Training of Teachers at Farel Education Centre and Prima Quantum Tutoring in Using Geogebra

Low results from studying mathematics at the Farel Education Center and the Prima Quantum tutoring can indicate a poor understanding of mathematical concepts among students. This community service activity aims to provide additional insights to teachers as participants in media and mathematics learning aids using the GeoGebra application. Teachers' ability to understand mathematical concepts can be improved to help students understand mathematics more effectively. Participants in this community service activity were the Farel Education Center for Teachers and the Prima Quantum tutoring in Jakarta. There are three phases of action: the preparation, implementation, and evaluation to implement this Community service activity.
