Abstract

Mentally retarded children or also called children with intellectual disability are children with below average intelligence who experience obstacles in adaptive behavior in the form of taking care of themselves and carrying out activities of daily living. Children with intellectual disability need special education and services to help them achieve optimal development. Children with mild intellectual disability require three basic skills, such as reading, speaking and arithmetic. The implementation of learning in the classroom, especially in learning mathematics requires learning modifications, so that they are in accordance with the individual conditions of intellectual disability students. Intellectual disability students have obstacles to think about something abstract, so in the preparation of learning programs the teacher is expected to; (1) understanding the characteristics of mild intellectual disability students, (2) conducting assessments, (3) being creative in modifying learning methods.

Abstract

Tujuan penelitian ini adalah untuk menganalisis kemampuan literasi matematis siswa dalam online learning pada masa pandemi covid-19. Data dikumpulkan menggunakan teknik tes. Instrumen tes disusun berdasarkan indikator kemampuan literasi matematis dan telah memenuhi kriteria valid dan reliabel. Penelitian ini melibatkan 68 siswa kelas VII di suatu SMP di Lampung. Pengambilan subjek penelitian dilakukan secara purposive dengan mempertimbangkan saran guru dan analisis awal. Analisis data dilakukan secara deskriptif. Hasil penelitian menunjukkan bahwa kemampuan literasi matematis siswa dalam online learning masih rendah yang ditandai dengan rata-rata skor tes kemampuan literasi matematis siswa yaitu sebesar 46,46 dan sebanyak 67,64% skor siswa berada dibawah rata-rata tersebut. Sementara itu, persentase capaian pada masing-masing indikator juga masih rendah. Jawaban yang diberikan siswa menunjukkan bahwa, sebanyak 80,05% siswa masih kesulitan dalam memilih dan membandingkan strategi untuk memperoleh penyelesaian, 64,06% siswa kesulitan dalam menggunakan penalaran untuk mengaitkan informasi yang diperoleh dari suatu permasalahan dengan konsep yang telah dimiliki, dan sebanyak 78,12% siswa mengalami kesulitan dalam menggunakan atau memanipulasi rumus atau prosedur dalam penyelesaian permasalahan kontekstual. Mengingat betapa pentingnya kemampuan literasi matematis, seorang guru harus mampu merancang pembelajaran agar dapat membantu siswa mengembangkan kemampuan literasi matematis.

Abstract

The purpose of this study is to explore Ethnomathematics of Geometry concepts in Kedatun Keagungan traditional house architecture. It is hoped that students will more easily explore understanding of mathematical abstractness through visual representations in familiar cultural forms. Learning mathematics by linking the surrounding culture so that learning is more meaningful for students. This research is a qualitative research with an ethnographic approach. Data collection techniques begin with observation, compiling and validating instruments, documentation studies and FGD. Data analysis technique uses the Spradley model. Based on the research results, it was found that Ethnomathematics in the Kedatun Keagungan traditional house has applied mathematical concepts both to the components of the house building and the ornaments inside which include: (1) the concept of geometry which consists of shapes, shapes and angles, (2) the concept of Geometry Transformations consisting of Symmetrical properties, Translation properties, Reflections, and Dilations. The results of this research can be used as a reference in developing teaching materials on Geometry material so that learning becomes more meaningful.
