GeoGebra AR in Cooperative Settings
摘要
How can GeoGebra AR in collaborative settings provide insights into learners’ spatial reasoning and use of tools? This paper addresses this question by considering three studies (Bachelor & Master theses), each approaching this topic with its own perspective regarding the variety of mathematical objects in AR settings, the use of tools, and heterogeneity. Accordingly, a rather broad theoretical background of the levels of spatial reasoning, tools, and cooperation is explained at first to frame the three studies. After that a more detailed description of the studies is given. Finally, the similarities of the studies are identified, and common research findings are formulated as well as an outlook pointing to opportunities in research methodology in mathematics educational research on AR technology.
