With limited educational resources and numerous other variables that complicate effective teaching, educators need to think prudently about how to allocate resources. In essence, teachers must allocate resources in ways that will best maximize student learning. However, minimal research has systematically evaluated whether increased instructional intensity and resources meaningfully increase instructional effectiveness. As a preliminary attempt to address this research question, this study systematically evaluated the differential effectiveness of three intervention options that integrated the same instructional components but required varying levels of resources (i.e., teacher time for instructional delivery). To better isolate the research question, this study specifically evaluated interventions designed to improve students' reading fluency. Overall findings suggested that increased instructional intensity does not necessarily equate with increased instructional effectiveness. (Contains 1 table and 2 figures.)
