Analysis, Conclusions, & Implications
Subject A’s outcome for reading comprehension should be viewed with caution. The inadvertent administration of the same DRA text for nonfiction text may have impacted the changes observed prior to and following intervention. Additionally, posttest data was not obtained for the fictional text using the DRA. Triangulation of data was not achieved for fictional texts, which weakened the support for the outcome of this study for reading comprehension for subject A.
One important consideration when interpreting subject B's substantial change in score on the expository passage for listening comprehension on the Informal Reading Inventory-7th Edition (B/RIRI-7) was the effect of background knowledge. The first passage administered prior to instruction was on New Zealand and sheep herding. The passage administered following the intervention was on weather. Subject B had studied a unit on weather at the beginning of the year, possibly having a positive and significant impact on listening comprehension for this passage.
