Elementary teachers need to be equipped with STEM content knowledge. Only 30% of elementary education programs at
the undergraduate level require pre-service teachers to take a science course (Greenberg, McKee, & Walsh, 2013). Graduatelevel
elementary teacher education programs do not fare much better; 56% of such programs do not require candidates to
have taken a science course at the graduate level (Greenberg et al., 2013). Science and mathematics are clearly subjects that
elementary school teachers must teach, but the extent to which they master these subjects is largely limited by the exposure
they have had to these content areas. Thus, many elementary teachers simply teach what they remember from science classes
they took when in K-12 schooling (Nadelson et al., 2013). Furthermore, the methods they use to teach the content largely
