I think it is the correct definition within the context;
"Participant observation is a qualitative research method in which the researcher not only observes the research participants, but also actively engages in the activities of the research participants. This requires the researcher to become integrated into the participants' environment while also taking objective notes about what is going on. Most researchers who conduct participant observations take on the role that they are interested in studying. In Jill's case, she might enroll in an actual foreign language course, complete all assigned homework and classwork, and attend field trips just as any regular student enrolled in the class would. Jill would also have informal conversations with other students in the class and the teacher. Jill would keep a detailed record of all assignments and take detailed notes about what she observes and what happened during her encounters with her classmates and teachers. Jill would also keep notes about technology usage, classroom norms and expectations, and any other information that she finds useful."
