A course which personalizes authentic math learning for each individual learner
Yes, I see what you mean. Definitely the way to go for courses which support different contexts.
I'm wondering if we need a fully separate course...learning pathway....for people using different spreadsheet software, at least for the very basic stuff. As we get into it, we'll have to see if there are situations which would make sense for the learner to choose activity directions or screenshots specific to the software they are using, and then that bit gets transcluded into the page. This method would only make sense if it's more common than different.
I haven't used Excel in quite some time, so I'm not sure how different the learning content will need to be.
