Mathematics Education Expertise

Teacher education  (elementary and secondary, preservice and inservice), curriculum writing, ethnomathematics, developing and using technology for math education

Writing Projects

In progress: Measuring the World, co-author David Dennis. A textbook for a year-long course in mathematics for elementary teachers. This book is undergoing pilot testing at CSUSB through 2012.

Technology in Math Education. This is a “textbook” (exposition and problems) for a 1-quarter or 1-semester course for future secondary math teachers. Covers dynamic geometry software, spreadsheets, and computer algebra systems.

Mathematical Intentions. (This website) The history of our secondary math curriculum. Lecture series (podcasts) by David Dennis; lecture notes/problem sets by Dennis and Addington; applets by Addington.
