2. Method
Academic search complete and ERIC were searched for articles published after 2000 that examined an
intervention or strategy for teach reading for students with intellectual disabilities. The criteria for including
studies in this literature review were two; first is examining intervention or strategy to improve reading skills or
sub-reading skill; second is that participants in the study or part of them were students with intellectual
disabilities. Nine studies were designed as experimental with two groups; treatment and control group. Single
subject research designs were utilized for five studies. One study used a descriptive design with hierarchical
regression analysis of the data, and one study covered 128 studies as intensive literature review. Three hundred
and ninety four students with intellectual disabilities were included in these studies.
