Katherine Cheng is a doctoral student at the Sanford School of Social and Family Dynamics at Arizona State University. She is interested in understanding the origins of students' academic performance and their well-being. Kat completed her BS and MA in Psychology, and is currently majoring in Family and Human Development. Her research emphasizes a multi-disciplinary perspective, including bringing together constructs from the fields of motivation, human development, and biopsychology. Her research is dedicated to understanding the links between students' emotions, emotion regulation, attention, and future-oriented motivation with respect to optimal school performance and physiological well-being.
Understanding Engineering Students Stress and Emotions during an Introductory Engineering courseAlthough recent literature in engineering education has focused on student enjoyment of coursework and its influence on student retention, 1-3 very little research has incorporated theoretical frameworks which identify the specific roles that student beliefs and emotions play in course engagement. 4 To supplement self-report measures when assessing students' emotions in learning environments, many educational researchers have attempted to tie physiological responses to students' beliefs, affects, and motivation -including those that utilized self-reported bodily responses, brain imaging, galvanic skin responses, and cardiovascular responding. [5][6][7][8][9][10][11][12] Some researchers in education, but not many, have utilized the biological marker salivary cortisol to indicate students' stress and emotional states.
13, 14Notably, a multi-method interdisciplinary approach in engineering educational research has yet to be established. Interdisciplinary work, however, is crucial for incorporating theories with practice in education, since the inclusion of biomarkers in emotionand-motivation-related research could provide support for current theory and its application, to enhance learning and course engagement. Using salivary cortisol as a tool in engineering educational research allows us to take advantage of saliva's sampling convenience, and its informative nature that is not readily affected by social desirability, reactivity, and memory. In essence, the current study aimed to address two gaps in the engineering educational literature: 1) to bridge research in engineering students' beliefs and emotions with theory, and 2) to explore an interdisciplinary approach to understanding how engineering students engage in their courses using salivary cortisol.
Theoretical frameworksThe field is gravitating towards an understanding and acceptance of the roles that motivation, beliefs, and emotions play in engineering education.4, 15 However, theory-based empirical research is much needed in order to tease apart the mechanisms of how each psychological construct is associated with another. In the current study, we used two motivational frameworks: Control-Value Theory (CVT) 16,17 and Future Time Perspective Theory (FTPT). 18 CVT addr...
