This article aims to illustrate how the collective resolution of routine mathematical tasks can give rise to uncertainties, fostering and supporting a rich and authentic mathematical activity. While solving routine tasks may not typically be classified as problem-solving, the research presented in this paper shows that, at the collective level,…

We explore the responses of 26 prospective elementary-school teachers to the claim "1/6.5 is not a fraction" asserted by a hypothetical classroom student. The data comprise scripted dialogues that depict how the participants envisioned a classroom discussion of this claim to evolve, as well as an accompanying commentary where they…

Uncertainty is a key feature of philosophising with children. It is central to the theory and methodology of philosophical inquiry and the educational assumptions underlying it. Uncertainty also presents a specific challenge for pupils and teachers undertaking philosophical inquiry in the classroom, because mainstream education is mostly based on…

Background: Dealing with uncertainties is inherent in the engineering design process and often poses challenges for young learners. This necessitates providing learners with adequate support to navigate their uncertainties effectively. However, achieving this requires a deeper understanding of the factors influencing learners' uncertainty…

Estimating and accounting for statistical uncertainty have become essential in today's information age, and crucial for cultivating a sound decision making citizenry. Engaging with statistical uncertainty early on can support the gradual development of uncertainty-related considerations that are often challenging to foster at any age. Statistical…

Although the notion of "assumptions" is important in mathematical activity as early as the elementary school, there is limited research on how to help elementary teachers develop "mathematical knowledge for teaching" related to assumptions. In this paper, we discuss the theoretical foundation and implementation of an…

Education plays a crucial role in addressing the climate crisis, with textbooks serving as influential vehicles for shaping societal perspectives and students' competencies. However, in Colombia as in many countries worldwide, no prior research has delved into the portrayal of climate change in school textbooks. In this study, we analyze 41…

There is a considerable amount of research on the nature and effectiveness of modeling as applied to student learning in science. However, few studies have examined the role of students' epistemic uncertainty in modeling and how teachers collaborate with students to recognize and utilize it as a pedagogical resource to support productive struggle…

This predominantly conceptual paper explores "uncertainty": it foregrounds students engaged with climate change, in all its socio-political and more-than-human complexity, as political subjects within and beyond the school. It combines conceptual work on Rancièrian political philosophy with empirical work on teaching climate change in a…

Young children excel at pragmatic inferences known as ad hoc quantity implicatures: they can infer, for example, that a speaker who said "the card with apples" meant the card with "nothing but" apples. However, it is not known whether children take into account the speaker's perspective in deriving such inferences, as adults…

Science teachers usually view students' uncertainty as a barrier to overcome, a negative experience to be avoided, a deficiency in need of remedy. Building on the theory of deep learning in science as a generative and sensemaking process, the purpose of this design-based study is to identify tactics for teachers to manage their students' epistemic…

This brief summary describes a thesis that explores the under-researched subject of pedagogical strategies educators employ to teach about complex sustainability challenges such as climate change to upper primary school children who are increasingly confronted with these issues, both in and out of the classroom. The study focuses on the…

On the occasion of its sesquicentenary, which coincides with an extended period of school closures imposed due to the effects of a global virus pandemic, this paper analyses the Elementary Education Act of 1870, and in particular in relation to its implications for compulsory attendance at school. It did not introduce compulsory schooling but…

This longitudinal case study explores how students' epistemic uncertainty in argumentation can be adapted as a resource to develop knowledge in a fifth-grade classroom. Major data sources include 12 videotaped whole-class discussions focused on group presentation of arguments to obtain peers' critiques across two course units, the ecosystem and…

This study sought to provide an understanding of the sources of work intensification and its effects on assistant principals in Turkey, and the coping strategies they use. The participants of this qualitative study were a sample of 18 assistant principals. The current qualitative study was based on semi-structured interviews. Data analysis was…
