This brief describes how technology may directly support early childhood practitioners' "formal" professional development (e.g., through in-service programs or training on product-specific implementation and enrichment) and informal learning (e.g., independent learning and peer collaboration) for practitioners (Topic Area 3). In addition, the brief describes barriers to and facilitators of practitioners' effective use of technology to support early childhood practice. This brief is purely descriptive of the technologies that are currently available and makes no recommendations or endorsements of individual technologies, products, or programs. (author abstract)
