Abstract

The purpose of this study was to analyze students’ mathematical modeling on PISA quantity problems which concerns formulating contextual situations mathematically. A total of 310 eighth grade students of a state secondary school in Sidoarjo, Indonesia, were involved in a task-based questionnaire whose responses were then analyzed using the stages of understanding the problem, making mathematical models, solving mathematical models, interpreting model solutions in real situations, and validating solutions. The results showed that 21 students made mathematical models explicitly, 29 students made models implicitly and the remaining participants did not create any mathematical model, or the model is incomplete. The explicit model made by the students is one model that represents the whole problem, while the implicit model is in the form of two models, each of which describes one part of the problem, and then they are combined. Of the five stages of mathematical modeling, constructing mathematical models, interpreting model solutions, and validating solutions are found problematics for the student participants.
