Lexia® Core5® Reading Benefits Students in Kindergarten and First Grade

PURPOSE: This study examined the potential benefits of using Lexia® Core5® Reading as part of blended learning instruction in an urban school district.

METHOD: The impact of Core was assessed in a large sample of students attended kindergarten and first grade classes. Using a quasi-experimental design, two schools in the district were assigned to use Core5 as part of blended learning instruction while two schools continued with their traditional instruction. Reading scores on DIBELS Next were used to compare students in Core5 and non-Core5 schools. Students in non-Core5 schools had significantly higher pretest scores than students in Core5 schools; thus, propensity score analyses were used to compare Core5 and non-Core5 students at posttest

KEY FINDINGS 

• Students who used Core5 significantly outperformed non-Core5 students on DIBELS Next at posttest. 
• The discrepancy between Core5 and non-Core5 students was larger for students who had low pretest scores. 
• When comparing two hypothetical students with the same below average pretest scores, the Core5 student was projected to score 29 points higher at posttest than the non-Core5 student.
