          Based on the success of the first version of our computer coaches for solv-
        
        
          ing problems in introductory physics, the University of Minnesota Physics
        
        
          Education Research Group has been developing its second generation,
        
        
          Customizable Computer Coaches for Physics Online (C3PO). In this
        
        
          poster, we describe the lessons learned from testing the first version of the
        
        
          coaches with hundreds of students and how the results impact the second
        
        
          version of the system.

          An introductory physics problem-solving framework is desirable for
        
        
          students to develop problem-solving skills. However, a potential obstacle
        
        
          to developing this framework, even with an explicit intervention, is with
        
        
          regard to student attitudes and approaches to problem solving. Com-
        
        
          puter coaches, developed at the University of Minnesota for introducing
        
        
          a problem-solving framework, are examined with respect to data taken
        
        
          from a reflection activity performed by students in an introductory physics
        
        
          for life science (IPLS) course. The activity consisted of students working
        
        
          on a problem in lab groups and recording aspects of the problem solving
        
        
          process in which they struggled. These recorded struggles are compared to
        
        
          the computer coaches’ different problem solving steps.

          Students in an entry-level undergraduate physics course engaged in short
        
        
          Interactive Video Vignettes (IVVs) outside of class in order to enrich their
        
        
          understanding of specific physics concepts. Prior work by the LivePhoto
        
        
          Physics Group suggests that students enjoy using IVVs and that their
        
        
          use does improve learning, but not to the same extent for every IVV. The
        
        
          research question for this study is: What characteristics of Interactive
        
        
          Video Vignettes help or hinder student learning in introductory physics
        
        
          courses? The purpose of this explanatory sequential mixed methods study
        
        
          (Creswell & Plano Clark, 2011) is to begin explaining the thoughts, opin-
        
        
          ions, and perceptions regarding the use of IVVs for roughly 15 students in
        
        
          an entry-level undergraduate physics course. This poster reports the results
        
        
          of a survey given to students during the course, interviews conducted after
        
        
          the course, and integration of these data. Supported by NSF grants DUE-

          The solutions to mathematics and science problems with multiple variables
        
        
          often rely upon the geometric relationships between mathematical objects.
        
        
          For most calculus and physics students, this geometric reasoning occurs
        
        
          after their algebraic understandings—if at all! This poster shows a new ap-
        
        
          proach to multivariable calculus which lets students discover the geometric
        
        
          properties of mathematical objects before introduction with algebraic
        
        
          expressions. As a result, students are able to discuss the geometric (includ-
        
        
          ing coordinate dependent and independent) properties of such concepts as
        
        
          gradient, directional derivatives, level curves, integrals, and partial deriva-
        
        
          tives. Come explore how these physical surfaces help students bring their
        
        
          geometric knowledge of calculus to the surface and discuss how these tools
        
        
          could help physics students explore important quantities in physics.
