Integrating PSE in science teaching and learning may support students to learn science
through ethical decision making, and helps them engage in considering the relationship between
science, technology and society. The integration of PSE in science education seeks to
produce a scientifically literate person, based on Thai values. Yuenyong (2009) reports enhancing
science teachers’ capability to teach science by considering the nature of science, and
the relationship between science, technology and society through an STS approach based on
the philosophy of a sufficiency economy. Participating teachers taught physics through an STS
approach in order to support their students to make decision based on the philosophy of a sufficiency
economy. This research suggested that students’ decision making based on PSE enhanced
their self-immunity, and desirable characteristics of living in society of science and
technology.
