The number of opportunities to respond (OTR) and spacing (massed or distributed practice) of practice sessions are important variables to consider in instructional design. The purpose of this pilot study was to compare the impact of these variables on trajectories of mathematics fluency. Second- and third-grade students (N = 112) were randomly…

This pilot study examined the efficacy of a Tier 2 first-grade mathematics intervention program targeting whole-number understanding for students at risk in mathematics. The study used a randomized block design. Students (N = 89) were randomly assigned to treatment (Fusion) or control (standard district practice) conditions. Measures of…

Reading fluency is a critical component of effective reading instruction for students of early elementary age. However, national data suggest that 40% of U.S. fourth-grade students are nonfluent readers. Implementing evidence-based, time-efficient, and procedurally standardized instructional strategies may help address this problem. This study…

We examined the extent to which use of a technology-enhanced continuous progress monitoring system would enhance the results of math instruction, examined variability in teacher implementation of the program, and compared math results in classrooms in which teachers did and did not use the system. Classrooms were randomly assigned to within-school…
