From this blog comes an excellent array of questions that challenge the status quo and ask peole to examine their true thoughts about what and how we learn, and why. Examples include the following:
If a question has a correct answer, is it worth asking?
If something is "Googleable" why would we spend precious class time teaching it?
I have added my own questions in the comment section, including questions about why we don't trust students to take charge of their education and if we truly want all students to be educated.
What subversive questions would you add?
