Expectations for Student Effort
Describe how much time students should expect to invest in the course each week. Graduate courses should state: "For each hour of lecture equivalent, students should expect to have a minimum of two hours of work outside of class." Note that Global campus courses will automatically include credit hour equivalents in the syllabus.] [For each three hours of lab, students should expect to have a minimum of two hours of work outside of class. In this class, that would include preparation of lab reports, maintenance of lab notebooks, completion of lab assignments, and pre-work for the next lab session.
