1. Introduction
The United States has been largely ineffective in sufficiently engaging diverse populations, including women and people categorized as ethnic or racial minorities, in science, technology, engineering, and mathematics (STEM) fields and career paths [
1,
2,
3,
4]. This shortcoming has resulted in a shortage in internationally competitive STEM talent and an insufficiently trained domestic workforce incapable of continuing past successes [
5]. To combat this, there has been a heavily focused domestic initiative to engage diverse populations and previously untapped underserved minority groups—particularly female participation in STEM. To begin framing this large issue, two general explanations are put forth for women’s underrepresentation in science: (1) Either women act differently from men (the difference model), or (2) they are treated differently in the culture of science (the structural deficit model) [
6]. According to the difference model, the causes of gender disparities in career achievement are held to lie within women themselves. The gender differences are said to be innate or else to be the result of gender-role socialization or cultural patterns [
7]. With regards to the structural deficit model (not deficits associated with women themselves), women as a group receive fewer chances and opportunities in their careers, and for this reason they collectively have worse career outcomes. In this model, the emphasis is on structural obstacles—legal, political, and social—that exist (or existed earlier) within the social system of science [
8].
To engage previously untapped human capital, there has been a corresponding shift in pedagogical diversity, curriculum diversity, faculty/staff diversity, and an influx of monetary resources in spaces of learning [
9,
10,
11,
12,
13,
14,
15,
16,
17]. Pedagogical strategies including active learning, project-based learning, and team-based learning all generally aim to increase engagement in students to support the development of their persistence in STEM subjects. More and more institutions of learning are recognizing the importance of fielding a diverse faculty offering to best serve their continually diversifying student population [
18,
19,
20].
Secondary to such innovations in education is understanding the parallel impact of said innovations on the persistence, perceptions, and STEM identity formation of the targeted diverse populations. This is not to imply that pedagogy or education structural factors are the only impactors of persistence in STEM fields because this issue is very nuanced and there are many impactors [
6]. Several social and systemic structures contribute to the complex identity formation of future STEM professionals. The formation of STEM communities, presence of relatable STEM mentors, self-efficacy, development of teamwork and leadership skills, and having meaningful research experiences all contribute to the persistence and identity formation of future STEM professionals [
21,
22,
23,
24].
In many instances, even with substantial innovations in the STEM educational offerings, said offerings continue to restrict the open participation of all students. Unfortunately, STEM in its purest form still carries a stigma regarding who may participate and how one must be pre-molded to fit into a historical culture of STEM. One such example of historical culture in STEM is gender representation across STEM disciplines, where the women who choose to pursue pathways in STEM disproportionately choose life science-based majors over physical science, math, and computer science majors (
Figure 1) [
25]. Data from
Figure 1 is also particularly interesting because it represents STEM PhD holders in academia and in terms of a rite of passage, academia is unequivocally the primary space where rite of passage is granted and communal perceptions are developed for the next generation of STEM leaders. In essence, issues of access, inclusion, equity, recruitment, and retention in academic institutions provide a direct lens into what should be expected in the future workforce, albeit in industry or academia. As recently as 2010, women only represented 20 percent of the full-time faculty population in Engineering, Math, and Physical Science fields; whereas in the life sciences they represented roughly 42 percent of the population. The three examples chosen in
Figure 1 paint very unique pictures of gender representation across STEM disciplines: (A) classic STEM fields in math and physical sciences that have historically been dominated by males, (B) the life sciences that have been uncharacteristically welcoming to women in STEM, and (C) the growth of an emerging STEM discipline where gender representation was essentially zero for both groups at its inception. This data begets the question, why did the engineering, math, physical sciences, and computer sciences areas not experience comparable female participation to that of the life sciences?
To approach explanations to this question, some have investigated differences in male-female natural aptitude for science [
26,
27,
28], personal preference [
29,
30], self-perception [
31,
32], structure and environment of academic science [
33,
34,
35], and gender segregation differences among academic scientists [
25]. To that point, it has been found that men and women have very few differences in their natural aptitude for science. Another significant component in the pursuit of a particular STEM discipline is the presence or absence of same-sex role models. It has been found that if classes in a major are taught by women, then women are more likely to pursue that major regardless of discipline [
36,
37]; however, differences may exist in a graduate school context. Nonetheless, in such an environment where, statistically speaking, the presence of “like” role-models may be more difficult to come by, significant hurdles may exist subsequently discouraging women and minorities from entering into these STEM spaces or forcing them out once they do enter. It must also be said that in male-dominated environments, it has been shown that women are more likely to switch out of STEM majors in response to poor performance compared to men [
38].
A particularly interesting assertion as to why women tend to migrate towards the life sciences involves the idea that innate differences exist between men and women which cause women to be better suited for and/or more interested in biology than the physical sciences. In a study comparing narratives of gender separation in science between mixed-gender communities of biologists and physicists in academia, women often used language that demonstrated a broader understanding of or emotional or societal attachment to the subject (meaning that women are better able to connect to the subject matter of biology, such as working with animals, versus the subject matter of physics, such as working with particles); whereas men often cited the abstract nature of physical sciences and specific mathematics abilities as drivers of their own interest [
25]. Finally, in another study respondents stressed differences in discipline specific outcomes, perceiving that biologists are more likely to work on research that would have practical consequences. More specifically, a postdoctoral fellow in biology talked about the social benefits that her research might bring: “I think women … want to have more of a sense that what they are doing is helping somebody. … Maybe there are more women in … biology [because] you can be like ‘Oh, I am going to go cure cancer.’” This respondent was intensely aware of the possible implications that her work might have on society, and this narrative was not common among the men studied in biology. This suggests that the perceived practical applications of biology are gendered, which may be a result of societal expectations that women are best suited to emotional labor, labor that involved one-on-one contact, helping another, particularly the production of an emotional state in another individual [
25,
39]. This assertion aligns favorably to the relatively recent integration of the arts into STEM practice.
A secondary strategy that has been implemented with success has been the incorporation of the “Arts” into STEM (STEAM). The merger of humanities and traditional STEM curricula enforces the idea that the 21
st century scientist and engineer must maintain a higher sense of responsibility for the societal outcomes that result from the introduction of new science and technology [
40,
41,
42]. Such incorporation of the humanities may dually serve as a net for attracting demographics that have not traditionally identified with the pure STEM fields and, secondly, as a platform for the training of socially aware and accountable STEM professionals who subsequently have a responsibility to train the next generation of STEM talent. The intended long-term impact of this work is to enrich science education by encouraging incorporation of a more inclusive and holistic view of science. Educational programs intended to pique interest in STEM disciplines can be further enhanced while also providing a framework for discussion of current issues, such as healthcare, health disparities, and sustainability to be addressed in the tradition STEM context.
If indeed differences exist between men and women’s interest in STEM as a function of their social-emotional connection to the subject matter, then reframing the traditional STEM narrative, traditionally devoid of humanities, into a narrative where STEM, the arts, and the humanities coexist harmoniously should be expected to come with more social-emotional connections conducive to gender-based persistence in STEM.
In this report, the aim is to show how the incorporation of ethics and social awareness into a standard summer engineering curriculum impacts the engineering identity formation of pre-college girls. This work will help to identify how and whether the intentional incorporation of ethics and social awareness into an engineering curriculum changes the engineering language and perceptions of engineering that pre-college girls have. Ideally, topics regarding the epistemological development of students would also be breached here; however, experimental limitations and timing have prevented that.
2. Theoretical Framework
To validate the relevance of ethics and awareness of social impacts resulting from produced science and technology, we draw on both The Framework for Quality K–12 Engineering Education (QEE) and the Socioscientific Issues (SSI) frameworks. The QEE framework was developed using a design-based research methodology, which is often domain dependent, and whereby it becomes crucial to outline any accompanying assumptions through its use [
43,
44,
45,
46]. Here the assumptions were gathered and addressed via multiple iterative cycles of revision to develop a refined and concise engineering education framework [
47]. This particular framework is essential in that it addresses a gap between dedicated standards and pedagogical procedures for incorporation of engineering education in the K–12 and undergraduate education contexts. Many of the pedagogical standards and procedures for engineering education at the undergraduate level are managed via respective engineering accreditation boards (i.e., Accreditation Board for Engineering and Technology (ABET), et al.); however, those same boards seldom exist for K–12 engineering education. Therefore, an important step towards the effective development of K–12 engineering education best practices and instruments rest on the consequent development of a standard K–12 engineering education framework.
Underneath the umbrella of The Framework for Quality K–12 Engineering Education lies 12 key indicators that, when taken together, summarize a quality engineering education for all students throughout their K–12 education experience [
43] and encompass both aspects that are fundamental to effective engineering and aspects that are more cross-cutting in nature as it relates to the broadly defined disciplines of Science, Technology, Engineering, and Mathematics. Here it can be found that Issues, Solutions, and Impacts (ISI), Ethics, Teamwork, and Engineering Communication are introduced as core competencies for a quality engineering education. These particular key indicators speak to the idealized holistic goal of STEM education [
42,
48]; however, in this context, they fall short on emphasizing the barriers that prevent STEM education from undoing its bifurcated ideology.
At this point it is most appropriate to introduce the SSI framework whereby many of the aforementioned shortcoming of the QEE are addressed and further developed. The practice of science can be viewed as possessing both normative (e.g., data gathering, observation, predictions, scientific methods and processes) and non-normative (e.g., prescribing courses of action, choosing to create selected products, decisions about what ought to be done) components [
49]. The obvious shortcoming in the QEE framework is its lack of acknowledgement of the social responsibility of an engineer to “prescribe courses of action,” “selectively create products,” and “making decisions about what ought to be done.” The QEE framework acknowledges that engineers should be trained to be aware of the social impacts of their work, but are not necessarily held accountable for their actions in a social sphere.
In combination, these two frameworks demonstrate that there is an important space for ethics and social action along with social awareness in engineering education curricula. Secondly, they demonstrate that the viability of society hinges on the voluntary and altruistic expression of holistically trained engineers. Our findings rely on the acceptance of these two constructs in that it will be shown that such holistically trained engineers must be trained in accordance to the desired ethical outcomes and it may not be assumed that they will act with sensible ethics in a vacuum.
3. Methods
3.1. Research Design
This is a grounded theory study utilizing the constant comparative method that begins with the initial question: How might the introduction of social science in traditional STEM curriculum alter the dynamics of STEM identity formation and narratives used to describe STEM subjects in young women [
50,
51,
52]? Here, observations are made and analyzed thematically, and camp participant survey responses are analyzed for insights into their perceptions and priorities in STEM social systems. Guidelines provided by Creswell were also consulted in developing the research design for this project [
53]. The approach is a convergent parallel-mixed methods and the research questions that are being addressed are: (1) Can a short intervention of social science in engineering change campers STEM language and perceptions of engineering within a 1-week long camp? (2) What themes emerge during design discussions between two camps? (3) What social themes emerge that can be linked to camper interest, identity, and environmental priorities?
3.2. Camps
Girls’ Adventures in Mathematics, Engineering, and Science (GAMES) Bioengineering Camp is an annual week long camp, designed to provide high school girls (rising 9th–12th graders) an opportunity to explore engineering and scientific fields through demonstrations, classroom presentations, hands-on activities, and contact with women in these technical fields. These camps are also staffed by all-female college student counselors who guide participants through their weekly activities and who are residence with them throughout the night in a dormitory setting. These counselors have STEM backgrounds and usually have the most contact hours with campers collectively.
There are many tracks of the GAMES Camp series and this study focused on comparing two camps with similar structures and differing themes, where the Aerospace GAMES Camp is most analogous to traditional physical science curricula and the Bioengineering GAMES Camp aligns most favorably to traditional life science curricula.
Aerospace GAMES Camp. The camp structure is project driven with students rotating through different stations and activities throughout the day. Lectures are used to introduce each area before the activity as well as guest lectures from speakers who work on research related to aerospace engineering. There are several projects throughout the camp that require the campers to use design skills but without a culminating project at the end of the week. Example activities include building a glider, rocket launches, using flight control simulator and a field trip to a flight school.
Bioengineering GAMES Camp. The camp structure is project driven, with students rotating through different stations and activities throughout the day. Lectures are used to introduce each area before the activity. The camp also has daily active-learning lectures and short activities led by social scientists that engage the girls in discussions of a social and psychological nature and set the framework for the day. Throughout the day, the campers perform scientific experiments and design projects related to the topic of the day. The camp also features a more in-depth culminating project to link together the themes and projects done during the week. Example activities include 3D printing, building electronic sight sensors, biomimetics exploration, and a field trip to a medical simulation center.
3.3. Participant Demographics
Participants included 52 adolescent girls between the ages of 12 and 18. Informed consent was obtained from both the caregivers of and the individual participants included in the study. All participants completed a demographic survey which included selecting one or more from the racial categories used by the U.S. Census Bureau: Asian, Black, White, or Other, as well as selecting Hispanic or non-Hispanic. Bioengineering GAMES camp has 26 consented participants with self-identified racial demographics of n = 3 White, n = 5 Asian, n = 5 Hispanic, n = 4 Black, n = 9 Other. Aerospace GAMES had 24 consented participants with self-identified racial demographics of n = 12 White, n = 9 Asian, n = 2 Hispanic, n = 0 Black, n = 1 Other.
3.4. Research Methods & Data Collection
3.4.1. Video Capture
Qualitative analysis of the respective camps was conducted to better understand the themes that were expressed through the language used by camp participants. The standard and socio-ethics enhanced camps were video recorded at two points near their respective conclusion: a project planning session and the final project presentation. The video time points were consistent with the schedule for both camps and represents a period where the students would have been subjected to the entirety of the respective camp curriculum. Both camps instructed students to complete specific conceptual engineering challenges. Each challenge involved the use of the engineering design process and expected for students to conceptually design, model, and to make design considerations. Discussion topics during planning and presentation sessions about the designs or design considerations were completely up to the students.
3.4.2. Student Video Thematic Analysis
The discussions captured were transcribed manually by the research team. Transcriptions were checked by a second individual to ensure accurate transcription and to address difficult segments of the recording. The videos captured during the camp were then coded using emergent themes that reflected the discussion (for example, themes involving engineering language used, ethical considerations made, and general perceptions of engineering were investigated). Codes were then organized into broader themes. Themes were separated by the type of curriculum exposed to the student groups (e.g., Standard and Socio-ethics enhanced).
The research team then used the data analysis approach described by reference [
54]. First, the team read all of the transcripts to familiarize themselves with the data as a whole. An open coding process was followed where codes were developed from the transcripts, followed by axial coding where the codes were analyzed to see if there was any connection between the codes. The codebook was developed based on the project research questions and the collected data. Codes were then organized into broader themes. As data was interpreted, meaning-making was initially organized by research questions—e.g., themes related to social engineering context.
A codebook consisting of two main code categories (design and social) was developed during first-cycle coding from survey and open-ended response. From the main codes, four sub-codes emerged from the Standard Summer Camp and six sub-codes emerged from the Socio-ethics enhanced Summer Camp. The analysis of data (video participant quotes) that was inserted under these themes is described later in this paper. All codes directly related to the research questions.
3.4.3. Pre- and Post-Survey
All camp participants were administered a pre-camp and post-camp survey, through the university’s college of engineering, that included questions pertaining to their perceptions of and interest in engineering and STEM career paths. A second component of the surveys asks questions regarding student’s most and least favorite aspects of the camp, suggested improvements for the camp, and who (if applicable) made their camp experience most enjoyable. These were separated by question and analyzed to determine the explicit theme of each response.
These survey results were collected blindly to the camp coordinators through the college of engineering and the results were aggregated and dispersed to respective camp leaders later in the summer. Student responses are completely anonymous. Here, these survey responses are used to gather brief and concluding snapshots of any prevailing thoughts and experiences that may be relevant to student STEM identity formation.
6. Conclusions
Recall that the purpose of this study was to show how the incorporation of ethics and social awareness into a standard summer engineering curriculum impacts the engineering identity formation of pre-college girls. Drawing on the Framework for Quality K–12 Engineering Education (QEE) and the Socioscientific Issues (SSI) framework to highlight the need for and role of ethics and humanities in STEM-based curriculums, and qualitative data, this important question is answered. Secondarily, these two frameworks provide a blueprint for how a synergy between STEM and the humanities may be put into tangible practice and for how we may expect shifts in student’s perspectives through humanities incorporation. Results of this study suggest several key conclusions.
First, the incorporation of humanities into a traditional STEM curriculum will diversify the lens and viewpoints from which STEM is discussed, resulting in the subsequent introduction of more social and emotional connection points for young women who wish to pursue subjects in STEM. Recall how students who participated in the socio-ethics enhanced camp model described their science in terms atypical to traditional STEM culture (
Figure 3) compared to students who participated in a standard model STEM camp (
Figure 2). This finding aligns favorably with the practice of normative and non-normative science [
49] and demonstrates that secondary humanities-based considerations must be practiced and learned before they can be unconsciously implemented in the field. In other words, students in this STEM context must be taught to consider social and ethical issues before they should be expected to implement those considerations on their own.
Second, social and emotional connection-points to subject content are critical to effectively engage young women in traditional STEM disciplines. Historical data shows that the life sciences have been particularly successful at recruiting the interests of women and the theories as to why that is the case are many; however, assertions that women tend to connect to and rationalize their STEM work differently than men [
25] are affirmed here. As demonstrated in
Table 1 and
Table 2 and
Figure 4 and
Figure 5, in both the standard and socio-ethics enhanced camp models, campers expressed their favorite camp experiences in both social-emotional and content specific terms; however, in the socio-ethics enhanced camp which is most like traditional life sciences there was an overwhelming citing of social and emotional experiences as most memorable to the camp week. As a follow-up to this, it would be interesting to see if young men also cite such social and emotional experiences in a similar camp setting, or not, and if these expressions of experiences age dependent.
Lastly, regardless of specific STEM discipline interest, an equitable science social system structure and ample opportunities for success are a necessity for young women interested in pursuing disciplines in STEM. Though differences existed regarding how both groups communicated their STEM interests (social-emotional vs content specific), strong commonalities existed in their affinity towards camp counselors and their necessary interactions with said counselors. Campers’ statements affirm the importance of the presence of like role models and non-threatening structural environments for the productive formation of their STEM identity [
21]. Counselors in this context were also female STEM majors who shared many social contact hours with campers throughout the camp week. These interactions between campers and counselors played a large role in shaping camper perceptions of the social structural environment and culture of practicing STEM.
Finally, this work sets the stage for some potential future research. Given that women connect to their STEM work differently than men and therefore would seem to be more drawn towards the introduced social-emotional connections into traditional STEM curriculum, it would be interesting to see how the interest in and perceptions of STEM for young men are impacted by the introduction of social and ethics curriculum. I posit that the earlier that humanities-based narratives are introduced into STEM, the greater impact it will have on the culture and structural systems of STEM, thus supporting the development of equitable science social systems. Another potential subject of interest could look at what specific science environmental structures minorities migrate towards under circumstances where they are socially welcomed and not. These things could all push our practice of STEM toward fostering a more equitable science culture. It is possible and arguably more human for a greater synergy to exist between STEM and the Humanities.
