For example, Mayan people of San Pedro use collaboration in order to build upon one another's ideas and activities. Specifically, many learning practices focus on "role-switching." When learning a new task, people alternate between helpful observer and active participant. Mayan mothers do not act as teachers when completing a task with their children, but instead collaborate with children through play and other activities. People of this Mayan community use the shared endeavors method more than European-Americans who tend to use the transmit-and-test model more often. The shared endeavors model is when people go off of others ideas and learn from them, while the transmit-and-test model is what is used in most American schools when a teacher gives students information and then tests the students on the information. The shared endeavors model is a form of collaborative learning because everyone learns from one another and are able to hear and share others' ideas.
