Ability | Missing | Inadequate | Needs improvement | Adequate | |
A2 | Is able to construct new representations from previous representations | No attempt is made to construct a different representation. | Representations are attempted, but use of incorrect information or the representation does not agree with the information used. For example, showing double-sided/single-sided spectra in place of single-sided/double-sided spectra OR sinusoidal/complex exponential in place of complex exponential | Representations are created without mistakes, but there is information missing, i.e., units, labeling in the graphical representation | Representations are constructed with all given (or understood) information and contain no major flaws |
