In the context of the hybrid OLCC model, lecturer refers subject-domain expert who creates course material and interacts online with students from classes at multiple schools. Prior to offering the class, the lecturer interacts with facilitators in the development of material, customizing it to the needs of the facilitator's class. The lecturer need not be involved with academia and could be an expert with experience in government or industry. The lecturer is not responsible for grades, but is responsible for lesson content. The lecturer is required to interact with students when the lecturer's material is being delivered to a class.
