“…Next, specific policy and practice shifts related to both formal and informal science learning may also mitigate income-based science achievement gaps. For example, attention might be given to the time spent on science (Bassok et al, 2016;Blank, 2013;Marx & Harris, 2006;Phillips, Gormley, & Lowenstein, 2009;Sackes, Trundle, & Bell, 2013;Sackes, Trundle, Bell, & O'Connell, 2011;Tu, 2006), the capacity of teachers and school leaders to teach science (Bianchini, Dwyer, Brenner, & Wearly, 2015), and the ways in which science is taught and integrated with other subjects (Hayes & Trexler, 2016). The recently developed Next Generation Science Standards and the National Research Council's corresponding framework on K-12 science instruction provide some grounding for such shifts in instructional practice around science.…”
