http://www.geoteach.org is a great website to teach students about geography.  This site includes three great lesson plan units to help broaden students vision of the world.  There is a pull-down menu for: Teachers Resources; Forums, Student Resources, Contact Information, and a Facilitator's Guide.  There's also a video overview and a video comments section for professional development. I plan on using the "Globalization Unit."  This unit compares China, Japan, Mongolia, North & South Korea, and Taiwan - economic, social/cultural, politcal, physical/environmental areas.  It's very easy to use with or without computer skills.  This is an excellent site!
