Diagrams in problem solving: difficulties in generating and using them by 4th grade students
Abstract
The present study examines students’ difficulties while generating and using diagrams to solve one-step addition and subtraction word problems before and after a teaching intervention for the use of diagrams. For this purpose two tests (pretest and posttest) were given to 45 fourth-grade students, who were asked to solve three problems with the prompt to generate and use diagrams. Difficulties were classified into three categories regarding the understanding of the concept of a diagram, the ability to generate and to use one. Results indicated that at the pretest all students experienced difficulty in understanding the concept of a diagram and therefore use it. After the teaching intervention, students' difficulties were limited and mostly related to the generation of a diagram in terms of completing the requested data in the correct place or using it mainly in Comparison and Change problems.
