Online courses at Johns Hopkins Engineering for Professionals provide many opportunities for student-instructor interaction. First, instructors are required to post their contact information in the course syllabus and to state how quickly students can expect to hear back from them. Instructors also use various communication and facilitation tools within the course management tool (i.e., Blackboard). Types of interaction typically include course announcements, instructor discussion forum postings, assignment feedback, and weekly, synchronous office hours. Instructors are encouraged to log in to their course site daily or at least five times a week.
