Digital portfolios can promote learning for both students and teachers by allowing students to showcase their work and progress over time. This presentation analyzes digital portfolios through a systems approach to understand how they support student assessment and success. Key parts of the system that interact include students, teachers, school policies, and technology resources. Changes to these parts, such as limiting access to portfolios, can impact the system. Ultimately, digital portfolios engage students and provide authentic assessment of student learning and achievement.
