We explore the potential of a computer-adaptive decoding game in Spanish to increase the decoding skills and oral reading fluency in Spanish and English of bilingual students. Participants were 78 first-grade Spanish-speaking students attending bilingual programs in five classrooms in Texas. Classrooms were randomly assigned to the treatment…

This study compares the academic achievement of 288 Hispanic students enrolled in the content-based English as a second language program and the late exit transitional bilingual program in an urban elementary school in Texas. The goal was to determine if the two programs had differing effects on Hispanic student achievement in reading. The sample…

The purpose of this study was to test the efficacy of a Tier 2 standard protocol supplemental intervention designed simultaneously to develop root word vocabulary and reinforce decoding skills being taught to all students in the core beginning reading program with kindergarten Spanish-speaking English learners (ELs). Participating students were…

This article reports the outcomes of a multiyear study comparing the English and Spanish language and reading performance of Spanish-dominant children randomly assigned, beginning in kindergarten, to transitional bilingual education (TBE) or structured English immersion (SEI) for periods of up to 5 years. On the Peabody Picture Vocabulary Test and…

This paper reports the fifth-year results of a study comparing the English and Spanish language and reading performance of Spanish-dominant children randomly assigned beginning in kindergarten to Transitional Bilingual Education (TBE) or Structured English Immersion (SEI). This is the first randomized study to compare TBE and SEI reading…

This study investigated the effects of three instructional conditions on precursors to successful reading for Spanish-speaking English language learners (ELL). The study was conducted using a randomized, alternate treatment control group design specifically targeting phonological awareness (PA) listening comprehension (LC), and decoding in a…

Two studies of Grade 1 reading interventions for English-language (EL) learners at risk for reading problems were conducted. Two samples of EL students were randomly assigned to a treatment or untreated comparison group on the basis of their language of instruction for core reading (i.e., Spanish or English). In all, 91 students completed the…
