Developing Skeptical ReverenceThe tendency of K-12 students to view mathematics as an activity that only takes place inschools has been hypothesized to cause educational trouble, including a lack of studentmotivation and thus less learning, and students’ inability to apply what mathematics they dolearn to solving problems outside of school or in other subjects. Many adults have not outgrownthe idea that mathematics is not really useful in their everyday activity or work. Despiteengineering’s reputation as math-intensive, even the engineering community debates the amountof (school) mathematics individual engineers actually need to know to perform everyday work,especially in light of the increasing role of computers.That debate inspired a prior study, in which I showed that a key component of the expertise ofcivil engineers was their ability to use mathematics to serve their problem-solving purposes.This required a keen understanding of the powers and limitations of formal and informalmathematical tools. Only rarely could mathematical procedures be applied wholesale (as theyusually are in school); engineering expertise included flexibly selecting and adapting—occasionally even overriding—mathematical procedures to model real phenomena. I termed thissomewhat hybrid disposition towards mathematics skeptical reverence: a fine balance betweenseeing mathematics as an indispensible tool and understanding its limitations.The current study investigates how engineers develop their perspective on the relationshipbetween mathematics and engineering and this disposition of skeptical reverence. This questionis critical for engineering education: Young engineers who see little connection betweenmathematics and engineering, who perhaps believe that “real engineers don’t use math,” wouldseem unlikely to learn to use the mathematics well. Yet, those who view engineering as theroutine application of known mathematical procedures or believe that mathematics serves as theultimate authority for engineering decisions will be equally hobbled in their efforts to attainengineering expertise.This study draws on the sociocultural research tradition that frames learning as a personaltransition within and across communities of practice. I targeted individuals at various stages ofthe transition between the communities of practice of school and engineering work, and Iexplored their evolving perceptions of the role of mathematics in engineering. Assuming themathematical disposition of skeptical reverence is productive and desirable for engineers, Iaimed to back-map the development of that disposition, through interviews, engineering-courseobservations, and “think-aloud” problem-solving sessions. The greater study involved 20participants, ranging from freshmen in an undergraduate civil-engineering program to veterancivil engineers and instructors. This paper focuses on the development of the 10 students: 2-3 ateach of the four years of the undergraduate program. Using qualitative-data-analysis methods, Icharacterize the students’ mathematical dispositions and how these differed among students indifferent years of the program. I discuss implications for engineering education as well as K-12.
