The document discusses principles for constructing an effective syllabus. An effective syllabus should make both a promise and a plan. The syllabus serves as a contract that clearly outlines expectations and obligations for both students and instructors. It also provides a plan by explaining course goals and how materials and activities are organized to help students achieve those goals. Developing a plan requires careful consideration of students and course purpose. A well-designed plan allows instructors to keep promises while maintaining flexibility.
