To be fair, I always experience this the Sunday before the first day of school, so this is not a new feeling. Even after almost 20 years, I still worry:
- what will my students be like?
- how will they view me?
- what will each class' chemistry be like?
- will I do a good job?
- am I going to have any discipline issues already on the first day?
So I guess that these jitters are all part of being a teacher. I am sure that I will have difficulty getting to sleep tonight, and then once I do get to sleep, I also expect waking up every hour due to fear of sleeping through my alarm. I also know that once I get started tomorrow with students and get back into the zone of teaching, I will say to myself "Why was I so nervous?"
So to all you 1st-year teachers (and even veterans of 25 years), you are not the only one who is nervous about the first day of school!
