The absence of science-technology-society (STS) interactions and its c
onsequences in the basic teaching of science in Spain are analyzed in
the first part of this work. This article proposes the introduction of
STS interactions in physics and chemistry classes in conjunction with
the teaching/learning model of science as research. When such interac
tions are not introduced, it can be observed that the students have a
vision of science that is removed from the world in which they live an
d are unfamiliar with the mutual relationships between science, techno
logy and the natural, social environments in which they are immersed.
Not only do a large number of textbooks fail to cover STS interactions
, but the majority of teachers do not consider interactive STS aspects
necessary, nor do they contemplate these aspects in instruction. All
of this contributes to the lack of students' interest in physics and c
hemistry and their rejection of them as subjects. In the second part o
f the work, students of 16-18 years of age in the last 3 years of seco
ndary education were surveyed, and the results obtained were analyzed.
These results confirmed that dealing with STS interactions in the cla
ssroom established science as something alive, more complete and integ
rated in the students' environment. Students subsequently developed an
improved comprehension and a more real image of these sciences, which
allowed them to understand better the role of scientists and how they
work. All of this generated positive attitudes toward the study of ph
ysics and chemistry and increased the students' interest in their stud
y. Thus the results of this research make it clear that it is possible
to transform the learning of physics and chemistry with the inclusion
of STS activities, so that the students can build scientific knowledg
e. Likewise, students integrate essential aspects that affect the scie
ntific activity and contribute to deepening and consolidating their ow
n knowledge. (C) 1997 John Wiley & Sons, Inc.
