- Specularity in Algebra
- Experiencing Equivalence, but Organizing Order
- Examples, A Missing Link
- Moore and Less!
I guess it is fair to say that I started my research as a phenomenographer. In my first papers which were mostly about the notion of equivalence, there were always a few lines about phenomenography. Gradually, the research areas that I worked on increased and my explicit reference to phenomenography decreased to zero. However, it seems that it was always with me in whatever I did. I’ve always believed in certain principles, that, any phenomenon can be understood (experienced) in different (though limited numbers of) ways, that, the way someone understands something is somehow related to the way (s)he uses it. And finally something of different nature but decisive in my research is the wish of helping learners to learn better and not just showing where they fail.
