13. 2021. Un año de incertidumbres para la Educación Matemática
This work describes a methodology to carry out the analysis of technological sectors, using information contained in patent documents. The use of this information by professors and students of chemistry courses and related areas is still little used. The consequence of this is the repetition of efforts to obtain some results of research and development. The
