There is no consensus in science and research, regarding representational competence (RC) as a unified theoretical framework. RC is essential for the acquisition of conceptual understanding in physics. It enables the interpretation of diagrams, graphs, and mathematical equations, and relating these to one another as well as to observations and experimental outcomes;
success in solving physics problems is related to the representational format of the problem. In this sense, Alwielland Q. Bello RC can indeed be understood as the competence to mentally represent a physics problem or generally physics theories by simple cognitive models, mainly via visualization (simple model by combining simple human language, logic and math).
A theory
has, only the alternative
of being right or wrong.
A model has a third possibility: it
may be right, but irrelevant.
Manfred Eigen
All models are approximations. Essentially, all models are
wrong, but some are useful. However, the approximate nature of the model must always be borne in mind.
