Abstract

Penelitian ini bertujuan untuk mendeskripsikan : 1) validitas perangkat pembelajaran berbasis masalah yang dikembangkan, (2)kepraktisan perangkat pembelajaran berbasis masalah yang dikembangkan, (3) efektivitas perangkat pembelajaran dengan menggunakan perangkat pembelajaran berbasis masalah yang dikembangkan, (4) peningkatan kemampuan komunikasi matematis siswa dengan menggunakan perangkat pembelajaran berbasis masalah, dan (5) peningkatan self-efficacy siswa melalui angket (6)Proses jawaban siswa dalam menyelesaikan tes komunikasi matematis. Penelitian ini merupakan penelitian pengembangan dengan model Dick and Carey. Ujicoba I dilakukan pada siswa kelas VII-1 dan ujicoba II di kelas VII-2 SMP Negeri 23 Medan. Instrumen penelitian ini adalah lembar observasi aktivitas siswa, kemampuan guru mengelola pembelajaran, angket respon siswa serta tes kemampuan komunikasi matematis. Perangkat pembelajaran yang dikembangkan (Buku Guru, Buku siswa dan LKS). Dari hasil penelitian diperoleh bahwa: 1) perangkat pembelajaran yang dikembangkan memenuhi kriteria valid, baik dalam validitas isi maupun konstruk. 2) perangkat pembelajaran yang dikembangkan memenuhi kriteria praktis, ditinjau dari : a) penilaian validator dan , b) keterlaksanaan perangkat pembelajaran. 3) perangkat yang dikembangkan telah memenuhi efektivitas proses pembelajaran, dimana: (a) persentase ketuntasan belajar siswa adalah 92,5% secara klasikal dari 40 orang siswa yang mengikuti tes dengan nilai minimal 2,67 (B-); (b) kadar aktivitas siswa telah memenuhi batas toleransi waktu ideal; dan (c) respon siswa terhadap proses pembelajaran sudah positif pada ujicoba I maupun ujicoba II; 4) terjadi peningkatan rata-rata kemampuan komunikasi matematis siswa pada postes ujicoba I ke ujicoba II ; (5) terdapat peningkatan self-efficacy siswa yang diujikan melalui angket; dan (6) proses jawaban siswa pada uji coba II lebih baik dari Uji coba I.
