Interest in learning has an important role in learning context. Recent research on interest focuses not only to how much interest there is but also on the extent that the interest develops. The less-developed and well-developed interests are established in different ways and have different functions. However, a unidimensional model proposed in previous studies does not clearly capture the differences in the development of these interests. This article proposes a model that identifies the level of development of interest based on three elements: continuity, inherence, and value. These three elements define the development of interest more clearly and make it possible to describe different psychological states of interest. Using this model, previous studies were reviewed and analyzed in an integrated manner. Finally, we discuss future research on both interest and insight for educational practice.
