Teaching is an important part of Jenkins' practice as an artist. Initially through his website tapesculpture.org he sought to popularize his casting method including the YouTube video, "How Babies Are Made".[23] Later he began holding workshops as a compoment of his installation projects in other cities. In 2009 he began extended masterclasses in Eastern Europe including Tashkent, Moscow, Perm and Baku.[24] Many student projects can be found online.Jenkins said the following about the illegal aspects of street art during an interview with Pitchaya Sudbanthad in 2005, "I think my point is that visual outliers are what’s needed to keep the environment stimulating, but unfortunately the only visual content that’s updated with any real frequency are commercial advertising spaces. This is why the ephemeral nature of street art is so essential—because it creates a visual heartbeat in the city by people who are living in it, rather than just marketing to it. But what does the city do with these works? They remove them as quickly as possible and threaten to put the people who make them in jail."[31]
