This app is designed to make it easier to track, record, and share the results of a classroom observation. It makes use of the COPUS protocol (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3846513/). It was designed using the materials found at http://www.cwsei.ubc.ca/resources/COPUS.htm .
There is one difference between the original protocol and the implementation. The app allows you to specify student engagement for each student activity rather than one student engagement level for each time interval. If you wish to use the original method, use the top student engagement menu option and ignore the others.
