The Science, Technology
and Society Series
STS is an international science education movement. It
represents the first significant change in the science curriculum
in 25 years. The STS concept strives to broaden the scope of
science education by integrating into science curricula accurate
presentations of the nature of science, the nature of technology
and the interactions of science and technology with each other
and society. The video series provides illustrative examples of the
relationships between science, technology and society.
The STS connections describe products and processes;
environmental and ethical issues relating to the interrelation-
ships among science, technology and society; how scientific
knowledge develops and the influence of society on scientific and
technological research; and science and technology related
careers. The contexts are meant to be relevant to students* fives
and also prepare students for fife in a r apidly changing society
in which science and technology play an important role.
