Final answer:
A portfolio is a collection of work demonstrating a student's skills and accomplishments, often used in writing courses to assess growth and assign grades.
Step-by-step explanation:
The collection that consists of a systematic and organized collection of a student's work, demonstrating their skills and accomplishments, is known as a portfolio. It is a compilation of academic and professional documents, samples of writing, or creative works, depending on the field of study. In an educational setting, a portfolio can be used to show a student's growth and achievements, particularly in a writing course.
A writing portfolio may consist of various drafts of a student's writing, finalized pieces, and may include a reflection on the writing process and development over the semester. Instructors may use the portfolio to assess a student's performance and even assign grades. A portfolio showcases not only the end result but the progression and improvement in the student's work.
