The principal objective of this methodological article based on an exploratory qualitative research project is to show one way in which researchers can approach the field and make the necessary adjustments based on the actual situation in order to complete their work. The article examines multiple case studies on collaboration in team cycles in Québec primary schools. The thesis project was designed and carried out from a psycho-sociological angle, more precisely using an approach centered on the development of the power to act of people and communities (DPA-PC) (Le Bossé, 2012, 2016). It seemed to be hard to get several members of the three participating school teams to participate in semi-directed individual interviews. Five strategies were put forward for a bottom-up sampling process. The choice of semi-directed individual interviews was found to be appropriate for giving access to various dynamics in primary school teams and for increasing personal awareness.
