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.

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