This video shows how a triangular diagram is created to place the various models in an objective way.
The models located at the base of the triangle would be coherent with respect to the underlying reference system (geocentric on the left and heliocentric on the right). At the top vertex it places an incoherent mixed model. If in this model (in which both the plane and the Earth move) it was clarified that the reference system would always be located at an intermediate point (that is, in motion), this mixed model would be located in the center from the base.
At the end, the set of 24 submodels identified during the intervention is shown (which shows the richness of ideas that were provoked), as well as the evolution of the students' ideas (represented by colored arrows with the initial letter) during the intervention.
