Abstract
This article explores the values that come to the fore when preservice mathematics teachers (PTs) 11In the remaining parts of the text, we will refer to preservice teachers as PTs. engage in critical discussions about the role of mathematical models in society. The specific model that was discussed was the Body Mass Index (BMI) 22From now on, the Body Mass Index will be referred to as BMI and is calculated as mass (m) divided by the square of height (h).. From the analysis of the PTs’ discussions of the BMI from a mathematical and societal point of view several mathematical and mathematics educational values were identified such as openness, rationalism, progress, reasoning, evaluating, and problematizing the instrumental understanding of mathematics. In addition, critical thinking about mathematics in society as emphasized in curricula in the three countries involved in the study, was identified with four categories of complementary pairs. Knowing the mathematical and mathematics educational values underpinning PTs’ discussions and their connection to critical thinking is important for successfully engaging with the role of mathematics in society.
