“…Further, the vision and changes to the standards "cannot be realized unless the standards permeate the education system and guide curriculum, instruction, teacher preparation and professional development and student assessment" (National Research Council, 2012, p. 241). Researchers have investigated differences in cross-national performance from several perspectives including teacher quality, curriculum, and academic learning time (Merry, 2013). Not surprisingly, students with high-quality teachers and countries with centralized curricula have students with stronger academic performance (Fuchs & Woessmann, 2007;Gordon, Kane, & Staiger, 2006;Hanushek, 2011) while the effects of increased academic learning time appear linked to the quality of that learning time (Baker, Fabrega, Galindo, & Mishook, 2004;Silva, 2007) suggesting that quantity at the expense of quality is problematic.…”
