We are following this model with LearningLine (www.learninglineapp.com). We offer an optional "class" format where an instructor is available to answer questions and review homework. With most eLearning, when students hit a topic they don't understand, they have to figure it out themselves. Some will quit when they hit this wall. Our instructors are there to help students keep going. No more web searches for help, just send a question and an instructor will answer and even get on Skype to explain in person.
