In this report of an action research study, the authors describe how one elementary science teacher educator used transcript coding of simulated classroom discussions as a pedagogical approach to learn about her elementary preservice teachers' (PSTs') abilities to notice key aspects of scientific argumentation discussions. Elementary PSTs (n = 19)…

Many classroom units and lessons are now organized around engaging students in developing claims and evidence. An aspect of teachers' work that is understudied is how teachers manage the complexity inherent in navigating between claims and empirical data. In other words, what do teachers do when students do not see what they are "supposed…

The study is part of a larger project concerned with addressing the problem that Eritrean science teachers face in their attempt to implement a new learner-centred science curriculum. Specifically, the study attempted to determine the effects of the use of an Argumentation-Based Instructional Model (ABIM) on 25 pre-service science teachers'…

Argumentation has been a prominent concern in science education research and a common goal in science curriculum in many countries over the past decade. With reference to this goal, policy documents burden responsibilities on science teachers, such as involving students in dialogues and being guides in students' spoken or written argumentation.…

Background: Despite a growing body of research and curriculum reforms including socioscientific issues (SSI) across the world, how preservice science teachers (PST) or in-service science teachers can teach SSI in science classrooms needs further inquiry. Purpose: The purpose of this study is to describe the abilities of PSTs to teach SSI in middle…

This article focuses on the use of Toulmin's argumentation scheme to investigate the characteristics of student group argumentation in Peer-Led Guided Inquiry sessions for a General Chemistry I course. A coding scheme based on Toulmin's [Toulmin [1958] "The uses of argument." Cambridge: Cambridge University Press] argumentation…

This study examines how the use of a science inquiry activity in an environmental socio-scientific issue (SSI) impacts pre-service teachers' argumentative practice in two ways: social negotiation and epistemic understanding of arguments. Twenty pre-service science teachers participated in this study as a part of their science methods class. Small…

Since the late 1990s, there has been consensus among educational researchers that argumentation should play a central role in science education. Although there has been extensive relevant research, it is not clear enough how oral argumentation spontaneously occurs in science teaching. This is particularly important with regard to the empirical…

In argumentative discourse, there are two kinds of activity--dispute and deliberation--that depend on the argumentative task goal. In dispute the goal is to defend a conclusion by undermining alternatives, whereas in deliberation the goal is to arrive at a conclusion by contrasting alternatives. In this study, we examine the impact of these tasks…

Multilingual students, multidialectal students, and students learning English as an additional language constitute a substantial and growing demographic in the United States. But these groups of students tend to receive unequal access to and inadequate instruction in Science, Technology, Engineering, Arts, and Mathematics (STEAM), with their…

In this paper we explore the relationship between learning gains, measured through pre-assessment and post-assessment, and engagement in scientific argumentation. In order to do so, this paper examines group discourse and individual learning during the implementation of NASA Classroom of the Future's BioBLAST![R] (BB) software program in a high…
