Abstract
Penelitian ini bertujuan untuk mengonstruksi tes keterampilan proses sains (KPS) berbentuk pilihan ganda pada materi elastisitas dan hukum Hooke yang mengukur tujuh indikator KPS dan menganalisisnya menggunakan teori respon butir. Metode penelitian yang digunakan adalah mixed methods dengan The Exploratory Sequential design. Instrumen penelitian yang digunakan dalam penelitian ini adalah lembar validasi ahli dan instrumen tes keterampilan proses sains. Analisis dalam penelitian ini didasarkan pada hasil validasi oleh lima ahli yang terdiri dari ahli dalam pembuatan instrumen, ahli materi dan guru serta hasil uji lapangan terhadap 167 partisipan dari tiga sekolah di kabupaten Bandung. Hasil analisis validasi ahli dengan menggunakan graded response models (GRM) menunjukkan bahwa tes KPS dapat dinyatakan valid berdasarkan puncak fungsi informasi yang berada pada rentang -2 sampai +2. Data hasil uji coba lapangan dianalisis menggunakan teori respon butir model 3 parameter logistik. Model ini dipilih karena memiliki puncak fungsi informasi tertinggi. Berdasarkan hasil analisis kurva karakteristik tes diperoleh bahwa tes KPS memiliki nilai daya pembeda (a) sebesar 1,19 yang termasuk dalam kategori baik, tingkat kesukaran (b) sebesar 0,19 yang termasuk dalam kategori baik dan faktor tebakan semu (c) sebesar 0,17 yang dikategorikan baik. Pada tes KPS ini, kurva fungsi informasi dan kurva standard error of measurement (SEM) berpotongan pada jangkauan kemampuan pada rentang -1,59 sampai 2,73. Hal ini menunjukkan bahwa tes keterampilan proses sains materi elastisitas dan hukum Hooke reliabel untuk mengukur tingkat keterampilan proses sains partisipan dengan kategori kemampuan rendah sampai dengan kategori kemampuan sangat tinggi. Kata Kunci: konstruksi tes, analisis tes, keterampilan proses sains, teori respon butir. This research aims to construct and analyze multiple-choice scientific process skills (SPS) tests on elasticity material and Hooke's law that measure seven SPS indicators using item response theory. The research method used is mixed methods with The Exploratory Sequential design. The research instruments used by this research dalma are expert validation sheets and science process skills test instruments. The analysis in this study was based on the results of validation by five experts consisting of experts in instrument making, material experts and teachers as well as the results of field trials on 167 participants from three schools in Bandung district. The results of expert validation analysis using graded response models (GRM) show that the SPS test can be declared valid based on the peak of the information function which is in the range of -2 to +2. Data from field trials were analyzed using the theory of item response model 3 logistic parameters. This model was chosen because it has the highest peak of information functions. Based on the results of the analysis of the characteristic curve of the test, it was obtained that the SPS test had a differentiating power value (a) of 1.19 which was included in the good category, a difficulty level (b) of 0.19 which was included in the good category and a pseudo-guess factor (c) of 0.17 which was categorized as good. In this SPS test, the information function curve and the standard error of measurement (SEM) curve intersect in the range of capabilities in the range of -1.59 to 2.73. This shows that the material science process skill test elasticity and Hooke's law are reliable to determine the level of science process skills of participants with low ability categories to very high ability categories. Keywords: Test Construction, Test Analysis, Scientific Process Skills, Item Response Theory.
