Abstract

Bahan ajar merupakan salah satu komponen terpenting yang harus ada didalam proses pembelajaran. Salah satu bahan ajar yang dapat digunakan yaitu lembar kerja siswa. LKS merupakan salah satu bahan ajar yang digunakan oleh pendidik dalam proses belajar-mengajar dengan bentuk bahan ajar yang lebih praktis, menarik, serta mempermudah peserta didik dalam menerima materi. LKS yang dikembangkan merupakan LKS berbasis etnomatematika dengan konteks rumah tembakau pada materi transformasi geometri kelas XI. Prosedur pengembangan yang digunakan mengikuti model pengembangan ADDIE (Analysis, Design, Development, Implementation, Evaluation). Penelitian ini disesuaikan dengan keadaan masa pandemi, sehingga penelitian hanya menggunakan uji validasi ahli dan kepraktisan. Ahli yang digunakan adalah ahli materi, ahli desain, dan ahli pendidikan matematika. Didapat rata-rata kevalidan 85.6% dengan kriteria sangat valid. Untuk kepraktisan diperoleh rata-rata kepraktisan 83.2% dengan kriteria sangat praktis. Kata Kunci: Etnomatematika, LKS, Pengembangan Teaching materials is one of the most important components that should appear in the learning process. One of teaching materials that can be used is student worksheet. Student worksheet is one of teaching materials used by educator in the learning process with a more practical teaching materials, interesting, and simplify students to receive material. Student worksheet that were developed is student worksheet based etnomathematic to the context tobacco house to the matter transformation geometry class XI. Procedure the development of which used follow model of ADDIE (Analysis, Design, Development, Implementation, Evaluation). This research adapted to the state of the pandemic, so research using only the validation experts and practicality. The experts are the matter, the design, aand the math education. Obtained the average validation 85.6% with perfectly valid criteria. Redard for practicality obtained the average 83.2% with very practical criteria. Kata Kunci: Development, Ethnomathematics, Student Worksheet.

Abstract

This research aims to describe students’ mathematical representation skills in solving numeracy problem with profession context. This is qualitative descriptive research with 12 students for its research subjects. There are four steps in analyzing the data, those are data collection, data condensation, data display, and conclusions. To check the validity, researchers used techniques triangulation. This research shows that, among those 12 subjects, there are four types of model in solving numeracy problem with profession context. Those are first, students use visual and external representation; second, they perform visual, verbal, math model, and internal representation; third, they use verbal, visual, and external representation; and fourth of all, they use verbal and external representation. To make this result fruitfull, other researchers can try to design mathematics learning activities to train students’ mathematical representation skill such that when students solve numeracy problems, they will not face any difficulties.
