\subsection{About AST 208}  AST 208 is the first rigorous course in the astronomy major. Its 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 \citep[using, e.g.,][]{Lissauer2013Fundamental-Pla}. The marriage of a lecture-based planetary science course with a laboratory course on observational practice came about as a quirk of history. Indeed, in previous editions of the course these two components operated independently.  We felt that a tighter integration of the lecture and the  lab would improve student gains competency  in using statistical techniques statistics  and numerical analysis  tools. \subsection{An integrated approach to learning outcomes across the major}
