Homework should be broadly defined. It is not confined to academic tasks related to classroom work.
Homework is also an opportunity for personal reflection on the meaning, significance, or symbolism of a recent experience/event such as college orientation.
Orientation "homework" can focus admonishing students to work on a list of benefits they will receive from their graduation, how their daily routine will be amended to foster academic success, how family and friends see you now and how that perception will gradually change as you move toward graduation.
Orientation Homework is the school's opportunity to encourage students to "Think Outside the Classroom Box."
