I think it serves its purpose, which is to create a field against which learning can be starkly seen, and it does it lightly and simply. It's something we can use as shorthand througout the rest of the year, when people say "Will there be days they don't learn anything?" and we can say "July 24."
This: "I think it serves its purpose, which is to create a field against which learning can be starkly seen" was so spot on for me. When I first heard about Learn Nothing Day, I was still very new to unschooling. I was uncertain that all learning was equally important, and I was still dividing life into "subjects"—lots of deschooling was still needed.
I told my kids and they told me quite certainly that it would be impossible to go a whole day without learning. But we tried it anyway. And I saw SO MUCH MORE learning happen because I was watching so closely. It was like a big curtain was lifted that had been preventing me from seeing clearly. When I think back today about that moment, it feels like THAT was the real beginning of unschooling for me. It still feels electric in my memory—all the connections I made that day about learning and its value to the learner within the place and time it is learned. I am so grateful for Learn Nothing Day.
