In the late 1970s I started a PhD on a similar topic. I discovered that it was the way the material in the text-book that was structured that had the major impact on the political consciousness of the student. In other words, it was the way the material was studied that was more important than the actual topic. That the student had to be turned from a passive to active learner. I concluded that as textbooks were being produced by large corporations in order to deliver the “dominant ideology”, things would only change if educators produced their own teaching materials. However, students had been brought up using professional looking books, videos, etc. Therefore, to really work, radical teachers needed to establish their own publishing companies. I decided to do that and this meant that I had to bring an end to my PhD (I submitted what I had done and got a MPhil instead).
The Internet of course has made it far easier for teachers to produce material that questions the dominant ideology. It is so cheap to do this it is possible to offer them to students, wherever they are located, for free. Whereas multinational corporations have to charge for these materials (subscription sites). Therefore, there has been a power shift that has revolutionary implications for education.
Thanks for starting this discussion!
I can agree with your interpretation of textbooks and their commercial dependence. I´m not quite sure that material from the Internet will replace textbooks, not yet. In that case, wouldn´t that mean a risk for manipulation? Many teachers and pupils can, I´m sure, use the internet material for good purposes, but not everyone.
What do we mean by "radical teachers"? Those who "know" something others don´t know or those who oppose our democratic society? I hope not! In sweden there is a clear and present message from the Parliament and the Government: Teach and persuade the children about democracy, even in History! The question is: -Is the mission ackomplished? Schools teach democracy, but from our present point of view. Textbooks don´t recognize or present the historical differences or the changing perspectives. I think that schools can do better to help pupils analyze, interpret and understand democracy and history.
