The concept of learning styles has tremendous logical and intuitive appeal, and educators' desire to focus on learning styles is understandable. Recently, a growing emphasis on differentiated instruction may have further increased teachers' tendency to look at learning styles as an instructionally relevant variable when individualizing instruction in increasingly heterogeneous classrooms. We discuss the overlapping concepts of individualized instruction and differentiated instruction, briefly review the evidence base for learning styles, and argue that instruction should indeed be individualized and differentiated. We conclude that there is insufficient evidence, however, to support learning styles as an instructionally useful concept when planning and delivering appropriately individualized and differentiated instruction.
