ASK QUESTIONS OR COMMENT. If you've reviewed all the messages and announcements, guidelines and directions, and still can't find the answer to your question, email your instructor and classmates for help. In a F2F classroom, the instructor is able to "read" nonverbal cues such as frowns, nods, wrinkled brows, head tilts, squirming, etc., and he/she uses these to adjust the presentation. In a virtual classroom, these cues are absent. Your questions and comments will help to clarify the requirements for a given assignment.
