Another example is found in the work of music educator and researcher Kay Edwards, who also reached the conclusion that attention to authenticity increases student response to learning. In her qualitative study of the response of children to a unit on Native American music, she found that the group using instruments of the Navajo, Hopi, Apache, and Yaqui peoples generated more journal responses overall (her criterion measure) and more responses about instrument playing than the groups with the inauthentic (traditional music room) instruments.
