Peningkatan Hasil Belajar Materi Fungsi Komposisi dan Invers Berbantuan Youtube di Masa Tatap Muka Terbatas

This study aims to determine whether learning assisted by YouTube learning videos can improve student learning outcomes in the material of composition functions and inverse functions. This research is a Classroom Action Research conducted at Madrasah Aliyah Negeri 1 Indramayu. The subjects in this study were students of class X MIPA 1, totaling 23 students. The instrument used in this research is a formative test given every cycle to measure the increase in student learning outcomes in mathematics. The data processing learning outcomes obtained an average of 49.02 in the first and76.82 in the second.
