Its inquiry-based lessons and hands-on activities use real-life engineering as a vehicle for the integration of science and math in P-12 classrooms. Mapped to educational content standards, the activities are age-appropriate, inexpensive to conduct, and relevant to students’ daily lives, helping science and math come alive. The collection is a powerful resource for those in P-12 or higher education, industry and professional communities wanting to improve STEM literacy, to engage young students in the joys and creativity of engineering and the design process, and to increase the number of students pursuing STEM careers.<br>This paper investigates TeachEngineering usage trends and curricular submission statistics. Specifically, we analyze the submission process for curriculum contributed from external authors, suggest practices for submitting new curriculum, and discuss possible support avenues for future submissions.10aBIS1 aReitsma, Reindert1 aZarske, M.1 aSullivan, J.1 aKlenk, P.1 aForbes, M.1 aCarlson, D.  u/biblio/teachengineering-digital-library-improving-access-p-12-engineering-conversation-002129nas a2200157   4500008004100000245013300041210006900174260002500243520149400268653000801762100002201770700001401792700001501806700001701821856013301838       2010                        eng d00aAre French Fries and Grades Bad for You?  Conflicting Evidence on how K-12 Teachers Search in a K-12 Engineering Digital Library0 aAre French Fries and Grades Bad for You Conflicting Evidence on   aLouisville, KYc20103 aThe TeachEngineering digital library provides teacher-tested, standards-based engineering content for K-12 teachers to use in science and math classrooms. Since its release in 2005, it has demonstrated significant growth in users and in contributors; data on this growth is presented. The TeachEngineering team continues to research its search functions and user interface in order to ensure that it is meeting the needs of its intended users, K-12 teachers. Empirical evidence of an experimental study on the dimensions of alignment between digital K-12 lesson materials and education standards, however, contradicts that of the observed search behavior of patrons of TeachEngineering. Whereas the experiment convincingly shows that grade band information does not add to the teaching materials’ relevance for an educational standard, observed patrons’ searching patterns show ample evidence of grade band-based searches. In this paper we offer that although grade band-based searches should perhaps be avoided because they improperly bias search results, they are such a prominent feature in the actual use of the digital library that as designers we must support them while mitigating the risk of unfortunate search bias. As a possible solution we suggest supporting grade-based searches yet offering query expansion by widening the grade band. These results also imply that curriculum developers pay close attention to the assignment of grade bands to their lessons and activities.10aBIS1 aReitsma, Reindert1 aKlenk, P.1 aZarske, M.1 aSullivan, J.  u/biblio/are-french-fries-and-grades-bad-you-conflicting-evidence-how-k-12-teachers-search-k-12-000454nas a2200157   4500008004100000245004000041210003900081260000900120653000800129100002200137700001200159700001500171700001700186700001500203856007800218       2004                        eng d00aTeachengineering Resources for K-120 aTeachengineering Resources for K12  c200410aBIS1 aReitsma, Reindert1 aCyr, M.1 aMooney, M.1 aSullivan, J.1 aYbarra, G.  u/biblio/teachengineering-resources-k-12-000634nas a2200193   4500008004100000245007500041210006900116260000900185300001200194490000700206653000800213100001600221700002200237700002000259700001800279700001700297700001600314856011000330       2003                        eng d00aExploiting Engineering as a Unique Distance Learning Tool  19, 379-3880 aExploiting Engineering as a Unique Distance Learning Tool 19 379  c2003  a379-3880 v1910aBIS1 aCarlson, L.1 aReitsma, Reindert1 aBrandemuehl, M.1 aHertzberg, J.1 aSullivan, J.1 aGabbard, S.  u/biblio/exploiting-engineering-unique-distance-learning-tool-19-379-388-000459nas a2200181   4500008004100000245002400041210002200065260000900087300001000096490000700106653000800113100001700121700001600138700001700154700002000171700002200191856006400213       2000                        eng d00aA Living Laboratory0 aLiving Laboratory  c2000  a31-400 v8810aBIS1 aLightner, M.1 aCarlson, D.1 aSullivan, J.1 aBrandemuehl, M.1 aReitsma, Reindert  u/biblio/living-laboratory-0
