TCEA recently published an article in their TechEdge Magazine which discussed some good open educational resources. OER are a great way to maximize the use of FREE online tools and information - super important at a time when budgets are slowly dwindling away to nothing. Most of these resources also carry creative commons licenses, not traditional all rights reserved licenses, which allows you to modify and redistribute their materials legally. Here are some of the sites highlighted by TCEA and some of my personal favorites...
FreeReading - reading intervention program for PK-6
Teachers' Domain - videos, interactives, lesson plans
Curriki - all subjects, grades K-12
Kids Open Dictionary Builder - free, open, sharable dictionary for kids
OER Commons - excellent collection of OER sites
Learn NC - lesson plans, professional development and web resources
What OER sites/programs are you using?
