3 Outline of Presentation Framing of the APSB. "What have we learned about engineering students and their transitions to the world of work? And what are the implications for educational practice?"C. What is next…
4 The Pipeline Metaphor11. Expresses the typical process students take in preparation to become engineers2. Expresses the activity of students who prematurely exit the preparation process3. Expresses the activities being done to repair the preparation process23We chose the pipeline metaphor because it was the most familiar to engineers and was adequate for capturing our intent, which was to examine and present engineering trends in preparation of women and minority students. Various aspects of the concept of the pipeline has been used to express salient aspects about the preparation process.
5 The Pipeline Metaphor11. Expresses the typical process students take in preparation to become engineers2. Expresses the activity of students who prematurely exit the preparation process3. Expresses the activities being done to repair the preparation process4. Expresses the successful exit as an engineer243We chose the pipeline metaphor because it was the most familiar to engineers and was adequate for capturing our intent, which was to examine and present engineering trends in preparation of women and minority students. Various aspects of the concept of the pipeline has been used to express salient aspects about the preparation process.
6 Subset of PipelineWe worked with the concept that the entire pipeline included students K-6 and ended with several successful exits, with Baccalaurate, Masters or Doctorate in Engineering

25 Engineering Design: Freshmen Take 1 Survey Question:You have been asked to design a playground. You have a limited amount of time and resources to gather information for your design. From the following list, please put a check mark next to the five kinds of information you would MOST LIKELY NEED as you work on your design…
26 Information Categories by Gender *p < 0.10 or **p < 0.05, Fisher exact
27 Engineering Design: Freshmen Take 2 Ten Minute Paper and Pencil Engineering Task:Over the summer the Midwest experienced massive flooding of the Mississippi River. What factors would you take into account in designing a retaining wall system for the Mississippi?
28 Examples of Detail and Context Design detail“cost of materials”“check the budget available for the operation”“how to contain the river water that has flooded out”Design context“aesthetic appeal – is it going to draw local complaint?”“the surrounding habitat – make sure little or no damage is done to the environment”“would wall impact use of the river by industry?”

We look at longitudinal analysis of how students conceive of design in engineering.
32 Conceptions of design: Important design activities Of the twenty-three design activities below, please put a check mark next to the SIX MOST IMPORTANT...
33 Important design activities, by year Comparison was on paired data, on only those students who responded in both years.Design activities are sorted by Year 4 frequency. Four of top five match top five from expert data (shown in backup slide): Understanding the problem, Communicating, Identifying constraints, Brainstorming. Experts also had Seeking information in their top five, while APS seniors had Making decisions.Note that Identifying constraints went up between Years 1 and 4. Let’s take a look how the design activities split between those that went down and up between Years 1 and 4.side note: Although students were less likely to choose Communicating as seniors than as freshmen, still about half of seniors included it among their 5 most important.statistical tests: McNemar for paired data for each item by year (Communicating p = 0.022, Planning p = 0.010, Visualizing p = 0.001, Identifying constraints p = 0.000, Iterating p = 0.006)data source: \\zhora\celt_stu\APS Engineering Thinking and Doing\Year 4, \surveys\analysis\JEE_Analysis_MIDA_InfoGather_Data_AM_v5_wInst_NEW.xlsYear 1 vs. 4Significant changes asterisked (**p 0.01, *p 0.05).

In contrast, the activities more frequently chosen by the students as seniors (right) are more precise and engineering-specific.Minnesota (Cohort 1’) data also shows shift toward more precise, engineering-specific vocabulary (vs. common English words like).We expect conceptions of design to be affected by institution-specific factors, especially curriculum. Indeed, first analyses of institutional variation in Year 4 responses show that Stanford seniors are significantly more likely to include Prototyping (p < 0.01) and Visualizing (p < 0.05) in their set of most important skills.statistical tests: McNemar for paired data for each item by year (Communicating p = 0.022, Planning p = 0.010, Visualizing p = 0.001, Identifying constraints p = 0.000, Iterating p = 0.006)data source: \\zhora\celt_stu\APS Engineering Thinking and Doing\Year 4, \surveys\analysis\JEE_Analysis_MIDA_InfoGather_Data_AM_v5_wInst_NEW.xlsSignificant Year 1–4 changes asterisked (**p 0.01, *p 0.05).
35 ETD Summary Complex gender differences First-year women more context-oriented, but not at the expense of focus on design details.Implications on continuing challenge to recruit, retain women.Meeting the ABET a–k and 2020 challengesSeniors value and have learned traditional “core” engineering, as well as some “people” skills (teamwork, communication)....but not issues of societal/global context, contemporary issues.The general understanding is that women differ from men in their interest in society, service, and people. ETD design task data shows gender differences in performance that correspond to this difference in interest or focus.

38 To What Extent Do You Consider Your School to be Diverse?
39 Does Your Gender Affect Your Views of Becoming an Engineer?
40 Female Student’s View Does your gender affect your views of becoming an engineer? “… there are societies, like Society for Women Engineers…that does help change our perspective on being an engineer…it’s ‘cause I’m female, because I’m a minority and I’m not used to being like that because I’m a white middle class individual… it’s hard to become an engineer, it’s real intimidating to be ahm, working for… predominantly all males…it’s kind of a challenge to me,…I can do this, I can pioneer this and be a female engineer, be just as good as a male engineer” Mountain TechThis student from CSM represent many womens views across all schools. Some of the women are more encouraged than others. Many feel as though they have a gender advantage because there are so many male s in the field that they are guaranteed a job upon graduations. Others feel that in the male dominated profession that they are going to be overlooked or treated with less respect because of their gender.Howard female students were less likely than all groups to say that their gender affects their views of becoming an engineer.Stanford women like the idea of feeling elite among the men. One woman mentioned that she really liked being one of three girls in her math class.A female student from UW offered another interesting perspective. She noted “…I am thinking well, as an engineer am I still going to be able to take time off to have a family…leave for eight years and raise my kids and still get back in? Is this a career that I can do part-time on, while raising my family…?”
41 Male Students’ View Does your gender affect your views of becoming an engineer? “…if the females... have an advantage, just because [of] things like affirmative action … where they give certain advantages to some minorities, I wonder if it is a disadvantage being the majority?” University of West State-MLike the females, male engineering students are aware of the dynamics in the field. The know that the field is heavily male dominated. However some men believe that that give them an advantage. Others believe that it keeps the competition tight. Some have even thought that females are directed from one type of engineering and steered into others (the more feminine fields).Another UW males stated, “Yes, I think that engineering I predominatintly male at this point and I feel like the competition among males is higher because everybody focuses so mucho diversity that if you are a female entrusted in an engineering degree, you have people who are willing to go out of their way to try and encourage you to be in engineering. I feel like it’s a little unfair at times ahm and I’m one of the people who feels like the best candidate for the job is the best candidate. Ahm but of course that’s biased, because our current system favors someone else as opposed to me naturally I’m gonna favor a system which favors myself.“It’s more natural for males to be engineers.” Coleman University-M
42 Diversity SummaryTo most engineering students, diversity means difference (school, gender, race , geographical, major field, politics, religion).Diversity can be an uncomfortable topic for students to discuss.Students recognize the impact of diversity on their careers.
43 What’s Next? Mountains of data to be analyzed . . . . stay tuned Possible Relationships to WASC:• Study of knowledge evolution• Curricular Flow-educational careers study (Dan McFarland)• Model for study in other fields
46 What have we learned: selected findings from the APS team Decision Making & “persistence”; (Sheppard)• Identity (Stevens)Design Skills and Perceptions (Atman)Institutional Factors (Fleming)
47 Identity٭: Becoming an Engineer Stevens, Lead; Amos, Garrison, Jocuns IdentificationThe practices by which an individual becomes identified with engineering (by her/himself and by others)NavigationHow individuals navigate a pathway to becoming an engineerAccountable Disciplinary KnowledgeActions when performed are counted by someone as engineering knowledgeOur ethnographic perspective has enable us to take an holistic approach to the study of identity development among engineering students. This approach we refer to as becoming an engineer and it enables us to approach this ethnographic problem by observing three dimensions that change over time. While these are presented as three separate dimensions, it should become apparent during this discussion they work together in forging a trajectory of becoming an engineering.
48 Identification (Changes over time) Increasing solidarity with other engineering studentsWe/they language, “Techies” and “Fuzzies”Identity displays – websites, clothing, social activitiesIncreasing expression of views that they are different from non-engineering studentsEngineering work is harderHarder work justifies future lifestyle
49 Navigation at UWestDifferent navigational pathways have a clear effect on identification of students as engineersStudents not admitted during their first year can be lost during this pre-engineering phase.Once admitted to engineering majors, students are granted literal “keys to the clubhouse” — a critical rite of passage that changes how students identify themselves as engineers.Students also took a more agentive stance to coursework and learning once admitted.I think Uwest is a special case but I think the issue of the tension between weed-out and include is a productive one to consider on all the campuses. The opposite end is Coleman, where they effectively choose Engineering. Engineering does not choose or exclude them.
50 Gender Identity/Navigation at UWest Women and men both form identities as engineers that seem quite similar across the genders and draw on stereotypical engineering image (problem solver, good at math, etc.)However, in competitive admission practices at UWest women students are believed to have an advantage over men; presence of organizations supporting women also seen by men as evidence that women need help.Men use this explanation of women having an advantage in admission to set up a rationale (that involves no fault of their own) for their potential failure to get into the major.It is suggested that some believe that women who get into the major may be less qualified than men who do not. This leads to women working to “prove themselves” or working to appear deserving of being in engineering. This seems cultivate some stereotype threat (Steele).Women go ‘underground’—seeking help from other women as a first resort, makes them sensitive to criticism of their male peersForming an identity as an engineer is important for both men and women. Identification for women engineering students is pretty similar to that of men students. Both men and women seem to pick and choose pieces of the “stereotypical engineer” identity to attribute to themselves. Like their male counterparts, women do not necessarily embrace all aspects of a “stereotypical” engineering identity. Some identify with (or find sponsorship in) the math-heaviness of the major, for others identification may be signaled by joining an engineering sorority or being awarded a special scholarship or office in a department club.At Uwest the competitive nature of the admission process creates interesting dynamics, including a competitive climate in the first two years, pitting students against one another who are seeking a limited number of spots in the department. Related to this competitive climate is the way in which groups, such as women are seen as having an advantage over others in the admission process. Several men AND women expressed the belief that lower standards were applied to women applicants than were applied to men applicants. This belief has several consequences for both men and women.
51 Accountable Disciplinary Knowledge (Changes over time) During first two years:Technical subject matter prerequisites (mathematics, physics, chemistry) outside of engineering. Little exposure to engineering coursework.Lecture-based teaching, individual-based problem sets and exams (except labs)During latter two years:Kinds of problems to be solved shifts to more open-ended problemsStudents’ relationship to data changes. They go from mathematical puzzle solvers to data users to data collectorsBiggest changes in accountable disciplinary knowledge come through in experiences of Capstone project courseIn becoming an engineer we noticed that what counts as accountable disciplinary knowledge for engineering students changes over time. During the first two years students have little exposure to engineering coursework or engineering problems because they are taking prerequisites in math and other sciences. Courses are presented in a sequential nature where one course was considered to be mastered prior to enrolling in the next course in the series. Our students noted that this was not a reality. For instance, Adam mentioned to us during his fourth year interview that he felt that the did not master a course until he had completed the course that followed it.Early courses are also lecture based where individual students are responsible for completing assignments usually in the form of problem sets. The exception was labs, but these were often performed as a pair or small group and they were still working with problem sets.During this phase many students at UWest mentioned that there was a considerable amount of competition where they were competing with classmates for spots in the department to which they will be applying.There is also the thing about Adam mentioning that he felt he understood a course after he had taken one that followed it.
52 Accountable Disciplinary Knowledge (Changes over time) Examples of two UWest students handling this change over time:Adam struggled as problem-set based mathematics (school math) was displaced by group work and open-ended problemsSimon came into his element with the AA capstone; he drew on his wind tunnel experience (he ran the wind tunnel at UWest) and was the expert in some of the tests (even in relation to the professors/instructors)The capstone was considering to be the rite of passage between the world of being an engineering student that of a practicing engineer. One of the reasons for this was the long hours put in where students had even less free-time than they normally did. One student mentioned to us that he has only seen his family for 30 minutes over the past 3 weeks and he lived at home. These courses provided the most clear glimpse at an actual engineering workplace than even internships and/or co-ops; where students did not always receive actual engineering practice. Students were presented with open-ended problems that could solve with a variety of means. They worked in groups or teams. The instructors (some of whom actually were in engineering firms) acted as consultants and in some cases clients. In a few of the courses students had real-worlds clients, e.g. the mechanical engineering capstone worked with dental professionals, the chemical engineering capstone was working with a hydrogen-based economy that were planning to submit the various results to the local transportation authority.
