With its objective to provide a solution for the needs outlined above, the project outcomes can be seen as an essential contribution to the European Commission's Digital Education Action Plan 2021-2027 (DEAP) which sets out the central objectives for education and training in the digital age in Europe. In particular, it is the Commission’s commitment to foster the development of innovative approaches to online and distance learning esp. in primary and secondary education. Also, the project addressed the European Framework for the Digital Competence of Educators (DigComEdu), which, among its five areas, lists the ability to choose and modify material from OER resources and, notably, to create digital learning material designed for the specific needs of their pupils.
During the pandemic in 2020/21 schools and teachers have understandably turned towards quick and easy solutions for managing the challenge of distance learning, e.g. turning paper material into pdfs for up- and download. This practice has been described as migratory. However, it is the transformative approach that is needed for a genuine digital transformation of educational practices as this means exploring the full potential of the digital media and tools for a meaningful and effective teaching and learning. In the area of mathematics, among the affordances of digital media that evidently lead to a meaningful and effective teaching and learning are multimodality, dynamisation and interactivity, and the use of automated adaptive feedback. With GeoGebra and STACK there are well-known authoring tools for creating digital learning material, each with specific strengths for creating multimodal dynamic and interactive applets or randomized task with adaptive feedback resp. What was missing then was a tool that makes use of the combined potential of both tools in mathematics teaching and learning.
