Title: Pilot Study: Investigating EEG Based Neuro-Responses of Engineers via a Modified Alternative Uses Task to Understand Creativity
Assessing creativity is not an easy task, but that has not stopped researchers from exploring it. Because creativity is essential to engineering disciplines, knowing how to enhance creative abilities through engineering education has been a topic of interest. In this paper, the event related potential (ERP) technique is used to study the neural responses of engineers via a modified alternative uses task (AUT). Though only a pilot study testing two participants, the preliminary results of this study indicate general neuro-responsiveness to novel or unusual stimuli. These findings also suggest that a scaled-up study along these lines would enable better understanding and modeling of neuroresponses of engineers and creative thinking, as well as contribute to the growing field of ERP research in the field of engineering.  more » « less

  1. WIP: Assessing the Creative Person, Process and Product in Engineering Education This evidence-based practice paper provides guidance in assessing creativity in engineering education. In the last decade, a number of vision statements on the future of engineering education (e.g. Educating the Engineer of 2020, the ASCE Body of Knowledge) point to the fact that creativity is essential to engineering innovation; it is regarded as an important attribute in the education of engineers in order to meet the most urgent national challenges and to drive economic growth in the new millennium. Yet studies suggest that engineering students’ creative skills are being left underdeveloped or diminish over the course of their studies, or worse, that students who consider themselves to be creative are being driven away from engineering as a chosen field. On the surface, creativity skills are perceived as difficult to utilize in the engineering classroom, primarily due to the didactic nature of science and engineering instruction. Assessing the product of open ended or ill-structured assignments remains a difficult task as well. This study examines available assessments for creativity that are founded in three of the Four Ps of creativity: person, process, product (the fourth P, press, is not considered in this work.) The intent is to identify verified metrics that can be used to quantify creativity with a particular look to whether the metrics are appropriate for creativity, particularly as they pertain to the science and engineering domains. These metrics are examined for applicability to science and engineering, ease of administration and completion, expertise required to score, cost to administer, and time required to administer. Rather than determining the “best” metrics, this examination will provide guidelines for engineering educators and researchers interested in creativity for selecting appropriate metrics to be used in classrooms and research studies based on metric attributes.

    Engineering programs, in general, do not explicitly address the need to enhance divergent thinking. To a certain extent this is due to a lack in knowledge on the cognitive and neural mechanisms underlying divergent thinking, and creative ideation more generally. We hypothesize that we can help enhance our students’ divergent thinking and creative processing outcomes by investigating the impacts of carefully selected methods and tools enabled by developments in the robust analysis of engineering ideation performance, and neurocognitive responses to creativity. In this paper, we present an experiment using the Event-Related brain Potentials (ERP) technique and creative language use (funded by Core R&D Programs). More specifically, we collected ERP responses to literal, nonsense, and novel metaphorical sentences that were either referring to engineering knowledge or general knowledge, testing engineering and non-engineering students. Following Rutter et al. [1], sentences differed in verb only and had been classified in prior sentence norming studies as highly unusual and highly appropriate (novel metaphors), low unusual and highly appropriate (literal sentences), and highly unusual and low appropriate (nonsense sentences). Participants read sentences while their EEG was recorded, and after reading the sentence made judgments about its unusualness and appropriateness. The findings indicate that prior knowledge modulates novel metaphor processing at the stage of lexico–semantic access, indexed by the amplitude of N400 component. Specifically, N400 amplitudes to novel metaphorical sentences are significantly reduced and pattern with literal sentences in engineers; in nonengineers, by contrast, we observed increased N400 amplitudes to novel metaphorical sentences that pattern with anomalous sentences. This mirror effect on the N400 corroborates recent findings demonstrating a strong impact of prior experience and expertise on meaning ambiguity resolution, which may in turn have implications for creative cognition.

  3. Creative self-efficacy (CSE) was studied in connection to beliefs about creativity. CSE is one’s belief in their own creative potential. The belief that creativity can improve was discussed as a “Growth Creativity Mindset” (GCM), and the belief that creativity cannot improve was discussed as a “Fixed Creativity Mindset” (FCM). Creativity within engineering has been described as crucial to the field, and as an aspect that is appealing to women engineers. Undergraduate women engineering students local to the Philadelphia area volunteered to take a survey of CSE and beliefs about creativity. Quantitative data analysis showed that an increase in GCM likely results in an increase in CSE for students with higher than average GPA. A change in CSE had no effect on FCM. Interviews were conducted with 15 survey respondents with different levels of CSE who met criteria for success in the engineering major (2.5 GPA or above and successful completion of calculus II). Synthesis of the quantitative and qualitative data revealed that interview participants had similar lived experiences that lead them to a level of success in the engineering major, but different lived experiences that distinguished them with respect to CSE level. All participants were exposed to project based learning (PBL), had strong personal influences, exhibited perseverance in overcoming struggles, and described their negative perceptions of engineering before entering the major. Participants with all levels of CSE highlighted their own creativity with respect to the performing and visual arts, before reflecting on innovation as creative. Most participants with low CSE described their lack of creativity in the arts. They also discussed being “intimidated” by negative classroom experiences more than their peers with higher levels of CSE. Those with low CSE were also exposed to more engineering centered experiences in high school, and most had a parent who worked in the profession. It is expected that this research will provide a more comprehensive understanding of CSE, perceptions of engineering as a creative field, and the educational reform needed that connects creativity to engineering in an atmosphere that welcomes diversity.

  4. Engineering is a creative profession where diverse perspectives of both men and women are crucial to the field. The importance of better understanding the pipeline of female students into engineering, and the path to their success in the major is evident. In 2017, women comprised approximately 20% of engineering graduates, up from 18% in 1997, and 15% never entered the engineering workforce. In 2019, women comprised 48% of the workforce, 34% of the STEM workforce, and only 16% of practicing engineers, a 3% increase from 2009. In an effort to better understand these disparities, this mixed methods research investigated the creative self-efficacy (CSE) of women engineering majors and their beliefs about creativity in relation to lived experiences and explores the research question: In what ways do undergraduate women engineering students describe their creativity and how their lived experiences influenced their decision to major in engineering? The researchers investigated the lived experiences of women engineering students before they entered the engineering major in relation to the way they described themselves as creative. A survey of CSE and beliefs about creativity was administered to 121 undergraduate women engineering students who volunteered for this study. Interviews were conducted of 15 participants selected from survey results with different levels of CSE who met the researcher’s criteria for success in the engineering major. The findings of this study lead to several conclusions: (1) students’ descriptions of themselves as creative corresponded more with the arts than to innovation in engineering; (2) students who described themselves as less creative: (a) had a lower level of CSE; (b) had a greater exposure to engineering in high school through engineering-centered courses and clubs; (c) had a family member who worked in the profession; (d) described more negative classroom experiences at all educational levels that involved intimidation, isolation, and gender-bias.

  5. Design for manufacturing provides engineers with a structure for accommodating the limitations of traditional manufacturing processes. However, little emphasis is typically given to the capabilities of processes that enable novel design geometries, which are often a point of focus when designing products to be made with additive manufacturing (AM) technologies. In addition, limited research has been conducted to understand how knowledge of both the capabilities (i.e., opportunistic) and limitations (i.e., restrictive aspects) of AM affects design outcomes. This study aims to address this gap by investigating the effect of no, restrictive, and both, opportunistic and restrictive (dual) design for additive manufacturing (DfAM) education on engineering students’ creative process. Based on the componential model of creativity [1], these effects were measured through changes in (1) motivation and interest in AM, (2) DfAM self-efficacy, and (3) the emphasis given to DfAM in the design process. These metrics were chosen as they represent the cognitive components of ‘task-motivation’ and ‘domain relevant skills’, which in turn influence the learning and usage of domain knowledge in creative production. The results of the study show that while the short (45 minute) DfAM intervention did not significantly change student motivation and interest towards AM, students showed high levels of motivation and interest towards AM, before the intervention. Teaching students different aspects of DfAM also resulted in an increase in their self-efficacy in the respective topics. However, despite showing a greater increase in self-efficacy in their respective areas of training, the students did not show differences in the emphasis they gave to these DfAM concepts, in the design process. Further, students from all three education groups showed higher use of restrictive concepts, in comparison to opportunistic DfAM.
