Many students will benefit from a degree of preplanned structure and habit when it comes to study space. Here are some thoughts to consider when creating a study space for your student.
General Principle: Focus on what you want to accomplish, not how you want things to look.
Start your thinking from the end of the school day. Consider the "Drop Zone" and the "Pickup Zone" problem:
Through which door does the student enter? Does s/he have a place here to leave coats, shoes, skateboard, etc.? Is this also where the backpack gets dropped? Where would you like the backpack to be when it comes time to start homework?
