Modern astronomy as a field of inquiry may be shaped by what we consider the "scientific" ways of knowing. However, the history of astronomy as a human endeavour dates back millennia before the "modern" notions of "science". This long history means that astronomy is, at its core, built on a rich cultural diversity and…

While traditional civic education in the United States is inextricably linked to notions of a public sphere, this paper argues that the digital era requires a reimagining of this premise. The opaque nature of digital spaces makes it difficult for young people to understand how large of an audience they are interacting with and to what extent a…

Silos are an undeniable and unavoidable reality of knowledge production, particularly within academia. For those who choose to navigate between disciplinary boundaries, as opposed to within them, it is not uncommon to find similar concepts developing in parallel in two or more completely different fields of study. These silos tend to be not just…

University students are often asked to learn abstract concepts. Abstract concepts are hard to learn. Giving specific examples can help learning abstract concepts. These examples might limit understanding to the similarities between the abstract domain and particular examples. The primary purpose of this study was to test whether exposure to…

The current entrepreneurial pedagogy focuses on enhancing students' ability in discovering opportunities based on an understanding of users' needs. This study challenges this dominant pedagogy by proposing a method to help students generate innovative ideas and create entrepreneurial opportunities by transforming the existing product's meanings,…

This study explores the integration of multiple sign systems within the English as a Foreign Language (EFL) reading curriculum for undergraduates in Taiwan, addressing varied learning styles that are often overlooked by conventional curricular methods. The purpose is to investigate how incorporating semiotics can enhance learning engagement and…

This article reports on the design and implementation of a didactic sequence in the frame of a design-based research study. The research aim is to test the hypothesis that affordances of dynamic geometry may support students' awareness of logical relationships between geometrical properties of constructed figures. We elaborate on the task design…

Effective learning is viewed as an evolutionary process, and as such, it involves an expanded version of the Crenshaw-Collins view of "intersectionality." It demands an in-depth view of the complex socio-cultural-ethnic milieu in which students are embedded. Even more, effective learning requires effectance problem-solving, investigation…

Previous research suggests that the use of metaphors in science education have both possibilities and challenges. In this study, we analyse the role of metaphors in meaning-making in the upper primary science classroom. We investigate the potential of metaphors about nutrient uptake occurring in classrooms in which an animation was used. To…

Civil engineers and project managers must control and manage the project management discourse with the client and other stakeholders or risk slippages to time, cost, and programs. This paper explores how communicative choices and the representation of project requirements and engineering issues are intrinsic to effective civil engineering work.…

We explored the semiotic choices children in grades 1-6 made that nurtured embodied, dramatizing performances in science classes at urban public schools, serving predominantly students of color in a large US city. We studied how such choices in school and home settings (when instruction was remote during the COVID-19 pandemic) were implicated in…

This article explores how seven Swedish digital teaching platforms in mathematics make use of the affordances provided by various modalities and dynamic functions. A model based on social semiotics is used to analyse how dynamic functions are used, whether or not the language is technically oriented, if relational or operational processes are…

Background: Science teaching and learning, as discursive practices, occur through the utilization of various semiotic modes. Gestures play a pivotal role as an embodied mode that acts in conjunction with speech in oral communication settings, such as classrooms. Previous research on gestures in chemistry and science education has illuminated how…

In vocational education, the learning content is often considered as concrete and specific, and the vocational learning involves physical work and interactions between participants and artefacts. Furthermore, one teacher has the overall responsibility for several students during classes in the vocational workshop at school, which means that the…

This paper describes a Lesson Study in which in-service mathematics secondary-school teachers, collaborating with researchers, involve grade 10 students in tessellation problems. The data are collected by an experiment carried out in the context of the "Liceo Matematico" project, with three volunteer teachers. The experiment goal was to…
