One way to improve the quality of math learning is by using technology. As a free, dynamic, and interactive mathematics application program, GeoGebra can support mathematics learning in schools. "GeoGebra was developed by Markus Hohenwarter in 2001. According to Hohenwarter and Fuchs, GeoGebra is very useful as a medium for learning mathematics," said Assoc. Prof. Dr. Hutkemri Zulnaidi from the Department of Mathematics and Science, Universiti Malaya.

Geogebra is very helpful in learning mathematics because Geogebra can be used for demonstration and visualization, as a construction tool, for mathematical exploration and discovery, as teaching material building software (authoring tools), and can be used to check the answers to mathematical problems. Working in Geogebra can be done using geometry input and algebraic input.

Hutkemri explained that learning Geogebra through online media is not as difficult as imagined. Several online learning methods include MyOT_G, Google Wall, Rothe_Q, Kadageo, and ValeaOff. With My_OT method, Hutkemri explained that students who use the My_OT method are more able to develop Propositional Logic than conventional methods. My_OT has the advantage of being more accessible anywhere at any time. Furthermore, students will think more creatively and more critically. Hutkemri also explained that students are more interested in mathematics and can improve Mathematical reasoning.(Author: Anton, Editor: Dedy, Tj.Lak)
