PENILAIAN BERFIKIR KRITIS DAN KARAKTER DEMOKRATIS SISTEM POLITIK INDONESIA DENGAN METODE ROLE PLAYING BERBASIS KONSERVASI

Abstract

Penelitian ini menggunakan pendekatan Research and Development dengan tujuan untuk memotret penilaian pembelajaran yang sudah ada, mengembangkan instrumen penilaian pembelajaran dan menguji validitas, reliabilitas serta keefektifan produk. Pengembangan instrumen mengacu pada model Borg and Gall. Instrumen ini dirancang untuk mengukur ranah afektif (karakter demokratis) dan ranah kognitif (kemampuan berfikir kritis). Teknik pengumpulan data dengan metode tes, dokumentasi, observasi, wawancara, dan angket. Analisis data pada produk awal divalidasi oleh pakar untuk mendapatkan validitas isi. Selanjutnya, instrumen diujicobakan secara terbatas kepada peserta didik di SMA Negeri 1 Welahan Jepara. Hasil ujicoba instrument kemampuan berfikir kritis diukur validitas dengan rumus product moment. Sedangkan uji reliabilitas menggunakan rumus alpha. Tingkat kesukaran soal dan daya pembeda juga diukur. Pada instrument penilaian karakter demokratis yang diukur adalah validitas dan reliabilitas. Hasil pengukuran menunjukkan instrument penilaian pembelajaran yang dikembangkan valid, reliabel, praktis dan efektif.

This study used Research and Development (R&D) whose objective were to highlight the existing learning assessment and to develop a new learning assessment by testing validity and reliability, as well as the effectiveness of the well-developed product. This study referred to Borg and Gall model. The instrument of this study, that is the developed product, was organized to assess the affective domain (democratic character) and the cognitive domain (critical thinking ability). Additionally, the methods of data collection were using tests, documentation, observation, interviews, and questionnaires. The data analysis of the preliminary product was validated by some experts to obtain the content validity. Afterwards, the well-developed product was only tried out to the students of State Senior High School 1 of Welahan-Jepara. The try out result of critical thinking ability was analyzed by using the formula of ‘product moment’ to measure the validity. Meanwhile, the reliability test was using the formula of ‘alpha’. Furthermore, the difficulty level of the items and discrimination power were also measured. Moreover, the instrument of democratic character assessment also measured the validity and reliability. Finally, the resultsof this study showed that the instrument of well-developed learning assessment was valid, reliable, practical, and effective.
