However, at the end of the 10 weeks of the study, the two groups had a total of 51 students after 9 of them dropped from the study after moving to other regions.
As highlighted, there was a control group and a treatment group, each consisting of 30 students. Both the control group and the treatment group participated in Tier 1 learning instructions, but only the treatment group underwent the special Tier 2 learning instructions. These types of instructions were given for a period of 10 weeks and different measures of their improvement in literacy were used to compare their performance after the 10 week period. The data from such scores was analyzed and interpreted to compare the effect of Tier 2 learning instructions, which was a response-to-intervention model.
From the findings, in the scores of the different groups, it emerged that students in the treatment grouped performed better in all the measures compared to those in the control group. Notably, the control group exhibited improvement because of the Tier 1 learning instructions.
The study utilized a limited sample size, which was 51 at the end of the 10 weeks, a factor that necessitates an additional study with a larger sample size. The measurement instruments used in the study had limited capacity in assessing some measures identified for the study. The third limitation was that, the study only considered reading level ranges from early first to the level of middle third grade, which has the capacity of introducing a level of variance.
This study is a salient example of the effects of adopting an intervention model of learning instructions in a bid to help students with learning disabilities to improve their literacy levels. The authors of this article are impressed by the positive findings that adopting a Tier 2 instruction model can register a difference in the learning ability and literacy levels of students ...Show more
