Instructional Support Employing Spatial Abilities: using complimentary cognitive pathways to support learning in students with achievement deficits

Several criteria were used for this study to determine the relevance of the literature for the purpose of the review. First, all articles were required to be published in peer-reviewed journals. Next, all articles were required to be primary sources. Reviews of the literature found throughout the search procedures were used as supporting information, as well as the basis for this review. Only quantitative studies were included in this review; opinion papers and qualitative studies were not incorporated into the results. The participants in each study had to be identified as having a learning disability. Studies that included regular education students as a control or comparative group were included as long as the treatment group included students with learning disabilities. The students with learning disabilities were required to possess verbal deficits. Those studies that examined students with non-verbal learning disabilities were excluded from this review. All studies were required to be in English and conducted in the United States.
