Spiral curriculum, a concept widely attributed to Jerome Bruner, refers to a curriculum design in which key concepts are presented repeatedly throughout the curriculum, but with deepening layers of complexity, or in different applications. Such treatment allows the earlier introduction of concepts traditionally reserved for later, more specialized courses in the curriculum, after students have mastered some fundamental principles that are often very theoretical and likely to discourage students who are eager to apply the concepts they are learning to real-world applications.
