“…In addition, parents' educational and socioeconomic backgrounds (Blair and Qian 1998;Chen and Stevenson 1995) and their expectations, standards, satisfaction, and support (Cai 2003;Hess et al 1987;Huntsinger et al 2000;Stevenson et al 1990;Zhao and Singh 2011) also make a difference in children's mathematics achievement. Moreover, the examination-and achievement-orientation in the education system (Leung 1998;Wong et al 2012;Zhao et al 2006), curriculum and textbook contents (Brenner et al 1999;Park and Leung 2006;Stigler et al 1982;Zhao and Singh 2011), as well as the use of repetitive learning and the synthesis of memorisation and understanding (Leung 1999(Leung , 2001Wong et al 2012) all come to shape students' mathematics achievement. In brief, empirical work often attributes mathematics achievement gap to students' commitment and cognition, parents' values and investment, teachers' strategies and knowledge, and educational system and curriculum.…”
