Physics · Pedagogy of Science

In a senior secondary Physics class, students are introduced to the importance of standardization in scientific communication. The teacher demonstrates how early civilizations relied on arbitrary body-based measures, leading to inconsistencies. To illustrate the need for universal agreement, the class compares measurements taken using different informal units. The teacher then shifts the discussion to modern scientific practice, emphasizing that repeatability, accuracy, and international collaboration require a unified system of units. Which framework best supports the idea of establishing universally accepted scientific units?
