2. We have been examining and producing1-3 video vignettes of physics teaching practices for some time with the intent of fostering better practices4-6 for student physics learning. In this session we will view and analyze an unusually discourse-rich modeling physics vignette taken from an unusually successful community college physics classroom together. A brief description of the Reformed Teacher Observation Protocol (RTOP) will also be presented.

4. Video of effective (as measured by student conceptual score gain from pre- and post-testing with the Hestenes’Force Concept Inventory) and deliberately nontraditional mechanics instruction of community college students. • What is going on in this classroom? • What events are promoting learning? • Watch the video and make a few notes on noteworthy behaviours that are taking place that you believe are promoting learning.

5. Roughly three main sections: • student data gathering activity • student circle whiteboarding discourse, • teacher warranting knowledge and setting up next activity (relative sizes and cues)

6. Student data gathering • students enter class and go right to work (cued from last day “model how a ball bounces”) • students obviously comfortable with working on own • student tools and representations “hammers” are whiteboarding, SONAR and x-v-a vs. t plots • teacher is seeding different groups with different questions – pushing in different directions, different parts of the puzzle • unique tool to some groups – energy pie charts

7. Circle Whiteboarding • student trained in taking turns and sharing the air • explicit use of model building and selection is evident • new tool (energy pie chart analysis) gets significant billing • jargon control (noun Nazis) emphasizes student thought

8. Teacher warranting knowledge • advanced language control -- vocabulary manipulation (grudgingly allows new jargon, focuses on few but critical issues) • warrants certain classroom learning (or forces agreement) • sharply limited “closure” setting up next

9. Overall • student meaning centered class • highly motivated and on-task group (sense of control and empowerment) • student discourse intensive (Vygotski) • lots of active instructor manipulation of classroom activity, environment and student thought (loaded balls) • strong scientific thought – observational, phenomenological, theory building, much discourse, hopefully will see prediction and testing yet to come • quite Machiavellian actually
