With increased focus on data literacy and data science education in K-12, little is known about what makes a data set preferable for use by classroom teachers. Given that educational designers often privilege authenticity, the purpose of this study is to examine how teachers use features of data sets to determine their suitability for authentic…

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…

This qualitative study was conducted to understand the instructional strategies used by high school integrated STEM (iSTEM) teachers to apply real-world problem solving in their classrooms in the state of Indiana. The problem addressed by this study was the need to understand the instructional strategies employed by iSTEM teachers in their…

This study investigates the problem-solving strategies employed by ninth-grade students when addressing symbolic and real-world contextual problems involving trigonometric ratios. Conducted with 46 ninth-grade students from a Turkish public high school, this research employed a worksheet consisting of six problems aligned with the Turkish…

In this paper, we continue describing the project and the experimentation of "Ricerca Operativa Applicazioni Reali" (ROAR; in English, Real Applications of Operations Research), a three-year project for higher secondary schools, introduced. ROAR is composed of three teaching units, addressed to Grades 10, 11, and 12, respectively, having…

This study aims to determine to what extent high school students are able to associate their knowledge of acid-base concepts with daily life. A form consisting of six open-ended questions was used to collect data in line with the specified purpose. Case study design, which is one of the qualitative research methods, was preferred as a method.…

To promote scientific literacy in school science, students need to learn key concepts in science, along with the nature of scientific knowledge and how it is generated. Ideally, this learning mirrors authentic scientific inquiry through student engagement in three key epistemic practices: flexibility and creativity, knowledge construction, and…

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…

Work-based learning programs in the United States are designed to prepare adolescents for their first jobs and to develop the soft skills to be successful in in the classroom or the workplace. Historically these programs have neglected how work, education, and training in the local context are connected to issues on national and international…

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…

Programming and automation continue to evolve rapidly and advance the capabilities of science, technology, engineering, and mathematics (STEM) fields. However, physical computing (the integration of programming and interactive physical devices) integrated within biomedical contexts remains an area of limited focus in secondary STEM education…

The use of unsafe water as a source for drinking, cooking, and bathing can lead to serious health complications. Point of Use (POU) water treatment technologies can play an important role in making safe and clean drinking water available to communities. One low-cost, low-technology POU system is the biosand filter (BSF). BSFs offer an effective…

Background: Design problems have long attracted researchers' attention for their potential to provide authentic learning opportunities. While we have methods for supporting students to learn through relatively simple engineering and design tasks, supporting students to address complex problems that they find and frame remains poorly understood.…

With the development of technology and the normalization of COVID-19 pandemic prevention and control, asynchronous online learning is becoming popular. However, it is still to be explored on how to enhance students' learning engagement and knowledge construction. Based on this, we used content analysis to explore the roles of teaching strategies…

We introduce "Ricerca Operativa Applicazioni Reali" (ROAR; in English, "Real Applications of Operations Research"), a three-year project for higher secondary schools. Its main aim is to improve students' interest, motivation, and skills related to Science, Technology, Engineering, and Mathematics disciplines by integrating…
