Technology has become increasingly prevalent in early care and education settings, yet little is known about the effectiveness, function, and requirements for technologies that are available to early childhood programs. The purpose of this project was to review the knowledge base related to the use of technology to support the practice of early childhood practitioners who work directly with children and families. The review was conducted by NORC at the University of Chicago. The review examined uses of technology among four Topic Areas. The first three Topic Areas focused on early childhood practitioners' use of technology to support 1) instruction and assessment, 2) parent, family and community engagement (PFCE), and 3) professional development and informal learning. The fourth Topic Area outlined barriers to and facilitators of practitioners' effective use of technology to support early childhood practice. NORC employed three methods to complete the review: a bottom-up web search to obtain a broad sampling of both common and cutting-edge uses of technology; a top-down search of academic databases to assess the evidence-base for the technologies; and interviews with experts who have built, used, or evaluated these technologies.
