AUTOGRAPH

Autograph is a very dynamic computer program. In windows

operation, its use offers 3 options, namely: (a) 1D for Statistics; (b) 2D for

Graphs, Coordinate Transformations and Geometry; (c) 3D for Graphs,

Coordinates and Transformations. Autograph has two levels of operating

systems, namely standard and advanced. The standard level provides a

very simple interface, while the advanced level provides more complete

options so that in solving problems, users are given the freedom to choose

options to be used in problem solving.

Autograph is a special program that many users consider to be more

powerful than Geogebra in learning mathematics (Tarmizi, 2009).

Autograph software is one of the newest products from London, England

which is capable of displaying quite complete menus including geometry,

algebra, has 2D and 3D graphing capabilities for topics such as

transformations, conic sections, slopes, and derivatives, and is able to draw

statistical graphs, functions, and vectors as well as to change the shape of

an object or shape.

According to Ahmadi (Rusdianto, et al: 2012) Autograph can

improve scientific discourse in mathematics class which leads students to

the learning experience of investigating and solving mathematical

problems. Autograph will help teachers and students to see the relationship

between visual and symbolic representations and scientific discourse

which in turn will create an environment to use the correct terms and

concepts studied. With this application, it is possible for users to modify

and simulate pre-plotted graphs, shapes or vectors to encourage concept

understanding.
