What is an .CMA file?

.CMA is Coach Activity File

Activity file created and used by Coach, a Dutch computer modeling program that allows users to make dynamic models; stores a measurement or control activity with all the elements that appear in the document, such as pictures, videos, and text; stored in Coach project folders.

CMA activity files and .CMR results files contain similar data except activity files only contain the activity. Results files contain the results of a student's work in the activity file.

NOTE: Coach is a program designed for students between the ages of 8 and 20. It is typically used in schools because of its teaching tools.
