We highlight some important deficiencies in existing alignment systems and formulate suggestions for improved future ones. We consider how the changing substance of newer educational standards, a multi-faceted view of standard alignment, and a more nuanced view of the ‘alignment’ concept may bring the long-sought goal of automated standard alignment closer. We explore how lexical similarity of documents, a World+Method representation of semantics, and network-based analysis can yield promising results. We furthermore investigate the nature of false positives to better understand how validity of match is evaluated so as to better focus future alignment system development.10aAccounting10aBIS1 aMarshall, Byron1 aReitsma, Reindert1 aSamson, Carleigh  u/biblio/unraveling-k-12-standard-alignment-report-new-attempt01555nas a2200157   4500008004100000245010500041210006900146260000900215520095300224653000801177100002201185700002101207700001701228700002401245856012801269       2015                        eng d00aThe Relevance of K-12 Engineering Curricula to NGSS: an Analysis of TeachEngineering-NGSS Alignments0 aRelevance of K12 Engineering Curricula to NGSS an Analysis of Te  c20153 aThe 2013 publication of the Next Generation Science Standards (NGSS) provided the first widely adopted set of science standards to include engineering design throughout all K-12 grades. In doing so, NGSS raised the relevance of the K-12 engineering education sector on a national scale. The TeachEngineering digital library, representative of the K-12 engineering education sector through its collaboration of 36, mostly NSF-funded, K-12 engineering education programs across the US, recently aligned its 1,300+ K-12 engineering lessons and hands-on activities to the NGSS. This paper provides analysis of both the alignment process and its results. As such, we offer insight into the correspondence between the NGSS and a broad, collection of K-12 engineering learning objects and hence, into the mutual relevance of K-12 engineering curriculum and the NGSS. We also provide some recommendations for future K-12 engineering curriculum development.10aBIS1 aReitsma, Reindert1 aSamson, Carleigh1 aSoltys, Mike1 aSullivan, Jacquelyn  u/biblio/relevance-k-12-engineering-curricula-ngss-analysis-teachengineering-ngss-alignments00626nas a2200145   4500008004100000245012900041210006900170260002200239653000800261100002200269700002000291700001800311700002100329856013000350       2015                        eng d00aWorkshop: TeachEngineering Digital Library: Hundreds of Free, Searchable, NGSS-aligned Hands-on Engineering Lessons for K-120 aWorkshop TeachEngineering Digital Library Hundreds of Free Searc  aSeattle, WAc201510aBIS1 aReitsma, Reindert1 aZarske, Malinda1 aYowell, Janet1 aSamson, Carleigh  u/biblio/workshop-teachengineering-digital-library-hundreds-free-searchable-ngss-aligned-hands
