So, the challenge is to create and propose instructional sequences that serve simultaneously to the teachers’ learning process
and as a possible suggestion of teaching process for them to develop with their students. Activities that, by avoiding the model in
which contents are reproduced and transferred, can provide teachers with meaningful learning, regarding both the conceptual
questions involved and the teaching methodology used. Therefore, having an enlarged knowledge on specific conceptual aspects,
teachers can develop a more autonomous attitude towards the content selection and organization. And, if what they experienced as
novices in an instructional sequence was shown to be effective and relevant, it increases their methodological repertoires and their
possibilities to make a proper choice regarding their teaching procedures. (p. 64).
