This paper introduces the term "explorative mathematical argumentation" (EMA), signifying a concept for describing and analysing learners' mathematical argumentation processes. Despite multiple recent empirical evidence for argumentation promoting learning in science education, still little is known about the development of early…

Argumentation is a fundamental communicative ability that children develop over time through formal schooling and daily practice with peers and family members. Literature on children's argumentation appears to have focused on their social interactions out of school, clinical environment, or informal pedagogic contexts. Even though there are…

We describe how mathematical argumentation supports curiosity and exploration by sharing a first-grade lesson in which students explored decomposition with subtraction. We also reflect on the conditions that supported the inclusion of mathematical argumentation.

In this article, the authors share the story of Diego, a kindergarten student, navigating issues of mathematical identity and competence--his own and those of his kindergarten classmates. The authors are a team of educators, including a kindergarten teacher (Sara) and a math teacher educator (Jody) who worked together on a quality improvement…

Given the need to educate future critical thinkers, it is necessary to explore preschool teachers' level of argumentation about socioscientific issues in order to facilitate their use of appropriate strategies for effective argumentation in their own classrooms. To achieve this aim, it is also necessary to propose the use of a set of previously…

Understanding how young learners come to construct viable mathematical arguments about general claims is a critical objective in early algebra research. The qualitative study reported here characterizes empirically developed progressions in Grades K-1 students' thinking about parity arguments for sums of evens and odds, as well as underlying…

The paper reports how a teacher and her students use drawings as a resource for observations and how such observations are connected to different epistemic practices in science lessons. Interactional data in a 1st grade classroom were analyzed based on Ethnography in Education. Results show that the use of drawings materialized children's…

In this article, the author examines how the New York State Social Studies Resource Toolkit supports argument discourse in social studies and then explores a primary teacher's curricular and instructional decisions regarding the development of children's argumentation skills. The study provides insights into how teachers can involve some of our…

Conversation circles in kindergartens can foster discursive abilities such as argumentation. This paper analyzes argumentation in conversation circles in a kindergarten with respect to the function of narrative argumentation. We focus on second stories as a specific narrative form that is characterized by relating in content and form to a before…

Building students' confidence and conceptual understanding early sets a solid foundation for reasoning and exploration. "Nurturing Math Curiosity With Learners in Grades K-2" offers educational tools and strategies teachers can use to integrate mathematical argumentation in early elementary classrooms, allowing space for students'…

This article discusses classroom conditions that support the co-creation of dialogic space--where our different ideas and perspectives are in conversation with others such that we might take in what other people are saying and be open to it affecting our thinking. Drawing on ethnographic case study data, we provide context to illustrate ways this…

Diverse children's literature can support understandings of our world as culturally, linguistically, and socially rich. It can cultivate empathy and understanding, and open a dialogic space of possibilities. In this article, we examine how "purposefully selected" children's literature prepares needed conditions for dialogic space:…

Argumentation, a key scientific practice presented in the "Framework for K-12 Science Education," requires students to construct and critique arguments, but timely evaluation of arguments in large-scale classrooms is challenging. Recent work has shown the potential of automated scoring systems for open response assessments, leveraging…

Second-graders engaged in complex reading, writing, and thinking about Rosa Parks and the Montgomery Bus Boycott. Close readings of secondary and primary sources situated students to discover incongruencies between what is reported within trade-books and what is revealed within historical documents. Scaffolding directed students' scrutiny of…

Becoming proficient in scientific discourse such as argumentation or developing explanations can be challenging for students, including neurodivergent students (e.g., autistic students, students with learning disabilities, students with ADHD). Students need to practice developing arguments and explanations as well as sharing their conclusions with…
