Free online courses are always appearing on the internet, and Annenberg Learner offers an interesting variety of them. There's an assortment of traditional college courses which are presented in the form of online video documentaries. Two foreign language courses are on offer, French in Action and two levels of the Destinos Spanish course. There's also a variety of history courses. One blogger thinks that the course A Biography of America could replace traditional history textbooks. Annenberg Learner might also be considered as a way to homeschool the "tough" high school subjects, as there are courses in chemistry, physics, microbiology, and statistics. Documentary series often present the material in a more entertaining and easy-to-absorb fashion than traditional textbooks, so Annenberg Learner might be worth a look.
