I have taught both Marketing and Education for 20 years now. In one Marketing department I taught in, more than half the faculty also had degrees in education (most were adult education). The two fields really come out of social sciences and have the same theories, but different terms. I find it interesting, for example, that Rogers is used a lot by educators these days in terms of acceptance of educational technology, since I taught Rogers as a fundamental concept in marketing. Both fields require that you know who the target audience is and build on an individual's strengths, identify what he or she needs (need gap), and follow up after the service (education or purchase). I often borrow emerging concepts from both and apply it to the other field.
