GeoGebra : Aplikasi Membuat Media Pembelajaran Matematika Interaktif

Download Aplikasinya Disini

GeoGebra is an interactive geometryalgebra, and calculus application, intended for teachers and students. Most parts of GeoGebra are free software. GeoGebra is written in Java and thus available for multiple platforms. Many parts of GeoGebra have been ported to HTML5 by using theGoogle Web Toolkit.[1]

Its creator, Markus Hohenwarter,[2] started the project in 2001 at the University of Salzburg, continuing it at Florida Atlantic University (2006–2008),Florida State University (2008–2009), and now at the University of Linz together with the help of open-source developers and translators all over the world. Currently, the lead developer of GeoGebra is Michael Borcherds, a secondary maths teacher.

After a successful Kickstarter campaign, GeoGebra plans to expand their offerings to include an iPad and Android version.[3]

Dynamic geometry, algebra and calculus

GeoGebra is dynamic geometry software. Constructions can be made with points, vectors, segments, lines, polygons, conic sections, inequalities, implicit polynomials and functions. All of them can be changed dynamically afterwards. Elements can be entered and modified directly on screen, or through the Input Bar. GeoGebra has the ability to use variables for numbers, vectors and points, find derivatives and integrals of functions and has a full complement of commands like Root or Extremum. Teachers and students can use GeoGebra to make conjectures and prove geometric theorems.

Main Features

  • Next to the algebra two graphics views
  • All main fields of the Mathematics science is represented in the software trought tools
  • GeoGebra allows to rotate and animate any object.
  • Scripting possibility using the input line commands.
  • Dynamic Color options are adjustable
  • Built in spreadsheet capability with extended skills

Exporting

Constructed projects can be exported in several formats. Dynamic applets can be directly uploaded to GeoGebraTube,[4] exported to html (as a single file suitable for use in a virtual learning environment (VLE),[5] such as Moodle). Possible direct export to HTML5 or Animated GIFSVG vector images can be further edited using third party software, e.g. InkscapeEMF vector formatscan be directly imported in several Office applications. There are also options for exporting to the system clipboard, PNGPDFEPSPGF/TikZ and Asymptote.

GeoGebra can also create code that can be used inside LaTeX files in order to create that same images that GeoGebra generates, through the PSTricks package, the PGF/TikZ packages, orAsymptote code.

GeoGebraTube

GeoGebraTube is the official repository website of GeoGebra products and GeoGebra related free resources.[6] Workin from 2011 june, and contain more than 250 (in 2013 march) various product like interactive presentation, games and lessons etc. made by GeoGebra. [7]
