Students’ alternative conceptions were reinforced by the contrast between personal experiences and scientific conceptions. Students held certain intuitive thinking about everyday experiences for heat and temperature concepts. For example, the concept of thermal equilibrium did not make sense to students’ experiences in the term of sensation. Thus, students’ understanding was grounded in everyday experience which was perhaps the one reason of students’ alternative conceptions of heat and temperature. Importantly, it seemed to be especially resistant to change this understanding (Driver, 1989).
