The Professional Learning Board toolbar is a browser add-on designed with teachers and librarians in mind. The PBL toolbar provides a selection of tools that can help teachers quickly locate lesson plans and other educational resources hand picked by PBL. The toolbar also helps you quickly find grant resources and professional development resources.
I installed the PBL toolbar and tried it for a while. Many of the resources that found in the PBL toolbar had an elementary school and middle school focus. I prefer a clutter-free toolbar so the PBL toolbar didn’t appeal to my visual senses. That said, it is very easy to use and I can see it being a great toolbar for some teachers.
