A New Computational Intelligence Approach To Predicting The Machined Surface Roughness In Metal Machining, Ning Fang, P. Srinivasa Pai

Engineering Education Faculty Publications

Machined surface roughness is an important parameter used in the evaluation of the surface integrity of machined parts and components. This paper proposes a new computational intelligence approach to predicting the machined surface roughness in metal machining. In this approach, wavelet packet transform (WPT) is incorporated into artificial neural networks (ANN) to develop two ANN models for predicting average roughness Ra and root-mean-square roughness Rq, respectively. Each model has eight inputs, including the cutting speed, the feed rate, energy of wavelet packets for three cutting force components, and energy of wavelet packets for three cutting vibration components. Forty-five machining experiments …

Hidden Curriculum Awareness: A Comparison Of Engineering Faculty, Graduate Students, And Undergraduates, Idalis Villanueva, Marialuisa Di Stefano, Laura Gelles, Katherine Youmans

Engineering Education Faculty Publications

In order for an engineering academic body (e.g., facultyand students) to navigate their surroundings, they must first become aware of the hidden curriculum around them. Hidden curriculum represents how particular assumptions, values, attitudes, and beliefs about schooling manifests in practice. When understood, these types of lessons or messages allow students, faculty, and staff to more easily navigate the academic and socio-political customs needed for success.

As part of a larger study, a total of 224 participants across 57 engineering programs in the United States and Latin America were asked to comment on a survey that asked respondents about the expectations …

Uncovering The Hidden Factors That Could Compromise Equitable And Effective Engineering Education, Idalis Villanueva, Janice Mejia, Renata A. Revelo

Engineering Education Faculty Publications

Literacies are central to the social and cultural practices that are intertwined with identities, who gets to participate in engineering, and the knowledge that is valued in the discipline. However, identifying these literacies is not a straightforward process for engineering faculty. The purpose of this workshop is to help engineering faculty identify equity- oriented literacies that challenge hidden curriculum frameworks in engineering and influence engineering identity formation.

Critical Theoretical Frameworks In Engineering Education: An Anti-Deficit And Liberative Approach, Joel A. Mejia, Renata A. Revelo, Idalis Villanueva, Janice Mejia

Engineering Education Faculty Publications

The field of engineering education has adapted different theoretical frameworks from a wide range of disciplines to explore issues of education, diversity, and inclusion among others. The number of theoretical frameworks that explore these issues using a critical perspective has been increasing in the past few years. In this review of the literature, we present an analysis that draws from Freire’s principles of critical andragogy and pedagogy. Using a set of inclusion criteria, we selected 33 research articles that used critical theoretical frameworks as part of our systematic review of the literature. We argue that critical theoretical frameworks are necessary …

“There Is Never A Break”: The Hidden Curriculum Of Professionalization For Engineering Faculty, Idalis Villanueva, Taya Carothers, Marialuisa Di Stefano, Md. Tarique Hasan Kahan

Engineering Education Faculty Publications

The purpose of this exploratory special issue study was to understand the hidden curriculum (HC), or the unwritten, unofficial, or unintended lessons, around the professionalization of engineering faculty across institutions of higher education. Additionally, how engineering faculty connected the role of HC awareness, emotions, self-efficacy, and self-advocacy concepts was studied. A mixed-method survey was disseminated to 55 engineering faculties across 54 institutions of higher education in the United States. Quantitative questions, which centered around the influences that gender, race, faculty rank, and institutional type played in participants’ responses was analyzed using a combination of decision tree analysis with chi-square and …

From Deficit Thinking To Counter Storying: A Narrative Inquiry Of Nontraditional Student Experience Within Undergraduate Engineering Education, Angela Minichiello

Engineering Education Faculty Publications

This paper reports on narrative inquiry research conducted with nontraditional undergraduates as they pursued a common goal of becoming engineers. Participants were enrolled in a two-year engineering transfer program offered in the evenings, via synchronous broadcast distance instruction, by a public, land-grant university situated in the western United States. The purpose of the research was to understand the experiences of nontraditional students during the two-year program, which they accessed at regional campuses within or near their local communities, and later as they transitioned to the four-year university campus located in another city away from these communities. In this paper, personal, …
