State standards include fluent use of standard computational algorithms. However, learning and using them require conceptual understanding of numbers and operations. Previous research using the concrete--representational--abstract (CRA) sequence has been effective in teaching computational algorithms to students at risk of and students with…

This study compares the effects of a concrete-representational-abstract (CRA) intervention against a modified CRA-Integrated (CRA-I) intervention using a pretest-posttest design with random assignment of matched pairs to intervention conditions. The researchers designed both interventions to improve participants' understanding of and ability to…

This study investigated the effects of a Direct Instruction (DI) reading comprehension program on the reading comprehension skills of students with autism spectrum disorder or developmental delay. Although the effectiveness of DI programs has been well documented in disability and instructional literature, effectiveness of DI for individuals with…

Counting skills are foundational for young children to build number concepts in mathematics. Multitiered instruction that involves core instruction as well as supplemental interventions is implemented to support young children in the learning process and promote early intervention of basic skills. Researchers show that explicit instruction is…

Language intervention using Direct Instruction (DI) has shown positive results. There is a growing body of investigation of Language for Learning (LL), a DI program, on the performance of students with autism spectrum disorders (ASD) and students with developmental delays (DD). There is need for replication and extension of research to include…

Students with high-incidence disabilities struggle with reading comprehension due to difficulties in background knowledge and metacognitive skills, including use of self-monitoring and other strategies. In the United States, these students typically receive the majority of their instruction in general education settings. However, there is little…

The current exploratory study investigated the effects of a Direct Instruction program implemented with middle school students identified as at-risk for failure in mathematics. Direct Instruction has typically been implemented with students with disabilities in separate special education settings. However, this study examined the extent to which…
