									This CS & IT Symposium presentation has two parts—this
Powerpoint presentation and an Excel workbook/spreadsheet
with multiple sheets. The presentation: provides some
background; outlines activities using the spreadsheet; closes
with some assessment suggestions and resources. Examine the
presentation in "notes page" view. If that is not available,
download a version from Philip's Web site at:

The spreadsheet is available at:

Modeling


   What is it

   Need for simulation

   Why use modeling and simulation
Benefits of Using Modeling
(& Simulation) in Education

   Benefits from problem-based activities
    (creating and implementing models)

   Benefits related to computer use

   Benefits of working with teachers of other
    disciplines
Teaching Using Modeling
(& Simulation)
   Advantages of/options with modeling

 Various goals
 Using versus developing models


 Can use existing lessons
 Can develop your own lessons
Some Caveats
   Centralized and decentralized models

   Correctness of models and simulations
    Always remember, the model and/or
    simulation can be wrong
A Sample Model & Simulation
   Lots of things to model & tools to use

   Alternatives within population modeling

   Our goal–use population to illustrate the use
    of spreadsheets in modeling & simulation
Population Model/Simulation #1
 Simple model & simulation (sheet “One”)
 Initial conditions & assumptions
 Short term results
 Longer term results
 Eventual results


   Accuracy of the model? the simulation?
Fixing Our First Attempt
 Fixing the first attempt (sheet “Two”)
 The new results?


   Variations in reproduction?

   Is the model accurate? Does it represent
    what we wish it to?
Making Peeps more like People
   Making model & simulation more “human”

   Vary survival rates by age (sheet “Three”)
    [another sheet shows how rates were determined]



   Vary survival rates by year (sheet “Four”)
Making Peeps more like People
(continued)



   Add possibility for catastrophe (sheet “Five”)

   Discussion
Remember to Assess your
Instruction
   Revisit the goals

   Were they met? How do you know?

   What can I (the teacher) learn to improve
    my future teaching?
Wrap Up


   Questions?

   Discussion?
Resources
