Abstract

The need to visualize concepts and support the materials in Mathematics learning by forming the pictures or by using existing draw, becoming what is needed by the students in improving their mathematical development and understanding. GeoGebra can combine dynamic visualization of geometry and the results of mathematical calculations simultaneously. The author examines the definite integral concept material of course, to then be explored with GeoGebra so that it is easily understood by students. The author studies the procedures for using GeoGebra, studies and constructs the concept of definite integral concepts, into a simulation and visualization in the form of GeoGebra files, which are ready to be used in the learning of definite integral concepts.

Abstract

The aim of this paper is to present the statistical model simmulation about the definite integral concept based on upersum and lowersum random partitions by using geogebra. The random partitions of the uppersum and lowersum in determine the value of definite integral is used to find out the statsitical distribution of its generated random variable. Based on Kolmogorov Smirnov Test, the random variable data of subinterval partitions on uppersum and lowersum by using goegebra followed the certain statistical distribution. The random partitions of uppersum and lowersums followed Burr 4 parameter, Log-Pearson 3, and Pearson 6 distributions.
