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".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.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."
In a later interview with Brian Sherwin in 2009 he said, "There is opposition, and risk, but I think that just shows that street art is the sort of frontier where the leading edge really does have to chew through the ice. And it's good for people to remember public space is a battleground, with the government, advertisers and artists all mixing and mashing, and even now the strange cross-pollination taking place as street artists sometimes become brands, and brands camouflaging as street art creating complex hybrids or impersonators. I think it's understanding the strangeness of the playing field where you'll realize that painting street artists, writers, as the bad guys is a shallow view. As for the old bronzes, I really don't see them as part of what's going on in the dialogue unless addressed by a new intervention."
Jenkins gives a lecture presentation titled The Human City that compares humans to blood cells and streets and veins to arteries and sidewalks. He sees street art as a nutritious element rather than a virus.
