Apart from the personal interest of the author in this topic, the present project is the response to a classical methodology which uses teaching materials promoting inequalities. Therefore, the feminist implementation offers a wide variety of materials in order to allow students to express and communicate by themselves taking into account the genuine social challenge such as is sexist or chauvinist system. The key objective of this pedadogy resides in fostering critical thinking of pupils through the reflection of experiential facts.
