|
||||
One common source of error in video analysis is camera movement. The paper describes a simple frame of reference correction that students can employ to salvage otherwise corrupted video analysis data. Two examples are provided.

Science and Social Policy classes are full of bespoke units and involve many different contexts. Starting the class with a discussion of food energy is a nice way for everyone to start with the same context. In addition, discussion of Food Energy can lead to interesting historical claims.

The work would not have been possible without Mark Hoyoak's excellent videography. Thanks also to Eugenia Etkina for introducing me to video analysis many years ago. Thanks also to Peter Bohacek for his inspiring talks and amazing Direct Motion Video examples.
|
||||
The work was prompted in part by discussions with John Deming, Carl Ferkinhoff, and Sarah Taber.

There are many copies of this video on the web. It seems that the original video was taken by Mark Hoyoak of KPAX News in Montana on September 9, 2003. The clip was subsequently featured on national news and comedy programs. For an overview, see \url{https://www.youtube.com/watch?v=jB47Vucoj2o} .
