          This study presents a methodology for characterizing the structure and
        
        
          nature of large group discussions in a Physics and Everyday Thinking --
        
        
          High School (PET-HS) classroom. The PET-HS curriculum was developed
        
        
          to model scientific induction and relies on collaborative discussions to
        
        
          facilitate student sense-making and consensus about the course’s learning
        
        
          targets. The analytical framework presented here was designed with the in-
        
        
          tent of identifying the contributions from teacher, individual student, and
        
        
          groups to the discussions. Specifically, this analysis helps track how differ-
        
        
          ent actors are interacting with each other. Two-dimensional and three-
        
        
          dimensional representations are used for highlighting different dialogue
        
        
          patterns. Results yield information on equity of participation, changes in
        
        
          the structure of discussions throughout a class period and school year. By
        
        
          superposing these data with data on the substance of the discussions, we
        
        
          can infer the types of moves that drive the conversation. Implications for
        
        
          running productive discussions and trade-offs will be discussed.

          The talk will discuss how IWB was used in an advanced way that incor-
        
        
          porates students’ meaningful creative, graphical, and kinesthetic input
        
        
          as a key part of a learning sequence in a Slovenian high school. We have
        
        
          learned from a previous pilot study in the same school that the IWB
        
        
          is mostly used in a way that does not take advantage of touch technol-
        
        
          ogy affordances, but rather mirrors well-established patterns of classic
        
        
          whiteboard use and the use of a computer-projector setup. In our study,
        
        
          two lessons were designed and implemented, one on the topic of Kepler’s
        
        
          laws and the other on geometrical optics. We have observed how teachers
        
        
          and students respond to new activities and changes in classroom dynamics.
        
        
          Through in-depth interviews with students and teachers, we have probed
        
        
          their perceptions of the IWB as a learning and teaching tool and perceived
        
        
          benefits and drawbacks of truly interactive IWB use.

          Modern physics and in particular quantum mechanics (QM) is a cultural
        
        
          need for new generation citizens and it will be an official part of the
        
        
          secondary school curriculum starting from next year. Nonetheless, how
        
        
          to teach it is still an open question. Quantum incompatibility as a central
        
        
          feature of the new physical behavior is the goal of a design-based proposal
        
        
          focused on building theoretical thinking in approaching QM in second-
        
        
          ary school. In the contexts of polarization and spin, the vector description
        
        
          of the quantum state of a system emerges as interpretative hypothesis
        
        
          in phenomena explored by students. The connection between physical
        
        
          systems and processes on the one side and their formal description on the
        
        
          other side is analyzed by visualizing relations between entities representing
        
        
          system properties and relations between corresponding state vectors. Data
        
        
          on students’ reasoning in step-by-step educational intervention modules
        
        
          have oriented the global path proposed.

          Florida International University is the largest source of STEM bachelors
        
        
          and masters degrees for Hispanic students. Thus, the students participat-
        
        
          ing in the FIU physics teacher education program both represent a diverse
        
        
          cultural background and will most likely teach in a diverse community.
        
        
          Two hallmarks of our program are Modeling Instruction and attention to
        
        
          developing communities. In this talk we discuss these two features as they
        
        
          pertain to preparing pre-service teachers for the diverse community of
        
        
          South Florida. As well we look forward to the implementation of FIUTeach
        
        
          as a further evolution of the teacher education programs.

          Too often in public discourse about urban education deficit thinking pre-
        
        
          dominates with a focus on what students cannot do and the standardized
        
        
          tests that illustrate their failure. Alternatively, new teachers are more effec-
        
        
          tive when they seek to help students build on their intellectual resources
        
        
          and capabilities. As we prepare our pre-service science teachers at Chicago
        
        
          State University, we focus on four elements: inquiry-based learning
        
        
          environments in science, early teaching experiences, explicit attention in
        
        
          pedagogical content knowledge courses on student resources rather than
        
        
          student deficits, and an emphasis on the professional nature of teaching. As
        
        
          a minority serving institution on the South Side of Chicago, our pre-ser-
        
        
          vice teachers often have experienced the impacts of deficit thinking in their
        
        
          own educational journeys. Inquiry learning and early teaching experiences
        
        
          build on our science pre-service teachers’ resources while simultaneously
        
        
          modeling attitudes for the K-12 classroom.

          Diversity in Colorado K-12 schools has taken on a new meaning in the
        
        
          past four years. We are no longer merely facing diverse socio-economic
        
        
          backgrounds. 25% of the students in our local district speak English as a
        
        
          Second Language (ESL) and over 10% are recent refuges to America. This
        
        
          past year there were 54 languages spoken in one local high school with
        
        
          many of the students entering school for the first time in their lives. One
        
        
          might think that science teachers would be insulated from many of these
        
        
          challenges, unfortunately various pressures in the school system result
        
        
          in this same diversity in the science classroom. The good news is that
        
        
          techniques that are effective for teaching ESL learners are consistent with
        
        
          techniques for effective instruction in science.
