This study investigated the family as a context for the gender typing of science achievement. Adolescents (N = 52) from 2 age levels (mean ages = 11 and 13 years) participated with their mothers and fathers on separate occasions; families were from predominantly middle-income European American backgrounds. Questionnaires measured the parents' and the child's attitudes. Each parent also engaged his or her child in 4 structured teaching activities (including science and nonscience tasks). There were no child gender or grade-level differences in children's science-related grades, self-efficacy, or interest. However, parents were more likely to believe that science was less interesting and more difficult for daughters than sons. In addition, parents' beliefs significantly predicted children's interest and self-efficacy in science. When parents' teaching language was examined, fathers tended to use more cognitively demanding speech with sons than with daughters during one of the science tasks.
