PENERAPAN ASESMEN FORMATIF UNTUK MENINGKATKAN KETERAMPILAN PROSES SAINS MATERI UNSUR, SENYAWA, DAN CAMPURAN PADA SISWA KELAS VIII

APPLICATION OF FORMATIVE ASSESSMENT TO IMPROVE ELEMENTAL, COMPOUND, AND MIXED MATERIAL SCIENCE PROCESS SKILLS IN GRADE VIII STUDENTS

Penelitian ini bertujuan untuk mendeskripsikan peningkatan keterampilan proses sains, keterlaksanaan pembelajaran dengan penerapan asesmen formatif, dan respon peserta didik terhadap pembelajaran penerapan asesmen formatif. Metode penelitian yang digunakan adalah pre-eksperimental design dengan rancangan one group pretest and posttest design. Penelitian ini dilakukan di MTsN 2 Kota Surabaya. Subjek dalam penelitian ini adalah 31 siswa kelas VIII-B. Teknik pengumpulan data penelitian ini dengan metode tes, observasi, dan angket. Instrumen yang digunakan untuk mengumpulkan data adalah lembar soal pretest-posttest, lembar observasi, dan lembar angket respon siswa. Teknik analisis data yang digunakan yaitu analisis N-gain Score, Uji Normalitas Shapiro-Wilk, Uji hipotesis menggunakan uji Wilcoxon Signed Rank Test untuk peningkatan keterampilan proses sains dan analisis deskriptif kuantitatif untuk keterlaksanaan pembelajaran dan respon siswa. Hasil dari penelitian menunjukkan bahwa keterampilan proses sains siswa yang didapatkan meningkat, dengan seluruh siswa rata-rata mendapatkan N-gain berkategori sedang. Selain itu, pada uji hipotesis menggunakan Uji Wilcoxon Signed Rank Test didapatkan bahwa terdapat perbedaan hasil tes keterampilan proses sains antara sebelum dan sesudah dilakukan pembelajaeran penerapan asesmen formatif. Keterlaksanaan pembelajaran pada setiap pertemuan mendapatkan hasil sangat baik dan tanggapan siswa terhadap pembelajaran mendapatkan respon sangat positif.

This study aims to describe the improvement of science process skills, the learning implementation of formative assessment, and the response of students to learning the application of formative assessment. The research method used is pre-experimental design with one group pretest and posttest design. This research was conducted at MTsN 2 Surabaya City. The subjects in this study are 31 students in grades VIII-B. The data collection technique of this research wey by test, observation, and questionnaire methods. The instruments used to collect data were pretest-posttest question sheets, observation sheets, and student response questionnaires. The data analysis techniques used were N-gain Score analysis, Shapiro-Wilk Normality Test, hypothesis test using the Wilcoxon Signed Rank Test to improve science process skills and quantitative descriptive analysis for the implementation of learning and student response. The results of the study showed that the science process skills of the students obtained increased, with all students on average getting N-gain in the medium category. In addition, in the hypothesis test using the Wilcoxon Signed Rank Test, it was found that there was a difference in the results of the science process skills test between before and after the evaluation of the application of formative assessment. The implementation of learning at each meeting got very good results and the students' response to learning received a very positive response.
