On PBLU.org, teachers can dive into project based learning by selecting a project, and by taking free online courses to learn how to use project based learning in the classroom. As of this writing, there are 20 projects and the course master is on sabbatical.
Each project includes its estimated duration, target grade levels, content area subjects, common core standards, an overview and work samples. The courses include How to Manage the Project, How to Assess the Project, How to Showcase Student Work, How to Launch the Project, How to Create a Project Calendar, and How to Get PBL Teacher Certification.
