In a profession which relies on the person’s decision-making ability, teaching and teacher development rarely discusses the effects of lack of sleep and its impact. Yet, with all the decisions that teachers make each day, they are constantly drawing on their energy pool. This is especially true for younger teachers who are often required to teach multiple subjects and usually have more extra-curricular expectations. Maybe educators need to pay more attention to the effects and some of the implications for the classroom and the school. It’s still early in the school year and putting together a plan now will pay dividends when the days are much shorter, the sun isn’t shining and the work is piling up.
