The purpose of this study was to examine the effects of schema-based instruction (SBI) on the correct response of 2 second-grade students at risk for or already determined to have a learning disability (LD) of comparison difference word problems. The study was a multiple probe across participants. Although the students did not use the RUN Strategy, one student’s ability to solve the word problems improved significantly after learning the strategy. Even though time was a factor in completing everything, the other student’s score did begin to improve after learning the RUN Strategy
