The development of calculus teaching materials using geogebra

Abstract

Calculus is one of the fields of mathematics that is the basis of mathematical thinking. Problems related to differential calculus experienced by students are visual ability in drawing graphics. Focus material on graphs of equations and functions. Therefore, researchers make innovations in learning by making teaching materials using GeoGebra. The research method used is research and development. The research subjects were 40 students in the Mathematics Education Study Program at Universitas Suryakancana. The results of the validation of media experts using the Kendall test, sig. = 0,020> 0.05 (Ho accepted) means that the calculus teaching material using GeoGebra is feasible to use. The results of the validation of the material using the Kendall test, sig. = 0,025 (Ho accepted) means that the material content is appropriate. The results of tests on 40 mathematics education study program students, an average percentage of 78% of students answered strongly agree and 15% answered agreed, meaning that calculus teaching material using GeoGebra is effectively used.
