A portfolio is a collection of a student's work that shows their learning process and improvements over time. It can include documents, drawings, photos, and certificates. There are different types of portfolios like work portfolios that highlight developments, process portfolios that document the stages of learning, and product or showcase portfolios that feature the best work. Creating an effective portfolio involves planning, collecting, selecting, reflecting on entries, and connecting them to show one's learning. An e-portfolio is an electronic version of a portfolio.
