Lenney (1977) concluded that achievement gender differences were predicted by females' lower self confidence and expectancies in competitive situations, identifying three variables that mediated female self confidence in achievement situations, (1) task appropriateness. (2) social comparison, and (3) feedback. The present study manipulated all three mediating variables with 240 undergraduate 18-25 year old female subjects with the pursuit rotor task that requires tracking a moving (40 rpm's) white light with a hand-held stylus for 60 seconds. Response measurement was based upon time on target. Subjects were tested over five trials while setting goals for each trial. Females were randomly assigned to a male appropriate, female appropriate, or gender neutral task condition, a competition or alone condition, and to one of four feedback conditions (no feedback, feedback about own performance only, feedback about own performance that provided the perception that subject was performing better than an opponent and/or average on each trial, or feedback about own performance that provided the perception that subject was performing poorer than an opponent and/or average on each of the five trials). Results from the 2 (social comparison) X 3 (task appropriateness) X 4 (feedback) ANOVA were contradictory to previous findings (Corbin, 1981; Petruzzello & Corbin, 1988) as females performed significantly better in competition than alone. Data support the conclusion that presentation of clear and unambiguous feedback enhanced female self-confidence (Corbin, 1981; Petruzzello & Corbin, 1988; Lenney, 1977). Data also provide null findings for the task appropriateness condition which contradicts the previous research (Corbin, 1981; Lenney, 1977) in that females perceiving the task as male appropriate did not exhibit less self-confidence and perform poorer than when the task was perceived as either female appropriate or gender neutral. Conclusions reflect methodological differences from previous research and changes in gender role identification that have significantly impacted on female self-confidence and performance in competitive situations.

<p>This dissertation explores the issue of under-representation of women in STEM fields in high school and the early years of college. One of the major contributors to the persisting gender earnings gap is male-domination in the STEM workforce. Women are under-represented in STEM occupations since they are less likely than men to take advanced STEM courses in high school and to choose STEM majors in college. While the gender STEM gap does not exist at early ages according to most studies, it has been shown that girls start to lag behind boys in Math tests after middle school.</p> <p><br></p> <p>In Chapter 1, I investigate the STEM gender gap in the context of teacher-student gender matching. Using a fixed-effects regression model, and Chilean administrative education data on SIMCE and PSU exams and college application, I explore whether high school girls perform better in Language and Math when they have female teachers, and whether a female Math teacher impacts girls’ preference towards STEM programs when enrolling in college. I find that female teachers improve girls’ overall performance in high school Math exams for all school types, and college entrance exam Math scores for public school girls. However, they negatively affect girls’ probability of choosing STEM majors when enrolling in college. They negatively affect boys’ high school and college entrance exam Language performance and private school boys’ college entrance exam Math performance, but positively affect boys’ college STEM preference. The presence of female Math teachers in high school has negative effects on both boys’ and girls’ college entrance exam Science scores. There is significant heterogeneity in these effects between public, voucher and private schools. The negative preference effect is significant only for</p> <p>high-performing girls.</p> <p><br></p> <p>Chapter 2 uses restricted NCES data (HSLS:2009 and ELS:2002) and difference-in-difference methodology to explore whether the $4.35 billion federal Race to the Top (RTT) program of 2009 had impacts on overall educational and enrollment outcomes, and gender gaps in these outcomes for high school students in the US. Besides the major objective of making students better prepared for college and future careers, a significant aspect of the RTT program was its emphasis on reducing barriers to women’s entry and success in STEM fields in higher education and the STEM workforce. I find that the program was not successful in fulfilling the major objectives of improving students’ educational outcomes, reducing achievement gaps or improving women’s representation and performance in STEM fields. It prompted students to take fewer and easier courses in high school and increased gender gaps in 12th grade GPA and SAT Math score. While there was a modest reduction in the gender gap in first year college GPA, there were neither any improvements in boys’ or girls’ college STEM credits and grades, nor</p> <p>any reduction in gender gaps in these outcomes.</p> <p><br></p> <p>In Chapter 3, I use the same restricted NCES data as in Chapter 2, data on state policy obtained from Howell and Magazinnik (2017) and difference-in-difference methodology to explore whether states’ adoption of “college and career ready” common K-12 standards affected the overall educational and enrollment outcomes of high school students in the US and gender gaps in these outcomes. I use the 2009 Race to the Top (RTT) program as a source of exogenous variation, since one of the major policies promoted by the program was the adoption of higher K-12 standards across the US. I find that the tougher standards led to students taking relatively more non-STEM oriented, and thus arguably “easier” courses and increased gender gaps in STEM coursetaking.</p> <p>Notably, they drove low performing girls out of college education, which resulted in a more competitive college-going female population. This in turn, led girls to outperform boys once enrolled in college, specially in STEM courses. Thus, common standards-adoption whose goal was to improve college and career readiness failed in this endeavor, but made the pool of college-going women more competitive and inadvertently levelled the playing field</p> <p>for college-bound women.</p>
