A tool to evaluate students’ performance in solving fraction word problems

Résumé

In this paper a tool to evaluate students' performance in solving particular fraction word problems is described. It is a pencil and paper test with seven tasks, which have been designed ad-hoc from a previous historical-epistemological study of this kind of problems. The tasks have in common that all of them involve iterative processes to calculate part of the part complement. The test was validated through reliability and content validity. The difficulty of each task was obtained through the resolution success probability based on the analysis of the responses of 202 Mexican students between 15 and 16 years old. Difficulty of the task is increased when its structure is more complex. Suprisingly, only a small number of students used algebra to solve the problems.
