Resumen: [EN] The present work analyzes the relavance of using video for promoting
reflection about chemical contents and their learning, in the context of the
Spanish Master’s in Secondary Education. The used video clips were edited
from the recordings of two cooperative groups of Master’s students who were
solving an open-ended problem about chemistry. This problem was stated as
follows: «What might happen when two substances are placed into contact
with each other?» These clips contained some alternative conceptions in
chemistry, together with some theoretical and practical difficulties arisen in
the solving process. Later, the video was shown in the framework of a focus
group, where a free debate between the participants was stimulated. The
transcriptions of this session gave rise to a group of categories of analysis
related to different stages of problem resolution, and emotional aspects as
well. These results make us conclude that using video is an appropriate way
of promoting learning about physical and chemical changes through
cognitive conflict. Moreover, the necessity of considering emotional,
individual and group aspects in conceptual change is supported.
