The purpose of this study was to investigate the evidence base for using computer-assisted instruction (CAI) to improve the reading comprehension of students with learning disabilities (LD). Twelve peer-reviewed studies (seven comparison group studies, five single-case studies) met selection criteria and were evaluated according to the relevant What Works Clearinghouse (WWC) procedures and standards. Results showed that seven studies (five comparison group and two single-case studies) met WWC standards with or without reservations. Key instructional features employed in CAI studies meeting the WWC standards without reservations included practice opportunities, self-correction and immediate corrective feedback, teacher-directed instruction, and contingencies for enhancing student motivation and engagement. Implications for future research and suggestions for using quality indicators to improve the rigor of future CAI investigations are discussed.

This study aimed at revealing the reality of teacher’s use of learning resources rooms of graphic organizers in teaching students with learning disabilities, and the difficulties the teachers face while teaching these students. The study sample consisted of 83 of resource room teachers in Irbid Directorates of Education schools, to achieve the goals of the study, a questionnaire of 28 items was developed; 16 were used to reveal the reality of teachers’ use of learning resources, 12 items were used to reveal the difficulties that limit the teachers’ use of learning resource rooms of graphic organizers. The study also attempted to find the effect of certain variables such as gender, scientific qualifications and years of experiences on the teachers’ use of learning resource rooms of graphic organizers in teaching students with learning disabilities. The results of the study revealed the following: 1) In terms of the use of graphic organizers, the average of the means was 2.13 with a low level, and in the terms of difficulties, the average of the means was 2.77 with a high level. 2) There were significant differences among the means due to gender and in favor of males; due to level of qualifications and in favor of high diploma and, master degree; and due to years of teaching experiences and in favor of those who taught more than 10 years. The study reported certain recommendations for professionals and researchers.

In this meta-analysis of single-case designs, the researchers investigated the effects of word-problem instruction for students with learning disabilities in Grades 1 through 12, as reported in 20 peer-reviewed articles published between 1975 and 2020. A two-level multilevel model with a robust variance estimation method was implemented to calculate the effect sizes. A significant overall effect of word-problem instruction for students with learning disabilities was found, and the results indicate that studies meeting all three quality indicators of implementation fidelity (i.e., adherence, dosage, and regularity) showed greater effects. The average weighted effect sizes of word-problem instruction varied depending on the content and practice standards of the Common Core State Standards for Mathematics. Limitations and future research directions are also discussed.

The purpose of this single case design study was to examine the efficacy of using double-bubble Thinking Maps to improve the reading comprehension of middle school Spanish-English bilingual middle school students with learning disabilities. Participants included three female Spanish-English bilingual middle school students with learning disabilities. In this multiple baseline across participants single case design study, we taught students to create a double-bubble map, a type of compare and contrast graphic organizer, for 12 expository compare and contrast text passages over 12 forty-five minute sessions. We assessed performance on creating the double-bubble map and on reading comprehension measures across baseline, intervention, and maintenance phases. Each participant learned to create an accurate double-bubble map for compare and contrast expository texts within two sessions. Reading comprehension scores began to increase within two intervention sessions for each participant. Results showed the positive effect of using the double-bubble Thinking Map to improve reading comprehension of compare and contrast texts. Individual (.895–.967) and overall TAU-U effect sizes (.94) showed the intervention to be highly effective. Based on the effect sizes, the double-bubble Thinking Map was effective for improving the reading comprehension of middle school Spanish-English bilingual students with learning disabilities.
