Using the Technology Engineering Attitude Survey (TEAS) and the Draw an Engineer Test (DAET), this investigation compared the experiences of students enrolled in a mixed male/female 7th grade classroom with those enrolled in an all-female 7th grade classroom. We noted that the students in the all-female classroom had different interests and attitudes towards Technology and Engineering and their enrollment went up in the course and in subsequent classes. Some self-reported perceptions of STEM improved through participation in the project, but others remained stagnant or dropped.
