I’m a history teacher, and I use BlackAdder because it is funny, which helps learning, and because it is part of an interesting historiography of the First World War that saw for really the first time the voice of the ordinary man emerge from war. It is funny, because it reflects a truthful element of how some people felt about the conflict. No historian would use only one source, and I find it unlikely that any teacher is using only 3 hours of footage to teach a course which is usually 2 terms long. Gove is after a headline, not a sustainable answer to the real problems in our education system.
