Diane Oberg, Professor Emerita from the University of Alberta named her paper on a quote from from a British inspector for education (Ofsted), who described the work of a secondary school as being "relentlessly focused on learning". And that, stresses Oberg, is what the work of the school library learning commons should be all about. She is talking about the importance of evaluation, based on standards, to foster this work. The impact of the program needs to be measured through evidence-based practice.
