The purpose of this dissertation is to evaluate the effectiveness of graphic organizers, specifically flowcharts, as a tool to support decision-making during spelling for students identified with learning disabilities. This dissertation is composed of five chapters. The first chapter is an introduction about how graphic organizers support students with executive functioning difficulties, a common challenge for students with learning disabilities. The second chapter is a systematic literature review analyzing the current literature about the effects of reading, writing, and spelling interventions for students with learning disabilities. The third chapter is a research study that used single-case research methodology to evaluate the effectiveness of a spelling flowchart on outcomes for students with learning disabilities. The fourth chapter is a practitioner paper that provides educators with strategies for using flowcharts and multiple exemplars for incorporating them as decision-making tools in the classroom. Finally, the fifth chapter details my future career goals and research aims. [The dissertation citations contained here are published with the permission of ProQuest LLC.
