This document discusses using student portfolios as a learning, monitoring, and assessment tool. It aims to encourage cognitive development and meaningful learning experiences. Portfolios are a collection of student work that show effort, progress, and achievements. They are made in folders containing dated work that allow judging improvements. Students keep portfolio works and self-assess with teacher input. Portfolios support a constructivist view of active learning and help students rethink works by improving papers. They integrate diverse experiences and encourage self-reflection to authentically assess learning.
