Well, obviously, the problem isn’t the “screwing up”, it’s that the teacher was caught, so you make that more difficult. In this case, the Kearney school district has decided to ban tape recorders in the classroom. That sounds smart.
It makes me wonder how many teachers other than David Paszkiewicz are peddling ignorant cant in Kearney classrooms, that they have to make a special effort to protect them from exposure.
Oh, and my students can tape my classes any time they want.
