By this stage in the process you have already decided how to deliver your content and designed opportunities for students to interact with you and with each other. Before teaching the class, consider how you are going to convey your unique personality, facilitate interactions, and communicate with students.
It helps to begin by establishing clear guidelines for the amount of time you plan on spending in the course and how frequently you will respond to student questions. Before you begin you may want to take the Faculty Self-Assessment: Preparing for Online Teaching. You can look at an example of a completed self-assessment or review the Assessing Online Facilitation Instrument.
