The purpose of this efficacy follow-up study was to evaluate the long-term effects of a teacher professional-development program based on Cognitively Guided Instruction (CGI) on school mathematics achievement in grades K through 5, which had been previously evaluated under an earlier IES grant (R305A120781). A further purpose was to conceptualize and develop an observational measure of the facets of mathematics instruction that are consistent with implementation of CGI principles to be used ...

Cognitively Guided Instruction (CGI) is a widely used professional development program for mathematics instruction in elementary school. Researchers propose to replicate a previous efficacy study to examine the impact of this intervention on student achievement in mathematics when implemented with a larger and more diverse sample of students. The study also seeks to identify the principal, teacher, and student characteristics that moderate intervention impact and to explore the mechanisms t...

In 2009, 43 percent of English language learners (ELLs) in 4th grade scored below basic proficiency on the NAEP mathematics test, and this percentage increased to 72 percent among 8th graders and 80 percent among 12th graders. Many schools lack wide-spread expertise in how to address the instructional and language learning needs of ELLs. In particular, little attention has been devoted to understanding how ELLs learn the conventions and expectations for language use in mathematics in order ...
