- At UNL:
- Course development:
- Math 350 Modern Geometry: Complete course redesign to align material with the National/Nebraska teaching standards for the associated high school geometry topics. The emphasis was changed to showing the students why - and when - the standard results of high school geometry are true, and incorporated significant component working with software such as Geometer's Sketchpad for hands-on exploration of Euclidean and hyperbolic geometry.
- Math 471 Undergraduate Topology: New course designed to be accessible to students with a variety of abilities and backgrounds. The material covered includes some basics of point-set topology, but also combinatorial and geometric aspects of topology that allow the students to use pictures and other ``concrete'' methods to study spaces.
- Math 911 Topics in Group Theory: Several different courses have been developed under this title, with half or full semester modules in areas including: Growth of groups, poly-properties of groups, geometric group theory, and homology of groups.
