“…Central among these emergent literacy skills are the three areas of alphabet knowledge, phonological awareness, and oral language (Storch & Whitehurst, 2002; Whitehurst & Lonigan, 1998; Lonigan, Schatschneider, Westberg & the National Early Literacy Panel, 2008a). The robust and unique predictive validity of these three skill sets has been repeatedly demonstrated in a wide array of studies with varied assessment measures (Catts, Fey, Zhang, & Tomblin, 1999; deJong & van der Leij, 1999; Naslund & Schneider, 1996; Scarborough, 1989; 1998; Wagner, Torgesen, & Rashotte, 1994; Wagner et al, 1997), including both norm-referenced standardized assessments and researcher-developed measures. Further, there is increasing evidence that all three are causally related to decoding, spelling, or comprehension skill, perhaps especially when instruction combines a focus on more than one of these elements (Lonigan, Schatschneider, Westberg & the National Early Literacy Panel,2008b; Schneider, Roth, & Ennemoser, 2000; Share & Gur, 1999).…”
