Integrating computation and simulation into the undegraduate physics curriculum

At Northern Arizona University, we have been integrating computation and simulation into the curriculum at all levels. We hope to achieve a number of objectives: (i) increase student retention during the first three semesters of the program, (ii) train students in this ``third branch'' of science, (iii) provide students with scientific computing skills, (iv) expand the coverage of the upper-division course content. I will discuss two courses required during the freshman and sophomore years and how computation and simulation is integrated into the upper-division courses. The percieved successes and remaining shortcomings of the current curriculum will addressed.
