Stephen Downes is a specialist in online learning technology and new media. Through a 25 year career in the field Downes has developed and deployed a series of progressively more innovative technologies, beginning with multi-user domains (MUDs) in the 1990s, open online communities in the 2000s, and personal learning environments in the 2010s. Downes is perhaps best known for his daily newsletter, OLDaily, which is distributed by web, email and RSS to thousands of subscribers around the world, and as the originator of the Massive Open Online Course (MOOC), is a leading voice in online and networked learning, and has authored learning management and content syndication software. Downes is also recognized as a leading voice in the open education movement, having developed early work in learning objects to a world-leading advocacy of open educational resources and free learning. Downes is widely recognized for his deep, passionate and articulate exposition of a range of insights melding theories of education and philosophy, new media and computer technology. He has published hundreds of articles online and in print and has presented around the world to academic conferences in dozens of countries on five continents. Working with the National Research Council since 2001, Downes has been engaged in a series of leading-edge research and development projects related to e-learning. At the University of Alberta between 1999-2001 he built a learning and research portal for the municipal sector in that province, Munimall, and another for the Engineering and Geology sector, PEGGAsus. He also pioneered the development of learning objects and was one of the first adopters and developers of RSS content syndication in education. Downes introduced the concept of e-learning 2.0 and with George Siemens developed and defined the concept of Connectivism, using the social network approach to deliver open online courses to three thousand participants over two years. He developed some of Canada's first online courses at Assiniboine Community College in Brandon, Manitoba between 1995-1999. He also built a learning management system from scratch and authored the now-classic "The Future of Online Learning". Downes has been offering courses in learning, logic, philosophy both online and off since 1987, has 135 articles published in books, magazines and academic journals, and has presented his unique perspective on learning and technology more than 250 times to audiences in 17 countries on five continents. He is a habitual photographer, plays darts for money, and can be found at home with his wife Andrea and four cats in Moncton, New Brunswick, Canada.
