          questions, and various other activities. One of these two courses, PHGN
        
        
          440, is a senior-level elective on solid state physics. The other, PHGN 462,
        
        
          is a core course on electrodynamics. In this poster we’ll report on methods,
        
        
          motivations, and data, including but not limited to Youtube analytics, a
        
        
          qualitative survey, course evaluations, and a PER-based content inventory.

          An important goal of graduate physics core courses is to help students
        
        
          develop expertise in problem solving and improve their reasoning and
        
        
          meta-cognitive skills. We explore the conceptual difficulties of phys-
        
        
          ics graduate students by administering conceptual problems on topics
        
        
          covered in undergraduate physics courses before and after instruction in
        
        
          related first year core graduate courses. Here, we focus on physics graduate
        
        
          students’ difficulties manifested by their performance on two qualitative
        
        
          problems involving diagrammatic representation of vector fields. Some
        
        
          graduate students had great difficulty in recognizing whether the diagrams
        
        
          of the vector fields had divergence and/or curl but they had no difficulty
        
        
          computing the divergence and curl of the vector fields mathematically. We
        
        
          also conducted individual discussions with various faculty members who
        
        
          regularly teach first-year graduate physics core courses about the goals of
        
        
          these courses and the performance of graduate students on the conceptual
        
        
          problems after related instruction in core courses.

          Electrostatics Diagnostic (CUE), provide rich, fine-grained information
        
        
          about students’ reasoning. However, because of the difficulties inherent
        
        
          in scoring these assessments, the majority of the large-scale conceptual
        
        
          assessments in physics are multiple-choice. To increase the scalability and
        
        
          usability of the CUE, we set out to create a new version of the assessment
        
        
          that preserves the insights afforded by a free-response format while ex-
        
        
          ploiting the logistical advantages of a multiple-choice assessment. We used
        
        
          our extensive database of responses to the free-response CUE to construct
        
        
          distractors for a new version where students can select multiple responses
        
        
          and receive partial credit based on the accuracy and consistency of their
        
        
          selections. Here, we offer examples of the questions and scoring of this new
        
        
          coupled multiple-response CUE. We also present a direct comparison of
        
        
          test statistics for both versions and potential insights into student reason-
        
        
          ing from the new version.

          The flipped classroom is gaining popularity as a way of blending the best
        
        
          of online and in-person education, but efforts so far have been mostly
        
        
          (though not exclusively) focused on introductory classes. At CSM, we have
        
        
          developed and implemented two upper-division physics courses that use
        
        
          full or partial flips. Students are asked to watch one or more videos before
        
        
          class as preparation, with the actual class period occupied by Q&A, clicker

          Here’s how it works:
        
        
          Your students take a 40-question,
        
        
          45-minute, multiple-choice test in March 2015 under
        
        
          your school’s supervision. Exam questions are based
        
        
          on topics and concepts covered in a typical high
        
        
          school physics course. Winners will be announced
        
        
          and awarded prizes the first week of May.
