With the best of intentions, colorblindness inadvertently renders students of color invisible.As I read that, the author is equating "colorblind" to "white". How did he make that leap? How does judging people not by the color of their skin but on the content of their character (or their schoolwork) equate to "white"?
Colorblindness can imply that there is something wrong with not being White, or that there is something embarrassing or insulting about acknowledging one’s race or ethnicity. Colorblind perspectives also may reproduce racial and cultural hegemony in school practices, such as curriculum choices, teacher expectations, testing procedures, instructional practices, and even more pedestrian tasks such as seating arrangements. Because of the growing racial diversity in the United States, it is vital for teachers to understand and have the capacity to acknowledge racial diversity, and create safe, affirming, and supportive learning environments for their students to develop the knowledge, attitudes, and skills necessary to dialogue about race-related issues.
Emphasize that teaching is not a neutral act. It is highly political, and issues such as race and class are always tied to teaching.
The author has some deep-seeded racial issues and is probably a racist.
BTW, this "helpful" racial advice was published by the NEA.
