A student portfolio is a collection of a student's work that showcases their skills, achievements, and progress over time. It can include various materials such as essays, projects, artwork, and test scores. Portfolios are often used in educational settings to assess a student's learning and development. These portfolios can be physical or digital and are typically organized to highlight a student's strengths and areas for improvement. They serve as a valuable tool for both students and teachers, allowing for reflection on learning experiences and providing a comprehensive view of a student's capabilities.
