1. Real-world relevance: Activities match as nearly as possible the real-world tasks of professionals in practice rather than decontextualized or classroom-based tasks.
   
2. Ill-defined: Activities require students to define the tasks and subtasks needed to complete the activity.
   
3. Complex, sustained tasks: Activities are completed in days, weeks, and months rather than minutes or hours. They require significant investment of time and intellectual resources.
   
4. Multiple perspectives: Provides the opportunity for students to examine the task from different perspectives using a variety of resources, and separate relevant from irrelevant information.
   
5. Collaborative: Collaboration is integral and required for task completion.
   
6. Value laden: Provide the opportunity to reflect and involve students’ beliefs and values.
   
7. Interdisciplinary: Activities encourage interdisciplinary perspectives and enable learners to play diverse roles and build expertise that is applicable beyond a single well-defined field or domain.
   
8. Authentically assessed: Assessment is seamlessly integrated with learning in a manner that reflects how quality is judged in the real world.
   
9. Authentic products: Authentic activities create polished products valuable in their own right rather than as preparation for something else.
   
10. Multiple possible outcomes: Activities allow a range and diversity of outcomes open to multiple solutions of an original nature, rather than a single correct response obtained by the application of predefined rules and procedures.
