Benefits include increased self-confidence, motivation and a sense of personal agency for the learners. Benefits for teachers include a deeper understanding of individual learners’ needs and progress. Different types of portfolios are explained, including both paper-based and electronic options, along with typical component elements. Challenges of using portfolios with ELL learners are explored.
