We present two evaluations of these tools; one is a comparative analysis of human vs. CAT standard assignment. Another is the use of a 24M-row database of SAT-based standard alignments. The latter explores the feasibility of standard cross walking10aBIS1 aReitsma, Reindert1 aDiekema, A.  u/biblio/educational-standard-assignment-some-recent-findings-working-nsdl-tools-cat-sat-001423nas a2200133   4500008004100000245008500041210006900126260001700195520090700212653000801119100002201127700001601149856012401165       2010                        eng d00aNetwork Visualization of Human and Machine-based Educational Standard Assignment0 aNetwork Visualization of Human and Machinebased Educational Stan  aLondonc20103 aRapid growth in the availability of digital libraries of K-12 curriculum, coupled with an increased emphasis on standard-based teaching has led to the development of automated standard assignment tools. To assess the performance of one of those tools and to gain insight into the differences between how human catalogers and automated tools conduct these standard assignments, we explore the use of network modeling and visualization techniques for comparing and contrasting the two. The results show significant differences between the human-based and machine-based network maps. Unlike the machine-based maps, the human-based assignment maps elegantly reflect the rationales and principles of the assignments; i.e., clusters of standards separate along lines of content and pedagogical principles. In addition, humans seem significantly more apt at assigning so-called ‘methodological’ standards.10aBIS1 aReitsma, Reindert1 aDiekema, A.  u/biblio/network-visualization-human-and-machine-based-educational-standard-assignment-0
