Ed Psyc Central a personal effort of Heidi Weiman, of Kendall College. The site aims to identify resources in Educational Psychology and related areas for those interested in teaching and learning across the lifespan. Links are arranged by both topic (e.g. Adult Learning, Higher Ed., Professional Development) and category (e.g. Organizations, Engines, Theory-Research-Practice). The links themselves are just listings, no descriptive information.
School Psychology Resources Online is a great specialized source. Well organized and limited in scope it is easy to use and most pointers lead to substantial information. Includes brief treatises on the most common school problems and links to other professional contacts.
Center for Psychology in Schools and Education is affiliated with the American Psychological Association. The page offers a few full text papers on topics of wide interest such as violence in schools and coping with disaster.
