Hi Rebecca. Sorry it took so long to reply. The librarian at Jackson Independent Schools is using robots as part of her classes and for family nights. Also, as part of problem based learning, students often need to do research. Learning to use library resources to select, find, and use appropriate materials and also learning and applying speaking, communication, and listening skills is important. I think the library would be a critical part of PBL and the librarian/meadia specialist should have time to plan with teachers as they determine the problems they will their students solve.
