Findings Study Design Documents Implementation Resources References Study Year 1 Findings Preliminary results from the first scientific study of OCDE ® (Guided Language Acquisition Design) suggest that the popular instructional model may improve literacy outcomes for English language learners, without slowing down their English proficient peers. For an overview of the study and Year 1 findings, watch the video below. Background In 2010, Education Northwest was awarded a $2.8 million dollar grant from the Institute of Education Sciences (IES) for a four-year experimental study of . Although has been used by almost 50,000 teachers in 13 states to help ELL students develop academic English skills, the model had not previously undergone a rigorous evaluation. The Education Northwest study examines ’s effectiveness through a cluster randomized trial involving fifth-grade teachers and students in 30 Idaho elementary schools. We collected two years of data on the impact of on students’ reading comprehension, vocabulary, science achievement, and writing. We also measured teachers’ implementation. Oregon EL Alliance 2014.ppt Deussen Handout.doc Study Design Education Northwest conducted an independent research study to examine the effects of OCDE ® . This study addresses four research questions. To what extent do teachers implement the teaching strategies promoted by during the training year and the following school year? What is the impact of teacher training on the reading, writing, and science achievement of fifth-grade students in the treatment classrooms during the initial training year, compared to a “business as usual” control group? What is the impact of teacher training on the reading, writing, and science achievement of fifth-grade students in the treatment classrooms during the year following the initial training year, compared to a “business as usual” control group? Is the impact of different for fifth-grade ELLs and non-ELLs? Study Documents GLAD press release.pdf IES Efficacy Study Abstract.pdf GLAD-SIOP Crosswalk.pdf Implementation Examining implementation of OCDE ® was an important component of this study. We wanted to understand how was used by teachers in the treatment group. We also wanted to know whether or not teachers in the control group used , or similar strategies, despite being in the control group. Our measures of implementation included attendance logs at professional development sessions, coaching logs, monthly surveys, classroom observations, and interviews with teachers and principals. Overall, we found that all treatment teachers received the full training and coaching follow-up. All treatment teachers used to at least some extent, although the frequency and quality of implementation varied greatly across teachers. Very few control teachers used strategies similar to strategies. Principal Investigator Theresa Deussen explains why districts should be concerned about implementation.
