In order to meet the needs of today's knowledge economy, education needs to move beyond the industrial age approach of treating all learners as if they are the same and adopt a learner-centered model of education suitable for the information age. To support this model, a new and transformative technology is needed that focuses on mastery and customized learning. This article reviews the existing approaches to educational technology before proposing a new, customizable, open, and interoperable technology: a personalized integrated educational system (PIES) that provides full functionality for students, teachers, parents and other stakeholders and bridges the gaps between formal and informal learning. PIES' four primary functions: record keeping, planning, instruction, and assessment, as well as secondary functions, are defined and described. Future challenges and research opportunities are also identified.
