With this conclusion in mind, this paper investigates a particular calculus topic that is used frequently in science and engineering: the definite integral. The results of this study demonstrate that certain conceptualizations of the definite integral, including the area under a curve and the values of an anti-derivative, are limited in their ability to help students make sense of contextualized integrals. In contrast, the Riemann sum-based ``adding up pieces" conception of the definite integral (renamed in this paper as the ``multiplicatively-based summation" conception) is helpful and useful in making sense of a variety of applied integral expressions and equations. Implications for curriculum and instruction are discussed.}, msc2010 = {I55xx (M55xx)}, identifier = {2015d.00785}, }
