Congratulations to Mirah J. Dow, Jacqueline McMahon Lakin, and Stephen C. Court on their Kansas school library impact study titled School Librarian Staffing Levels and Student Achievement as Represented in 2006–2009 Kansas Annual Yearly Progress Data. It was published in School Library Research, the AASL online journal, back in August 2012 and just came to my attention. I believe it’s the first such study to use annual yearly progress (AYP) data–a significant landmark in this body of research.
I first became aware of Keith Curry Lance's research while working on the 21st Century Information Fluency Project in Illinois. His comprehensive series of impact studies span a decade and provide detailed insight into the positive effects on learning that occur when schools build library media centers staffed with professional librarians. Anyone fighting to preserve their library media center should use this research to PROVE that the Library Media approach is more effective than almost any way of teaching. You want better test scores? More engaged students? Better prepared young people able to function in the 21st Century? Then build a library program as the heart of your ed-tech integration solution.
His research is so complete and conclusive I'm amazed anyone who says they rely on research to make decisons could dream of shuttering libraries. (And yet they do!) ~ Dennis
