Hacia la concreción de un modelo de perfil profesional básico del profesorado de Ciencias, Tecnología y Matemáticas (CTEM)

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.
