Everyday knowledge and scientific knowledge in the interpretation of matter properties
Abstract
This paper presents a study about students’ representations of matter properties. It shows how in order to explain matter discontinuity and intrinsic motion of particles the students frequently use alternative conceptions instead of scientific theories. These conceptions give local consistency centered on the macroscopic perception of matter, while scientific theories give global consistency.
