Abstract


Penelitian ini bertujuan untuk mengembangkan komponen dan instrumen penilaian otentik berbasis contextual teaching and learning (CTL) pada tema Indahnya Negeriku Subtema Keindahan Alam Negeriku kelas IV SD 1 Kadipiro, dan mengetahui kualitas dari instrumen penilaian otentik yang sedang dikembangkan. Penelitian pengembangan ini mengacu langkah yang dikembangkan oleh Borg & Gall. Validitas instrumen menggunakan validitas isi dengan Aiken’ V, reliabilitas instrumen menggunakan Cronbach Alpha. Tingkat kesukaran butir soal menggunakan proportion correct, dan daya pembeda soal menggunakan korelasi point biserial. Instrumen penilaian terdiri dari 6 komponen, yaitu: topik pembelajaran, tugas peserta didik, penilaian sikap, penilaian pengetahuan, penilaian ketrampilan, dan rubrik penilaian. Penilaian ahli menunjukkan produk pada kategori “Baik”. Validitas isi instrumen penilaian otentik berkategori “Valid”. Reliabilitas instrumen penilaian otentik berkategori “Reliabel” dengan Cronbach Alpha > 0,7. Tingkat kesukaran soal dikategorikan “Baik” dengan indeks 0,25-0,75; dan daya pembeda soal dapat “diterima” dengan indeks ≥0,20.
