As the nation's K-12 classrooms become increasingly more racially, culturally, and linguistically diverse, it is incumbent upon the science community to seize opportunities to attend to the rhetoric of reform, namely to enhance scientific literacy for all students. Using Critical Race Theory (CRT) as a framework, this study examined 112 nature of science (NOS) research peer-reviewed studies conducted in the U. S. from (1967 to 2013). Results suggests that while White participants are being represented in the NOS research, Black, Latino, Native American and other people of color, were found to be disproportionally excluded as participants. Implications of excluding these individuals are explored and suggestions for making NOS research more equitable are discussed.
