Alison, fair but firm definitely works. At the end of the day it is all about the students and their success. If your methods produce successful students then this would be where I would focus my attention with regard to what you what students to know. Nothing wrong with having a reputation for being "tough" but you also do not want students to be in fear before they even get to know you and your course. I would also recommend you talk with your champion students and get them to assist you in spreading the word that you are tough but you also get results and your students are highly successful.
