Penerapan Evaluasi Pembelajaran Kimia Berbasis Gamifikasi Kahoot untuk Mengukur Hasil Belajar Siswa SMA Muhammadiyah Majenang pada Materi Asam Basa

Abstract

Chemistry teachers at SMA Muhammadiyah Majenang commonly face low student engagement during conventional, paper-based evaluation of acid-base material, which contributes to students' low mastery of this abstract chemical concept. This study aims to determine the effectiveness of Kahoot-based gamified learning evaluation in measuring and improving students' cognitive learning outcomes on acid-base material. A pre-experimental one-group pretest-posttest design was used, involving 32 eleventh-grade science students selected through purposive sampling. Data were collected using a 20-item multiple-choice test administered through Kahoot and a student response questionnaire, then analyzed using the N-gain score and a paired sample t-test. The average N-gain score was 0.58 (medium category), and the paired t-test showed a significant difference between pretest and posttest scores (p < 0.05). In addition, 84.6% of students gave a "very good" response to the Kahoot-based evaluation. Kahoot-based gamified evaluation effectively improves student learning outcomes and can be used as an alternative formative assessment tool for acid-base material.
