Some data highlighted in reports published in 2013 on Canadians’ literacy level are concerning, particularly among Quebecers. Recent statistics indicate that 14.2% of the adult population, aged between 16 and 25, does not reach a literacy’s level required to function in everyday life (Statistics Canada, 2013).To ensure that tomorrow's adults reach in greater numbers the literacy level required, it is important to act early in schooling. Knowing that today communications complexity requires increasingly high literacy skills (Canadian Council on Learning [CCL], january 2008), this finding is worrying. The mastering of informational competencies related to multiple texts' reading and understanding (digital or printed texts which combine two semiotic modes) refers to the concept of multimodal media literacy (MML). This concept includes motivation's aims (Lebrun, Lacelle and Boutin, 2013) that deserves to be thorough as it currently very little developed. Therefore, this research focuses on MML's pedagogical practices, in French's class, deemed motivating by disadvantaged backgrounds' Cycle 3 students'.
