This essay aims to advance the debate on the conceptualization of interdisciplinarity in mathematics education by presenting the idea of the border as a dynamic semiotic cross-cultural space. We refer to three theories, that originate in different research fields and use specific languages: De Luca Picione and Valsiner's idea of the border as a…

The implementation of video modeling examples of mathematical hands-on experimentation may provide students with authentic and, at the same time, not too cognitively overwhelming experiences. However, the effectiveness of video modeling examples can be influenced by different characteristics of the observed models. On the one hand, based on the…

Acquiring mathematical literacy requires students to apply mathematics in various real-world contexts. However, mathematics classes often provide brief, content-focused descriptions of reality-based tasks and tasks that describe the situation as more complex, closer to reality, are still lacking. Students with different sociodemographic…

The teaching of conceptual understanding is a key objective in the field of science education. But students, on average, do not adequately understand the concepts in a large number of science subjects. This is the case with Ethiopia's students as well. Additionally, conventional instruction is the primary method used by Ethiopian school teachers.…

Research in STEM education has focussed on integrated STEM projects that combine knowledge and skills across science, technology, engineering, and mathematics. These integrated STEM projects are typically designed by teachers or researchers addressing a limited range of topics that do not always cater well to the diversity of interest among…
