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).
Recently, a considerable amount of work has been done to examine the sources of difficulties in problem-solving, predictors of success, and the best practices and programs aimed at helping struggling learners to better problem-solve. Research findings indicate that the reduction of demands on the working memory system (WM) seems to be highly beneficial. Different ways to minimize these demands on the WM system have been tested (e.g. use of visual support via pictures, diagrams & schemas, and use of cognitive strategies).
