As you set out to create an online course, start by trying to express the unique benefits your course will offer, including why a student should choose it over those offered by other educational providers.
Consider what prompted you to consider creating the course. Perhaps it was suggested by existing students to solve a problem for them, or perhaps it was proposed to solve a departmental problem, e.g. revenue generation or research dissemination. Whatever the reasons, capturing this information in a value proposition will enable your course design to solve those original problems and meet your students’ needs effectively.
