Abstract

"Surface area to volume ratio" has been widely acknowledged as one of the "big ideas" of nanoscience, as it lays the foundation for understanding size-dependent properties that characterize nanoscale science and technology. Though seemingly an easy concept, students are reported to have difficulty grasping this concept, particularly its connection to property change. We report in this paper our effort in unpacking students' conceptions of this concept in the context of an undergraduate engineering course. Guided by the "Construct-Centered Design" (CCD) framework, we conducted detailed unpacking of student conceptions, and developed corresponding assessment items in an iterative process, which not only revealed an interesting range of conceptions, but also yielded several effective assessment items. The identified conceptions are summarized in a preliminary typology, which includes three major types of conceptions distinguished by seven aspects of variation. Practical implications of the typology and the use of the CCD process are discussed.
