This is the final 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, Post Three or Post Four.
CIESE is a stellar website that offers lots of resources for STEM (Science, Technology, Engineering, and Mathematics) PBL. The landing page lets you search by subject: Science (Life, Earth, Physical, or Environmental), Technology (Real Time Data, Online Collaboration, Primary Sources, or Robotics), Engineering (Systems, Civil, Mechanical, Electrical, or General), Mathematics
(Numbers & Operations, Algebra, Geometry, Trigonometry, or Data Analysis) and links to other resource archives. If you are looking for a STEM PBL this a great place to check out for premade options and ideas of how to model your own creation.
