Summary of Findings
This report summarizes implementation, assessment data, and outcomes from a 5-month trial of a phonics program, Reading Horizons Discovery® in a school district in the Illinois area. Seventy-one teachers in nine schools in the district participated in eight days of training then, during implementation, received 20 days of coaching in teaching the Reading Horizons Discovery program. General and special education teachers participated in the trial as well as teachers with specializations in English Language Learning and Bilingual instruction. Students in kindergarten through second-grade classrooms received Reading Horizons Discovery instruction from November 2016 to April 2017, directly from their teacher and through specialized program software. An assessment developed by MetaMetrics® to provide a Lexile measure for each student (housed in the Reading Horizons Discovery software as the Reading Horizons Discovery Reading Assessment, referred to as the RHD Reading Assessment in this document) and an assessment created by Reading Horizons (the Reading Horizons Discovery Spelling and Word Recognition Assessment, referred to as the Spelling and Word Recognition Assessment in this document) were utilized to measure outcomes in this trial. For comparison, students in Kindergarten through second grade in four schools in the surrounding area participated in the Reading Horizons Discovery assessments, although they did not receive Reading Horizons Discovery instruction, nor were teachers in those classrooms trained in the method.
Test scores from both experimental and comparison classrooms were released, with permission, to the Reading Horizons company and then shared with an educational research company, Clear Insight, for summarization of data by a third-party.
Direct instruction and interactive software. All teachers were trained in the method.
Dynamic Indicators of Basic Early Literacy Skills (DIBELS), the Reading Horizons Discovery® Reading Assessment powered by the Lexile® Framework for Reading, administrator surveys, teacher surveys
Outcomes represented in this report are based on a trial use of Reading Horizons Discovery, and, based on these and other positive outcomes, including social validity data, administrators at the district determined that teachers would continue using Reading Horizons Discovery in their classrooms. Past and future standardized test data will be analyzed as additional measures of effectiveness.
