Exactly what I'm doing this year with my 8th Grade Physical Science students...

A Classroom Experiment: Ditching a Textbook - ProfHacker - The Chronicle of Higher Education: "I'll be replacing the traditional 'conflicting viewpoints' textbook, though, with materials gathered from a variety of resources: the web, the news media, the popular press, and more traditional scholarly venues. As the semester progresses, the students will take on some responsibility for determining course content."

I'm hoping guessing this will be a precipitous trend in the coming decade with a tipping point about 2-3 years out. My children will never know of dreaded back strain due to poorly conceived cookie cutter textbooks. Primary sources, love of reading and engaged critical thinkers will then thrive.
