Based on our experience with this semester's edition, we will expand the pre-test to include problems on statistics and ``foundational'' topics in astronomy, such as the inverse square law flux. These pre-test questions are asked again on the final to provide a measurement of the student gain (eq.~\ref{eqn:gain}). This allows us to assess how well we are doing as we make further changes to the course.  Our revisions to the course are thoroughly documented, so that future editions can take advantage of our efforts.  The material for the lectures, including syllabus, notes, \ipython\ notebooks, pre-test, and quizzes, is currently stored in a private git \href{http://git-scm.com/}{git}  repository. At the end of the Spring 2015 semester, the notes and \ipython\ notebooks will be forked into a public \href{https://github.com/}{GitHub} repository; exams and solutions will remain in the private repository and will be available upon request. This ensures that the archived course materials can be easily disseminated.
