The US Department of Education’s Institute of Education Sciences (IES) supported the National Center of Education Research (NCER) as it commissioned the development of this compendium with the intent to present funded research project information in a structured, accessible, and usable manner. This compendium organizes information on the education technology projects sponsored by NCER and NCSER into three main sections: Technology to Support Student Learning (in which the target of the project was students themselves or their families), Technology to Support Teachers and Instructional Practice, and Technology to Support Research and School Improvement. Within each section, projects are sorted into chapters based on content area, grade level, and intended outcome. In determining the chapters, we considered the National Education Technology Plan (U.S. Department of Education, Office of Educational Technology 2010, 2016). The compendium also includes multiple appendices and an index to help readers locate specific types of information (e.g., projects that focus on virtual environments, game-based technologies, etc.).
