Background: Aphasia is a communication disorder caused by brain damage. People with aphasia (PWA) often experience difficulties in interaction. Methods: This study uses conversation analysis (CA) and examines the interactions of 10 PWA (5 fluent and 5 non-fluent speakers) and their healthcare professionals. Aims: The study aims to to explore how…

The purpose of this study is to identify and analyze meanings that the term "complexity" assumes in Brazilian theses and dissertations in the field of environmental education, especially when addressing socio-environmental issues. The studies were selected from the database Theses and Dissertations of EArte (http://earte.net/), which is…

Children's beliefs about the contribution of effort and ability to success and failure shape their decisions to persist or give up on challenging tasks, with consequences for their academic success. But how do children learn about the concept of "challenge"? Prior work has shown that parents' verbal responses to success and failure shape…

This qualitative study aims to investigate novice undergraduate mathematics students' first encounter with the First Isomorphism Theorem, which is, more often than not, the pinnacle of a typical introductory course in Group Theory. Several studies have reported on the challenges that this mathematical result poses to inexperienced mathematicians,…

This research draws on Legitimation Code Theory (LCT) to understand the epistemic dimension of the higher education classroom discourse of a professor who is well evaluated by his students. In expository science classroom discourse, concepts are loaded with different meanings, a process that is called "condensation of meanings" in LCT,…

Out of school time (OST) STEM opportunities are often presented as ways to support student achievement, understanding, and identity in STEM. Recent work has begun to explore how OST programs function within the STEM Learning Ecosystem, a holistic view of the various STEM learning opportunities available to youth in a given area. In order to…

Purpose: An analysis of the relationship between discourse and cognition in the context of middle school science teaching is provided in this study. Teacher-led questions, cognitive demands and patterns of interaction were analysed for the discourse side of the study. The students' argumentation quality was explored for the cognition side of the…

Purpose: This study sought to 1) identify linguistic features important for Chinese text complexity with a theory-based and systematic approach, and 2) address how feature sets and algorithms affect the performance of Chinese text complexity models. Method: Texts from Chinese language arts textbooks from Grades 1 to 6 (N = 1,478) in Mainland China…

Purpose: The aim of this article is to show the underlying structure of developed argumentations in five role-plays recorded in civic education in a vocational school. Method: Two models were developed to analyse discursive moves and to analyse complexity levels within students' arguments. Findings: The models show the quality of argumentations in…

Narratives skills are associated with long-term academic and social benefits. While students with disabilities often struggle to produce complete and complex narratives, it remains unclear which aspects of narrative language are most indicative of disability. In this study, we examined the association between a variety of narrative contents and…

Background: How teachers enact policy has been of significant interest to educational scholars. In physical education research, scholars have identified several factors affecting the enactment of policy. These factors include but are not limited to: structural support available for teachers, provision of professional development opportunities, the…

This paper analyzes the discursive activity of an upper secondary school teacher on the topic of the derivative. Specifically, we focus on the discursive activity when introducing the three essential concepts related to this topic: the average rate of change, the derivative at a point, and the derivative function. The theoretical framework used is…

Educators' support when using informational text in kindergarten is foundational to children's comprehension and future learning. Prior research has not offered clear insight into their help when children experience difficulties during informational text comprehension instruction. The current study examined one kindergarten educator's support.…

Negative sentences are hard to process when they are presented out of context. When embedded in a context of plausible denial their processing difficulty decreases or is completely eliminated. We investigated in six behavioral experiments whether the processing of negation is eased in a denial context triggered by discourse markers (e.g.…

This paper presents the findings from a survey used to investigate how mathematicians perceive the genre of mathematical proof writing at the undergraduate level. Mathematicians were asked whether various proof excerpts highlighted in four partial proofs were unconventional in each one of three pedagogical contexts: undergraduate mathematics…
