Chasteen, Stephanie V.; Wilcox, Bethany; Caballero, Marcos D.; Perkins, Katherine K.; Pollock, Steven J.; Wieman, Carl E. – Physical Review Special Topics - Physics Education Research, 2015
In response to the need for a scalable, institutionally supported model of educational change, the Science Education Initiative (SEI) was created as an experiment in transforming course materials and faculty practices at two institutions--University of Colorado Boulder (CU) and University of British Columbia. We find that this departmentally…

Wilcox, Bethany R.; Pollock, Steven J. – Physical Review Special Topics - Physics Education Research, 2015
The Dirac delta function is a standard mathematical tool that appears repeatedly in the undergraduate physics curriculum in multiple topical areas including electrostatics, and quantum mechanics. While Dirac delta functions are often introduced in order to simplify a problem mathematically, students still struggle to manipulate and interpret them.…

Pepper, Rachel E.; Chasteen, Stephanie V.; Pollock, Steven J.; Perkins, Katherine K. – Physical Review Special Topics - Physics Education Research, 2012
We discuss common difficulties in upper-division electricity and magnetism (E&M) in the areas of Gauss's law, vector calculus, and electric potential using both quantitative and qualitative evidence. We also show that many of these topical difficulties may be tied to student difficulties with mathematics. At the junior level, some students…

Chasteen, Stephanie V.; Perkins, Katherine K.; Beale, Paul D.; Pollock, Steven J.; Wieman, Carl E. – Journal of College Science Teaching, 2011
Faculty often wish to devote time and resources to improve a course to be more in line with principles of how people learn but are not sure of the best path to follow. We present our tested approach to research-based course transformation, including development of learning goals, instructional materials based on student difficulties, and…

Pollock, Steven J.; Finkelstein, Noah D.; Kost, Lauren E. – Physical Review Special Topics - Physics Education Research, 2007
Previous research [Lorenzo et al., Am. J. Phys. 74, 118 (2006)] demonstrated that the difference in performance between male and female students can be reduced and even eliminated, in consistent fashion, by using interactive engagement techniques in the introductory physics classroom. The present paper describes similar studies in a different,…
