A critical aspect of intervention research is investigating the active ingredients that underlie intensive interventions and their theories of change. This study explored the rate of instructional interactions within treatment groups to determine whether they offered explanatory power of an empirically validated Tier 2 kindergarten mathematics…

Accumulating research has established explicit mathematics instruction as an evidence-based teaching practice. This study utilized observation data from a multi-year efficacy trial to examine the longitudinal effects of a core kindergarten mathematics program on the use of explicit mathematics instruction among two distinct groups of teachers: one…

The use of data-based decision making (DBDM) in schools to drive educational improvement and success has been strongly promoted by educational experts and policymakers, yet very little is documented about the actual DBDM practices used in schools. This study examines DBDM practices in 25 middle schools through 80 standardized observations of data…

As education policy in the U.S. focuses increasingly on the quality of classroom instruction, there is a growing need to identify valid constructs and develop reliable tools that measure student opportunities to learn academic knowledge and skills. The purpose of this study is to examine the relative contributions of two different classroom…

The purpose of this 4-year efficacy trial, funded by IES under the Mathematics and Science Education topic, is to study the efficacy of a (Tier 1) core kindergarten math curriculum, "Early Learning in Mathematics" (ELM), when implemented under rigorous experimental conditions. In the first year of this study (2008-09), kindergarten…

Validation of a classroom observation measure for use with English Learners (ELs) in grade 1 was the focus of this study. Fourteen teachers were observed during reading and language arts instruction with an instrument used to generate ratings of instructional quality on a number of dimensions. In these classrooms we assessed the reading…

The first portion of this article describes the development and validation of a classroom observation measure. The goal of the measure was to assess the quality of reading instruction provided to first-grade English learners. We report the internal consistency reliability, interrater reliability, the development of empirically derived subscales,…

Validation of a classroom observation measure for use with English Learners (ELs) in Grade 1 is the focus of this study. Fourteen teachers were observed during reading and language arts instruction with an instrument used to generate overall ratings of instructional quality on a number of dimensions. In these classrooms, the reading performance of…
