Understanding the Role of Measurements in Creating Physical Quantities: A Case Study of Learning to Quantify Temperature in Physics Teacher Education

Learning to understand the content and meaning of physics’ concepts is one of the main goals of physics education. In achieving this understanding, the creation of quantities through quantitative measurements, or rather through quantifying experiments, is a key process. The present article introduces a didactical reconstruction for understanding the construction of the meaning of physical quantities from a network point of view, where the quantities are part of networks and the quantifying experiments build up these networks. As a practical example, we discuss how the quantity temperature is constructed in an instructional unit designed for student teachers and what the learning outcomes are.
