摘要：In this work it is both discussed and provided a framework of specific competences that may serve as a guide for setting up an ongoing process in the professional development of Science, Technology and Mathematics (STEM) teachers. The fundamentals of the TPACK model serve to base the theoretical background of this scheme, to which we have incorporated an additional feature which means to consider the linguistic (L) dimension, thus transforming it into the TPACLK model. The different detailed professional STEM capacities have been classified into six main sections. The two first points discussed establish the STEM disciplinary and didactic capacities; the third section corresponds to the role of language in the STEM classroom; the fourth category is focused on the motivational elements of the teaching and learning process; the fifth corresponds to the self-perception of teachers and the last section summarises how to integrate effectively the information and communication technologies into the educational STEM activity. This professional development is framed within innovative and research educational activities.
