The Effects of the Self-Determined Learning Model of Instruction on Academic Performance of Students with High-Incidence Disabilities

This study examined the impact of the Self-Determined Learning Model of Instruction (SDLMI) in promoting student academic performance in science class for three middle school students with high-incidence disabilities. Using the SDLMI, the students set their goals, developed action plans, implemented and adjusted their plans, and evaluated their progress. This study used a multiple baseline across participants design and the entire study took 12 weeks to complete using oneto-one instruction, with each intervention session ranging from 15 to 25 minutes. The results indicated that all students achieved self-selected goals to mastery levels. Also, most stakeholders indicated positive opinions about implementing the SDLMI. Implications and future directions for research and practice are discussed.
