Marching to Different Drummers, 2nd Edition. This comprehensive book on learning styles was originally written in 1985, then revised by the authors in 1998. It is a great resource for understanding the history and research behind differentiated learning and learning styles, as indicated by the authors in this excerpt, “In this new edition of Marching to Different Drummers, we intend to help educators focus on learning styles theories by presenting the term with a small “l” and a small “s”: learning styles instead of Learning Styles. It is important to focus on the practical accommodation of individual differences through a variety of learning style models. By the same token, we very much value the extensive research that has given credence and depth to this area.” Portions of the book are available for free at this site. To read the whole thing, you may borrow the book from the library or purchase it on the site or on Amazon for $5.99.
