The stage following consists in to stablish a criterion on which they can select the option that better adjusts to its possibilities of execution. It is understood that this selection is accepted by the whole group.
The process continues when the students of the group develops a plan to perform their project choosen, specifying all the concerning details . At this stage, each group will prepare a complete full description of what they propose to do, indicating in adition, for example:
a) the greater amount possible of the contents of the disciplines to include, related to their project
b) the materials that will occupy

d) the distribution of the functions that each is committed to playing
After the planning stage, each group focussed on the implementation of its task, which, when completed, should be presented to the class. This presentation should also prepared, with all details of the case.
