About the post: Drawing on and challenging more familiar ideas such as citizen science and civic tech, the term citizen technology refers to technologies that are governable by and for citizens. For the author, the concept matters not only because it questions power in the production and application of technology, but also because of its practical relevance to education and other domains.
