PENGARUH PEMBELAJARAN MELALUI LUMIO BY SMART TERHADAP MATHEMATICAL RETTENTION SISWA PADA MATERI LINGKARAN

This research seeks to explore the impact of learning using the Lumio by smart platform on students' mathematics retention in circle material in class VIII SMP 01 Islam Jember. The research employed an experimental method with a quasi-experimental design. Posttest only control group. The research sample consisted of two classes, each consisting of 20 students. One class designated as the experimental group using learning via Lumio by smart, while the other class was utilized as a control group using conventional learning.
