Abstract

Latar belakang masalah penelitian ini adalah rendahnya kemampuan berpikir kritis dan disposisi matematis siswa yang disebabkan perangkat pembelajaran tidak mendukung kemampuan tersebut. Penelitian bertujuan untuk: (1) memperoleh perangkat pembelajaran yang valid dan efektif, (2) mengetahui peningkatan kemampuan berpikir kritis dan disposisi matematis siswa dengan menggunakan perangkat pembelajaran yang dikembangkan berbasis pendekatan penemuan terbimbing. Penelitian ini merupakan penelitian pengembangan. Model pengembangan yang digunakan adalah model 4-D dari Tiagarajan, dkk. Uji coba I di kelas VIII-6 dan uji coba II di kelas VIII-8 SMP Negeri 15 Medan. Perangkat Pembelajaran yang dikembangkan yaitu RPP, Buku Petunjuk Guru (BPG), Buku Siswa (BS), dan Lembar Kerja Siswa (LKS). Setiap perangkat memenuhi aspek validitas dan reliabilitas. Dari hasil pengembangan ini diperoleh bahwa: (1) Validitas Perangkat pembelajaran valid yaitu validitas RPP = 4,58, BPG = 4,63, BS = 4,66, dan LKS = 4,63 dan efektivitas perangkat pembelajaran efektif dilihat dari ketercapaian ketuntasan belajar siswa, aktivitas siswa dalam batas toleransi yang ditetapkan dan respon siswa terhadap pembelajaran dalam kategori baik; (2) persentase peningkatan kemampuan berpikir kritis siswa pada uji coba I adalah 12,5% dan pada uji coba II 20,6 %; serta rata-rata peningkatan disposisi matematis siswa pada uji coba I adalah 0,49 poin dan pada uji coba II adalah 0,54 poin.
