Applying the Universal Design for Learning Framework to Mathematics Instruction for Learners With Extensive Support Needs

The purpose of this study was to evaluate the effect of a mathematics intervention that utilized the Universal Design for Learning (UDL) framework on mathematical problem solving skills for three middle school students with extensive support needs (ESN). Participants were taught to solve percent of change word problems related to personal finance (calculating the final price after leaving a tip or purchasing a discounted item). Visual analysis of the multiple probe across participants design indicated a functional relation between the mathematics intervention and an increase in mathematical problem solving skills. Results are discussed in terms of acquisition and generalization of mathematical problem solving skills. Implications for application of the UDL framework to mathematics instruction for learners with ESN are discussed.
