Obedience is only one thing you could practice...

We become something through practice. We become a weaver by practicing weaving. We become a cook by practicing cooking. We become data analysis experts by working through large data sets in Excel. 

At the public high school I went to, we practiced impressing the teacher, doing things on time, following directions, and performing well at the agenda presented to us, regardless of passion for the content. 

Paolo Friere and bell hooks advocated for education as the practice of freedom. They advocated for a pedagogy in which the content, the layout of the chairs, the way that knowledge was constructed, and, yes, what students did all were part of that practice.

Which begs the question, who do you want to practice becoming? Not to mention, who do you want your kids to practice becoming?
