“…Previous research finds that teacher librarians do not feel confident in their content knowledge of STEM areas (Mardis, 2007;Perrault, 2007;Rawson, 2014;Rawson, Anderson, & Hughes-Hassell, 2015;Subramaniam & Edwards, 2014;Subramaniam et al, 2012;Subramaniam et al, 2013). Some attribute this to the fact that many teacher librarians come from a humanities background and lack the content knowledge in the STEM areas and are therefore hesitant to collaborate with teachers in these areas (Mardis, 2007;Perrault, 2007;Schultz-Jones, 2010;Schultz-Jones & Ledbetter, 2009Young, 2013). This lack of familiarity with the STEM areas and content standards can also lead to an inadequate collection of resources -both print and nonprint to support STEM education (Hoffman & Mardis, 2008;Mardis, 2014;Mardis, 2015;Schultz-Jones, 2010;Shultz-Jones & Ledbetter, 2009;Young, 2013).…”
