In this article, we investigate the effects of the app "Fingu" on a child's understanding of the part-whole concept. Using the Artifact Centric Activity Theory framework, we initially analyse the internalisation and externalisation processes that appear to occur during one child's use of the app. Based on the learning from this process,…

While GeoGebra applets have been extensively investigated in learning environments, few studies have addressed the interactive GeoGebra applets in an e-book-based learning environment. This study aims to compare the effects of the e-book created with interactive GeoGebra applets on students' learning achievement and motivation. The sample of the…

This study aims to explain the Metaverse application development process for teaching geometry in a virtual reality environment. The application was developed based on the instructional design model including analysis, design, development, implementation and evaluation phases. The target group was secondary school students. During the analysis…

Digital multi-representation applets offer promising opportunities for promoting students' conceptual understanding by dynamically converting graphical and symbolic representations and for promoting discoveries and justifications of mathematical properties. However, learning effects of open-ended multi-representation applets seem to depend on…

In university education, lecturers often adopt didactic lectures in undergraduate calculus classes. This method has been judged for making students passive recipients of calculus knowledge who cannot construct their own knowledge of the discipline. One way to make didactic lecture more interactive and engaging in calculus class is to encourage…

The usage of digital media, especially tablet apps, is currently a major concern in educational settings. A controversial discussion is also taking place in relation to mathematics education at primary schools. While on the one hand there are empirical findings on helpful isolated examples and related subject-didactic potentials of digital media,…

Studying and solving geometry questions are the most challenging parts of mathematics for visually impaired students (VIS). This study begins with the needs assessment to identify the needs of VIS, which shows that technology-assisted effective teaching and learning are not available for VIS to learn geometry. Therefore, this study focuses on…

In this paper, we examine learning experiences of 11 students in Ghana who were taught mathematics in the English language high school system and who thereafter did not attain the pass mark in their national final mathematics exam. They however went on to pass this exam after using an app that teaches mathematics in Ghanaian languages. We view our…

In recent years, studies have discussed how to introduce computational thinking (CT) concepts in mathematics education through mobile app development. In this study, the design of mathematics lessons based on the 5E instructional model to extend the idea of CT in a mobile technology environment (i.e., mobile CT) was investigated. Twenty-three…
