“…Since the original implementation of the prescriptive ELD mandates required by Arizona House Bill 2064 (e.g., four hours of daily skill-based English instruction) in the 2008-2009 school year, existing studies emphasize the programmatic issues related to policy implementation and resulting achievement of ELs (deJong, Arias, & Sánchez, 2010), including the (a) lack of research base (August, Goldenberg, & Rueda, 2010;Krashen, Rolstad, & MacSwan, 2007), (b) overemphasis on prescription (Iddings, Combs, & Moll, 2012), (c) segregation of ELs away from mainstream peers (Gándara & Orfield, 2010), (d) dearth of content-area instruction (Gándara & Orfield, 2010, Martinez-Wenzl, Pérez & Gándara, 2010Ríos-Aguilar, González-Canche & Moll, 2010a), (e) heavy focus on skill-based grammar instruction (Combs, 2012), and (f) reliance on an invalid language test (Florez, 2010;García, Lawton, & deFigueiredo, 2010). In addition, researchers utilize standardized test data to demonstrate the lack of growth in EL achievement since the shift to ELD classroom instruction (García et al, 2010;Mahoney, MacSwan, Haladyna, & García, 2010).…”
