Review of Experimental Research on Academic Learning by Students with Moderate and Severe Intellectual Disability in General Education

A review of the literature on academic learning in general education settings for students with moderate and severe intellectual disability was conducted. A total of 17 experimental studies was identified and evaluated using quality indicators for single-case design research. Studies that met or met with reservation the criteria established for quality research were used to determine the evidence base of the instructional strategies described in the literature. The review found embedded instruction trials using constant time delay to be an evidence-based practice for teaching academic content to students with moderate and severe intellectual disability in general education. In addition, strategies that were not yet evidence-based but showed promise in the literature for teaching academic content to students with moderate and severe intellectual disability in general education were described. Last, implications for practice and directions for future research were discussed.

Using an iPad2® with Systematic Instruction to Teach Shared Stories for Elementary-Aged Students with Autism.

Literacy skills are important for accessing all areas of academic content as well as for increasing quality of life. The use of shared stories to teach early literacy skills to students with extensive support needs, including students with autism, is an evidence-based practice. This project extends the research by examining the effects of systematic instruction, including constant time delay and a modified system of least prompts, paired with an iPad2® to teach grade-appropriate literature in a shared story format for students with limited verbal ability. The participants in this intervention were four elementary-aged male students with autism and limited to no verbal ability. A 10-step task analysis was developed to guide the shared story process. Results indicated that the participants were able to increase the number of independent correct responses on the task analysis from baseline to intervention. Study limitations and implications for future research are discussed.

Generalization of Literacy Skills Through Portable Technology for Students With Severe Disabilities

Literacy is an important skill for accessing all academic content areas, and there has been an increased focus on using a variety of assistive technology (AT) to support the acquisition of literacy skills for students with severe disabilities. Literacy also provides these students with skills to increase community participation, with independence, with skills to make individual choices, and with opportunities for potential employment. Portable technology such as an iPad2® can be used to enhance literacy skills for students with severe disabilities in elementary school. A typical way to teach literacy to this population is through the use of a shared story. Although systematic instruction has proven to be an effective teaching strategy, the generality of the literacy skills usually has not been the focus of the training. In this study, five students with severe disabilities (IQ below 55, range in age 7-11 years, grade range 2nd-6th grades) were taught to generalize literacy skills via multiple exemplar training. A multiple probe design across participants demonstrated a functional relation between student responding and the intervention. Extension of what we currently know, limitations, and future research are discussed.

Teaching Students With Intellectual Disability to Use a Self-Questioning Strategy to Comprehend Social Studies Text for an Inclusive Setting

Using a modified system of least prompts, two classroom teachers taught three participants with moderate intellectual disability to generate questions about United States history. After reading brief portions of the text aloud to the participants, the teachers taught participants to identify if the answer to the question was in the book or not in the book. Finally, participants were taught to answer the literal questions that could be answered from the book. Participants had a graphic organizer with WH question words, the text section heading, and a self-monitoring sheet. All participants improved the number of questions generated and answered from baseline to intervention. Additionally, probes collected in a general education setting indicated students improved their question generation and comprehension skills during lessons taught in a fifth grade classroom.

Systematic Instruction of Phonics Skills Using an iPad for Students With Developmental Disabilities Who Are AAC Users

A phonics-based reading curriculum in which students used an iPad to respond was created for students with developmental disabilities not able to verbally participate in traditional phonics instruction due to their use of augmentative and assistive communication. Time delay and a system of least prompts used in conjunction with text-to-speech software enabled students to participate in phonics instruction that included segmenting, decoding, sight words, and comprehension after reading a decodable short passage. Students were randomly assigned to a treatment group who received the phonics instruction or a control group who received sight word instruction on the iPad. A repeated-measures ANOVA found that students who received the iPad-based phonics curriculum outperformed the control students. Hierarchical linear model (HLM) analysis supports a two-level model with a time by group membership interaction effect, the inclusion of student-level variables was not statistically significant.

Effects of a Story-Mapping Procedure Using the iPad on the Comprehension of Narrative Texts by Students With Autism Spectrum Disorder

This study investigated the effects of a modified system of least prompts and an electronic story-mapping intervention for elementary students with autism spectrum disorder. Participants were first taught to identify story element definitions using constant time delay. Participants then listened to age-appropriate narrative texts with a problem–solution structure, completed an electronic story map, and orally answered questions related to the story elements. If unable to complete the map or answer questions, a system of least prompts was used that redirected the students to use provided supports and provided rereads of portions of the text. A multiple probe across participants design was used to examine the effects of the intervention. Outcomes indicated the intervention was effective for teaching story element definitions, labeling of the story element map on an iPad, and comprehension of story element questions. The limitations of the study as well as implications for future research and practice are discussed.

Technology-Based Shared Story Reading for Students With Autism Who Are English-Language Learners

Demonstrating comprehension of text is a complex skill that is an area of difficulty for many students with autism spectrum disorder (ASD). Shared story reading is an intervention that has a history of effectiveness in teaching literacy skills to students with extensive support needs. This study used a multiple probe across participants design to evaluate the effects of shared story reading using e-texts and embedded prompting on vocabulary and reading comprehension of grade-aligned narrative texts by elementary students with ASD who were also English-language learners. Outcomes indicate shared story reading with the embedded technological supports was effective for teaching comprehension of WH questions as well as identification of WH rules and definitions. Implications for future research and practice are discussed.
