To enhance student career aspiration involving S&T, relevance of science education, and students’ scientific literacy, industrial site visits and their integrated activities have been attempted since the EU 6th Framework research project (Material Science). However, the previous project has not yet verified its short- and long-term hypothesis. The first hypothesis is that the industrial site visits might shift students’ situational interest into personal interest in S&T. Moreover, the site visits might enhance students’ career aspiration involving S&T, which solves the current issue of decreasing scientists in the EU. Hence, this research project focuses on the module of Material Science, by (1) implementing the foreign instructional materials into Estonian students, (2) examining its influence on students’ career aspiration in S&T, scientific literacy, and relevance of science education before and after the site visits, and (3) estimating the structure of students’ career aspiration by structural equation modeling. The quantitative methods will be employed to enhancement in experimental design. Finally, 2-round Delphi study will examine experts’ opinion on implication of the quantitative findings for context-specific implementation of the industrial site visits in the Estonian curriculum of science education.
