As you look back over a school year, you'll note room for celebration and room for revision. That's typical.
It's good to refrain from analysis the final weeks of school, and then when you're rested, do a great big analysis of the year. After that you can set next year's agenda.
Look for the promise in the problems that occurred and make change in those areas. Also celebrate all the good work that happened throughout the year--well meaning educators everywhere are doing a great job by students, and it's important that they don't forget that.
