Purpose: We tested the effects of the direct teaching intervention for three types of word relations (i.e.,
category and instance, synonym, & antonym) on the emergence of untaught analogical word relations after
reading a paragraph. Methods: Two middle school students with intellectual disabilities participated and an
multiple probe design across participants was employed. The independent variable of this study was the
completion of the direct teaching intervention of three analogical relations with the pre-developed instructional
materials. The dependent variables were the percentage of correct responses to (a) the probe worksheets prior to
and after the direct teaching intervention, and (b) practice tests in the intervention phase. Results: After the
intervention, the percentage of Participant A’s correct responses increased for both probe worksheets. The
percentage of Participant B’s correct responses increased for one out of two probe worksheets. Conclusion: Result
demonstrated that the direct teaching intervention for three types of word relations was effective to acquire the
analogical word concepts and the analogical relationships based on the reading paragraphs.
