Designing, developing, and implementing a multi-year randomized control trial targeting what works in gifted education mathematics study is challenging, at best. In response to the United States Department of Education's Institute of Education Sciences request for proposal, we carefully constructed a mixed-methods study by assembling a diverse…

Modern classrooms are often comprised of a heterogeneous student population with varying abilities. To address this variance, third-grade teachers implemented researcher-designed, pre-differentiated, and enriched math curricula in algebra, geometry and measurement, and graphing and data analysis. The goal of the curricula was to provide academic…

The purpose of this case study was to demonstrate the influence of Tier 1 of Response to Intervention and Instruction (RtI[superscript 2]) and instructional coaching on teachers' instruction and on students' and English Language Learners' (ELL) learning. Research was conducted in one large urban elementary school. The unit of study…

This case study examined three K-5 schools, one 3-5 school, and two K-2 schools that implemented Michigan's Behavior and Learning Support Initiative (MiBLSi) and showed improvement trends in third grade reading achievement as measured by MEAP results over four years. Each of the six schools completed the three years of MiBLSi training and are…

In this article we explore young children's development of mathematical knowledge and reasoning processes as they worked two modelling problems (the "Butter Beans Problem" and the "Airplane Problem"). The problems involve authentic situations that need to be interpreted and described in mathematical ways. Both problems include tables of data,…
