Implementation of evidence-based practices (EBPs) is paramount to students' development of mathematics proficiency. This study investigated "practice-based evidence" of interventionists' actual use of explicit mathematics instruction, a well-established EBP. Specifically, this study analyzed direct observation data collected in a…

This pilot study evaluated a novel professional development (PD) model designed to prepare K-12 educators in high-need rural school districts to teach evidence-based argument writing. The PD model showed teachers how to engage students in discussions about visual art using Visual Thinking Strategies (VTS) to enhance students' argumentation…

This paper reports the outcomes of an experimental evaluation of "Direct Instruction Spoken English" ("DISE"), an English language curriculum that focuses on developing English speaking, listening, and comprehension skills in English Learners (ELs). Twenty-nine middle schools in three states were randomly assigned to teach…

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…

Oregon's Effective Behavioral and Instructional Support Systems (EBISS) initiative was implemented in 25 school districts. The initiative trained and coached district leaders and teachers in the use of the EBISS model through the lens of implementation science. The EBISS model integrates school-wide positive behavior intervention and supports…

We report on a practitioner implementation of Fusion, a first-grade mathematics intervention. Studies such as this evaluation of a loose implementation under realistic conditions are important to curriculum developers' understanding of how evidence-based programs and tools work under a variety of implementation scenarios. In this…
