Penelitian ini bertujuan untuk menghasilkan produk Lembar Kerja Peserta Didik (LKPD) berbasis Etnomatematika yang berkualitas baik pada materi Segiempat dan Segitiga. Untuk mengetahui kualitas dari LKPD yang dihasilkan dilihat dari tiga aspek yaitu kevalidan, kepraktisan dan keefektifan. Metode yang digunakan dalam penelitian ini yaitu research and development(R&D) dengan model pengembangan four-D(4-D) yang dimodifikasi menjadi 3D tahap yaitu define, design, dan develop. Instrumen yang digunakan untuk mengukur kualitas LKPD yaitu angket lembar validasi untuk mengukur kevalidan, wawancara, angket respon guru dan respon peserta didik untuk mengukur kepraktisan, dan tes untuk mengukur keefektifan.Hasil dari penelitian ini menunjukkan kualitas LKPD memenuhi kriteria kevalidan dengan skor rata – rata keseluruhan sebesar 4,8 dan kualitas LKPD memenuhi kriteria kepraktisan dengan skor rata – rata keseluruhan sebesar 4,73 sertapersentase ketuntasan tes peserta didik sebesar 77,7 % memenuhi kriteria keefeektifan.Dengan demikian Pengembangan LKPD berbasis Etnomatematika pada materi segiempat dan segitiga berkualitas baik dan dapat digunakan dalam pembelajaran matematika.
This survey was conducted to describe the mathematical literacy of state junior high school students in Kupang, East Nusa Tenggara province. Not only was it done due to the low performances of Indonesian 15-year-old students in PISA but also since there was not any research studies that had been done before to map the mathematical literacy of 15-year-old students in Kupang. This study used two-stage cluster randomized sampling to choose six-state junior high schools representing six sub-districts around Kupang. A total of 377 ninth-grade students were selected to become the respondents in this survey. They were tested using fifteen mathematical literacy problems directly adopted from PISA 2012 and some development researches items. The results showed that the mathematical literacy of state junior high school students in Kupang generally was in a low category. When we looked into three process domains as well as four content domains, the math literacy of students was also classified as either a low or a very-low-category. The results of this study can provide valid and actual data for society and the government regarding the math literacy of students in Kupang.
The environment can become a source of learning in a process of mathematical learning related to the real world. One source learning in the environment is cultural. Mathematical lessons that studied educated participants at school are sometimes different to important transatic problems that encountered in everyday life, makes it more difficult learning participants linking the links of furatic concepts that are formal with issues of culture. Etnomathematics connects cultures with mathematics learning. The purpose of this research is to obtain the description of the value of the impostor’s value and growing up to the cultural society of Waibalun. This type of research is a qualitative research with the Etnographic design. Data collection by observation, interviews and documentation. The subject in this study is three person taken Purposive against public figures who learn and understand well about indigenous homes. The object of this research is the Waibalun indigenous home. The results of data analysis show that a) Etnomathematical activity in the process of making Waibalun indigenous homes, that is measuring, counting and designing; b) The mathematical values were found in the Waibalun indigenous home consist of, the angle, rectangle, triangle, trapezium, tube and reflections.
Alat peraga matematika merupakan media pembelajaran yang dapat membantu siswa dalam mengkongkritkan konsep yang abstrak sehingga menjadi mudah untuk dipahami. Oleh karena itu guru wajib dituntut untuk mampu menghasilkan alat peraga sebagai media pembelajaran yang dapat meningkatkan minat dan motivasi belajar dari siswa. Hal ini perlu dilakukan guru agar mampu memanfaatkan media pembelajaran yang sederhana dalam mentransferkan materi ajar sehingga siswa mampu menangkap dan memahami materi yang disampaikan dengan baik sehingga tujuan pembelajaran yang dirancang dapat tercapai. Tujuan dari pengabdian ini untuk membantu guru-guru dan siswa agar dapat memanfaatkan alat peraga matematika dalam pembelajaran. Metode yang digunakan berupa metode praktek, diskusi serta observasi. Kegiatan pengabdian ini dilaksanakan di SD Inpres Oebola Dalam Kecamatan Fatuleu Kabupaten Kupang Nusa Tenggara Timur. Dengan sasaran peserta guru-guru dan siswa. Pelaksanaan kegiatan pemanfaatan alat peraga matematika sebagai media pembelajaran dapat berjalan dengan lancar sehingga meningkatkan antusiasme dari peserta dengan memberikan berbagai macam respon positif, serta peserta dapat memahami dan menggunakan alat peraga matematika dalam memahami konsep. Oleh karena itu perlu adanya bimbingan dan pelatihan bagi para guru agar mampu menghasilkan media pembelajaran yang baik sehingga mampu diterapkan dalam kegiatan pembelajaran di kelas untuk meningkatkan minat dan mitivasi belajar siswa
This survey aims to describe the mathematical literacy of state junior high school students in Kupang city, East Nusa Tenggara province. It was done not only due to the low achievement of Indonesian 15-year-old students in PISA but also because there are no surveys which had been done before to map the mathematical literacy of students in Kupang city. A total of 377 respondents who were the ninth grade students representing six state junior high schools in Kupang were collected by two-stage cluster randomized sampling. The students were assessed using fifteen problems adopted from PISA 2012 and some development researches with a product of mathematical literacy problems so that those items were highly reliable to measure students mathematical literacy. The categorization of students mathematical literacy was carried out using Mamdani’s Fuzzy Inference method. The input of fuzzification was a score of three process domains assessed by those fifteen problems, specifically formulating, employing, and interpreting. The output of defuzzification was students mathematical literacy score used to determine the category of students mathematical literacy. The results showed that the mathematical literacy of state junior high school students in Kupang city was generally classified as a low category.
