The muscles of the hand are divided into power muscles and precision muscles. The precision muscles (needed for writing) work better when the wrist is extended. Notice students who write with their wrist bent. They are probably experiencing muscle fatigue. Writing on a slanted surface is a good solution. Architects and artists often use an inclined surface. There are slanted clipboards that provide this function, but let's think along the lines of reinvention and reuse. Any 3-4 inch three ring binder makes a great slanted surface for a student's desk.
