CREATE 2009 10/5/09 Empirical and Theoretical Background: Considerable previous work (García, 1991; Nagy, TESTING THE EFFICACY OF 1997; National Reading Panel, 2000; Verhoeven, 1990) suggests that one major determinant of poor A COGNATE CURRICULUM reading comprehension, for Latino children and for other lagging readers, is low vocabulary. Lack of knowledge of the middle and lower Maria Carlo, University of Miami frequency 'academic' words encountered in Diane August, Center for Applied Linguistics middle and secondary school texts impedes comprehension of those texts, which in turn Chris Barr, University of Houston impedes the natural process of learning new Ana Pazos-Rego, St. Thomas University word meanings from exposure during reading (Stanovich, 1986). Austin, CREATE Conference, October 5-6, 2009 Continued… Research Questions One strategy believed to be successful in promoting the rapid acquisition of vocabulary by ELLs involves Can an intervention developed to teach teaching children about the morphological structure of cognate awareness to Spanish/English words. bilingual 3rd and 5th graders improve their Researchers believe that it is beneficial for ELLs if instruction on the structural analysis of words includes learning of English words that have cognate making students aware of the cross-linguistic status in Spanish? morphological relationships between words in their two languages (García & Nagy, 1993; Nagy, García, Does the cognate recognition strategy transfer Durgunoglu, & Hancin-Bhatt,1993; Jiménez et al., 1996; to other cognates that have not been Nation 2001). instructed? This involves making students aware of words that are cognates (words that are spelt alike and have similar meanings in two languages), and making them aware of similarities between derivational morphemes in the two languages (e.g, motivación-motivation).
