Title: Analysis Without Data: Teaching Students to Tackle the VAST Challenge
The VAST Challenges have been shown to be an effective tool in visual analytics education, encouraging student learning while enforcing good visualization design and development practices. However, research has observed that students often struggle at identifying a good "starting point" when tackling the VAST Challenge. Consequently, students who could not identify a good starting point failed at finding the correct solution to the challenge. In this paper, we propose a preliminary guideline for helping students approach the VAST Challenge and identify initial analysis directions. We recruited two students to analyze the VAST 2017 Challenge using a hypothesis-driven approach, where they were required to pre-register their hypotheses prior to inspecting and analyzing the full dataset. From their experience, we developed a prescriptive guideline for other students to tackle VAST Challenges. In a preliminary study, we found that the students were able to use the guideline to generate well-formed hypotheses that could lead them towards solving the challenge. Additionally, the students reported that with the guideline, they felt like they had concrete steps that they could follow, thereby alleviating the burden of identifying a good starting point in their analysis process.  more » « less

  1. In preparing engineering students for the workplace, capstone classes provide unique opportunities for students to develop their professional identities and learn critical skills such as engineering design, teamwork, and self-directed learning (Lutz & Paretti). But while existing research explores what and how students learn within these courses, we know much less about how capstone courses affect students’ transitions into the workplace. To address this gap, we are following 62 new graduates across 4 institutions during the participants’ first 12 weeks of work. Participants were drawn from 3 mechanical engineering programs and one general engineering program. Women were intentionally oversampled in the study, with 29 participants identifying as female. Weekly surveys were used to collect quantitative data on what types of workplace activities participants engaged in (e.g., team meetings, project budgeting, CAD modeling, engineering calculations) and qualitative data on what challenges they experience in their early work experience. In this paper, we present a descriptive analysis of the data to identify patterns across participants. Preliminary analysis of the quantitative data suggests that the most common activities for our participants were team meetings and project planning (mentioned by >70% of participants) compared to formal presentations and project budgeting (mentioned by <30% of participants). Preliminary analysis of the qualitative data suggests that participants’ most challenging experiences clustered into two dominant groups: 1) self-directed learning, and 2) teamwork and communication. The results are intended to inform both capstone faculty and industry to identify areas of strength within current practices and areas for improvement in course design and structure and/or in industry onboarding practices.

  2. CONTEXT The need to better prepare students for the engineering workplace is a long-standing and on-going concern among engineering educators. With the aim of addressing gaps in preparation, the number of new work- and practice-based programs is growing. Identifying the first and most significant challenges recent graduates face in the workplace can contribute new insights into how students could be better prepared for the school-to-work transition. PURPOSE In order to better understand the transition from school to work, this paper presents findings from the first year of a five-year longitudinal study exploring the experiences and career trajectories of early career engineers. The specific question addressed in this paper is: What was the biggest challenge civil engineers experienced during their first year in the workplace? METHODS Eighteen early career civil engineers participated in semi-structured interviews in May of 2019. Participants were recruited from national and local listservs in the United States. None worked in the same office, although two worked for the same company in different offices. They were asked a range of questions related to their experiences transitioning into their careers. For this paper, responses pertaining to the biggest challenge question were analysed through open coding to determine if any themes could be identified in participants’ responses. OUTCOMES Participants were asked about the biggest challenge they had encountered since starting their job. Their responses covered a very wide range of issues. There were three themes of note that appeared in at least four different participants’ responses. They were: 1) interdependence, 2) new practices and material, and 3) negative interactions. 1 and 2 were cited by both men and women; 3 was only cited by women. CONCLUSIONS In addition to providing insights into job readiness that engineering educators can address, the findings speak to several aspects of organizational socialization. Most participants’ biggest challenges (in the form of interdependence and new practices and materials) were related to “learning & adaptation.” Challenges related to “relationship building” and “work group socialization tactics” (in the form of negative interactions) were only the biggest challenges for women, not men. However, negative interactions also extended beyond factors accounted for in current models of organizational socialization, and should be accounted for in revised models. KEYWORDS Early career, job readiness, organizational socialization

  3. Several studies have shown that underrepresented minorities (URM) (African Americans, Native Americans, Pacific Islanders, and Latinos) are more likely to drop out of engineering doctorate programs before graduation compared to international and majority students. In addition, transitioning into the doctoral programs without having a good understanding of what it entails can make the PhD experience difficult. To address this issue, a team of researchers from four US universities developed a project called “the Rising Doctoral Institute (RDI)’’. One of the research goals of this project is to better understand how factors in the academic system interact dynamically to influence (i.e., support or hinder) incoming URM students’ access, success, persistence, and retention in engineering doctoral programs. To accomplish this goal, we will use a comprehensive analysis approach known as System Dynamic Model (SDM). This work-In-Progress article represents the starting point to develop this model and its overall goal is to conduct a systematic literature review to identify the factors in the academic system that impact URM students’ experience in doctoral engineering programs. We followed a process suggested by Okoli and Schabram [1] which consists of four major steps. The first step is presenting the purpose of the literature review, protocol, and training. The second step consists of selecting the literature and practical screen. The next step is the quality appraisal and data extraction. Finally, the analysis of findings and writing the review. By identifying the factors and the relation between them, we could help ensure a more diverse and equitable STEM education. Although some external factors can affect students’ access, success, persistence and retention in engineering PhD programs, this study is limited to exploring the factors and interactions within the academic system that can potentially impact the successful experience of underrepresented minorities in PhD programs in engineering such as Advisor-Advisee Relationship, Student’s Experience, Academic Support and Faculty-Students Interaction

  4. Purpose: Identifying the inequities underrepresented groups face in undergraduate engineering education and addressing these inequities is commonly in the hands of faculty and staff rather than the students who experience them firsthand. Seeking to shift away from this dynamic and empower students to name and challenge the oppression they face, we launched the Justice, Equity, Diversity, and Inclusion (JEDI) Ambassador Program at a large Hispanic-Serving Institution in the Southeastern United States. JEDI is a co-curricular program that employs undergraduate engineering students to engage in justice, equity, diversity, and inclusion projects with the guidance of a graduate student or university support staff mentor. In this paper, we investigate the impact and limitations of this attempt at liberatory pedagogy through analyzing exit interviews with the alumni from the first two years of the program. Framework: This study is informed by liberative pedagogy, which facilitates critical consciousness and supports students in bringing their whole selves to a learning space to expand their critical capacities. One of the primary goals in creating JEDI was to provide engineering students space to realize and name the oppression they face and support them in designing their own projects that seek to challenge oppression. This paper investigates our attempt at operationalizing liberatory pedagogy through JEDI. Methods: The first author conducted 80–150-minute semi-structured interviews with program alumni. The interview protocol was informed by constructs from liberative pedagogy, focusing on participants' experiences in the program. The first author utilized thematic coding to identify salient themes across the interviews. Results: The analysis of the interview data revealed several successes and shortcomings related to operationalizing liberative pedagogy. One theme related to the successes was that participants expressed that JEDI offered a safe, welcoming environment in which they could embrace their marginalized identities and freely express their ideas. This finding, along with other themes that will be discussed in the paper, speak to the positive impact of the program. However, one theme related to shortcomings was that participants spoke extensively about the positive impact JEDI had on them as individuals, but they did not express that they saw their projects as having a significant external impact. We see this as a limitation regarding the program engaging the students in liberatory praxis within their local communities. Significance: Findings from this study provide insight into the impact liberative pedagogy has on engineering students and the challenges of operationalizing liberative pedagogy in a formal university context. These results could aid the engineering education community as we continue to search for ways to support and empower students.

  5. Viral social media challenges have erupted across multiple social media platforms. While social media users participate in prosocial challenges designed to support good causes, like the Ice Bucket Challenge, some challenges (e.g., Cinnamon Challenge) can also potentially be dangerous. To understand the influential factors, experiences, and reflections of young adults who participated in a viral social media challenge in the past, we conducted interviews with 30 college students (ages 18-27). We applied behavioral contagion theory as a qualitative lens to understand whether this theory could help explain the factors that contributed to their participation. We found that behavior contagion theory was useful but not fully able to explain how and why young social media users engaged in viral challenges. Thematic analyses uncovered that overt social influence and intrinsic factors (i.e., social pressure, entertainment value, and attention-seeking) also played a key role in challenge participation. Additionally, we identified divergent patterns between prosocial and potentially risky social media challenges. Those who participated in prosocial challenges appeared to be more socially motivated as they saw more similarities between themselves and the individuals that they observed performing the challenges and were more likely to be directly encouraged by their friends to participate. In contrast, those who performed potentially risky challenges often did not see similarities with other challenge participants, nor did they receive direct encouragement from peers; yet, half of these participants said they would not have engaged in the challenge had they been more aware of the potential for physical harm. We consider the benefits and risks that viral social media challenges present for young adults with the intent of optimizing these interactions by mitigating risks, rather than discouraging them altogether.
