"11 Principles of Effective Character Ed" contains articles, blog, lesson plans, and more. I like the great early childhood activities (under Lesson Plans tab), such as Social Skills Role Playing where children act out different conflict-scenarios and cooperatively discuss solutions.
I love this site for its free resources. You can print full-size character ed posters for your classroom and award certificates to recognize positive student behavior (sportsmanship, fairness, confidence, kindness,etc). There are also great stories and lesson plans that highlight virtues. You may need to modify any religious references, but still worth it!
The journal is a forum for research reports, theoretical discussion, practical application, intellectual challenge, and scholarly reflection, as well as book reviews and other resource evaluations. I like the article "Effects of a School Based Program to Improve Adaptive School Behavior," by Kort C Prince. Specifically, I use aspects of the Life Skills Program outlined here. Identifying goals and using objectives 1-3 is a great guide for developing positive intra and inter-personal skills.
This section contains articles and resources about character education that are designed for parents and other community members. "The Value of a Real Apology," by Dr Richard Curwin, deals with teaching and modeling the language of meaningful apologies and following through with kind actions. This is a great way to encourage empathy in the early grades.
Blog by educators, for educators, including videos, to disperse ideas of character education. I particularly like the info on "The Value of An Apology" and "Motivated vs. Unmotivated." In the latter post, students can video chat with older, highly motivated students that can serve as positive peer role models.
