Playproject
Read full descriptionHide full description
Play project is an educational video game that aims to increase player awareness on environmental sustainability and on the best practices to adopt to save the plant. IC students Socrate Mallardo and Szkola Podstawowa played a pivotal role in the realisation of the video game. In the activities that led to its realisation the students were guided by Paidea and A.M.E.F.E. The game was made thanks to an Erasmus+ grant. The PLAY project stems from the will to address one of the biggest threats we’re currently facing: climate change. Due to the fact that we are responsible for the level of emissions of greenhouse gasses, we consider it crucial to educate the future generations to choose greener alternatives to reduce the impact we have on the planet, and we intend to do so by using an innovative methodology aimed at making students develop digital abilities as well as at upskilling teachers.
