A Project That Goes Beyond the Steam Community
This week, we also released the first free demo of our educational spin-off,\nNro & Sci: Education, supported by Texas Instruments France, the IREM of Lyon, and the French Ministry of Education.
As the director of the IREM of Lyon puts it:
Nro & Sci intelligently demystifies mathematics.
Thats exactly what you can experience in this new demo.
Our Nro & Sci: Education concept also won over Texas Instruments France,\nwho believed in our vision and now support us in adapting the gameplay of Nro & Sci Integral Edition for classroom use.\nThanks to them, were offering a free demo to over 750,000 students and teachers on their maclasseti.fr platform.
When Souris-Lab presented the concept of Nro & Sci: Integral Edition and its ambition to adapt it for classroom use,\nwe immediately saw the projects potential.\nThe poetic universe and the richness of its gameplay offer a unique way to rediscover mathematics through play.\nTheir collaboration with the IREM of Lyon, the scientific rigor they bring, and the integration of engaging tutorials around our graphing calculators completely convinced us.\nThis partnership combines the pedagogical expertise of the IREM of Lyons teacher-researchers,\nthe technological know-how of Texas Instruments, and the creativity of Souris-Lab.\nBy welcoming Nro & Sci: Education on maclasseti.fr,\nwere offering over 750,000 students and teachers a new way to learn playful, accessible, and connected to our tools.\nThe recent institutional support through the Edu Up program of the French Ministry of Education further reinforces the credibility and reach of this ambitious project serving education.\n Carlos Coelho, Texas Instruments France Business Development & Alliances Manager
