“…Several researchers have compared grammar descriptions that are presented in textbooks with real world language use (Al-Wossabi, 2014;Barbieri and Eckhardt, 2007;Biber and Reppen, 2002;Carter, 1998;Eckhardt, 2001;Frazier, 2003;Gilmore, 2004;Khojasteh &Shakrpour, 2014;Šegedin, 2008) and, all have noted that there is a large gap between the explanations and descriptions in textbooks and real world language use. They attribute this to several factors: 1) textbook material is not taken from empirical data about language use but rely on writer's intuition; 2) textbooks present grammatical constructions as equally generalizable and of equal communicative importance; 3) information concerning pragmatics, discourse context and register is ignored; 4) textbooks are based on written norms; 5) textbooks simplify the grammar for pedagogical purposes (Barbieri and Eckhardt, 2007;Biber and Reppen, 2002;Carter and McCarthy, 1995;Lawson, 2001).…”
