Critical Thinking and Epistemic Sophistication in Science Education.

One of the central purposes of education at different educational levels is to contribute to the formation of critical thinking in students. There are many theoretical perspectives from which critical thinking is conceptualized, such as those centers on the development of students' capacities and those based on competences, skills, dispositions and criteria, among others. We consider that in the school context the critical thinking perspective that should come first is the domain-specific one; consequently, we present a conceptual model for the formation of critical thinking in the context of science teaching and learning in the classroom constituted by the integration of four dimensions: languages and argumentation, metacognition, emotions, and problem solving and decision making. Our focus of reflection is epistemic cognition with the processes of epistemic sophistication, metacognitive sophistication, and metaemotional sophistication, determinants of critical thinking in relation to each of the dimensions and the relationships between them. We conclude with the proposal of a conceptual model for the development of critical thinking based on students' epistemic cognition.
