My main professional focus is on the design, implementation and evaluation of computer-based learning environments. The courses I teach are all variations on that theme: ED 834 is a doctoral class about the design of learning systems; EDTEC 570 focuses on the development of WebQuests and lessons wrapped around telecollaboration, databases and software; and EDTEC 670 is all about the design of educational games and simulations. I just ended a long stint of coordinating the nine sections of EDTEC 470 class taken by pre-service teachers. I also guided curriculum development for the Triton and Patterns Projects, Challenge Grants of the San Diego Unified School District that are now complete.
