There is a consensus that numeracy is important for students to develop logical thinking and reasoning strategies in their everyday activities. As a result, teachers are encouraged to design numeracy rich tasks that incorporate real-life contexts across non-mathematics curriculum areas. However, it is not clear what types of knowledge teachers…

Here, we systematically review research on teaching knowledge in the context of undergraduate STEM education, with particular attention to what this research reveals about knowledge that is important for evidence-based teaching. Evidence-based teaching can improve student outcomes in undergraduate STEM education. However, the enactment of…

This study compared two versions of the same elementary science professional development (PD) and curriculum program that were offered face-to-face and completely online, while keeping all content consistent between the two. Using quantitative analyses of pre- and posttests of content knowledge (CK), we evaluated the extent to which the online…

Agricultural systems are complex and can be used as examples to teach science, technology, engineering, and math (STEM) concepts. However, inclusion of agriculture in core STEM courses is often limited. Three professional development sessions for K-12 teachers were offered in 2021-2022 (hybrid or remote sessions) and repeated in 2022-2023…

In a Swedish second semester course on Euclidean and non-Euclidean geometry in mathematics education at Karlstad University, a bridging teaching strategy comprising elements from Mathematics, Didactics, History, Literature, and Technology was applied by using the concept of Narrative Didactics and Digital Interactive Mathematical Maps developed by…

Situated in the context of an in-service professional development (PD) program focused on Interdisciplinary Science Inquiry, this quantitative study tests the validity of and further explores the theoretical model adapted from Desimone's (2009), "Educational Researcher," 38, 181-199 conceptual framework on effectiveness of PD. The…

An interdisciplinary and pluralistic approach to teaching and learning has been proposed as one solution to the lack of a consensus definition of sustainable development (SD). For teachers, such an approach requires an awareness of the interconnections among different dimensions of SD and their underlying value-based assumptions. In this article,…

Climate change adaptation is a notorious example of a wicked problem. Teachers need to have extensive knowledge to design high-quality education that addresses the wickedness and contributes to wicked problem-solving. The components of the knowledge basis for teaching climate change issues can be highlighted with the Pedagogical Content Knowledge…

Professional knowledge is highlighted as an important prerequisite of both medical doctors and teachers. Based on recent conceptions of professional knowledge in these fields, knowledge can be differentiated within several aspects. However, these knowledge aspects are currently conceptualized differently across different domains and projects.…

Despite elementary teacher education programs preparing preservice teachers in the main content areas of literacy, math, science, and social studies, few elementary school classrooms teach all four content areas on a regular and thorough basis. Therefore, elementary education teacher preparation programs should be redesigned to support an…

The research experience for teachers (RET) professional development was a six-week long summer-intensive National Science Foundation (NSF) funded project that took place at a large university in western Texas. It was designed to provide a research-rich learning environment in data science and cybersecurity for STEM teachers in the region, which is…

Geometry and culture are interrelated, making school geometry closely connected to the environment as well as culture in which it is taught. With regard to this connectedness, the Zimbabwean mathematics syllabus indicates that geometry should be connected to the learners' environment and culture. This article explores teacher-related challenges to…

The purpose of the study is to explore how elementary preservice teachers' mathematics-science integrated teaching strategies changed as a result of participating in exemplary interdisciplinary activities with multiple themes across school curricula. The participating elementary preservice teachers (n = 28) were recruited for this study from the…

The goals of this four-phased study were to enhance the quality of educational experience for under-represented (rural, low income, and female) secondary students (N=628), and to increase their participation in mathematics and science courses beginning at the middle school level. Teachers (N=28) were asked to expand their pedagogical content…

This document presents the proceedings of the 31st Annual Conference of the Mathematics Education Research Group of Australasia (MERGA). The theme of this conference is "Navigating Currents and Charting Directions." The theme reminds us that, although we are constantly pushed to account for the quality and impact of our research, we…
