Massive open online courses (MOOCs) offer a unique platform through which Extension can provide valuable education. We explored The Meat We Eat, a MOOC designed to create a more informed meat consumer and increase perceptions of transparency surrounding meat production. Compared to pretest respondents (n = 490), students who completed the posttest (n = 226) had an improved attitude toward meat and slaughter, an improved perception of the meat industry's transparency, and increased knowledge. These findings suggest the relevance and value of MOOCs as Extension activities for improving knowledge and attitudes toward animal agriculture and other topics.
