. Page 25.718.1 c American Society for Engineering Education, 2012 Impact of Self-Efficacy on Interest and Choice in Engineering Study and Careers for Undergraduate Women Engineering StudentsAbstractSelf-efficacy refers to the belief in a persons’ ability to perform a specific task. Starting inmiddle school, girls tend to underestimate their abilities in STEM. This confidence gap amonggirls persists through high school into college [1]. This gap is presumed to be partiallyresponsible for the gender gap in engineering and other STEM fields (e.g. computer science,physics). In 2006, women only earned 19.5% of the undergraduate BS engineering degrees in theU.S. Using the Life Course Expectancy Framework, this

appreciationfor the experience and skills gained from the leadership module, as well as an increase inconfidence for women as engineers.IntroductionProfessional skills are often underemphasized in engineering programs. These “soft” skills –proficiencies such as leadership, teamwork, and communication – are important attributes of asuccessful engineer. Traditional engineering curricula and lecture formats need to be revised toenhance these professional skills, as “the quality of future engineers depends very much on thequality of engineering education”1. Service learning and design projects are new pedagogicalmethods found to be effective in nurturing these skills2,3. Moreover, service learning has thepotential to attract and retain women in engineering4

The authors suggested that interventions to increase the number and effectiveness ofresearchers in an academic environment be focused on 1) reducing role conflicts imposed bymultiple environments, 2) providing continuity of training efforts, 3) creating a positive andrewarding mentoring culture, 4) and incorporating and evaluating efforts to increase one’sresearch self-efficacy beliefs.Not only must one be interested in a career pathway and provided with the optimal conditions topursue a career pathway, they must be supported in their work environments to achieve

, 2012 On the Fence: The Influence of Protégé-Mentor Relationships on Women Doctoral Students' Academic Career Aspirations in EngineeringStatement of Purpose According to a 2004 report from the Commission on Professionals in Science andTechnology, women in engineering and the physical, mathematical, and environmental sciencesmake up less than 6 percent of full professor positions.1 Two decades ago, researchers projectedthat occupational equity for females in science and engineering was just “a matter of time”—time for increasing the number of female Ph.D. students and moving them through the ranks ofacademia.2 However, the prediction that growing numbers of female Ph.D. students would leadto greater gender equity among the

These differences point to the need to re-examine the explanatorypower of some findings on STEM career success and advancement outcomes of female faculty inthe four-year sector in the context of two-year institutions.In this paper, we present a study to investigate (1) the extent to which the factors associated withadvancement and employment outcomes in the four-year sector translate to the two-yearinstitutional context, and (2) the extent to which there exist other factors affecting female facultymembers’ employment outcomes that are unique to two-year

15.367.2enrollment in engineering is almost saturated. Therefore, to increase engineering schoolenrollment and the nation’s supply of engineers, America must recruit and retain females asengineers15.Unfortunately, NSF data for 1995-2005 are not encouraging. These data show vast differencesin the numbers of male and female engineering students in undergraduate programs across thenation32. Female enrollment in engineering schools increased from 18.5% in 1995 to 19.8% in1999; however, by 2005, female enrollment in engineering schools had declined to 17.5%, a fullpercentage point lower than 1999 (See Table 1).Table 1.

engineering and higher education have been looking at this issue and trying to find waysto increase the number of women completing engineering degrees at the bachelors, masters anddoctoral levels.Even with the many efforts going on across the nation, the number of women pursuingengineering degrees is not increasing; and in some areas of engineering, the numbers are actuallydeclining. For many years at Michigan State University (MSU), we saw a steady climb in thenumber of women engineering students, especially in disciplines like Chemical and Mechanical.Through the 1990s, we averaged 22% women engineering students, well above the 16% nationalaverage. However, in 2000 we saw the numbers begin to drop, as they did nationally.Figure 1 compares first-year

The project included anoutreach teaching activity for 5th grade students at a local children’s science museum, a writtenreport, and an oral presentation. The supporting skills lab taught technical writing and editing,oral presentation skills, and interpersonal skills linked to Felder’s learning styles.1 Student teamswere assigned so that all majors, learning styles, and genders were represented in each team. Theactivities were assessed using four surveys throughout the semester.Women undergraduates in the course ranked learning styles, teamwork, writing and

While research outcomes are not entirelyconsistent on this point, evidence is that the gender and racial gap in persistence onceenrolled in an engineering major has narrowed to near parity. In a recent analysis, forexample, Lord et al.1 determined that contrary to prevailing perceptions, women and menpersist in engineering majors at approximately the same rate across all ethnic groups.Less encouraging is evidence that a gender gap persists after completion of anundergraduate major in engineering, when women were significantly less likely than mento express interest in pursuing jobs in engineering2,3,4.Conceptual FrameworkThe literature

, thepercentage of female PhD holders in full-time STEM academic positions at 2-year and 4-yearcolleges and universities has increased from 10.6% in 1985 to 25.1% in 2006 1. This increase hasbeen attributed to the increase in the number of females earning science and engineering PhDs.However, progress in faculty representation at research intensive institutions has been painfullyslow. A study of the top 100 science and engineering departments (as ranked by NSF) shows thatfemale science and engineering faculty had increased only 3% in the past five years up to a totalSTEM representation of 17% 2.In 2001, the National Science Foundation announced the ADVANCE program to address thedisparity in faculty representation.

Organizations are, in fact, gendered to the extent that they pattern “advantage anddisadvantage, exploitation and control, action and emotion, meaning and identity,” in terms ofdistinctions between “male and female, masculine and feminine.”6 Acknowledgement of suchgender-based organizational patterns is essential to

Forexample, in a fall 1998 study incoming first-year male engineering students had a more positiveperception of how engineers contribute to society than female students at five institutions (withadditional 10 institutions that were higher, but not statistically significant).1 The perception ofengineers as contributing to the welfare of society was also more positive among first year maleengineering students’ in 2006, where male students averaged 4.66 compared to females at 4.29(on a 6-point Likert scale where 4 = agree a little bit, 5 = agree, 6 = strongly agree).2Differences in the

Some of the prospective students apply,becoming applicants. The applicants are reviewed by the admissions department and a portion isadmitted. From those admits, a subset of students decides to attend the university, confirmingtheir intent to enroll and becoming enrollees. The final stage of the funnel is referred to as the“yield” and

The percentageof women in engineering is generally found to be lower than that of men (1 – 10). Studies have alsoshown that even if women join engineering programs, they may not continue (1, 5, 8, 9). As aconsequence, such disparities in engineering education can lead to inequalities in professionswith related social effects (1, 3, 4, 6, 9, 10).

IntroductionCurrently there is a significant gender gap in engineering and science.
