Lexia® Core5 Progress Predicts Reading Gains on a Standardized Test
PURPOSE: This study asked whether Lexia® Core5® Reading, as part of blended learning reading instruction, could provide benefits to students across grades K through 5 in an urban elementary school.
METHOD: Gains on the Group Reading Assessment and Diagnostic Evaluation (GRADE) were analyzed across grades for students receiving instruction with Core5. Additional analyses examined if students’ progress in Core5 could predict gains on the GRADE after controlling for grade level, initial skill level, and English Learning (EL) status.
KEY FINDINGS
- Significant gains on the GRADE were more pronounced in early grades (K–2) than later grades (3–5), and students met their Core5 usage targets more consistently in early grades.
- Statistically taking into account grade level, initial skill level, and EL status, advances in Core5 were predictive of gains on the GRADE.
- EL students showed gains on the GRADE equal to or slightly greater than non-EL students.
