Étienne Charles Wenger (born 1952)[1] is an educational theorist and practitioner, best known for his formulation (with Jean Lave) of the theory of situated cognition and his more recent work in the field of communities of practice.

Wenger initially came upon the concept of communities of practice when he was approached by John Seely Brown, to join the Institute for Research of Learning.

One of the first people to observe and study communities of practice, Etienne Wenger's work is applied in various fields.

According to Wenger, "Communities of practice are groups of people who share a concern or a passion for something they do and learn how to do it better as they interact regularly.

"[7] Wenger earned a Ph.D. in artificial intelligence, and worked with the Institute for Research on Learning to help apply his concept of communities of practice to education.
