Aguirre, Jose; Erickson, Gaalen – Journal of Research in Science Teaching, 1984
Presents a logical analysis of three vector concepts (position, displacement, velocity) in terms of their constituent characteristics and shows how they can be used to structure an empirical investigation into students' prior knowledge about these characteristics. Reports results of students' (N=20) conceptions about the vector characteristics…
