Impact of Changing Difficulty on Inferences From the National Assessment of Educational Progress

The U.S. Department of Education measures student achievement through the National Assessment of Educational Progress (NAEP). NAEP estimates of population proficiency quantiles are based on a Bayesian multiple-imputation procedure. This article shows (a) that the resulting estimates depend directly on the mix of item difficulties on the test, and (b) the difficulty of items on the NAEP mathematics exam has increased over time. Does the increasing difficulty of the exam lead to observable changes in student performance over time? This study compared the simulated performance of 1990 examinees on the easier 1990 exam and the more difficult 1996 exam. No significant differences were found. While our results instill confidence that these changes have not impacted the NAEP trend line, our findings are both data-specific and limited in scope, and NAEP should carefully evaluate future adjustments to the test in this manner.     

Children using Facebook: teachers’ discursive constructions of childhood

Conceptualizations of childhood are powerful determinants of adults’ interactions with children, and technology and social networking systems are affecting the nature of teachers’ knowledge of childhood. We analyzed questionnaire responses from 57 elementary-level teachers from Quebec regarding children’s use of Facebook. Through discourse analyses, we found four common images of childhood (child as innocent, evil, future adult, and agent) present in the teachers’ responses; however, the context of social media brought to fore questions about adult surveillance at a time of generational pliability and teachers’ self-understanding in relation to their knowledge of children.     

Near-point Gripping in Pencil Hold as a Possible Disabling Factor in Children with SEN

Stephanie Thomas, Head of Learning Support at Heathfield School, Kidderminster, considers the effects of near-point gripping, in pen or pencil hold, on the overall educational performance of children with specific learning difficulties (SpLD).     

AfterMath: the work of proof in the age of human-machine collaboration

During the 1970s and 1980s, a team of Automated Theorem Proving researchers at the Argonne National Laboratory near Chicago developed the Automated Reasoning Assistant, or AURA, to assist human users in the search for mathematical proofs. The resulting hybrid humans+AURA system developed the capacity to make novel contributions to pure mathematics by very untraditional means. This essay traces how these unconventional contributions were made and made possible through negotiations between the humans and the AURA at Argonne and the transformation in mathematical intuition they produced. At play in these negotiations were experimental practices, nonhumans, and nonmathematical modes of knowing. This story invites an earnest engagement between historians of mathematics and scholars in the history of science and science studies interested in experimental practice, material culture, and the roles of nonhumans in knowledge making.     

“I've Never Heard of It Before”: Awareness of Open Access at a Small Liberal Arts University

Small colleges and universities, often late adopters of institutional repositories and open access initiatives, face challenges that have not fully been explored in the professional literature. In an effort to gauge the level of awareness of open access and institutional repositories at the University of Wisconsin–Eau Claire (UWEC), the authors of this article surveyed fellow faculty members at this small liberal arts university before the 2011 Open Access Week. The survey results reveal that faculty members at UWEC do not share the same level of awareness concerning open access and institutional repositories that was found in the existing scholarly literature.
