The study examined the effectiveness of using model-drawing methodology to solve problems for a group of high school students. The 30-week intervention used a single-subject design to teach an 8-step model-drawing approach for solving problems with fractions and percentages. The results showed improvement in solution accuracy.Word problem-solving is an area of difficulty and frustration for a considerable number of students, and this, to a great extent, could be attributed to a large number of cognitive processes involved in successful problem completion. It is an especially difficult area for those students who are identified with learning disabilities (LD).
