The ability of future engineering professionals to solve complex real‐world problems depends on their design education and training. Because engineers engage with open‐ended problems in which there are unknown parameters and multiple competing objectives, they engage in fuzzy decision‐making, a method of making decisions that takes into account inherent imprecisions and uncertainties in the real world. In the design‐based decision‐making field, few studies have applied fuzzy decision‐making models to actual decision‐making process data. Thus, in this study, we use datasets on student decision‐making processes to validate approximate fuzzy models of student decision‐making, which we call data‐enabled cognitive modeling. The results …

An engineering workforce of sufficient size and quality is essential for addressing significant global challenges such as climate change, world hunger, and energy demand. Future generations of engineers will need to identify challenging issues and design innovative solutions. To prepare young people to solve big and increasingly global problems, researchers and educators need to understand how we can best educate young people to use engineering design thinking. In this paper, we explore virtual internships, online simulations of 21st-century engineering design practice, as one method for teaching engineering design thinking. To assess the engineering design thinking, we use epistemic network analysis …
A Grounded Qualitative Analysis Of The Effect Of A Focus Group On Design Process In A Virtual Internship, Matthew R. Markovetz, Sean Sullivan, Renee M. Clark, Zachari Swiecki, Golnaz Arastoopour Irgens, David W. Shaffer, Naomi C. Chesler, Cheryl A. Bodnar

A key component associated with the development of an entrepreneurial mindset is the ability to understand customerneeds and consider this when developing a product. This study sought to understand whether the inclusion of a customerfocus group as part of a virtual internship created any differences in the design processes of sophomore engineeringstudents (114 students). The Nephrotex virtual internship requires that students design a dialysis membrane by optimizinga selection of four components: membrane polymer, polymerization process, processing surfactant, and carbon nanotubepercentage. We found that sophomores who engaged in a focus group during the virtual internship Nephrotex showed(statistically) equal focus on cost …

Engineering product design requires both technical aptitude and an understanding of the non-technical requirements in the marketplace, economic or otherwise. Engineering education has long focused on the technical side of product design, but there is increasing demand for market-aware engineers in industry. Market-awareness and customer-focus are also associated with entrepreneurship, which has been given increased focus in engineering education. A common tool for gauging customer interest in industry is the focus group. Herein we examine the effect of customer voice as presented in a focus group for influencing engineering product design generated by students as part of the virtual internship …

Analyses of learning based on student discourse need to account not only for the content of the utterances but also for the ways in which students make connections across turns of talk. This requires segmentation of discourse data to define when connections are likely to be meaningful. In this paper, we present an approach to segmenting data for the purposes of modeling connections in discourse using epistemic network analysis. Specifically, we use epistemic network analysis to model connections in student discourse using a temporal segmentation method adapted from recent work in the learning sciences. We compare the results of this …

Increasingly, first-year engineering curricula incorporate design projects. However, the faculty and staff effort and physical resources required for the number of students enrolled can be daunting and affect the quality of instruction. To reduce these costs, ensure a high quality educational experience, and reduce variability in student outcomes that occur with individual design projects, we developed a simulation of engineering professional practice, NephroTex, in which teams of students are guided through multiple design-build-test cycles by a mentor in a virtual internship. Here we report on the design process for the virtual internship and results of testing with first-year engineering students …
