Physics
Modeling Method at ASU
’95 & ’96
Students design their own experimental
procedures
Students must justify their interpretations of
data in teacher-guided Socratic dialogs
Models created from experimental
interpretations are deployed in carefully
selected problems, each of which is designed to
illustrate aspects of the model
Solutions are presented by students to the
entire class on whiteboards
The model is distributed over multiple
representations
Symbolic Representations
Verbal
Physical
System
Algebraic
Diagrammatic
Graphical
Mental
Model
Multiple Representations
a particle moving at constant velocity
with explicit statements describing relationships
’98 Curriculum Problem
Principles of Technology
Was not challenging our best students
Out of field teacher
Biology major
Proposed Solution
Invert the curriculum
Offer Modeling Physics to freshman
Barriers to Implementation
Convince the district curriculum
committee
Status quo of physics last
Physics is too hard
State Assessments
Why physics first
Build knowledge of science and the
concurrent use of mathematics
following the hierarchical nature of
science as it has unfolded over the
past century
More students take advanced
science
Improved college entrance exam
scores

World of Fun Physics Olympics
Measurement on rides and a one
hour multiple choice test
Physics students from a four state
area compete
A. P. Students are included
First time freshman students enter
the event
Physics Olympics Results
One freshman group earned
honorable mention recognition
All groups scored above the average
