Pengembangan LKM, RME, Literasi MatematikaAbstrak
Penelitian ini bertujuan untuk memperoleh perangkat pembelajaran berupa Lembar Kerja Mahasiswa berbasis pendekatan Realistic Mathematics Education yang valid dan efektif untuk meningkatkan kemampuan literasi matematika mahasiswa pada mata kuliah Geometri Analitik Bidang. Proses pengembangan LKM menggunakan model 4-D Thiagarajan. Instrumen-instrumen dalam penelitian ini adalah: (1) lembar validasi perangkat pembelajaran LKM, (2) lembar observasi, (3) angket respons mahasiswa, dan (4) tes berupa pretest dan posttest yang mengukur kemampuan literasi mahasiswa pada materi Geometri Analitik Bidang. Tes ini digunakan untuk mengukur tingkat kemampuan literasi mahasiswa yang terdiri dari level 1-6 sesuai dengan framework PISA. LKM berbasis Realistic Mathematics Education yang dikembangkan divalidasi oleh dua ahli kemudian dianalisis dengan validitas isi Gregory. Hasil penelitian menunjukkan bahwa LKM yang dikembangkan dinyatakan valid dan efektif berdasarkan penilaian validator dan hasil uji coba yang dilaksanakan. Kevalidan perangkat lebih dari 75% atau V > 75%. Ini menunjukkan bahwa LKM yang dihasilkan berada pada kategori valid atau inferensia yang dilakukan adalah sahih. Keefektifan perangkat ditunjukkan dengan terpenuhinya 3 dari 4 indikator kefektifan yang ditetapkan, antara lain: (1) Rata-rata kemampuan literasi matematika mahasiswa berada pada level “sedang†(2) terpenuhinya 7 dari 9 kategori aktivitas siswa, (3) Semua mahasiswa memberikan respon positif sebesar 100% dari tiap aspek yang direspon.
