- Men are more likely than women to follow the complete persistence pathway to attain STEM degrees, but women are as persistent as men once they expect a major in STEM as high school seniors.
- However, men are close to three times as likely as women to expect a college major in STEM during high school.
- High school achievement, attitudes, and course taking are related to the subfields attainment, as well as the pathways of the STEM degree attainment.
- Among women who received a bachelor’s degree in STEM, most switched into the fields during college, after indicating interest or claiming majors in non-STEM fields.
- The fact that women pick up their interest in STEM fields during college might allude to the relatively more encouraging and supportive environment that college provides for women to pursue non-traditional fields, STEM included.
- Taken together, the results are more aligned with revolving door theory and support the contextual variability in the salience of gender to understand gender differences in attaining STEM fields.
2011 - Gender Differences in the Paths Leading to a STEM Baccalaureate
The author is testing several different theories in this study: The pipeline model and it’s associated cumulative disadvantage theory and then also the revolving door theory.
– The pipeline model suggests that women exit the STEM pipeline at every stage at higher rates in comparison to men.
– Cumulative disadvantage theory posits that early gender socialization leads women to be ambivalent toward math and science, manifested in a low expectation for STEM careers, which makes them further disadvantaged in choosing a college major in STEM and even less likely to obtain related degrees.
– Revolving door theory highlights the varying effect of gender socialization across different stages of the life course and contexts of development.
National Education Longitudinal Study (NELS: 88-2000) and its postsecondary transcript data. NELS is a nationally representative longitudinal study that spans from students’ eighth grade to eight years after high school, when students are about 26 to 27 years old. The sample size includes 9,370 students. Of all bachelor degree earners, the sample size is 4,036.
DVs:
1) A dummy variable indicating whether the bachelor’s degrees are in STEM fields, including life science, math, physical science, computer science, and engineering (of allsorts).
2) The three-category STEM subfield, consisting of life science, physical science, and engineering. Among 1,017 students who attained a STEM bachelor’s degree, 516 students were in life science, 286 students were in engineering, and 215 students were in physical science.
3) The three-category variable indicating the pathways students travel to obtain their STEM degrees. Among the 1,017 students who attained the STEM degrees, 424 students followed the complete persistence pathway, 258 students traveled the early switching pathway, and 335 students traveled the late switching pathway.
IVs:
– The key independent variables in this study include precollege achievement, attitudes, and course-taking variables. High school achievement variables include three standardized tests NELS administered to all the respondents at 12th grade in 1992: reading, math, and science. Attitude variables include self-assessment of one’s abilities, which indicates whether respondents think math or English is one of their best subjects. In addition, attitude also includes two variables that reflect one’s beliefs. One variable indicates whether having lots of money is very important, which was measured during the students’ 12th-grade year; the other variable indicates whether helping others in the community is very important. Attitude variables are all dichotomous. Course-taking variables include both math and science course-taking information.
– Race: The four categories of race/ethnicity include non-Hispanic Whites, non-Hispanic Blacks, Hispanics, and Asians.
– Family SES: This was measured by parents’ education, occupation, and family income.
– College selectivity
– First-year college GPA
