The Impact of Project GLAD on Students’ Literacy and Science: Year 1 Results From a Cluster-Randomized Trial of Sheltered Instruction

• In Event: Innovation in Science Education and Evaluation

Abstract

With the increased numbers of English learners (ELs) in US schools, educators need programs that help ELs access academic content while developing English proficiency. Project GLAD is a K-12 instructional model designed to meet this need. This study is the first rigorous trial of the efficacy of this program, widely used in the western US. We conducted a two-year cluster randomized trial of Project GLAD in fifth-grade classrooms in 30 Idaho schools. In this paper, we report on the Year 1 impact on students’ reading comprehension, vocabulary, writing and science achievement.
