Argumentation, and the production of scientific arguments are critical elements of inquiry that are necessary for helping students become scientifically literate through engaging them in constructing and critiquing ideas. This case study employed a mixed methods research design to examine the development in 5th grade students’ practices of oral and written argumentation from one unit to another over 16 weeks utilizing the science writing heuristic approach. Data sources included five rounds of whole-class discussion focused on group presentations of arguments that (...) occurred over eleven class periods; students’ group writings; interviews with six target students and the teacher; and the researcher’s field notes. The results revealed five salient trends in students’ development of oral and written argumentative practices over time: Students came to use more critique components as they participated in more rounds of whole-class discussion focused on group presentations of arguments; by challenging each other’s arguments, students came to focus on the coherence of the argument and the quality of evidence; students came to use evidence to defend, support, and reject arguments; the quality of students’ writing continuously improved over time; and students connected oral argument skills to written argument skills as they had opportunities to revise their writing after debating and developed awareness of the usefulness of critique from peers. Given the development in oral argumentative practices and the quality of written arguments over time, this study indicates that students’ development of oral and written argumentative practices is positively related to each other. This study suggests that argumentative practices should be framed through both a social and epistemic understanding of argument-utilizing talk and writing as vehicles to create norms of these complex practices.

Scientific reasoning is particularly pertinent to science education since it is closely related to the content and methodologies of science and contributes to scientific literacy. Much of the research in science education investigates the appropriate framework and teaching methods and tools needed to promote students’ ability to reason and evaluate in a scientific way. This paper aims to contribute to an extended understanding of the nature and pedagogical importance of model-based reasoning and to exemplify how using computer simulations can support (...) students’ model-based reasoning. We provide first a background for both scientific reasoning and computer simulations, based on the relevant philosophical views and the related educational discussion. This background suggests that the model-based framework provides an epistemologically valid and pedagogically appropriate basis for teaching scientific reasoning and for helping students develop sounder reasoning and decision-taking abilities and explains how using computer simulations can foster these abilities. We then provide some examples illustrating the use of computer simulations to support model-based reasoning and evaluation activities in the classroom. The examples reflect the procedure and criteria for evaluating models in science and demonstrate the educational advantages of their application in classroom reasoning activities. (shrink)

This chapter aims to revisit the notion of argumentation that is currently used in science education. After acknowledging a consolidated tendency of linguistics-based approaches to the study of ‘school scientific argumentation’, the chapter proposes to shift the interest towards an examination of the epistemic aspects of argumentation, i.e. those that derive from its central participation in science as a process and as a product. The premise of the chapter is that the contributions of the philosophy and history of science and (...) of other science studies and metatheoretical perspectives –which are here collectively called ‘HPS’– constitute a fruitful theoretical background to understand scientific arguments and arguing in educational settings. Based on this premise, five possible ‘bridges’ between argumentation and HPS are proposed; such bridges are identified through a ‘theory-directed’ literature review. (shrink)
