The primary aims of this mixed method study were to (a) examine the effectiveness of a brief inference intervention, (b) compare the types of knowledge-based inferencing errors less skilled middle grade readers make, and (c) evaluate if self-reported cognitive load relates to inferencing. Participants (n = 17) were randomly assigned to a graphic organizer-inference intervention (GO-Inference) (n = 9) or business as usual (BAU) condition (n = 8), and differences between groups were explored for each study purpose. Quantitative and qualitative results suggested that while less skilled readers in the GO-Inference condition made modest progress in forming knowledge-based inferences, they continued to struggle to distinguish relevant versus irrelevant information from text and/or retrieve knowledge necessary to form inferences. Students in the BAU condition were more likely to make errors such as providing irrelevant information or failing to respond. Additionally, students in the GO-Inference condition reported lower cognitive load during inference-making tasks.
Reading comprehension is an essential academic skill (Nash & Snowling, 2006; National Reading Panel, National Institute of Child Health and Human Development, 2000). Yet, among students in the eighth grade, approximately 64% of all students and 91% of students with disabilities do not read at proficient levels (National Center for Education Statistics [NCES], 2013). This suggests that when reading grade-level texts, a large percentage of middle-grade readers are not able to accurately connect important ideas in text, form inferences that integrate information in text with general knowledge of the topic, and synthesize common ideas across various texts (NCES, 2013). These data highlight the need for intensive reading interventions that explicitly teach middle-grade struggling readers how to comprehend grade-level texts and acquire content knowledge from the texts they read.
