Furthermore, genetic determinism and cultural deficit models cause and maintain the low educational attainment of minority students. What key evidence does author G. Solorzano use to support his thesis? I think the "key" evidence is G. Allport's (1979) list of racial stereotypes. In the list, it shows what people think or stereotype about Blacks, Chicanas, and Native Americans. By interpreting the list, we can understand why teachers have certain attitudes and behaviors toward students of color. For example, Chicanas are called "stupid" and "lazy," so teachers have low expectations and less motivation to teach them. As a result, different students are treated differently at school. Consider how each author's arguments reinforce/support each other and/or disagree with each other
