DiScoro was invited to Iceland as keynote speaker at a conference. The audience consisted of twenty researchers from seven different countries. They research mathematics textbooks and how teachers work with these resources. My speech was about:
How do publishing houses evolve from paper-based mathematics textbooks to digital books?
What are the options when you design digital media?
What are the possibilities when you use digitale media?
What are the demands that come up in: taskformat, hints and feedback?
What are the challenges for authors and researchers?
