Hello. A friend of mine shared with me a great story that was on NPR on first year teachers. Here is the link. The mentor teacher referenced in the article also recently wrote a book of advice for teachers by teachers called, 'See Me After Class,' and she emails advice to new teachers who sign up, and, of course, tweets. She identifies this time of year as the critical time – between the end of the first six weeks and Thanksgiving break when first year teachers contemplate quitting.
Also, in the article is a link to phases of first year teachers. One of the phases is "disillusionment." This was a great article and I look forward to reading her book. Enjoy!
