Cathleen, Your are right. You set the tone with your actions/words. You serve as a role model in all capacities. How you develop and organize the syllabus and course say something about you. If you expect your students to be organized and check their email or LMS daily, you have to do the same. If you expect your students to respect others, you must to the same. It's OK to jump in (particularyly after several students have answered questions on a discussion board) and ask another question to enhance the critical thinking. Thanks for your input.
