Penelitian ini bertujuan untuk: (1) mendeskripsikan kelayakan perangkat pembelajaran IPA berbasis inkuiri berdasarkan hasil penilaian dosen ahli dan guru IPA, dan (2) mengukur keefektifan perangkat pembelajaran IPA berbasis inkuiri dalam meningkatkan critical thinking skills dan scientific attitude siswa SMP. Metode yang digunakan dalam penelitian ini adalah research and development (R&D) yang mengadaptasi model penelitian pengembangan Borg & Gall. Subjek uji coba produk terdiri atas 34 siswa kelas VII SMPN 14 Yogyakarta dan 52 siswa SMPN 1 Piyungan. Pengumpulan data menggunakan metode wawancara, observasi, angket, dan tes. Data dikumpulkan melalui pedoman wawancara, lembar observasi, lembar angket, dan soal tes. Data kelayakan perangkat pembelajaran dianalisis dengan menggunakan konversi skor skala 4. Keefektifan perangkat pembelajaran dalam meningkatkan critical thinking skills dan scientific attitude siswa dianalisis dengan multivariate analysis of variance (MANOVA) dan gain score. Hasil validasi dan uji coba produk menunjukkan bahwa (1) perangkat pembelajaran IPA layak digunakan dalam pembelajaran dan (2) efektif dalam meningkatkan critical thinking skills dan scientific attitude siswa.
