Brief Summary
This project will (a) examine the relationship between knowledge retrieval and inferencing; (b) determine the effectiveness of an intervention that improves knowledge retrieval and inferencing among struggling readers; and (c) expand research opportunities for undergraduates. The research design uses 316 struggling readers in grades 4-6 of diverse backgrounds. The effects of knowledge retrieval (accuracy and speed) on inferencing will be modeled without dichotomizing the distribution. Linear mixed effect models will be fit to determine whether reader characteristics make unique contributions to inferencing across the posttest and follow-up data collection time points. First, several structural models will be considered as students may be nested in teachers, schools, and tutors. Unconditional models will estimate the intraclass correlation for each level of the study design. If significant interclass correlations emerge, multilevel models will be fit to evaluate the effectiveness of the intervention while controlling for covariates such as pre-test performance on inference-related measures and child-attributes such as English learner status. The primary analysis plan assumes an intent-to-treat model in which the efficacy of two intact conditions will be tested. Effect sizes will be estimated to report the magnitude of difference between the two conditions. Expected outcomes include (a) the identification of a method that effectively facilitates knowledge retrieval and the application of relevant knowledge to form inferences among elementary struggling readers from diverse backgrounds; (b) the validation of an intervention that teaches struggling readers how to activate, retrieve, and interweave relevant knowledge with information in the text and accurately form inferences while reading that can be broadly implemented in general education classrooms; and (c) expansion of undergraduate research opportunities, particularly among students from diverse backgrounds who have been historically underserved.

Variable Test
EXPERIMENTALStudents will be taught a knowledge base comprised of 18 facts about Egypt. After learning the knowledge base to criterion, students will practice retrieving the knowledge base across four testing sessions spaced 24 hours apart. Students will receive different questions across testing sessions. Next, students will read 6 passages about Egypt and then answer literal and inferential questions about the passages. Immediately after reading the passages, students will get re-tested on their retention of the knowledge base and use of the knowledge base to form inferences. They will also get retested one week and one month later to examine students' long-term retention of the knowledge base and use to make inferences.
Repeated Test
EXPERIMENTALStudents will be taught a knowledge base comprised of 18 facts about Egypt. After learning the knowledge base to criterion, students will practice retrieving the knowledge base across four testing sessions spaced 24 hours apart. Students will receive the same questions repeated across testing sessions. Next, students will read 6 passages about Egypt and then answer literal and inferential questions about the passages. Immediately after reading the passages, students will get re-tested on their retention of the knowledge base and use of the knowledge base to form inferences. They will also get retested one week and one month later to examine students' long-term retention of the knowledge base and use to make inferences.
Placebo
PLACEBO COMPARATORStudents will be taught a knowledge base comprised of 18 facts about Egypt. After learning the knowledge base to criterion, students will re-read the passages. They will not receive any questions. Next, students will read 6 passages about Egypt and then answer literal and inferential questions about the passages. Immediately after reading the passages, students will get re-tested on their retention of the knowledge base and use of the knowledge base to form inferences. They will also get retested one week and one month later to examine students' long-term retention of the knowledge base and use to make inferences.
Interventions
Students will learn a new knowledge base to perfect mastery. Following the attainment of mastery students will read passages on the topic and answer questions that prompt the literal recall of key facts and the formation of inferences.
The intervention will pre-teach students a set of 20 essential facts about Egypt. Students will interact with expository and narrative texts. Students will practice using a text clue strategy to activate and integrate prior knowledge, will make in-text connections, connections across the 3 intervention texts, and connections between text and knowledge, and will make inferences about character motives and author intent. The tutor will ask students to justify connections and evaluate how these connections enhance understanding. Students will answer inference questions that require using text and background knowledge. A simple graphic organizer will support and scaffold inferencing. Throughout the intervention, students will practice retrieving the 20 essential facts about Egypt from memory using flash cards, completed in pairs with students providing each other feedback.
