Diversity Pedagogy Theory (DPT) is a set of principles that point out the natural and inseparable connection between culture and cognition. In other words, to be effective as a teacher, he/she must understand and acknowledge the critical role culture plays in the teaching-learning process. DPT maintains that culturally inclusive teachers (a) observe children's cultural behavioral patterns to identify individual and group cultural competencies and skills; and (b) use this knowledge to guide their teaching decisions. In this article, the author introduces Diversity Pedagogy Theory, describes the structural aspects of DPT, and examines the relationship among culture, cognition, teaching, and learning. The author also provides classroom vignettes explicating the theory in practice and provides suggestions for classroom applications. In the conclusion, the author asks that teachers consider the importance of becoming conscious of their thinking habits and encourages them to begin and evolve into a culturally competent educator.
