When using outside sources in their writing, students must learn to balance efficiency with effectiveness. In other words, they must express themselves clearly and quickly, providing readers with enough explicit information to create a causal chain based on reasonable inferences. Yet they must guard against being overly explicit, boring their readers with too obvious causal connections. By using their own prior knowledge and experience to reshape the source material, writers can introduce new information and arouse the readers' interest. Students must realize that they can only fulfill their own intentions as writers by satisfying their readers' needs. (MM)
