Online classrooms are frequently categorized into three types; enhanced, hybrid, and fully online. An enhanced course would include course-related materials. This information is typically for the students viewing purpose only and is not a requirement. The hybrid course provides online activities as a means for reducing seat time. This does not reduce the students study requirement or the rigor of the class.
The last type, fully online courses, students are not required to come to the campus. The faculty and student may never meet face-to-face. If they meet, in order to be considered fully online, there so be a maximum of three meeting. In a fully online course all requirements for reading, discussion, homework, and assessments are conducted online.
