Talking about Leaving Revisited: What do we know about why
6/4/15 Talking about Leaving Revisited: What do we know about why undergraduates leave the sciences? Elaine Seymour, University of Colorado at Boulder, Joseph J. Ferrare, University of Kentucky Gardner Ins/tute Symposium on Student Reten/on, Asheville, NC, June 8-‐9, 2015 Should We Still Be Talking About Leaving? A National Portrait of Switching Using the Beginning Postsecondary Students Survey 2004/2009 Cohort NOTE: All findings are preliminary and should not be cited. 1 6/4/15 National & Institutional Team Joseph J. Ferrare, University of Kentucky You Geon Lee, University of Wisconsin-Madison Tim Weston, University of Colorado Boulder Among first time beginning students who began their postsecondary education in a bachelor’s degree program… 2 6/4/15 Switching rates for those who initially declared a major falling outside of STEM and switched to another “non-STEM” major Preliminary Findings from Multivariate Analysis • The analysis of non-STEM majors suggests that the gender and racial switching patterns observed in STEM majors are unique even when controlling for a wide variety of covariates. • Women are 1.51 times more likely than men to switch from STEM majors even when controlling for academic ability, family background, undergraduate experiences, and type of institution. • The odds of switching for men and women in non-STEM majors are statistically identical. 3 6/4/15 Preliminary Findings from Multivariate Analysis • Whereas Black men were much less likely to switch into STEM than White men, Black women were more likely to switch into STEM majors than White women and even significantly more likely than Black men. • In contrast, Black women were significantly more likely to switch out of STEM than their male counterparts, which is consistent with the fact that, on average, women were more likely than men to switch out of STEM. • In short, Black women were more likely to switch into STEM majors, but they were also more likely to switch out. NOTE: Even though this finding was statistically significant, it was generated from a very small sample size and should be interpreted with caution. The Persistence Study Team members: University of Colorado at Boulder: Elaine Seymour, Anne-Barrie Hunter, Heather Thiry, Dana Holland, and Raquel Harper Coding and Hypotheses from the Switcher interviews. Note: No findings are, as yet, available. 4 6/4/15 The Interview Sample 311 students were interviewed at the six study sites. 98 (31.5%) switchers and 213 (68.5%) non-switchers. Both samples were subdivided by sex, race/ethnicity, discipline, and (for non-switchers) low “math readiness” scores on college entry (30% of all nonswitching seniors). Overall, women are 60.5% of the sample and men are 39.5%. Students of color are 40.2% of the sample and white students are 59.8%. The Codebook: deductive and inductive codes. . Code categories. Factors contributing to switching and persistence for both switchers and non-switchers: • Reasons for choice of majors and career aspira1ons: how well grounded in interest, understanding, relevant experience; who influences choices; influence of the economy and job markets. • High school prepara1on: in sciences and math, and in college-‐ level skills (study, independent learning, /me management). • Issues of transi1on to STEM majors and college level work. • Aspects of students’ learning experiences and their consequences (both in STEM and non-‐STEM majors). • Classroom climate. Compe//on/collabora/on, belonging, responses to weedout experiences. Gender and race/ethnicity: aXtudes, beliefs, experiences, explana/ons. 5 6/4/15 • Sources of academic and personal support; their significance for persistence: Faculty, TAs, advisors, peers, campus groups, family, etc. • Learning identities, behaviors, attitudes: taking responsibility for learning and problems; motivation, survival strategies. • How financing college: influences on persistence • Parental influences: choice, financing, responses to students’ concerns and switching decisions. • Switching processes: push, pull, conflicts, stages. • Consequences of switching; benefits & gains; costs & losses. Emergent Hypotheses HIGH SCHOOL PREPARATION & COLLEGE TRANSITION Under-preparation in high school— in math and the sciences, study habits or time management—creates switching risks. Deficiencies not identified and addressed quickly prompt early switching. Students of color, working class or first generation students from under-resourced high schools may be at enhanced risk. All students may be at risk where high schools award high grades for modest effort and students fail to develop study skills and work habits required in STEM majors. Overcoming high school deficiencies and adjusting quickly to college modes of work make the period of transition from high school to college critical for survival in STEM majors. 6 6/4/15 CHOICE • Unexamined or under-informed major or career aspirations put students at risk of switching. Conversely, a well-grounded, driving interest in the major and related careers supports persistence. • Some aspects of our data suggest a culturallysupported shift to parental approval of STEM majors and careers for daughters. Noted in: forced choices, discounting of non-STEM aspirations, strong preference for careers perceived--sometime erroneously--as high-paying; unsupportive parental attitudes towards difficulties in STEM majors, and negative responses to switching decisions. GRADES AND IDENTITY Difficulty in overcoming an internalized perfectionism that ties identity to high scores poses persistence risks. Noted in TAL-1, this may now be a stronger trend where high school grades, achieved with moderate effort by talented students, promote high expectations by parents and a sense of entitlement in students. Some interviewees describe letting go of high grade expectations; others find it difficult to disentangle their identity from their grades. Presumptions that their grades are ‘poor’ also pose survival risks in majors where traditions of low grades and curve grading make it harder for students to know how they are progressing. These effects may be stronger among women. 7 6/4/15 UNINTENDED CONSEQUENCES OF WEEDOUT CLASSES Weed-out class practices may prompt losses of particular student groups from STEM majors. Departments and faculty who organize and teach weed-out classes have no way of knowing what students they are weeding out and why. o Gatekeeper classes (often in chemistry, physics, and calculus) may disproportionately weed out students who are non-white, working class, first generation, especially those from under-resourced high schools. Inadequate high school preparation may be too great to overcome where weed-out classes are encountered early. The role of advisors in steering under-prepared students around such courses until their skills have been built up may be critical to their survival. o Through their negative impact on GPAs, weedout classes may redirect students’ aspirations away from careers that entail competitive professional school entry (e.g., medical, vetinerary, dental, law) to careers seen as less desirable, but more attainable with a reduced GPA. Such shifts may be notable in majors serviced by weed out classes, such as the life sciences or engineering. As in TAL-1, we have identified high achieving switchers: this may be one such group. 8 6/4/15 Pedagogical Practice in Scientific Purgatory: An Analysis of Gateway Courses NOTE: All findings are preliminary and should not be cited.

Chalk Talks (n=34 / 48%): – – Courses that are facilitated by instructors who spend the vast majority of instructional time lecturing at the chalkboard and frequently posing questions to the class. Students experience very little peer interaction, demonstration of knowledge, or the use of technology. 2. Slide Shows (n=21 / 30%) – – – Courses that are facilitated by instructors who spend the vast majority of time lecturing through the use of pre-made PowerPoint slides. A significant amount of class time is also spent lecturing at the chalkboard or lecturing without any visuals or demonstrations. Students in slide show courses spend more than twice as much time interacting with their peers as do those in chalk talks, and are more frequently engaged with real-time assessments (e.g., clickers). 3. Inter-activities (n=9 / 13%) – – Students spend the vast majority of their time interacting with their peers in small groups while the instructor moves throughout the room discussing the material and answering questions. In nearly half of the observed 2-minute intervals students are engaged in some form of problem-solving activity, and also spend a significant amount of time creating and brainstorming new ideas. 4. Connectors (n=6 / 9%) – – – – Constituted by a high degree of variability in practice—most of which centers on illustrating, demonstrating, and connecting knowledge. In the process, instructors in these courses frequently utilize humor while posing display questions and student comprehension questions. Students experience frequent demonstration and illustration of course content and a variety of cognitive engagements, such as problem solving, creating, and connecting. Connector courses also make the greatest use of technology, especially digital tablets, demonstration equipment, clickers, and overhead projectors. 17 6/4/15 How do students conceptualize their experiences of gateway instructional practices and curriculum, and with what consequences? This multi-faceted analysis will draw on sources from three sources: Gateway study student focus groups, Persistence study switcher and non-switcher interviews and focus groups, and results from the SALG survey administered to students in the sample of gateway courses, 18
