Quantum physics content in a colombian physics textbook

The purpose of this research is to characterise how one of the most widely used physics textbooks in the southwest of Colombia deals with the rupture between classical physics and quantum physics. In order to achieve the proposed objective, a qualitative methodology with a documentary analysis approach was used. As units of analysis, we considered the spaces where the textbook makes explicit content associated with Modern Physics. Two levels of analysis were considered: the content associated with Quantum Theory and the crisis of Classical Physics in the face of the impossibility of explaining some quantum phenomena. The results indicated that the contents addressed in the textbook do not focus on the crisis of Classical Physics. Therefore, it is necessary for Colombian educators who use the book analysed to prepare and develop their classes to appropriate a Quantum Theory that allows them to overcome this limitation.
