Samenvatting

A goal of science education is for students to develop scientific literacy. Scientific literacy involves the acquisition of factual scientific knowledge and the ability to assess the credibility of scientific assertation. Furthermore, students should be able to include ethical considerations. Realising this goal is complicated because it requires the development of argumentation skills, content knowledge, and an understanding of Nature of Science. Teachers struggle to apply effective strategies in the classroom. Few studies have shed light on usable, effective strategies. Therefore, the research goal is to identify features that encourage students to explore socio-scientific issues. To stimulate the development of scientific literary and support teachers, a web-based educational instrument was designed. In this study, the effects and influences of its features in the context of socio-scientific issues are investigated. The instrument provides a sequence of concept cartoons alternated with an interactive diagram. The instrument is deployed in 14 classrooms in both primary and secondary schools. In this paper, we present the educational instrument and report on its practical implementation and its constituent features. The results indicate that students show active involvement during their interaction with the instrument and reveal both the merits and challenges regarding the various features.
