Establishing validated science programs for students with or at risk for learning disabilities requires testing treatment effects and exploring differential response patterns. This study explored whether students' initial mathematics and reading skills influenced their treatment response to a whole-class, second-grade science program called…

We examined the efficacy of a content acquisition and reading comprehension intervention implemented in eighth-grade social studies classrooms. Using a within-teacher randomized control design, 18 eighth-grade teachers' social studies classes were randomly assigned to a treatment or comparison condition. Teachers taught all their classes…

Teachers' implementation of differentiated supplemental instruction is critical to help students with or at risk for reading-related disabilities acquire early reading and vocabulary skills. This study represents an initial investigation of whether classroom teachers' intervention fidelity (exposure, adherence, and quality) of targeted reading…

In this multi-year study, we taught English/Language Arts teachers of students with learning disabilities in middle school to incorporate 15 min of daily vocabulary activities with students in their intact special education English/Language Arts classes. During Year 1, teachers taught 48 words to their sixth grade students, who learned and…

The purpose of this experimental study is to investigate the effects of using content acquisition podcasts (CAPs), an example of instructional technology, to provide vocabulary instruction to adolescents with and without learning disabilities (LD). A total of 279 urban high school students, including 30 with LD in an area related to reading, were…

Researchers have hypothesized four levels of instructional dialogue and claimed that teachers can improve children's language development by incorporating these dialogue levels in their classrooms. It has also been hypothesized that enhancing children's early language development enhances children's later reading development. This…

Comparison of 38 learning disabled and 38 normally achieving eighth graders on a vocabulary learning task indicated that the two groups did not differ in observable learning strategies used during the study period and that strategy use did not account for vocabulary learning score. (Author/DB)

Adolescents (n=25) with learning disabilities were randomly assigned to either mnemonic conditions or experimenter-directed rehearsal conditions and individually taught difficult vocabulary words, half abstract and half concrete. Results included higher scores on both recall and comprehension tests by mnemonically trained students for both…

Comparison of two computer-assisted instructional vocabulary programs used with 25 learning disabled high school students indicated that the program utilizing smaller teaching sets and cumulative review exercises was more effective in helping students achieve mastery than the program using a large teaching set and no cumulative reviews. (Author/DB)

Discussed are problems in the verbal comprehension and production of personal pronouns by learning disabled children. A learning approach based on echolalia and favoring a focus on the pronoun you which the child hears is advocated. (KW)

The efficacy of a keyword mnemonic strategy to teach word meanings was evaluated with 64, 12-year-old learning disabled poor readers. Subjects were instructed via either keyword-image, picture context, sentence-experience context, or control. Results indicated that the students in the keyword condition significantly outperformed other students…

The effects of intraclass peer tutoring on vocabulary development were studied in primary level learning disabled students. (DLS)

Eighty learning disabled (LD) students at four age levels (ranging from 7 to 14) were studied to compare their vocabulary and syntactic maturity with normal children and to describe the developmental trends (using several instruments). (PHR)

A program was developed to increase the receptive and expressive language skills of 24 secondary learning-disabled students. Program units covered word sorting, sight-word vocabulary, key-word reading, reading rate, reading comprehension, listening, and writing. (Author/SW)

A study examined specific word- and sentence-level features most frequently used in the expository writing of 87 college students with learning disabilities, 50 with attention-deficit/hyperactivity disorder, 58 with both disabilities, and 92 controls. Very high correlations were found between verbosity, quality, and lexical complexity. (Contains…
