Will i succeed in engineering? Using expectancy-value theory in a longitudinal investigation of students' beliefs

Abstract

This multi-case study qualitatively and inductively examines undergraduate engineering students' expectancies for success as engineers as well as how these expectancies change from freshmen through senior years at a public technical institution in the western United States. The theoretical framework is expectancy-value theory, developed by Eccles, Wigfield and their colleagues, which suggests that achievement-related choices result from the intersection of an individual's expectancy for success in a given situation and the value they assign to success in that situation. Longitudinal data analysis, based on semi-structured interviews conducted over four years with four students (two male and two female), addresses the following research questions: How do students characterize success in their given engineering field? How do these characterizations develop and change with time? Do students believe they have these characteristics that they define as important to success? Results show success beliefs do change over the four years. First-year students give generic responses that are not specific to engineering. By the third and fourth year, students who have interned have: 1) more specific, concrete beliefs about success that are grounded in personal, authentic experiences, and 2) can more accurately assess their abilities citing specific evidence. Additionally, the data demonstrate that students who lack confidence in skills they perceive to be important to successful engineers can still have a positive expectancy of success in engineering. The results generally support Eccles' model with one modification. © American Society for Engineering Education, 2008.
