As I sit here on my "summer vacation," I realize that taking up the topic of teachers and work time is a dangerous one, though I did spend a couple of hours today working on next year's curriculum and sequence planning (in the sun while my sons splashed in the inflatable pool). Lest you think I am complaining about the time that I put in as a teacher, (1) my father was [is] a teacher, so I saw firsthand growing up that the work was not limited to the contracted day and (2) even knowing that expectation, I still chose this profession.
Ultimately, the conclusion of the time study was that a typical teacher spends an average of 1.4 hours at work (on site) beyond their contracted work day. Looking back on my own schedule this past year, at typical day included a 6:30am arrival and a 3:30pm departure, so I'm in line with the average in terms of time spend on the job at school. Unless I am misreading it, what this study did not seem to take into consideration was the work that gets taken home each evening and on the weekends during the school year. The study (linked above) parsed out how that at-work time was used but didn't go beyond time on site.
I would be very curious to see a time study of how much time Washington teachers invest beyond the hours worked on site. For me personally, it does ebb and flow. I deliberately plan the scope of homework (read: major student writing I give feedback on) based on my family's evening and weekend schedules. Big essay weekends mean dad's working at the computer for 14 to 16 hours a day, plus several hours on the weekdays either side. That's the flow at highest tide--one weekend per month. The ebb is at least half an hour to an hour each evening--usually planning, replying to parent emails and phone calls, reviewing shorter assessments or organizing for the next day. It is rare to spend fewer than two hours per weekend day on something school related.
And to be clear: I am not complaining about the time--I know that putting in long hours is part of being in a profession as opposed to the alternative. My wife and kids might have a different opinion, but I try to keep some semblance of balance...My "three months' vacation" which is actually really only "most of July" makes up for some of it.
The other time study I'd like to see: what would happen to student learning if teachers worked the same number of hours but served only half the number of students?
