Matching a graph with an image representing the situational context: Students’ approaches identified by using eye tracking
Résumé
Data from real-world contexts are often represented in graphs. The interpretation of these contextual graphs is a major challenge for students. A common misconception that, for instance, reveals students’ difficulties is the iconic interpretation of graphs. It occurs when students match a graph with an image representing the situational context. The aim of our study is to trace students’ approaches when matching a graph with an image of the situational context. A promising method to investigate students’ approaches when interpreting graphs is eye tracking. In our study, we used eye tracking in combination with stimulated recall interviews to investigate how 19 students in grade nine approached matching graphs with images representing the situational contexts. We illustrate our findings through four student examples: The results indicate that the approaches differ considerably, but have in common that they mainly rely on two strategy elements.
