Abstract

Abstract: This study aims to describe the Physics test item parameters in Work and Energy and describe students’ abilities using the item response theory approach (IRT) dichotomous scoring. This research is quantitative descriptive. The research subjects were 1175 high school class XI students in West Java and Banten provinces consisting of 450 male students and 725 female students. The instrument used was Physics of Work and Energy as many as 25 items in multiple choices with dichotomous scoring. Student response data with dichotomous scoring were analyzed using the item response theory approach using the BILOG-MG program. The results showed that most of the items fit the 2PL model. Subsequent analysis of the items’ characteristics indicates that all items have different power and a level of difficulty in the good criteria. Keywords: item parameters, item response theory, physics test. Abstrak: Penelitian ini bertujuan mendeskripsikan parameter butir soal Fisika pada materi Usaha dan Energi dan mendeskripsikan kemampuan peserta didik dengan menggunakan pendekatan teori respon butir (Item Response Theory, IRT) penskoran dikotomus. Penelitian ini merupakan penelitian deskriptif kuantitatif. Subyek penelitian sebanyak 1175 siswa SMA kelas XI yang tersebar di provinsi Jawa Barat dan Banten yang terdiri 450 siswa laki-laki dan 725 siswa perempuan. Instrument yang digunakan berupa soal Fisika materi Usaha dan Energi sebanyak 25 butir berbentuk multiple choice dengan penskoran dikotomus. Data respon  siswa dengan penskoran dikotomus dianalisis menggunakan pendekatan teori respon butir menggunakan program BILOG-MG. Hasil penelitian menunjukkan bahwa butir soal paling banyak fit dengan model 2PL. Analisis berikutnya mengenai karakteristik butir soal menunjukkan bahwa keseluruhan butir memiliki daya beda dan tingkat kesulitan dalam kriteria good. Kata kunci: parameter butir, teori respon butir, tes fisika. DOI: http://dx.doi.org/10.23960/jpmipa/v22i1.pp1-9
