This is the fourth in a series of five posts about online project-based learning (PBL) resources. If you are new to PBL I suggest taking the time to visit Post One and the site recommended there. That site really offers a comprehensive look at PBL. However, if you are familiar PBL, you can certainly start here or with Post Two or Post Three.
West Virginia Department of Education Teach21 PBL is a great website that offers lots of resources for PBL and reaches all the way up to the high school level. The landing page lets you search by subject (English Language Arts, Math, Science, Social Studies, Dance, Visual Arts, Theater, and Music) and grade level. Not every subject is covered for every grade but they do offer a full range of K-12 options. It may not look fancy but it is packed with useful information. I think this resource is especially helpful for middle and high school teachers.
