The purpose of the paper is to present the framework and design of modules aiming to teach socio-scientific issues and the related pedagogy to pre-service teachers. Specifically, the work presented in this paper is part of the PreSEES project, a Comenius/LLP project with the main aim of engaging elementary and secondary pre-service teachers in critical discussions of everyday science through socio-scientific issues (SSI) and prepare them to teach SSI. We first present the aims of our project, and a framework designed around learning to teach SSI, including pedagogical and theoretical aspects concerning teaching SSI. Finally we present three modules that were designed based on the framework aiming to present these guidelines to pre-service teachers (primary and secondary). The emphasis of the modules is on presenting pedagogical issues related to SSI, with an emphasis on the nature of SSI issues, and pedagogical implications of teaching and assessing SSI. The aforementioned issues are presented in various contexts, such as global warming and edible insects.
