It is important to understand how students reason in K-12 integrated STEM settings to better prepare teachers to engage their students in integrated STEM tasks. To understand the reasoning that occurs in these settings, we used the lens of collective argumentation, specifically attending to the types of warrants elementary students and their…

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)…

At the 2015 "NARST: A Worldwide Organization for Improving Science Teaching and Learning Through Research" Annual International Conference, a group of scholars held an extended pre-conference workshop to discuss key challenges and future directions faced by argumentation researchers around the world. This wide-ranging group of…

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…

In this exploratory case study, we consider how students in an undergraduate biochemistry class engaged in the process of argumentation within an inquiry-oriented learning environment to investigate a chemical mechanism in a particular part of the tricarboxylic acid cycle. Audio/video recordings of student groups during the mechanism discussion…

Fifty-seven students in mathematical content and secondary mathematics methods courses from four U.S. universities participated in an instructional sequence to generate communal criteria defining mathematical proof within their respective classrooms. Participants completed a proof-related task before class, worked together in small groups to…

The present study explores reasoning and argumentation in Greek mathematics and physics texts in specific topics related to the notion of periodicity. In our study, argumentation is taken as the sequence of the modes of reasoning (MsoR) that an author develops in a text when organizing and presenting new knowledge. Inductive content analysis was…

In a society which is calling for more productive modes of collaboration to address increasingly complex scientific and social issues, greater involvement of students in dialogue, and increased emphasis on collaborative discourse and argumentation, become essential modes of engagement and learning. This paper investigates the effects of…

Bias is part of the human condition and becoming aware of how to avoid bias will help to ensure greater accuracy in the work of assessment. In this paper the authors discuss three different theoretical frameworks that can be applied when assessing student work for cognitive skills such as critical thinking and problem solving. Each of the…

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'…

This study examines the verbal interactions among a group of pre-service teachers as they engaged in scientific discussions in a medicinal chemistry course. These discussions were part of the course that encompassed an explicit instruction of scientific argumentation structures as well as an applied component, whereby the pre-service teachers…

With the rapid advancements of technology, online communication in both K-12 and post-secondary instruction has been widely implemented. Instructors as well as researchers have used various frameworks to evaluate different aspects of online discussions' quality. The online discussions take place synchronously or asynchronously in chat rooms,…

This study sought to investigate the arguments that ecologists engage in as part of their work and to compare their arguments with the way in which ecological arguments have been presented in school argumentation tasks. Ten ecologists, in subfields ranging from individual/behavioral ecology to global ecology, participated in semistructured…

In this study, I present a qualitative analysis of 11 writing portfolios drawn from a yearlong instructional program designed to apprentice students into the practices of argumentative writing typical of early-college coursework in the United States. The students' formal and informal writings were parsed into utterances and coded along two…

We present our design for a cell biology course to integrate content with scientific practices, specifically data interpretation and model-based reasoning. A 2-year research project within this course allowed us to understand how students interpret authentic biological data in this setting. Through analysis of written work, we measured the extent…
