Desain penelitian yang digunakan adalah desain R&D Borg dan Gall. Penelitian dilakukan di SDN Semanu III, SDN Karangrejek II, dan SDN Gombang II, Kabupaten Gunungkidul. Instrumen pengumpulan data menggunakan pedoman wawancara, lembar observasi, lembar validasi ahli, angket respon guru, skala respon siswa, dan skala karakter tanggung jawab. Keefektifan produk diuji melalui quasi experiment. Data dianalisis secara despkriptif kualitatif dan kuantitatif melalui uji beda dengan taraf signifikansi 0,05. Hasil penelitian ini berupa lembar kerja siswa yang layak digunakan berdasarkan penilaian ahli media dan ahli materi dengan kategori “sangat baik”. Produk yang dikembangkan efektif meningkatkan karakter tanggung jawab siswa. Hal ini dibuktikan uji beda postskala kelas eksperimen 1 dengan kelas kontrol perbedaan reratanya signifikan pada nilai t hitung 2,119 dan two-tails significance pada 0,040. Pada uji beda post skala kelas eksperimen 2 dengan kelas kontrol, perbedaan reratanya signifikan pada nilai t hitung 2,164 dan two-tails significance pada 0,036 dengan taraf signifikansi 0,05.
