Abstract
Develop an adequate conception of the nature of science and technology (NOST) is one of the goals of science education. A good conception of NOST is related with how students understand and perceive science concept. Solid state chemistry is one of science concept that has many applications in daily life and advance technology. Unfortunately, this concept is contains abstract concept. Therefore, need an effort to make it easily understood by students. Model of educational reconstruction (MER) is adopted to define learning design in order to make a connection between concept and its applications based on students and scientists conceptions. Students view of NOST is analyzed before and after intervention. Their conceptions about NOST are categorized into realist (R), has merit (HM), and Naive (N). The majority of students held R view of a majority of the target NOST aspects after the intervention. These results showed that learning based on MER could support to develop students conception of NOST.
