Twenty-first-century competencies and mathematical literacy have many overlapping features. Although mathematical literacy is one of the necessary components to create 21st-century skills, each individual needs to understand mathematical literacy to solve the problems encountered in daily life. This study examined the effects of pre-service…

This study was performed to determine preservice elementary mathematics teachers' solution performance of systems of linear equations using geometric representation, algebraic representation and transition from geometric representation to the algebraic representation and the predictive role of preservice elementary mathematics teachers'…

Students enter the science, technology, engineering, and mathematics (STEM) pipeline in primary school, but leak out of it over time for various reasons. To prevent leaks, it is important to understand the variables that affect attitudes towards STEM learning from an early age. This study sought to examine the predictors of young students' STEM…

An issue arising in emergency distance education procedures, such as the response to the COVID-19 pandemic, is a lack of appropriate high-quality content and course activities for high ability students suitable for distance education. In this study, online CAD-based learning experiences structured with the Tinkercad Circuits Platform designed for…
