Few studies have considered academic vocabulary interventions for students who have learning disabilities (LD) and also are English learners (EL). This research explored the effects of the third year of the Creating Habits that Accelerate Academic Language of Students (CHAAOS) vocabulary intervention for eighth-grade students who received English…

English learners with learning disabilities (LD) have well-documented difficulties comprehending text. This study examined the effects of an intensive reading intervention (Reading Intervention for Adolescents [RIA]) on reading outcomes (word reading, vocabulary, and comprehension) for ninth-grade ELs with LD (n = 85). In the RIA, students…

As a growing number of students with learning disabilities (LD) receive science instruction in general education settings, students with LD continue to perform significantly lower than their non-disabled peers. The shift from textbook-driven instruction to inquiry-based approaches to science learning supports students who struggle with reading.…

This study investigated the effects of a combined contextual and morphemic analysis strategy to increase prediction and analysis of science vocabulary words by three high school (9th--10th grade) English language learners with reading disabilities. A multiple baseline across participants design was used. Students analyzed science words using the…

The present study seeks to evaluate a hybrid model of identification that incorporates response to instruction and intervention (RTI) as one of the key symptoms of reading disability. The 1-year stability of alternative operational definitions of reading disability was examined in a large-scale sample of students who were followed longitudinally…

We describe findings from a series of longitudinal studies utilizing a response to intervention framework implemented over 3 years with students in Grades 6 through 8 with reading disabilities and poor reading comprehension. Students were identified based on reading comprehension scores in Grade 5 (n = 1,083) and then randomized to treatment or…

This study examined the effects of three types of reading interventions on the science text reading of secondary students with learning disabilities (LD). Twenty 10th-grade students with LD participated in the study. Using a within-subjects design, the relative effects of three different instructional approaches--text reading, vocabulary learning,…

The study, involving 61 learning-disabled junior high students, compared the short-term and long-term effectiveness of definition instruction with interactive vocabulary strategies (semantic mapping, semantic feature analysis, and semantic/syntactic feature analysis). Students participating in the interactive strategies demonstrated greater…

The effects of vocabulary instruction on word knowledge and reading comprehension were investigated. Average students learned some word synonyms under all conditions except a noninstructional control condition. However, learning disabled students acquired fewer meanings across all conditions and seemed to require more direct instruction in order…
