Abstract
Exploration, construction, validation and use of statistical models are foundational aspects of students’ modelling process for informal inferential reasoning. In this study, a class of middle school students (aged 12-13) was posed a problem rooted in a crisis of society (obesity) to examine the nutritional value of their lunch boxes. The context of the problem offered an opportunity to engage students in the exploration, construction, validation and use of statistical models with real and authentic data to support inferences and to reflect on their own nutrition. The main sources of data were students’ discourse in the classroom, students’ artifacts and researcher journal. Analysis of the data gathered provided insight into students’ process of modelling and insight into the influence of context in informal inferential reasoning.
