Mathematical ideas are developed and spread during argumentative whole class discussions between a teacher and her students. The goal of the current study is to characterize how ideas about quadratic functions emerge and are spread during a whole-class discussion among ninth graders. To this end, we recorded both discussions between pairs of…

This paper aims to shed light on an overlooked but essential aspect of informal reasoning and its radical implication to mathematics education research: Decentralising mathematics. We start to problematise that previous studies on informal reasoning implicitly overfocus on what students infer. Based on Walton's distinction between reasoning and…

In our ever-changing and complex world, we encounter difficult problems that demand sophisticated solutions. Critical thinking, a vital skill for modern survival, lies at the heart of higher education. It is what we should develop in students, arguably a concept that defines higher education. Critical thinking, however, is subject to wide…

Argumentation-based classroom interventions are a growing alternative for stimulating conceptual learning, thinking, and communicative skills. However, not all classroom argumentation is desired, nor does every argumentation design lead students to develop their abilities and understanding. In the educational literature, productive argumentation…

Preservice teachers (PSTs) are expected to possess a relational understanding (i.e., knowing how to do and why) of mathematics for ambitious instruction. This study aimed to shed some light on the possibilities of supporting PSTs' development of relational understanding of fractions through engaging them in writing collective argumentation.…

Despite considerable progress made in educational neuroscience, neuromyths persist in the teaching profession, hampering translational endeavors. The initial wave of interventions designed to dispel educational neuromyths was predominantly directed at preservice teachers. More recent work in the field, reviewed here, has shifted its focus…

This study used a case study, one of the qualitative research methods, with the aim of developing guidance materials based on the argumentation-based science learning (ABSL) approach for concepts in the 6th grade unit "Sound and Its Properties" and to examine students' argumentation levels and conceptual understanding. The activity…

Scientific misconceptions are ubiquitous, and in our era of near-instant information exchange, this can be problematic for both public health and the public understanding of scientific topics. Refutation text is one instructional tool for addressing misconceptions and is simple to implement at little cost. We conducted a random-effects…

Argumentation plays a central role in the development and justification of scientific knowledge. Learners could attain a more scientifically acceptable conceptual understanding by attending argumentation-based discussions. During argumentation-based discussions, students need to activate some metacognitive processes related to concept learning,…

Belief in psychological misconceptions, especially those regarding brain function and learning (i.e., neuromyths), hinders students' decision-making and learning. This necessitates conceptual change. Using an experimental design, this dissertation examined whether a utility value instructional induction (UVII) facilitated conceptual change.…

The authors developed an instructional nudges as part of a larger research project. These instructional nudges are designed to be small but powerful changes to teachers' existing practices. Some instructional nudges focus on modifying tasks used in classrooms. In this article, the authors share Rate and Review. The goal of Rate and Review is to…

Meaningful learning for conceptual change in science education should aim to help students change their existing misconceptions to develop an accurate understanding of scientific concepts. Although collaborative argumentation is assumed to support such processes, its value for conceptual change is unclear. Moreover, the roles of argumentative…

The study investigated the influence of a connected learning approach for explicit nature of science (NOS) instruction and explicit argumentation instruction, in comparison with a non-connected approach, on students' NOS conceptions and argumentation skills. Participants comprised 42 students enrolled in two sections of grade 10 that were randomly…

Refutation texts are resurfacing as a suggested antidote to misconceptions and "fake news." In a previous critical review of the refutation text literature, we, the author team, suggested further interrogation of the assumptions these texts imply: that learners share the same common misunderstanding about a topic, and that there is one…

This book aims to advance ongoing debates in the field of mathematics and mathematics education regarding conceptions of argumentation, justification, and proof and the consequences for research and practice when applying particular conceptions of each construct. Through analyses of classroom practice across grade levels using different lenses -…
