A year ago, I wrote about my attempt to integrate Angry Birds as part of my quadratic modeling unit. I was certainly not the first, and there have been many others that have taken this idea and run with it. This is definitely a great way of using the concept of fitting parabolas to a realistic task that the students can have fun completing.
As I said a year ago, however, the bigger picture skill that is really powerful with modeling is making do with less information. I incentivized my students last year to come up with a model that predicts the final location of the collision of a bird earlier than everyone else. In other words, if Thomas is able to predict the correct final location with ten seconds of data, while Nick is able to do so with only seven, Nick has done the better job of modeling. I did this by asking the students to try to do this with the earliest possible frame in the video.
Each group of students will calculate the ratio for each video using Geogebra. Some videos reveal more about the path than others. I’ll sum the errors, rank the student groups based on cumulative error, and then we’ll have a great discussion about what made this difficult.
The sensitivity of a quadratic (or any fit) fit to data points that are close together is what I’m targeting here. I’ve tried other techniques to flesh this out in students before – I still get students ‘fitting’ a table of data by choosing the first two or three points. I’m hoping this will be a bit more interesting and successful than my previous attempts.
