The question "why so much writing?" can be answered in three basic ways:
1. Writing promotes clear thinking.
2. Writing promotes effective and long-term retention of what has been learned.
3. Writing provides individuals and groups in a complex world with a voice and a record.
Students need to understand that writing is the single most powerful tool for thinking, learning and participating in the broad culture of a society.
