The study described is part of a larger project, Career Oriented Modules to Explore Topics in Science (COMETS), designed to integrate career education into the science curriculum. This study aimed to determine the attitudes of male and female students aged 10-16 toward scientists, science, women in science, careers in technical fields, and careers in science. The sample consisted of 1,235 adolescents located in three different-sized midwestern communities. Students completed instruments developed by the COMETS staff that included the Career Attitude Scale, a 130-item scale to measure attitude toward women in science, and a 49-item instrument to measure preferences for careers in technology and science. Analysis of variance was used to test for differences on dependent variables due to age and sex. Findings indicate that early adolescent boys are more positively disposed toward science and careers in technological fields than are girls in the same age group. Girls are more positively disposed toward women in science than are boys. The age of 13 appears to be a pivotal one for both sexes. Boys' scores all increase during this year and girls' scores decrease. This finding supports the arguments for early career education interventions. (Author/MLF)
