The Math4Mobile midlets were written in J2ME and squeezed into 128×128 screens and the twelve keys every phone had — so that a student waiting for a bus could explore a function, and send what they did to a teacher. Getting there took a research group, a pedagogical design and months of development.
The idea has not changed. What has changed is what it costs to build one. I described the idea behind Graph2Go to an AI and had it running in ten minutes — an interactive function explorer with fourteen function families:
Ten minutes is a developer’s ten minutes. But the distance between a teacher’s idea and something a class can open is now a fraction of what it was, and it keeps shrinking. I published the explorer on Embeducate.
