The big advantage of the recurrence here is to allow the student to focus just on the fundaments of the construction, in which she does not need to apply the script without recurrence too many times which would be necessary to get good representations of the fractal. The principle of this approach is the identification of the basis to the construction of geometric fractals and in which these objects must be applyed the recurrence.

A fractal must present a characteristic of “self-semblance”, which means that if it was possible to put a magnifying glass in a given piece of it, the resulting image would be identical to the original.

The work with students of middle school can follow the black-box method, providing a ready-to-use script and asking them to discover the specific properties based on counting for example, on the fractal tetra-circleif applyed typing ka positive integer, how many circumferences will show up?

The name fractal was proposed by Benoit Mandelbrot in the 80’s, derived from the latim word “fractus”, which means “part” or “broken”.

Mandelbrot used this term to represent geometric objects of non-integer dimensions, as it was done in conventional geometry: Citations Publications citing this paper. ifeom

Just for being new, mainly to high school students, probably the reader already knows one recorrent function: Developing tools in iGeom: This type of didactic approach can be improved by the igrom of a Interactive Geometry System that allows the construction of igepm or geometric algorithmsand even more if the system have recurrencelike iGeom.

With the use of scripts recurrentsone can obtain geometric constructions that describe fractalsand from the properties of these constructions can explore the concepts listed above.

DurelliSeiji Isotani. For example, the concept of algorithm or even of software programming can be introduced challenging the students to deduce the scripts that could generate a given fractal. The principle of this approach is the identification of the basis to the construction of geometric fractals and in which these objects must be applyed the igeim.
