All parameters are found by minimizing the sum of square errors between model prediction (here ) and actual data (here hi).
for the model (Model 3):
This requires numerical solution of our model over a region of parameters k1 and k2to determine the minimum of SSE(k1,k2) in our parameter space (k1, k2, SSE(k1,k2)).
Day before modeling activity ask students to think about how theywould model just how long it takes an ant to dig a tunnel of length x.
Assumptions!!!!! LEAD TO Mathematics!!!!!
See you next class with your ideas!
Example of “local flipping” or “flipping in the small” in this case modeling first leading to differential equation mathematics.
Ask questions of solved differential equations model such as
“What if we double the length of the tunnel? Does this double the time?”
Consensus emerges. . . .
. . . and what mathematics does this yield?
Ask students to think about how a kidney dialysis machine works . . .
. . . . . . on the day before class for modeling such a machine.
