TASKS WITH EDWARDS --VENN DIAGRAM FOR SIX SETS.

The article focuses on the development and educational application of tasks using the Edwards–Venn diagram for six sets, a model that employs axial and rotational symmetry to visualize complex set relationships. Created with GeoGebra software, this six-set Venn diagram divides the plane into 64 distinct regions and supports interactive tasks designed to enhance concept formation, logical reasoning, and visualization skills in learners. The authors present examples of tasks, including number classification and task composition, and discuss the model's use in diverse educational contexts such as museums, where it can facilitate self-assessment and engagement through augmented reality. An expert survey involving teachers and scientists indicated strong support for the educational value and usability of these digital resources, highlighting their potential to stimulate student interest and active participation in learning.
