| A resource for scholars and others interested in media literacy. The materials were originally developed by graduate students enrolled in a course taught by Professor Renee Hobbs at Temple University's School of Communication and Theater, and has been further developed by succeeding versions of the same course. The course looks at media literacy in a wide context, and is of relevance to secondary education, tertiary education, research and education outside the formal sector. |
