ini menggunakan model Plomp yang dikemukakan oleh Prof. Tjeerd Plomp (1997), yang terdiri dari 5 tahap yaitu a. Investigasi awal; b. Desain; c.Realisasi; d.Tes, evaluasi dan revisi; serta e. Implementasi. Tetapi dalam penelitian ini hanya dapat melakukan tahap 1 sampai dengan tahap 4. Hasil analisis yang telah dilakukan peneliti menunjukkan bahwa perangkat pembelajaran LKS dengan menggunakanpendekatan matematika realistik yang dihasilkan telah memenuhi kriteria perangkat yang baik yaitu dinyatakan valid oleh ahli, praktis yang dinyatakan dengan kemampuan guru mengelola pembelajaran dan aktivitas siswa, efektif yang dinyatakan dengan hasil belajar siswa dan respon siswa. Data-datanya dapat diuraikan sebagai berikut: a) Valid. Rata-rata total validasi LKScukup, yaitu3,29, dan dapat dipergunakan dengan revisi kecil. b) Praktis. ditunjukkan dengan adanya data kemampuan guru mengelola pembelajaran dalam kategori baik dengan ratarata 4,71, dan aktivitas siswa baik yaitu siswa mengikuti setiap langkah-langkah sesuai tahapan dalam RPP. c) Efektif, ditunjukkan dengan data respon siswa positif terhadap setiap aspek dengan rata-rata presentasenya adalah lebih dari 70%, tes hasil belajar memenuhi kriteria ketuntasan kelas.

Abstract

The development of the world globally in various fields of life has demanded intense competition. Therefore, every individual who inhabits this world needs to have certain competencies in order to be able to compete in this globalization era. Hence, each individual must be able to think at a high level (higher order thingking / HOT) especifically on math subjects. But the problems that occur, there are still many students who have difficulty in solving the problems in the form of higher order thinking (HOT) so that they have not been able to compete globally. To overcome this problem the researcher carried out a higher order thingking analysis on Algebraic material. This study aims at describing the analysis of higher order terms in Algebraic material. The method used were a test and interview of 3 informants in six schools based on students' levels of ability, namely high ability, moderate ability and low ability. The results showed that there were differences in solving HOT problems in students who had high, medium and low abilities.

Abstract

This study aimeds to determine the mathematical ability of vocational students in solving the HOT type three-variable linear equation system problems. This research was a qualitative descriptive study. The data collection methods were written tests and interviews. The subjects of this study were nine students of class XI Pharmacy, SMK St. Agustinus Kefamenanu, Province Nusa Tenggara Timur. Two students with low mathematical ability, two students with moderate mathematical ability, and twostudents with high mathematical ability were selected to be interviewed. The research suggest that, students with high mathematical ability and students with moderate mathematical ability are able to work on questions at the analyzing and, evaluating stage, but have not yet reached the creating stage. Students are still working on problems using the method given by the teacher. Students with low mathematical ability are only able to work on problems at the analyzing stage.

Abstract

Learning mathematics using a cultural approach is commonly known as ethnomatematics. Ethnomatematics is a mathematics learning approach that bridges mathematics learning through local culture. The purpose of this study was to explore the culture of Sonaf L.A.N Taolin and describe the mathematical concepts that exist in the building elements of Sonaf L.A.N Taolin. This type of qualitative research uses an ethnographic approach that aims to explore the mathematical concepts found in Sonaf L.A.N Taolin. The subject of this study was an informant, Raja Insana. The research instruments were human instruments, observation guidelines, and interview guides. Data analysis was carried out in three stages, namely data reduction, data display and conclusion drawing. The results of this study indicate that building elements such as poles, doors, and roofs from Sonaf L.A.N Taolin contain geometry concepts that can be implemented as a medium for learning mathematics on the material: flat shapes, spatial structures, similarities, geometric transformations (reflections).
