Because of standards-based grading and switching from lunch duty to tardy duty this year, I have been able to help a lot of students on math at lunchtime and after school. However, lunch is only 20 minutes and many students have after-school jobs or sports. I saw this article on a common study hall for students *and* teachers on the ASCD SmartBrief from a few weeks ago and thought it would be great for my school. We have an advisory period at the end of the day, but not all students and teachers are free at the same time. For example, if I advise 11th grade, my 12th grade math students would not be able to get help from me if I am doing an activity on job shadowing rather than holding study hall. A common mid-day non-lunch block would also provide in-school time for IB-specific activities such as the Extended Essay or Internal Assessments. I realize that it does take away a planning period, but investing this time up front could save a lot of planning time later on.
