Each course has its own Course Outcomes that should be addressed in your PLA Portfolio.
Each component (resumes, documentation, and narrative) can work together to address the Course Outcomes.
You will need to write a separate Educational Narrative for each course you’re challenging. You do not need separate PLA resumes for each course (just one will suffice).
Study the terminology and language used in the Course Outcomes to incorporate that into your Portfolio.
You may need to do a little research to fill in some gaps in your knowledge about terminology or academic philosophy mentioned in the Course Outcomes.
Sometimes reading the course textbooks or reading articles online can bolster your Educational Narrative and/or give you confidence that you know the material as you begin to create your Portfolio.
