PENGARUH PENGGUNAAN MEDIA PEMBELAJARAN BISKUIT PECAHAN BERBASIS PJBL TERHADAP HASIL BELAJAR MATEMATIKA MATERI PECAHAN DI SD NEGERI MAULAFA

This study examines the effect of the Project-Based Learning (PJBL) model using fraction biscuit media on the mathematics learning outcomes of fourth-grade students in the topic of fractions. The research employed a one-group pretest-posttest design, involving 29 students as the experimental group. Date were collected through learning outcome tests and analyzed using normality test, homogeneity test, paired sample t-test, and N-Gain analysis. The results showed a significant improvement in students' learning outcomes after the treatment was given (p = 0.000 < 0.05), with an average N-Gain score of 0.4878, which falls into the medium category. It is concluded that the PJBL model using fraction biscuit media is effective in improving students' learning outcomes in the topic of fractions.
