Numedeon

Best known for creating the children's educational web site "Whyville", Numedeon has also developed a number of other immersive online learning environments for other demographics and purposes.

[2] Whyville was launched in 1999 as an educational Internet site geared towards children aged 8–14 to engage its users in learning about a broad range of topics, including science, business, art and geography.

Its users ("Whyvillians") engage in virtual world simulation-based games and role play sponsored by a wide range of governmental, non-profit and corporate entities.

[3] Educational research based on Whyville has recently been published in the 2013 publication of the book Connected Play: Tweens in a Virtual World, written by Yasmin B. Kafai, Deborah A.
