In the present study, mobile technology was leveraged as a learning tool for core math instruction during a whole number multiplication and division unit. The researchers redesigned paper--pencil worksheets from the math curriculum into multimedia-enhanced, interactive math practice (the eWorkbook) accessed by students on an iPad. With this eWorkbook, which was conceptualized within a Universal Design for Learning framework, we aimed to reduce barriers and capitalize on strengths by embedding flexible scaffolds/supports, allowing for student choice, and incorporating evidence-based teaching practices. Results of this case study suggest students with and without learning disabilities can leverage multimedia to foster unique opportunities for the understanding and expression of mathematical knowledge. Additional affordances of the eWorkbook include extending the reach of teacher support while encouraging self-support. Implications for teachers and researchers are discussed.
