Lessons from America A success story in high school physics education. Presented by Barbara McKinnon, JMSS
2. What is successful about Modeling Instruction? 3. What are the implications for the Australian curriculum? 1. What is Modeling Instruction?
Scientific Thinking • Constant Velocity • Constant Acceleration • Force causing change in velocity • Force as an interaction • Force diagrams and net force • Relationship between force and acceleration • Friction • 2D motion • Energy (storage and transfer via working, heating, radiating) • Circular motion • Impulsive forces (conservation of linear momentum) Modeling Mechanics Curriculum
90 hours of professional development consisting of • intensive immersion in the mechanics modeling curriculum and pedagogy • discussion of research literature • building connections with the modeling teaching community Mechanics Modeling Workshops
Traditional instruction does not effectively address misconceptions • For many students, traditional instruction is not successful in teaching conceptual understanding or scientific reasoning Why is a new pedagogy needed?
Students actively engaged in construction of a phenomenological model based upon their own observation and experimentation deployment of the model in problem solving and testing model breaking What the students say about modeling What is modeling?
Multiple representations Small whiteboards to facilitate presentation of ideas Socratic questioning Essential Tools
Effective scientific reasoners who have advanced problem solving skills. How is this measured? Performance on conceptual assessment instruments such as Force Concept Inventory Results on conventional statewide tests. Retention of students in Science Outcomes

Modeling curricula have been written for • Chemistry • Biology • Humanities – English and History Is modeling only for Physics?
Modeling is about creating multiple connections between the physical system and mental model.
Modeling takes more time, can’t cover as much curriculum. • The Physics First experience: • Students in Year 9 spend a year doing Physics using modeling • Improves outcomes in Chemistry and Biology • Increases retention in Science • Don’t have to teach everything using modeling for procedural benefit to be retained. Points to consider
Using a modeling approach find that • Students are engaged • Students improve their reasoning through communication of their scientific thinking and by debating with peers. • Students achieve a deeper conceptual understanding and become better problem solvers • Students increase their learner confidence by building their own conceptual framework. • Both girls and boys respond well to approach. Modeling instruction is a demonstration of the power of teaching informed by education research. Outcomes in the USA
Modeling has been found to be most successfully delivered when teacher has attended a three week workshop. • Whiteboard discussions best suited to groups of 15-24

Models can be descriptive or explanatory 3. A model must have predictive power 4. The predictive power of the model has limitations The essence of modeling
Implement modeling fundamentals in teaching practice • Evaluate teaching of mechanics in Physics at JMSS using the Force Concept Inventory • Learn more about the application of the modeling method to other areas of Physics and the other sciences. • Build a modeling community in Australia My goals

Barbara McKinnon would like to acknowledge • the generosity of her school, the John Monash Science School in awarding her the first JMSS staff fellowship, • Boeing for subsidising the cost of the accommodation during the three week workshop, and • the American Modeling Teachers’ Association for allowing her to participate in the workshop.
