In this longitudinal study, we examined the relationship between primary grade (K-2) Spanish and English language- and word-based skills and later English reading comprehension (RC) outcomes (Grades 5 and 8) among children (n = 148) from immigrant, Spanish-speaking, low-income homes in English instructional contexts since kindergarten entry. As…

This study tested three hypotheses about the direct and indirect contributions of derivational morphological awareness to English reading comprehension in sixth-grade students from differing language backgrounds (n= 952). Students included Spanish-speaking, Filipino-speaking, and Vietnamese-speaking language minority learners as well as native…

A study was conducted in a large Head Start organization that serves large numbers of Latino children in order to empirically describe the nature and quality of the classroom language learning environment. By observing 147 literacy-based lessons in 6 classrooms and surveying 167 teachers throughout the organization, we investigated the amount of…

This study examined teachers' language use across the school year in 6th grade urban middle-school classrooms (n = 24) and investigated the influence of this classroom-based linguistic input on the reading comprehension skills of the students (n = 851; 599 language minority learners and 252 English-only) in the participating classrooms. Analysis…

Despite acknowledgement of the limited English vocabularies demonstrated by many language minority (LM) learners, few studies have identified skills that relate to variation in vocabulary growth in this population. This study investigated the concurrent development of morphological awareness (i.e., students' understanding of complex words as…

Connectives (e.g., although, meanwhile) carry abstract meanings and often signal key relationships between text ideas. This study explored whether understanding of connectives represents a unique domain of vocabulary knowledge that provides special leverage for reading comprehension, and whether the contribution of knowledge of connectives to…

This longitudinal study modeled growth rates, from ages 4.5 to 11, in English and Spanish oral language and word reading skills among 173 Spanish-speaking children from low-income households. Individual growth modeling was employed using scores from standardized measures of word reading, expressive vocabulary, and verbal short-term language…

This longitudinal study examined the process of English reading comprehension at age 11 years for 173 low-achieving Spanish-speaking children. The influence of growth rates, from early childhood (age 4.5 years) to pre-adolescence (age 11 years), in vocabulary and word reading skills on this complex process were evaluated with structural equation…

This study examined the relationship between morphological awareness and reading comprehension in English among Spanish-speaking English language learners (ELLs) followed from fourth through fifth grade. Students' ability to decompose derived words while reading was assessed using an experimental task. Multiple regression analyses were used to…

This study explores factors influencing the degree to which language minority (LM) children from Spanish-dominant homes understand how connectives, such as "in contrast" and "because", signal relationships between text propositions. Standardized tasks of vocabulary, listening comprehension, word reading, and a researcher-designed text cohesion…
