The gather
lesson still needs work. Perhaps one reason this has been tricky is that you need a new dataset for each run through, but the students need to see two or three before they try it on their own. They're just not getting what key
, value
are, how things move, etc. Having them download a single data folder instead of each dataset individually will facilitate this.

Students have been struggling with the arguments to
gather
, especially key and value.
