Checking your model
When it is time to check your model, the professor will look at your target statement and the model you created. The professor will check to see if your model explains the target of the model.
You can tell if the professor is happy with your model if you look at his face on your screen.
If your model could explain your model target, but some things are unclear, the professor looks confused.
If your model explains your model target, the professor smiles.
WARNING: The professor checks to see if you made the model so that the behavior of the model matches your predictions. He doesn't check to see if your prediction was right in the first place. He also doesn't check to see if your model is missing anything or has the wrong processes and basic objects in it.
How does the professor know if your model explains the target?
The professor looks at your prediction and then checks to see if the processes and influences are changing it in a way that matches your prediction. Here is an example. If the professor looks at this model and prediction, what would he say?
ADD
PREDICTION ON LEVEL OF WATER
The professor starts by looking at the processes in the model. This model only has one process, filling, and it increases the amount of water. Since the model says that amount of water influences level of water, the professor knows that the level of water is increasing if the amount of water is increasing. This model matches the prediction about level of water.
There is another prediction on temperature. No processes are affecting temperature so it is unchanging. The model does not match the prediction on water temperature.
