152 George Gadanidis ways in which computers can change learning. He had pursued mathematical research at Cambridge University and then worked with Jean Piaget at the University of Geneva, and these combining influences led him to consider using mathematics and computers in the service of understanding how children learn and think. As Papert once remarked, “I was really looking at computers as a way to understand the mind. But at MIT, my mind was blown by having a whole computer to myself for as long as I liked. I felt a surge of intellectual power through access to this computer, and I started thinking about what this could mean for kids and the way they learn. That’s when we developed the computer programming language for kids, Logo.” Papert designed Logo to have a low floor (where kids can engage with minimal prerequisite knowledge) and a high ceiling (where they are free to investigate complex relationships and representations). Over the last dozen years, along with my research collaborators and graduate students in Canada and in Brazil, we have taken up this idea seriously and have been working to develop low floor/high ceiling (LF/HC) access to important math ideas such as infinity and limit, circular functions, linear functions, binomial theorem, non-Euclidean geometry, and group theory, for as young as grade one. We also stretched LF/HC perspective by interviewing mathematicians on these themes. We asked mathematicians to engage in the same sorts of activities as kids did in classrooms, and then we had the mathematicians discuss these ideas further. The idea for interviewing mathematicians in this way grew from my work on the Fields Institute’s “Windows into Elementary Mathematics Project,” whereby prominent mathematicians were invited to discuss topics from elementary mathematics—for instance, Ken Davidson (Waterloo) discussed insights into mathematical proof;
