Supported Reading is a fancy term for "Follow along while so-and-so reads to you." It has been shown to help all types of students learn in all subject areas.
Since learning math is like learning another language and supported reading is another form of effective learning, wouldn't it be great to have a language lab for algebra? Math learners would get to Preview and Review content, and they would be "38% more likely to learn" when listening to someone read about algebra. Teachers would benefit from this, too. If their students preview the material, teachers get a classroom full of active listeners.
AlgebraCAST is a library of podcasts for every card we have designed. It's another way to learn algebra. When students follow along with AlgebraCARDS, every podcast has a purpose. This multimedia format is a Supported Reading technique that also gives learners control of the reader, a very important static image, and their own personal listening lab.
