Chemistry Workshop: A Modeling Approach to the Gas Laws
Saturday, January 25, 2014 from 10:00 AM to 1:00 PM (EST)
San Francisco, California
London, United Kingdom
WORKSHOP LEADERS: Donghong Sun and Tammy Gwara (Chemistry Teachers, Trinity School, New York, NY)
The gas laws are usually presented in chemistry textbooks as a set of equations. Students are then required to memorize these equations and plug in numbers to solve problems. In this workshop, you will gain direct experience with Modeling Instruction – a process through which students can reach understanding of the gas laws as proportional relationships by interpreting experimental results and building graphical representations of a particle view of gas behavior. Students can then apply their proportional reasoning skills in other areas of study and in real life.
We will be collecting and analyzing data (in “student mode”) in three experiments to develop the relationships between gas pressure and the volume, the number of particles, and the temperature. These relationships will be interpreted and represented by drawing particle diagrams based on our understanding of particle behavior of gases. We will then apply these relationships to solve problems by beginning with the meaning of proportional relationships, rather than by simply plugging numbers into a set of equations. Finally, in “teacher mode,” we will critique and discuss our experience and the classroom/pedagogical implications
Please bring a laptop if possible and install the data analysis software (Vernier Logger Pro) ahead of time. After you have registered for this workshop, we will send you the links and passwords required to download and install the software.
This workshop uses the Modeling Instruction approach and is a sample of the upcoming intensive 3-week Summer 2014 Chemistry Modeling Instruction Workshop (Dates are Monday July 21 through Friday, August 8. Register Kfor the summer workshop at: ).

When & Where
STEMteachersNYC (an affiliate of the American Modeling Teachers Association)
STEMteachersNYC (originally PhysicsTeachersNYC) was founded in summer of 2011 by a group of teachers as a teacher-led physics study group. The founders were all practitioners of Modeling Instruction, developed by university and high school physics teachers over the past 20 years through a collaborative process that continues as one of the primary activities of the American Modeling Teachers Association. STEMteachersNYC is affiliated with the AMTA and conducts 3-week summer modeling workshops as well as monthly 3-hour meetings on weekends during the school year. PTNYC is devoted to excellence in science teaching with a general focus on modeling instruction and similar approaches.
Modeling Instruction. The use of modeling in teaching was pioneered by Robert Karplus in his 1969 textbook, "Introductory Physics: A Modeling Approach. Modeling Instruction was subsequently developed at Arizona State University by David Hestenes, Malcom Wells, and Gregg Swackhamer, as well as by many others across the country. Over 500 teachers have taken teacher-led Modeling Instruction workshops in the summer, and the best way to learn about Modeling Instruction is by taking a summer workshop. If you'd like to read more about it, go to American Modeling Teachers Association or take a look at the Chapter 1 of Introductory Physics by Robert Karplus (book) or (eBook -- use "guest" for login and password).
