Astronomy, like all sciences, evolves; the skills that a student must acquire must also evolve. The majority of astronomy majors do not become professional astronomers; they do, however, find employment in a variety of STEM fields.  Data analysis and numerical computation are now  ubiquitous in astronomy; undergraduate curricula have been slower to train students in a systematic fashion in these skills. At Michigan State University, astronomy students are required to complete a senior thesis. We have been dissatisfied with the preparation of students for longer, open-ended research projects, such as that of a typical two-semester research project. Another motivation for redesigning AST 208 is that this course is the first rigorous course in the astronomy major. The prerequisite course, AST 207, serves as more of a broad survey over the entire field, whereas AST 208 contains a laboratory (observing) component and explores in more depth planetary science. Traditionally the course followed its title---\emph{Planets and Telescopes}---with the lecture devoted to planetary science and the lab devoted to observing. We felt that a tighter integration of the lecture and lab would serve the students better.
