This study employs a sequential multiple assignment randomized trial (SMART) design to develop an adaptive intervention with personalized print and digital content for kindergarten to Grade 2 children (n = 273). In Stage 1, we ask whether it is better for children to receive an adaptive intervention based on (a) 10 conceptually coherent texts or (b) 10 leveled texts on a range of topics. In Stage 2, we ask how best to encourage nonresponding children. Findings indicate that children who received either conceptually coherent texts or leveled texts performed similarly on reading comprehension posttests, while augmenting and intensifying follow-up with gamification of the app . . .

The present study examined potential synergistic relationships between reading engagement and reading comprehension among 3,689 third and fourth graders across 59 schools in North Carolina. Using hierarchical regression analyses, we replicated previous findings that reading engagement explains unique variance in reading comprehension. Our results indicated that reading engagement explained an additional 4% of variance in end-of-year reading comprehension above and beyond initial skill, student demographics, and school membership. We then utilized multilevel modeling to examine the tenability of two common hypotheses in the literature: that reading engagement is more strongly related to the reading comprehension of below-average readers (the compensatory hypothesis) and that reading engagement is more strongly related to the reading comprehension of above-average or competent readers (the cognitive-constraint hypothesis). Students were broken into above-average, average, and below-average skill groups based on their beginning-of-year score on a nationally normed assessment of reading comprehension. Results supported the cognitive-constraint hypothesis that the relationship between reading engagement and reading comprehension is attenuated for below-average readers. The strength of the relationship for average and above-average readers did not significantly differ, suggesting homogeneity in the strength of the relationship among these students.
Qin, W., Kingston, H. C., & Kim, J. S. (2019). What does retelling ‘tell’ about children’s reading proficiency? First Language, 39(2), 177–199. 10.1177/0142723718810605
Book retelling has been frequently used as an indicator of children’s reading proficiency. However, how children’s performance varies across retelling narrative and expository texts and whether that has different implications for reading proficiency remains understudied. The present study examined 85 high-poverty second- and third-graders’ retelling of narrative and expository books. A parallel coding scheme was developed to evaluate children’s performance on retelling fluency, content, and language complexity. Children’s retelling performance was compared across text types and analyzed in relation to reading proficiency. Findings revealed similarities and differences in retelling across text types, with narrative retelling containing a higher proportion of content-matched T-units, whereas expository retelling contained a higher proportion of inference generation and more complex syntactic structures. Moreover, indicators of reading proficiency were found to vary across text types. Findings highlight the distinct cognitive and linguistic demands posed by reading narrative and expository texts and provide implications for effective instruction and assessment.

Children's motivation to read is a strong predictor of their reading comprehension. However, some recent research has suggested that the relationship between reading motivation and reading comprehension may be mediated through the amount that students read. This study attempts a conceptual replication of several existing models that explore the relationship among children's reading motivations, out-of-school reading amount, and reading comprehension, using a large sample of over 4000 third- through fifth-graders in 59 U.S. elementary schools. Consistent with prior research, several control variables, including children's prior reading comprehension ability, gender, and socioeconomic status, directly contributed to later reading comprehension. Results also replicated positive associations between intrinsic reading motivation, reading amount and reading comprehension, and negative associations between extrinsic reading motivation, reading amount and reading comprehension. Using structural equation models, our analyses found no evidence that the relationship between children's intrinsic and extrinsic reading motivation and later reading comprehension was either partially or fully mediated by reading amount. This suggests that it is critical to attend to context-specific determinants of motivation and reading amount, including students' background characteristics and quality of texts read. Furthermore, this study underscores the importance of replicating methods used by original researchers to confirm and disconfirm hypotheses, and of conducting research with large and diverse samples that enhance the generalizability of results.

Theory and empirical work suggest that teachers’ social capital influences school improvement efforts. Social ties are prerequisite for social capital, yet little causal evidence exists on how malleable factors, such as instructional management approaches, affect teachers’ ties. In this cluster-randomized trial, we apply a decision-making perspective to compare a literacy intervention managed under a “fidelity-focused” approach, in which teachers were expected to implement researcher-designed procedures faithfully, versus a “structured adaptive” approach, in which teachers collaboratively planned program adaptations. In the short term, the adaptive approach increased teachers’ accessing of intervention-related social capital, but decreased their accessing of social capital unrelated to the intervention. Short-term effects varied based on participants’ role in the intervention. No group differences were found on social capital measures one year later, suggesting that the structured adaptive approach did not make teachers more likely to form ties that would be useful outside of the intervention.

In a common approach for scaling up effective educational practice, schools adopt evidence-based programs to be implemented with fidelity. An alternative approach assumes that programs should be adapted to local contexts. In this randomized trial of a reading intervention, we study a scaffolded sequence of implementation in which schools first develop proficiency by implementing the program with fidelity before implementing structured adaptations. We find evidence supporting the scaffolded sequence: A fidelity-focused approach promoted learning and instructional change more so for teachers inexperienced with the intervention, while a structured adaptive approach was more effective for teachers experienced with the intervention. Students benefited more from the structured adaptive approach but only when their teacher had prior experience with the fidelity-focused version.

The authors conducted a cluster-randomized trial to examine the effectiveness of structured teacher adaptations to the implementation of an evidence-based summer literacy program that provided students with (a) books matched to their reading level and interests and (b) teacher scaffolding for summer reading in the form of end-of-year comprehension lessons and materials sent to students’ homes in the summer months. In this study, 27 high-poverty elementary schools (75–100% eligibility for free or reduced-price lunch) were matched by prior reading achievement and poverty level and randomly assigned to one of two implementation conditions: a core treatment condition that directly replicated implementation procedures used in previous experiments, or a core treatment with structured teacher adaptations condition. In the adaptations condition, teachers were organized into grade-level teams around a practical improvement goal and given structured opportunities to use their knowledge, experience, and local data to extend or modify program components for their students and local contexts. Students in the adaptations condition performed 0.12 standard deviation higher on a reading comprehension posttest than students in the core treatment. An implementation analysis suggests that fidelity to core program components was high in both conditions and that teachers in the adaptations condition primarily made changes that extended or modified program procedures and activities in acceptable ways. Adaptations primarily served to increase the level of family engagement and student engagement with summer books. These results suggest that structured teacher adaptations may enhance rather than diminish the effectiveness of an evidence-based summer literacy program.
