The Effects of Special Curricular Study of Mexican Culture on Anglo and Mexican-American Students' Perceptions of Mexican-Americans.
Anglo and Mexican-American students in six sixth-grade classrooms were randomly assigned to control or experimental conditions (four weeks of special curricular study of Mexican culture). The effect of the treatment on perceptions of MexicanAmericans was studied by having students respond anonymously to an attitude inventory. The posttest means were significantly lower than the pretest means for all groups, apparently as a consequence of greater honesty in responding. There were significant differences in the ethnic group means, but no sex difference. The length and intensity of the treatment were not sufficient to cause changes in the ethnic attitudes and stereotypes.
