These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science.
5 Φεβ 2020 · In our development of the Solar System LP, we examined how students' thinking shifted along the dimensions of physical properties, dynamical properties, the formation model, and gravity. As a result, we drew on Wilson's ( 2009 ) construct maps as an organizational structure.
